The active compounds of the present invention are also useful for removing an arthropod, a worm and a plasmodium which attacks an animal. Examples of the animal include an agricultural animals such as a cow, a sheep, a goat, a horse, a pig, a donkey, a camel, a buffalo, a rabbit, a chicken, a turkey, a duck, a goose, a cultured fish, a honey bee, etc. In addition, a pet which is also called as a companion animal, for example, a dog, a cat, a caged bird, an aquarium fish, and a laboratory animal (e.g., a hamster, a guinea pig, a rat, a mouse and the like) are also included.
With control of the arthropod, larvae, and/or plasmodium by using the active compound of the present invention, death ratio of a host animal can be reduced and productivity (for meat, milk, wool, leather, egg, and honey) and health of the animal can be improved. As a result, it is intended to achieve economically more favorable and simple animal breeding.
For example, it is preferable that sucking of host blood by a parasite is either prevented or inhibited (if possible). Parasite removal can be useful for preventing infection which is caused by inflammatory pathogens.
The term “removal” that is used in the present specification regarding a veterinary medicine field means that the active compounds are effective for reducing the occurrence ratio of each parasite in the animal infected with it to a harmless level. More specifically, the term “removal” that is used in the present specification means that the active compounds are effective for destroying parasites, inhibiting growth or propagation thereof.
In the present invention, substances having pesticidal effects against harmful pests encompassing all of such pests are referred to as pesticides.
When used as pesticides, the active compounds of the present invention can be prepared in the form of a common preparation. Such preparation form may include, for example, liquids, emulsions, wettable powders, granulated wettable powders, suspensions, powders, foams, pastes, tablets, granules, aerosols, natural or synthetic agents impregnated with the active compounds, microcapsules, coating agents for seeds, formulations equipped with a combustion device (the combustion device can be a smoke or fog cartridge, a can or a coil, etc.) and ULV [cold mist, warm mist], and the like.
These preparations can be produced by known methods per se. For example, they can be prepared by mixing the active compounds with extenders, namely, liquid diluents or carriers; liquefied gas diluents or carriers; solid diluents or carriers and, optionally, with surfactants, namely, emulsifiers and/or dispersants and/or foam formers and the like.
In case of using water as an extender, for example, organic solvents can be used as auxiliary solvents.

Further, the active compounds of the Formula (I) of the present invention can be provided as mixtures with synergists. Such preparation and usage form may include those that are commercially useful. The synergists are not necessarily active by themselves. Rather, they are the compounds which enhance the activity of the active compounds.
The amount of the active compounds of the Formula (I) of the present invention in a commercially useful form may vary over a broad range.
The concentration of the active compounds of the Formula (I) of the present invention for actual use can be, for example, in the range from 0.0000001 to 95% by weight, preferably from 0.00001 to 90% by weight.
The compounds of the Formula (I) of the present invention can be used according to any common methods that are appropriate for a usage form.
The active compounds of the present invention have stability that is effective for alkaline substances present in lime materials when the compounds are used against hygienic pests and storage pests. In addition, they exhibit excellent residual effectiveness in woods and soils.
Generally, when the active compounds of the present invention are used for the treatment of animals, they can be directly applied to the animal. Preferably, the compounds are applied in the form of pharmaceutical composition which may include a vehicle, an auxiliary agent, or both, that are known in the art and pharmaceutically acceptable.

(NMR Table)
Unless other methods are mentioned specifically, the sample solution preparation was prepared as follows.
Solvent: 3 parts by weight of dimethyl formamide
Emulsifier: 1 part by weight of polyoxyethylene alkyl phenyl ether
To prepare a suitable concoction including the active compound, 1 part by weight of the active compound was mixed with the above amount of the solvent containing the above amount of the emulsifier, and the resulting mixture was diluted with water to predetermined concentrations.
(Test Method)
50 to 100 of adult Tetranychus urticae were inoculated to leaves at 2-leaf stage of Egyptian bean planted in pots of 6 cm in diameter, to which, 1 day later, the above prepared water diluted solution of the active compound at the predetermined concentration was sufficiently sprayed with a spray gun. After the compounds were sprayed, the pots were left in a greenhouse and the acaricidal ratio was calculated seven days later. 100% acaricidal ratio means death of all the mites, while 0% acaricidal ratio means none of the mites were dead.
(Test Result)
In the Biological Test Example 1 above, the following compounds as a representative example showed a pest-controlling efficacy of 100% acaricidal ratio at 100 ppm of an effective component concentration: Compound No. 1-17, 1-19, 5-17, 5-19, 5-20, 5-374-a and 5-375-a.
(Test Method)
Leaves of cucumbers were immersed in the water-diluted solution containing the active compound at the predetermined concentration which was prepared above and, after the solution was air-dried, the resultant leaves were put onto sterