Patent Application
20160050929
The present invention relates to a method of controlling insects (in particular insects of the order Hemiptera, especially aphids and whitefly) that are resistant to neonicotinoid insecticides, to methods of controlling insects whereby undesired insects are affected but beneficial arthropods are not affected, using compounds of formula I (where A, R1 and R2 are as defined below),
and, further, to novel compounds of formula I which are useful in the aforementioned methods and/or which possess enhanced insecticidal properties, and to compositions containing said compounds.
Bicyclic amine derivatives with insecticidal properties are disclosed, for example, in WO9637494.
There is a continuing need to find new methods of controlling resistant insect populations, as well as more selective methods of controlling insects whereby undesired insects are affected but beneficial arthropods are not affected, and additionally biologically active compounds suitable for use in the aforementioned methods, as well as new biologically active compounds displaying superior properties for use as agrochemical active ingredients (for example, greater biological activity, a different spectrum of activity, an increased safety profile, improved physico-chemical properties, or increased biodegradability).
The damage of plants, and in particular commercial crops, has resulted in large amounts of resources and efforts being spent attempting to control the activities of Hemiptera.
Plants exhibiting aphid damage can possess a variety of symptoms, such as decreased growth rates, mottled leaves, yellowing, stunted growth, curled leaves, browning, wilting, low yields and death. The removal of sap creates a lack of vigour in the plant, and aphid saliva can also be toxic to plants. Many Hemipteran species, transmit disease-causing organisms like plant viruses to their hosts. The green peach aphid (Myzus persicae) is a vector for more than 110 plant viruses. Cotton aphids (Aphis gossypii) are also vectors of several economically important viruses. Whiteflies feed by tapping into the phloem of plants, introducing toxic saliva and decreasing the plants' overall turgor pressure. Since whiteflies congregate in large numbers, susceptible plants can be quickly overwhelmed. Further harm is done by mold growth encouraged by the honeydew that both aphids and whiteflies secrete.
The neonicotinoids represent the fastest-growing class of insecticides introduced to the market since the commercialization of pyrethroids (Nauen & Denholm, 2005: Archives of Insect Biochemistry and Physiology 58:200-215) and are extremely valuable insect control agents not least because they had exhibited little or no cross-resistance to older insecticide classes, which suffer markedly from resistance problems. However, reports of insect resistance to the neonicotinoid class of insecticides are on the increase.
The increase in resistance of such insects to neonicotinoid insecticides thus poses a significant threat to the cultivation of a number of commercially important crops, fruits and vegetables, and there is thus a need to find alternative insecticides capable of controlling neonicotinoid resistant insects (i.e. to find insecticides that do not exhibit any cross-resistance with the neonicotinoid class).
Resistance may be defined as “a heritable change in the sensitivity of a pest population that is reflected in the repeated failure of a product to achieve the expected level of control when used according to the label recommendation for that pest species”. (IRAC)
Cross-resistance occurs when resistance to one insecticide confers resistance to another insecticide via the same biochemical mechanism. This can happen within insecticide chemical groups or between insecticide chemical groups. Cross-resistance may occur even if the resistant insect has never been exposed to one of the chemical classes of insecticide.
Two of the major mechanisms for neonicotinoid resistance include:
The cytochrome P450 monooxygenases are an important metabolic system involved in the detoxification/activation of xenobiotics. As such, P450 monooxygenases play an important role in insecticide resistance. P450 monooxygenases have such a phenomenal array of metabolizable substrates because of the presence of numerous P450s (60-111) in each species, as well as the broad substrate specificity of some P450s. Studies of monooxygenase-mediated resistance have indicated that resistance can be due to increased expression of one P450 (via increased transcription) involved in detoxification of the insecticide and might also be due to a change in the structural gene itself. As such, metabolic cross-resistance mechanisms affect not only insecticides from the given class (e.g. neonicotinoids) but also seemingly unrelated insecticides. For example, cross-resistance relationships between the neonicotinoids and pymetrozine in Bemisia tabaci have been reported by Gorman et al (Pest Management Science 2010, p. 1186-1190).
It has now been surprisingly found that certain bicyclic amines can be successfully used to control neonicotinoid resistant populations of insects in the Hemiptera order.
Thus, in the first aspect of the invention there is provided a method of controlling insects from the order Hemiptera which are resistant to one or more of the neonicotinoid insecticides, which method comprises applying to said neonicotinoid resistant insects a compound of formula (I):

or an agrochemically acceptable salt, N-oxide or isomer thereof.
Surprisingly, compounds of formula (I) are able to control insects that are resistant to neonicotinoid insecticides whereby resistance is a result of either of the aforementioned mechanisms (target site or metabolic).
Further, it has also been surprisingly found that compounds of formula (I) possess an advantageous safety profile with respect to beneficial arthropods, in particular beneficial insects & predatory mites. More particularly, Orius insidiosus, Orius laevigatus, Orius majusculus, Coccinella septempunctata, Adalia bipunctata, Amblydromalus limonicus, Amblyseius andersoni, Amblyseius barkeri, Amblyseius califomicus, Amblyseius cucumeris, Amblyseius montdorensis, Amblyseius swirskii, Phytoseiulus persimilis, Syrphus spp., and Phytoseiulus persimilis. Most particularly, Orius laevigatus.
Beneficial arthropods form a key component in integrated pest management systems. Such systems have the advantage that they are able to reduce the use of chemical agents, which provides many subsequent environmental and economic benefits & advantages. A variety of arthropods can be present whereby a grower may wish to eliminate one or more arthropod pests using a chemical insecticide whilst minimising the impact on the population of beneficial arthropods in the immediate area. However, the fact that beneficial arthropods share certain biological similarities with agricultural arthropod pests presents a significant challenge. Arthropod pests attack a plant by biting, chewing, sucking, or burrowing into the plant tissue, whereas a beneficial arthropod will most typically only use a plant as a physical support. Nevertheless, beneficial arthropods are exposed to the same environmental conditions (including chemical agents, such as insecticides) as their pest counterparts. One group of arthropods that have more intimate contact with plant materials, and which are of significant benefit to growers, are pollinators (such as honeybees). Accordingly, there is a need for new methods, compounds and compositions for controlling insects whereby undesired insects are affected but beneficial arthropods are not.
Thus, in a second aspect of the invention there is provided a method of controlling insects from the order Hemiptera whereby undesired insects are affected but beneficial arthropods are not affected, which method comprises applying to the insects a compound of formula (I).
In a further aspect of the invention there is provided a method of controlling insects from the order Hemiptera which are resistant to one or more of the neonicotinoid insecticides and whereby undesired insects are affected but beneficial arthropods are not affected, which method comprises applying to said neonicotinoid resistant insects a compound of formula (I).
The compounds of formula (I) can be applied in combination with beneficial arthropods, in particular beneficial insects & predatory mites. This has the advantage that lower rates of the compounds of formula (I) can be applied to effectively control the target pest. Beneficial arthropods are useful in the control of a variety of pest species. Onus bugs in particular feed on inter alia aphids and whiteflies.
Thus, in a yet further aspect of the invention there is provided a method of controlling insects from the order Hemiptera which are resistant to one or more of the neonicotinoid insecticides, which method comprises applying to said neonicotinoid resistant insects a compound of formula (I) and one or more beneficial arthropods.
Preferred beneficial arthropods are beneficial insects & predatory mites. More preferably, Orius insidiosus, Orius laevigatus, Orius majusculus, Coccinella septempunctata, Adalia bipunctata, Amblydromalus limonicus, Amblyseius andersoni, Amblyseius barkeri, Amblyseius califomicus, Amblyseius cucumeris, Amblyseius montdorensis, Amblyseius swirskii, Phytoseiulus persimilis, Syrphus spp., or Phytoseiulus persimilis. The most preferred being Orius laevigatus.
Preferably, the neonicotinoid resistant insects from the Hemiptera order which are controlled by the methods according to the present invention are insects from suborder Sternorrhyncha, especially insects from the Aleyrodidae family and the Aphididae family.
By virtue of the surprising ability of a compound of formula I to control such neonicotinoid resistant insects, the invention also provides a method of protecting a crop of useful plants, wherein said crop is susceptible to and/or under attack from such insects. Such a method involves applying to said crop, treating a plant propagation material of said crop with, and/or applying to said insects, a compound of formula I.
Since the compounds of formula I do not exhibit cross-resistance to neonicotinoid resistant Hemiptera, it may be used in a resistance management strategy with a view to controlling resistance to the neonicotinoid class of insecticides. Such a strategy may involve alternating applications of a compound of formula I and a neonicotinoid insecticide, either on an application by application alternation (including different types of application, such as treatment of plant propagation material and foliar spray), or seasonal/crop alternation basis (e.g. use a compound of formula I on a first crop/for control in a first growing season, and use a neonicotinoid insecticide for a subsequent crop/growing season, or vice versa), and this forms yet a further aspect of the invention.
As mentioned herein, not only are insects from the Hemiptera order pests of a number of commercially important crops, the viruses that these insects carry also pose a threat. With the emergence of resistance to neonicotinoid insecticides, the severity of this threat has increased. Thus, a further aspect of the invention provides a method of controlling a plant virus in a crop of useful plants susceptible to and/or under attack by neonicotinoid resistant insects which carry said plant virus, which method comprises applying to said crop, treating a plant propagation material of said crop with, and/or applying to said insects, a compound of formula I.
Examples of plant viruses that may be controlled according to this aspect of the invention include Sobemovirus, Caulimovirus (Caulimoviridae), Closterovirus (Closteroviridae), Sequivirus (Sequiviridae), Enamovirus (Luteoviridae), Luteovirus (Luteoviridae), Polerovirus (Luteoviridae), Umbravirus, Nanovirus (Nanoviridae), Cytorhabdovirus (Rhabdoviridae), Nucleorhabdovirus (Rhabdoviridae).
These viruses are spread preferably by insects which are one or more of as an example Acyrthosiphum pisum, Aphis citricola, Aphis craccivora, Aphis fabae, Aphis frangulae, Aphis glycines, Aphis gossypii, Aphis nasturtii, Aphis pomi, Aphis spiraecola, Aulacorthum solani, Brachycaudus helichrysi, Brevicoryne brassicae, Diuraphis noxia, Dysaphis devecta, Dysaphis plantaginea, Eriosoma lanigerum, Hyalopterus pruni, Lipaphis erysimi, Macrosiphum avenae, Macrosiphum euphorbiae, Macrosiphum rosae, Myzus cerasi F., Myzus nicotianae, Myzus persicae, Nasonovia ribisnigri, Pemphigus bursarius, Phorodon humuli, Rhopalosiphum insertum Wa, Rhopalosiphum maidis Fitch, Rhopalosiphum padi L., Schizaphis graminum Rond., Sitobion avenae, Toxoptera aurantii, Toxoptera citricola,Phylloxera vitifoliae, Bemisia tabaci, Myzus persicae, Nilaparvata lugens, Aphis gossypii, Trialeurodes vaporariorum, Bactericera cockerelli.
Methods of the invention as described herein may also involve a step of assessing whether insects are resistant to neonicotinoid insecticides and/or whether said insects carry a plant virus. This step will in general involve collecting a sample of insects from the area (e.g. crop, field, habitat) to be treated, before actually applying a compound of formula I, and testing (for example using any suitable phenotypic, biochemical or molecular biological technique applicable) for resistance/sensitivity and/or the presence or absence of a virus.
The term neonicotinoid insecticide as used herein refers to any insecticidal compound that acts at the insect nicotinic acetylcholine receptor, and in particular refers to those compounds classified as neonicotinoid insectides according to Yamamoto (1996, Agrochem Jpn 68:14-15). Examples of neonicotinoid insecticides include those in Group 4A and 4C of the IRAC (insecticide resistance action committee, Crop Life) mode of action classification scheme, e.g. acetamiprid, clothianidin, dinotefuran, imidacloprid, nitenpyram, thiacloprid, sulfoxaflor and thiamethoxam, as well as any compound having the same mode of action.
By the terms “control” or “controlling” as applied to insects, it is meant that the targeted insects are repelled from or less attracted to the crops to be protected. Additionally, as applied to insects, the terms “control” or “controlling” may also refer to the inability, or reduced ability, of the insects to feed or lay eggs. These terms may further include that the targeted insects are killed.
Thus the method of the invention may involve the use of an amount of the active ingredient that is sufficient to repel insects (i.e a repellently effective amount of active ingredient), an amount of the active ingredient that is sufficient to stop insects feeding, or it may involve the use of an insecticidally effective amount of active ingredient (i.e. an amount sufficient to kill insects), or any combination of the above effects. Where the terms “control” or “controlling” are applied to viruses it is meant that the level of viral infection of a crop of useful plants is lower than would be observed in the absence of any application of a compound of formula I.
The terms “applying” and “application” are understood to mean direct application to the insect to be controlled, as well as indirect application to said insect, for example through application to the crop or plant on which the insect acts as pest, or to the locus of said crop or insect, or indeed through treatment of the plant propagation material of said crop of plant.
Thus a compound of formula I may be applied by any of the known means of applying pesticidal compounds. For example, it may be applied, formulated or unformulated, to the pests or to a locus of the pests (such as a habitat of the pests, or a growing plant liable to infestation by the pests) or to any part of the plant, including the foliage, stems, branches or roots, to the plant propagation material, such as seed, before it is planted or to other media in which plants are growing or are to be planted (such as soil surrounding the roots, the soil generally, paddy water or hydroponic culture systems), directly or it may be sprayed on, dusted on, applied by dipping, applied as a cream or paste formulation, applied as a vapour or applied through distribution or incorporation of a composition (such as a granular composition or a composition packed in a water-soluble bag) in soil or an aqueous environment.
Pesticidal agents or compound referred to herein using their common name are known, for example, from “The Pesticide Manual”, 15th Ed., British Crop Protection Council 2009.
The term “beneficial” arthropod or insect as used herein refers to any arthropod or insect which has at least one life stage which has a negative impact on arthropod or insect agricultural pests and/or which pollinate crop plants. The term specifically includes arthropods classed as so-called parasitoids due to their tendency to lay eggs on or in an arthropod host. Thus beneficials include pollinators, parasitoids and predators, examples include but are not limited to: Cryptolaemus montrouzieri, Encarsia formosa,Eretmocerus eremicus, Eretmocerus mundus, Feltiella acarisuga Macrophus pygmeus, Nesidiocoris tenuis, aphid midge, centipedes, ground beetles such as Pterostichus melanarius, Agonum dorsale, and Nebria brevicollis, lady beetles such as Adalia bipunctata and Coccinella septempunctata, lacewings such as Chrysoperia carnea, hoverflies such as Syrphus spp., Phytoseiulus persimilis, pirate bugs such as Orius insidiosus, Orius laevigatus, Orius majusculus, predatory mites such as Amblydromalus limonicus, Amblyseius andersoni, Amblyseius barkeri, Amblyseius californicus, Amblyseius cucumeris, Amblyseius montdorensis, Amblyseius swirskii, Phytoseiulus persimilis, predatory midges such as Aphidoletes aphidimyza, rove beetle, tachnid flies, and wasps such as Dacnusa sibirica, Diglyphus isaea Trichogramma brassicae as well as ichneumonid wasps, chalcid wasps and braconid wasps such as Aphidius colemani, Aphidius ervi, Aphidius matrcariae.
The term “locus” as used herein means fields in or on which plants are growing, or where seeds of cultivated plants are sown, or where seed will be placed into the soil. It includes soil, seeds, and seedlings, as well as established vegetation.
The term “plants” refers to all physical parts of a plant, including seeds, seedlings, saplings, roots, tubers, stems, stalks, foliage, and fruits.
The methods of the invention are particularly applicable to the control of neonicotinoid resistant insects (and neonicotinoid resistance in insects) of the order Hemiptera, such as: Acyrthosiphum pisum, Aphis citricola, Aphis craccivora, Aphis fabae, Aphis frangulae, Aphis glycines, Aphis gossypii, Aphis nasturtii, Aphis pomi, Aphis spiraecola, Aulacorthum solani, Brachycaudus helichrysi, Brevicoryne brassicae, Diuraphis noxia, Dysaphis devecta, Dysaphis plantaginea, Eriosoma lanigerum, Hyalopterus pruni, Lipaphis erysimi, Macrosiphum avenae, Macrosiphum euphorbiae, Macrosiphum rosae, Myzus cerasi F., Myzus nicotianae, Myzus persicae, Nasonovia ribisnigri, Pemphigus bursarius, Phorodon humuli, Rhopalosiphum insertum Wa, Rhopalosiphum maidis Fitch, Rhopalosiphum padi L., Schizaphis graminum Rond., Sitobion avenae, Toxoptera aurantii, Toxoptera citricola, Phylloxera vitifoliae, Acyrthosiphon dirhodum, Acyrthosiphon solani, Aphis forbesi, Aphis grossulariae, Aphis idaei, Aphis illinoisensis, Aphis maidiradicis, Aphis ruborum, Aphis schneideri, Brachycaudus persicaecola, Cavariella aegopodii Scop., Cryptomyzus galeopsidis, Cryptomyzus ribis, Hyadaphis pseudobrassicae, Hyalopterus amygdali, Hyperomyzus pallidus, Macrosiphoniella sanborni, Metopolophium dirhodum, Myzus malisuctus, Myzus varians, Neotoxoptera sp, Nippolachnus piri Mats., Oregma lanigera Zehnter, Rhopalosiphum fitchii Sand., Rhopalosiphum nymphaeae, Rhopalosiphum sacchari Ze, Sappaphis piricola Okam.+T, Schizaphis piricola, Toxoptera theobromae Sch, and Phylloxera coccinea, Aleurodicus dispersus, Aleurocanthus spiniferus, Aleurocanthus woglumi, Aleurodicus cocois, Aleurodicus destructor, Aleurolobus barodensis, Aleurothrixus floccosus, Bemisia tabaci, Bemisia argentifolli, Dialeurodes citri, Dialeurodes citrifolli, Parabemisia myricae, Trialeurodes packardi, Trialeurodes ricini, Trialeurodes vaporariorum, Trialeurodes variabilis, Agonoscena targionii, Bactericera cockerelli, Cacopsylla pyri, Cacopsylla pyricola, Cacopsylla pyrisuga, Diaphorina citri, Glycaspis brimblecombei, Paratrioza cockerelli, Troza erytreae, Amarasca biguttula biguttula, Amritodus atkinsoni, Cicadella viridis, Cicadulina mbila, Cofana spectra, Dalbulus maidis, Empoasca decedens, Empoasca biguttula, Empoasca fabae, Empoasca vitis, Empoasca papaya, Idioscopus clypealis, Jacobiasca lybica, Laodelphax striatellus, Myndus crudus, Nephotettix virescens, Nephotettix cincticeps, Nilaparvata lugens, Peregrinus maidis, Perkinsiella saccharicida, Perkinsiella vastatrix, Recilia dorsalis, Sogatella furcifera, Tarophagus Proserpina, Zygina flammigera, Acanthocoris scabrator, Adelphocoris lineolatus, Amblypelta nitida, Bathycoelia thalassina, Blissus leucopterus, Clavigralla tomentosicollis, Edessa meditabunda, Eurydema pulchrum, Eurydema rugosum, Eurygaster Maura, Euschistus servus, Euschistus tristigmus, Euschistus heros Helopeltis antonii, Horcias nobilellus, Leptocorisa acuta, Lygus lineolaris, Lygus hesperus, Murgantia histrionic, Nesidiocoris tenuis, Nezara viridula, Oebalus insularis, Scotinophara coarctata,

Since the methods of the invention have the effect of controlling insect pest and or viral infestation in crops of useful plants, said methods may also be viewed as methods of improving and/or maintaining plant health in said crops or as methods of increasing/maintaining the well-being of a crop.
Crops of useful plants in which the composition according to the invention can be used include perennial and annual crops, such as berry plants for example blackberries, blueberries, cranberries, raspberries and strawberries; cereals for example barley, maize (corn), millet, oats, rice, rye, sorghum triticale and wheat; fibre plants for example cotton, flax, hemp and jute; field crops for example sugar and fodder beet, coffee, hops, mustard, oilseed rape (canola), poppy, sugar cane, sunflower, tea and tobacco; fruit trees for example apple, apricot, avocado, banana, cherry, citrus, nectarine, peach, pear and plum; grasses for example Bermuda grass, bluegrass, bentgrass, centipede grass, fescue, ryegrass, St. Augustine grass and Zoysia grass; herbs such as basil, borage, chives, coriander, lavender, lovage, mint, oregano, parsley, rosemary, sage and thyme; legumes for example beans, lentils, peas and soya beans; nuts for example almond, cashew, ground nut, hazelnut, peanut, pecan, pistachio and walnut; palms for example oil palm; ornamentals for example flowers, shrubs and trees; other trees, for example cacao, coconut, olive and rubber; vegetables for example asparagus, aubergine, broccoli, cabbage, carrot, cucumber, garlic, lettuce, marrow, melon, okra, onion, pepper, potato, pumpkin, rhubarb, spinach and tomato; and vines for example grapes.
Crops are to be understood as being those which are naturally occurring, obtained by conventional methods of breeding, or obtained by genetic engineering. They include crops which contain so-called output traits (e.g. improved storage stability, higher nutritional value and improved flavour).
Crops are to be understood as also including those crops which have been rendered tolerant to herbicides like bromoxynil or classes of herbicides such as ALS-, EPSPS-, GS-, HPPD- and PPO-inhibitors. An example of a crop that has been rendered tolerant to imidazolinones, e.g. imazamox, by conventional methods of breeding is Clearfield® summer canola. Examples of crops that have been rendered tolerant to herbicides by genetic engineering methods include e.g. glyphosate- and glufosinate-resistant maize varieties commercially available under the trade names RoundupReady®, Herculex I® and LibertyLink®.
Crops are also to be understood as being those which naturally are or have been rendered resistant to harmful insects. This includes plants transformed by the use of recombinant DNA techniques, for example, to be capable of synthesising one or more selectively acting toxins, such as are known, for example, from toxin-producing bacteria, especially those of the genus Bacillus. Further examples of toxins which can be expressed include δ-endotoxins, vegetative insecticidal proteins (Vip), insecticidal proteins of bacteria colonising nematodes, and toxins produced by scorpions, arachnids, wasps and fungi.
Example crops include: YieldGard® (maize variety that expresses a Cry1A(b) toxin); YieldGard Rootworm® (maize variety that expresses a CryIIIB(b1) toxin); YieldGard Plus® (maize variety that expresses a Cry1A(b) and a CryIIIB(b1) toxin); Starlink® (maize variety that expresses a Cry9(c) toxin); Herculex I® (maize variety that expresses a CryIF(a2) toxin and the enzyme phosphinothricine N-acetyltransferase (PAT) to achieve tolerance to the herbicide glufosinate ammonium); NuCOTN 33B® (cotton variety that expresses a Cry1A(c) toxin); Bollgard I® (cotton variety that expresses a Cry1A(c) toxin); Bollgard II® (cotton variety that expresses a Cry1A(c) and a CryIIA(b) toxin); VIPCOT® (cotton variety that expresses a VIP toxin); NewLeaf® (potato variety that expresses a CryIIIA toxin); Nature-Gard® Agrisure® GT Advantage (GA21 glyphosate-tolerant trait), Agrisure® CB Advantage (Bt11 corn borer (CB) trait), Agrisure® RW (corn rootworm trait) and Protecta®.
An example of a crop that has been modified to express the Bacillus thuringiensis toxin is the Bt maize KnockOut® (Syngenta Seeds). An example of a crop comprising more than one gene that codes for insecticidal resistance and thus expresses more than one toxin is VipCot® (Syngenta Seeds). Crops or seed material thereof can also be resistant to multiple types of pests (so-called stacked transgenic events when created by genetic modification). For example, a plant can have the ability to express an insecticidal protein while at the same time being herbicide tolerant, for example Herculex I® (Dow AgroSciences, Pioneer Hi-Bred International).
Crops are to be understood as including also crop plants which have been so transformed by the use of recombinant DNA techniques that they are capable of synthesising antipathogenic substances having a selective action, such as, for example, the so-called “pathogenesis-related proteins” (PRPs, see e.g. EP-A-0 392 225). Examples of such antipathogenic substances and transgenic plants capable of synthesising such antipathogenic substances are known, for example, from EP-A-0 392 225, WO 95/33818, and EP-A-0 353 191. The methods of producing such transgenic plants are generally known to the person skilled in the art and are described, for example, in the publications mentioned above.
Antipathogenic substances which can be expressed by such transgenic plants include, for example, ion channel blockers, such as blockers for sodium and calcium channels, for example the viral KP1, KP4 or KP6 toxins; stilbene synthases; bibenzyl synthases; chitinases; glucanases; the so-called “pathogenesis-related proteins” (PRPs; see e.g. EP-A-0 392 225); antipathogenic substances produced by microorganisms, for example peptide antibiotics or heterocyclic antibiotics (see e.g. WO 95/33818) or protein or polypeptide factors involved in plant pathogen defence (so-called “plant disease resistance genes”, as described in WO 03/000906).
The term “plant propagation material” is understood to denote generative parts of the plant, such as seeds, which can be used for the multiplication of the latter, and vegetative material, such as cuttings or tubers, for example potatoes. There may be mentioned for example seeds (in the strict sense), roots, fruits, tubers, bulbs, rhizomes and parts of plants. Germinated plants and young plants which are to be transplanted after germination or after emergence from the soil, may also be mentioned. These young plants may be protected before transplantation by a total or partial treatment by immersion. Preferably “plant propagation material” is understood to denote seeds.
The term “plant” or “useful plants” as used herein includes seedlings, bushes and trees. The term “crops” is to be understood as including also crop plants which have been so transformed by the use of recombinant DNA techniques that they are capable of synthesising one or more selectively acting toxins, such as are known, for example, from toxin-producing bacteria, especially those of the genus Bacillus.
Toxins that can be expressed by such transgenic plants include, for example, insecticidal proteins, from Bacillus cereus or Bacillus popilliae; or insecticidal proteins from
Bacillus thuringiensis, such as δ-endotoxins, e.g. Cry1Ab, Cry1Ac, Cry1F, Cry1Fa2, Cry2Ab, Cry3A, Cry3Bb1 or Cry9C, or vegetative insecticidal proteins (Vip), e.g. Vip1, Vip2, Vip3 or Vip3A; or insecticidal proteins of bacteria colonising nematodes, for example Photorhabdus spp. or Xenorhabdus spp., such as Photorhabdus luminescens, Xenorhabdus nematophilus; toxins produced by animals, such as scorpion toxins, arachnid toxins, wasp toxins and other insect-specific neurotoxins; toxins produced by fungi, such as Streptomycetes toxins, plant lectins, such as pea lectins, barley lectins or snowdrop lectins; agglutinins; proteinase inhibitors, such as trypsin inhibitors, serine protease inhibitors, patatin, cystatin, papain inhibitors; ribosome-inactivating proteins (RIP), such as ricin, maize-RIP, abrin, luffin, saporin or bryodin; steroid metabolism enzymes, such as 3-hydroxysteroidoxidase, ecdysteroid-UDP-glycosyl-transferase, cholesterol oxidases, ecdysone inhibitors, HMG-COA-reductase, ion channel blockers, such as blockers of sodium or calcium channels, juvenile hormone esterase, diuretic hormone receptors, stilbene synthase, bibenzyl synthase, chitinases and glucanases.
In the context of the present invention there are to be understood by δ-endotoxins, for example Cry1Ab, Cry1Ac, CryI F, Cry1Fa2, Cry2Ab, Cry3A, Cry3Bb1 or Cry9C, or vegetative insecticidal proteins (Vip), for example Vip1, Vip2, Vip3 or Vip3A, expressly also hybrid toxins, truncated toxins and modified toxins. Hybrid toxins are produced recombinantly by a new combination of different domains of those proteins (see, for example, WO 02/15701). Truncated toxins, for example a truncated Cry1Ab, are known. In the case of modified toxins, one or more amino acids of the naturally occurring toxin are replaced. In such amino acid replacements, preferably non-naturally present protease recognition sequences are inserted into the toxin, such as, for example, in the case of Cry3A055, a cathepsin-G-recognition sequence is inserted into a Cry3A toxin (see WO 03/018810).
Examples of such toxins or transgenic plants capable of synthesising such toxins are disclosed, for example, in EP-A-0 374 753, WO 93/07278, WO 95/34656, EP-A-0 427 529, EP-A-451 878 and WO 03/052073.
The processes for the preparation of such transgenic plants are generally known to the person skilled in the art and are described, for example, in the publications mentioned above. CryI-type deoxyribonucleic acids and their preparation are known, for example, from WO 95/34656, EP-A-0 367 474, EP-A-0 401 979 and WO 90/13651.
The toxin contained in the transgenic plants imparts to the plants tolerance to harmful insects. Such insects can occur in any taxonomic group of insects, but are especially commonly found in the beetles (Coleoptera), two-winged insects (Diptera) and butterflies (Lepidoptera).
Transgenic plants containing one or more genes that code for an insecticidal resistance and express one or more toxins are known and some of them are commercially available. Examples of such plants are: YieldGard® (maize variety that expresses a Cry1Ab toxin); YieldGard Rootworm® (maize variety that expresses a Cry3Bb1 toxin); YieldGard Plus® (maize variety that expresses a Cry1Ab and a Cry3Bb1 toxin); Starlink® (maize variety that expresses a Cry9C toxin); Herculex I® (maize variety that expresses a
CryI Fa2 toxin and the enzyme phosphinothricine N-acetyltransferase (PAT) to achieve tolerance to the herbicide glufosinate ammonium); NuCOTN 33B® (cotton variety that expresses a Cry1Ac toxin); Bollgard I® (cotton variety that expresses a Cry1Ac toxin); Bollgard II® (cotton variety that expresses a Cry1Ac and a Cry2Ab toxin); VipCot® (cotton variety that expresses a Vip3A and a Cry1Ab toxin); NewLeaf® (potato variety that expresses a Cry3A toxin); NatureGard®, Agrisure® GT Advantage (GA21 glyphosate-tolerant trait), Agrisure® CB Advantage (Bt11 corn borer (CB) trait) and Protecta®.

Transgenic crops of insect-resistant plants are also described in BATS (Zentrum fur Biosicherheit and Nachhaltigkeit, Zentrum BATS, Clarastrasse 13, 4058 Basel, Switzerland) Report 2003, (http://bats.ch).
Crops are also to be understood as being those which have been rendered resistant to harmful insects by genetic engineering methods, for example Bt maize (resistant to European corn borer), Bt cotton (resistant to cotton boll weevil) and also Bt potatoes (resistant to Colorado beetle). Examples of Bt maize are the Bt 176 maize hybrids of NK® (Syngenta Seeds). Examples of transgenic plants comprising one or more genes that code for an insecticidal resistance and express one or more toxins are KnockOut® (maize), Yield Gard® (maize), NuCOTIN33B® (cotton), Bollgard® (cotton), NewLeaf® (potatoes), NatureGard® and Protexcta®.
Plant crops or seed material thereof can be both resistant to herbicides and, at the same time, resistant to insect feeding (“stacked” transgenic events). For example, seed can have the ability to express an insecticidal Cry3 protein while at the same time being tolerant to glyphosate.
Crops are also to be understood as being those which are obtained by conventional methods of breeding or genetic engineering and contain so-called output traits (e.g. improved storage stability, higher nutritional value and improved flavour).

Accordingly, as used herein, part of a plant includes propagation material. There may be mentioned, e.g., the seeds (in the strict sense), roots, fruits, tubers, bulbs, rhizomes, parts of plants. Germinated plants and young plants, which are to be transplanted after germination or after emergence from the soil, may also be mentioned. These young plants may be protected before transplantation by a total or partial treatment by immersion.
Parts of plant and plant organs that grow at later point in time are any sections of a plant that develop from a plant propagation material, such as a seed. Parts of plant, plant organs, and plants can also benefit from the pest damage protection achieved by the application of the compound on to the plant propagation material. In an embodiment, certain parts of a plant and certain plant organs that grow at later point in time can also be considered as plant propagation material, which can themselves be applied (or treated) with the compound; and consequently, the plant, further parts of the plant and further plant organs that develop from the treated parts of plant and treated plant organs can also benefit from the pest damage protection achieved by the application of the compound on to the certain parts of plant and certain plant organs.
Methods for applying or treating pesticidal active ingredients on to plant propagation material, especially seeds, are known in the art, and include dressing, coating, pelleting and soaking application methods of the propagation material. It is preferred that the plant propagation material is a seed.
Although it is believed that the present method can be applied to a seed in any physiological state, it is preferred that the seed be in a sufficiently durable state that it incurs no damage during the treatment process. Typically, the seed would be a seed that had been harvested from the field; removed from the plant; and separated from any cob, stalk, outer husk, and surrounding pulp or other non-seed plant material. The seed would preferably also be biologically stable to the extent that the treatment would cause no biological damage to the seed. It is believed that the treatment can be applied to the seed at any time between harvest of the seed and sowing of the seed or during the sowing process (seed directed applications). The seed may also be primed either before or after the treatment.
Even distribution of the compound and adherence thereof to the seeds is desired during propagation material treatment. Treatment could vary from a thin film (dressing) of a formulation containing the compound, for example, a mixture of active ingredient(s), on a plant propagation material, such as a seed, where the original size and/or shape are recognizable to an intermediary state (such as a coating) and then to a thicker film (such as pelleting with many layers of different materials (such as carriers, for example, clays; different formulations, such as of other active ingredients; polymers; and colourants) where the original shape and/or size of the seed is no longer recognisable into the controlled release material or applied between layers of materials, or both.
The seed treatment occurs to an unsown seed, and the term “unsown seed” is meant to include seed at any period between the harvest of the seed and the sowing of the seed in the ground for the purpose of germination and growth of the plant.
Treatment to an unsown seed is not meant to include those practices in which the active ingredient is applied to the soil but would include any application practice that would target the seed during the planting process.
Preferably, the treatment occurs before sowing of the seed so that the sown seed has been pre-treated with the compound. In particular, seed coating or seed pelleting are preferred in the treatment of the compound. As a result of the treatment, the compound is adhered on to the seed and therefore available for pest control.
The treated seeds can be stored, handled, sowed and tilled in the same manner as any other active ingredient treated seed.
The compounds of formula (I) may exist in different geometric or optical isomers or tautomeric forms. This invention covers all such isomers and tautomers and mixtures thereof in all proportions as well as isotopic forms such as deuterated compounds. The invention also covers salts and N-oxides.
The compounds of the invention may contain one or more asymmetric carbon atoms, and may exist as enantiomers (or as pairs of diastereoisomers) or as mixtures of such.

The cycloalkyl groups are preferably C3-C8, more preferably C3-C6 cycloalkyl groups. Where a cycloalkyl moiety is said to be substituted, the cycloalkyl moiety is preferably substituted by one to four substituents, most preferably by one to three substituents.
Aryl groups (either alone or as part of a larger group, such as aryloxy) are aromatic ring systems which can be in mono-, bi- or tricyclic form. Examples of such rings include phenyl, naphthyl, anthracenyl, indenyl or phenanthrenyl. Preferred aryl groups are phenyl and naphthyl, phenyl being most preferred.

Further suitable phosphates are tris-esters of phosphoric acid with aliphatic or aromatic alcohols and/or bis-esters of alkyl phosphonic acids with aliphatic or aromatic alcohols, which are a high performance oil-type adjuvant. These tris-esters have been described, for example, in WO0147356, WO0056146, EP-A-0579052 or EP-A-1018299 or are commercially available under their chemical name.

For example, the oil additive can be added to the spray tank in the desired concentration after the spray mixture has been prepared. Preferred oil additives comprise mineral oils or an oil of vegetable origin, for example rapeseed oil such as ADIGOR® and MERO®, olive oil or sunflower oil, emulsified vegetable oil, such as AMIGO® (Rhône-Poulenc Canada Inc.), alkyl esters of oils of vegetable origin, for example the methyl derivatives, or an oil of animal origin, such as fish oil or beef tallow. A preferred additive contains, for example, as active components essentially 80% by weight alkyl esters of fish oils and 15% by weight methylated rapeseed oil, and also 5% by weight of customary emulsifiers and pH modifiers. Especially preferred oil additives comprise alkyl esters of C8-C22 fatty acids, especially the methyl derivatives of C12-C18 fatty acids, for example the methyl esters of lauric acid, palmitic acid and oleic acid, being important. Those esters are known as methyl laurate (CAS-111-82-0), methyl palmitate (CAS-112-39-0) and methyl oleate (CAS-112-62-9). A preferred fatty acid methyl ester derivative is Emery® 2230 and 2231 (Cognis GmbH). Those and other oil derivatives are also known from the Compendium of Herbicide Adjuvants, 5th Edition, Southern Illinois University, 2000. Also, alkoxylated fatty acids can be used as additives in the inventive compositions as well as polymethylsiloxane based additives, which have been described in WO08/037373.

Such additives include surface active agents, spray additives based on oils, for example certain mineral oils or natural plant oils (such as soy bean and rape seed oil), and blends of these with other bio-enhancing adjuvants (ingredients which may aid or modify the action of a compound of formula (I)).
Preferred compositions for use in methods of the invention are composed in particular of the following constituents (throughout, percentages are by weight):
Emulsifiable concentrates (EC):
A compound of formula I may be applied to a neonicotinoid resistant insect or crop of useful plants using any standard application method with which the skilled man is familiar, such as foliar spay or treatment of the plant propagation materials of the crop. Similarly, for methods of controlling insect resistance, neonicotinoid insecticides may be applied to an insect/crop/plant propagation material of useful plants using any known method of application. Further guidance may be found in the art, which includes for example, advice on application given on the labels of commercially available products.
In another aspect of the invention, the neonicotinoid insecticide is applied to the plant propagation material (such as seeds, young plants, transplants etc.) of the respective crops followed by the foliar application of a compound of the formula (I) starting in the 3-to 5-leaf up to the fruit setting crop stage. It has been found, that beginning with the 3- to 5-leaf crop stage, when the level of insect control by the neonicotinoid insecticide starts to decrease, another boost in insect control can be achieved by the foliar application of a compound of the formula (I), which, surprisingly, is accompanied by pronounced crop enhancement effects such as an increase in the formation of fine roots, synchronisation of flowering, drought resistance and, in particular, an increase in yield.
Examples of typical formulations are provided below (throughout, percentages are by weight)
These solutions are suitable for application in the form of micro-drops.

A compound of formula (I) may be applied by any of the known means of applying pesticidal compounds. For example, it may be applied, formulated or unformulated, to the pests or to a locus of the pests (such as a habitat of the pests, or a growing plant liable to infestation by the pests) or to any part of the plant, including the foliage, stems, branches or roots, to the seed before it is planted or to other media in which plants are growing or are to be planted (such as soil surrounding the roots, the soil generally, paddy water or hydroponic culture systems), directly or it may be sprayed on, dusted on, applied by dipping, applied as a cream or paste formulation, applied as a vapor or applied through distribution or incorporation of a composition (such as a granular composition or a composition packed in a water-soluble bag) in soil or an aqueous environment.
A compound of formula (I) may also be injected into plants or sprayed onto vegetation using electrodynamic spraying techniques or other low volume methods, or applied by land or aerial irrigation systems.
Compositions for use as aqueous preparations (aqueous solutions or dispersions) are generally supplied in the form of a concentrate containing a high proportion of the active ingredient, the concentrate being added to water before use. These concentrates, which may include DCs, SCs, ECs, EWs, MEs, SGs, SPs, WPs, WGs and CSs, are often required to withstand storage for prolonged periods and, after such storage, to be capable of addition to water to form aqueous preparations which remain homogeneous for a sufficient time to enable them to be applied by conventional spray equipment. Such aqueous preparations may contain varying amounts of a compound of formula (I) (for example 0.0001 to 10%, by weight) depending upon the purpose for which they are to be used.
A compound of formula (I) may be used in mixtures with fertilizers (for example nitrogen-, potassium- or phosphorus-containing fertilizers). Suitable formulation types include granules of fertilizer. The mixtures preferably contain up to 25% by weight of the compound of formula (I).
The invention therefore also provides a fertilizer composition comprising a fertilizer and a compound of formula (I).
The compositions of this invention may contain other compounds having biological activity, for example micronutrients or compounds having fungicidal activity or which possess plant growth regulating, herbicidal, insecticidal, nematicidal or acaricidal activity.
The compound of formula (I) may be the sole active ingredient of the composition or it may be admixed with one or more additional active ingredients such as a pesticide, e.g. a insecticide, fungicide or herbicide, or a synergist or plant growth regulator where appropriate. An additional active ingredient may provide a composition having a broader spectrum of activity or increased persistence at a locus; synergize the activity or complement the activity (for example by increasing the speed of effect or overcoming repellency) of the compound of formula (I); or help to overcome or prevent the development of resistance to individual components.

The active ingredient mixture of the compounds of formula I selected from Tables 1 and 2 (above) with active ingredients described above comprises a compound selected from Tables 1 and 2 (above) and an active ingredient as described above preferably in a mixing ratio of from 100:1 to 1:6000, especially from 50:1 to 1:50, more especially in a ratio of from 20:1 to 1:20, even more especially from 10:1 to 1:10, very especially from 5:1 and 1:5, special preference being given to a ratio of from 2:1 to 1:2, and a ratio of from 4:1 to 2:1 being likewise preferred, above all in a ratio of 1:1, or 5:1, or 5:2, or 5:3, or 5:4, or 4:1, or 4:2, or 4:3, or 3:1, or 3:2, or 2:1, or 1:5, or 2:5, or 3:5, or 4:5, or 1:4, or 2:4, or 3:4, or 1:3, or 2:3, or 1:2, or 1:600, or 1:300, or 1:150, or 1:35, or 2:35, or 4:35, or 1:75, or 2:75, or 4:75, or 1:6000, or 1:3000, or 1:1500, or 1:350, or 2:350, or 4:350, or 1:750, or 2:750, or 4:750. Those mixing ratios are by weight.
The mixtures as described above can be used in a method for controlling pests, which comprises applying a composition comprising a mixture as described above to the pests or their environment, with the exception of a method for treatment of the human or animal body by surgery or therapy and diagnostic methods practised on the human or animal body.
The mixtures comprising a compound of formula I selected from Tables 1 and 2 (above) and one or more active ingredients as described above can be applied, for example, in a single “ready-mix” form, in a combined spray mixture composed from separate formulations of the single active ingredient components, such as a “tank-mix”, and in a combined use of the single active ingredients when applied in a sequential manner, i.e. one after the other with a reasonably short period, such as a few hours or days. The order of applying the compounds of formula I selected from Tables 1 and 2 (above) and the active ingredients as described above is not essential for working the present invention.
The compositions according to the invention can also comprise further solid or liquid auxiliaries, such as stabilizers, for example unepoxidized or epoxidized vegetable oils (for example epoxidized coconut oil, rapeseed oil or soya oil), antifoams, for example silicone oil, preservatives, viscosity regulators, binders and/or tackifiers, fertilizers or other active ingredients for achieving specific effects, for example bactericides, fungicides, nematocides, plant activators, molluscicides or herbicides.
The compositions according to the invention are prepared in a manner known per se, in the absence of auxiliaries for example by grinding, screening and/or compressing a solid active ingredient and in the presence of at least one auxiliary for example by intimately mixing and/or grinding the active ingredient with the auxiliary (auxiliaries). These processes for the preparation of the compositions and the use of the compounds I for the preparation of these compositions are also a subject of the invention.
The application methods for the compositions, that is the methods of controlling pests of the abovementioned type, such as spraying, atomizing, dusting, brushing on, dressing, scattering or pouring - which are to be selected to suit the intended aims of the prevailing circumstances - and the use of the compositions for controlling pests of the abovementioned type are other subjects of the invention. Typical rates of concentration are between 0.1 and 1000 ppm, preferably between 0.1 and 500 ppm, of active ingredient. The rate of application per hectare is preferably 1 to 2000 g of active ingredient per hectare, more preferably 10 to 1000 g/ha, most preferably 10 to 600 g/ha.
A preferred method of application in the field of crop protection is application to the foliage of the plants (foliar application), it being possible to select frequency and rate of application to match the danger of infestation with the pest in question. Alternatively, the active ingredient can reach the plants via the root system (systemic action), by drenching the locus of the plants with a liquid composition or by incorporating the active ingredient in solid form into the locus of the plants, for example into the soil, for example in the form of granules (soil application). In the case of paddy rice crops, such granules can be metered into the flooded paddy-field.
The compounds of the invention and compositions thereof are also be suitable for the protection of plant propagation material, for example seeds, such as fruit, tubers or kernels, or nursery plants, against pests of the abovementioned type. The propagation material can be treated with the compound prior to planting, for example seed can be treated prior to sowing. Alternatively, the compound can be applied to seed kernels (coating), either by soaking the kernels in a liquid composition or by applying a layer of a solid composition. It is also possible to apply the compositions when the propagation material is planted to the site of application, for example into the seed furrow during drilling. These treatment methods for plant propagation material and the plant propagation material thus treated are further subjects of the invention. Typical treatment rates would depend on the plant and pest/fungi to be controlled and are generally between 1 to 200 grams per 100 kg of seeds, preferably between 5 to 150 grams per 100 kg of seeds, such as between 10 to 100 grams per 100 kg of seeds.
The term seed embraces seeds and plant propagules of all kinds including but not limited to true seeds, seed pieces, suckers, corns, bulbs, fruit, tubers, grains, rhizomes, cuttings, cut shoots and the like and means in a preferred embodiment true seeds.
The present invention also comprises seeds coated or treated with or containing a compound of formula I. The term “coated or treated with and/or containing” generally signifies that the active ingredient is for the most part on the surface of the seed at the time of application, although a greater or lesser part of the ingredient may penetrate into the seed material, depending on the method of application. When the said seed product is (re)planted, it may absorb the active ingredient. In an embodiment, the present invention makes available a plant propagation material adhered thereto with a compound of formula (I). Further, it is hereby made available, a composition comprising a plant propagation material treated with a compound of formula (I).
Seed treatment comprises all suitable seed treatment techniques known in the art, such as seed dressing, seed coating, seed dusting, seed soaking and seed pelleting. The seed treatment application of the compound formula (I) can be carried out by any known methods, such as spraying or by dusting the seeds before sowing or during the sowing/planting of the seeds.
Some mixtures may comprise active ingredients which have significantly different physical, chemical or biological properties such that they do not easily lend themselves to the same conventional formulation type. In these circumstances other formulation types may be prepared. For example, where one active ingredient is a water insoluble solid and the other a water insoluble liquid, it may nevertheless be possible to disperse each active ingredient in the same continuous aqueous phase by dispersing the solid active ingredient as a suspension (using a preparation analogous to that of an SC) but dispersing the liquid active ingredient as an emulsion (using a preparation analogous to that of an EW). The resultant composition is a suspoemulsion (SE) formulation.

The level of resistance and therefore the impact on the performance of the insecticide can be measured by the use of a ‘Resistance Factor’. The resistance factor can be calculated by dividing the concentration of an insecticide that provides a set level of mortality (i.e. 80%) for the ‘resistant’ strain with the concentration of the same insecticide that provides the same level of mortality for the ‘susceptible’ insect of the same species and life-stage. Although there are no set rules, a low value (less than or equal to 20) indicates no cross-resistance and only natural levels of variation and a high value (greater than or equal to 64) provides strong evidence of cross-resistance.
In order to obtain neonicotinoid resistant insects, a researcher is to locate a host crop and geographical region where the relevant resistance had been reported in literature (e.g. Myzus persicae—peach orchards of France. Bemisia tabaci—protected vegetables in Spain). Live samples of the insect are then collected from the locations/host crops and transported back to a laboratory, where breeding colonies would be established. Non-resistant individuals with the colonies are eliminated to provide a homologous-resistant population. This is achieved by either establishing a clonal population of insects from a single resistant individual (e.g. Myzus persicae) or by repeatedly exposing the colony to a dose of insecticide which kills susceptible insects, whilst leaving resistant insects unaffected. The resistant phenotype of the insect colony is determined either by conducting a full dose response bioassay (examples of which can be found on the IRAC web-site and below) with a neonicotinoid insecticide and comparing the bioassay results to similar bioassay results for a known susceptible colony of the same species. Alternatively the resistance genotype of the individual insects can be determined by molecular techniques (e.g. PCR) if the resistance mechanism for the relevant species is known.
a) Neonicotinoid resistant strain of the green peach aphid (Myzus persicae)
a.1) Myzus persicae strains utilised:
a2) Bioassay methods utilised
a.2.1) Bioassay, method A:
Myzus persicae: mixed population, contact activity, curative on pea seedlings
Pea seedlings were infested with an aphid population of mixed ages and treated with the test solutions in a spray chamber. 6 days after treatment samples were checked for mortality.
Application rates: 200 ppm, 50 ppm, 12.5 ppm, 3 ppm and 0.8 ppm.
a.2.2) Dose-response bioassay, method B:
Test pots (45 mm diameter) were prepared with discs of Chinese cabbage on tap water agar adapted from Herron et al (Aust J Entomol 37:70-73 (1998)). Mixed age aphids (numbering 20-30) were transferred to the dishes and allowed to settle for 24 h at 21 degrees C. with a 16:8 h light/dark regime. Dead individuals were removed prior to application. Serial dilutions of insecticide were applied using a Potter precision laboratory spray tower (Burkard Scientific, Uxbridge, UK), before sealing each pot with a lid. Each treatment replicate was sprayed with 3 mL solution at 0.6 bar with a 3 s settling time (equivalent to approximately 400 L ha-1). A minimum of five insecticide concentrations and three replicates per treatment were utilised in each test. Aphid mortality is assessed at 72 hours after treatment (depending on insecticide mode of action). LC50 values were calculated by LOGIT analysis (using ACSAPwin program).
a.3) Results
The following compounds, according to the present invention, gave at least 80% control of the FRC-P (Neonicotinoid resistant) strain of Myzus persicae at 200 ppm and exhibited a resistance factor of ≦20: 1.065, 1.067, 1.072, 1.073, 1.075, 1.076, 1.078, 1.079, 1.082, 1.084, 1.086, 1.087, 1.088, 1.093, 1.107, 1.108, 1.111, 1.112, 1.116, 1.125, 1.138, 2.065, 2.070, 2.071, 2.072, 2.074, 2.075, 2.088, 2.089, 2.109, 2.116, 2.118, and 2.127.
Thiacloprid and Imidacloprid failed to give 80% control of the FRC-P (Neonicotinoid resistant) strain of Myzus persicae at 200 ppm and both exhibited a Resistance Factor (RF80) of >64.
b) Neonicotinoid and pyrethroid resistant strain of the tobacco whitefly (Bemisia tabaci)

b.2) Bioassay methods utilised:
b.2.1) Bioassay, method A:
Bemisia tabaci: residual activity, preventive egg lay
Cotton seedlings, with all but a single leaf removed are treated with the diluted test solutions in a turn table spray chamber. 24 hours after drying, they are infested with 20 adult whitefly. 3 days after exposure, the total number of adult whitefly and the total number of whitefly eggs laid on the leaf are counted. Percentage control of egg lay is calculated and corrected for control mortality.
Application rates: 200 ppm, 50 ppm, 12.5 ppm, 3 ppm and 0.8 ppm.
b.2.2) Dose-response bioassay, method B:
Test pots (45 mm diameter) were prepared with discs of cotton leaf on tap water agar adapted from Herron et al (Aust J Entomol 37:70-73 (1998)). Serial dilutions of insecticide were applied using a Potter precision laboratory spray tower (Burkard Scientific, Uxbridge, UK). Each treatment replicate was sprayed with 3 mL solution at 0.6 bar with a 3 s settling time (equivalent to approximately 400 L ha-1). A minimum of five insecticide concentrations and three replicates per treatment were utilised in each test. After the test solutions had dried, adult whitefly (numbering 20-30) were transferred to the pots, before it was sealed with a lid and turned upside down (whitefly on underside of leaf surface) for 72 hours after treatment at 24 degrees C. with a 16:8 h light/dark regime. Whitefly mortality is evaluated and LC50 values were calculated by LOGIT analysis (using ACSAPwin program).

Test on Orius laevigatus
Phaseolus vulgaris var. Fulvio (french bean) plants were reduced to one leaf. With the leaves held in a horizontal position, a track sprayer was used to treat the plants at a rate corresponding to 2001/ha. Once dry, leaf discs were collected from the plants and placed treated side up in petri dishes containing 1% water agar.
A paper triangle was added for shelter, and a suitable amount of Ephestia eggs were added as a food supply. Five (5) Orius laevigatus (predatory bug, Syngenta Bioline) adults were added and the dishes closed with a cotton filter and perforated plastic lid. The dishes were incubated in a climate chamber at 25° C., 75% relative humidity, 16:8 h light/dark regime.
Six replicates were provided for each treatment and concentration level. The number of living and dead Orius laevigatus were counted two and four days after infestation (DAI). At the day two evaluation the food supply was replenished.
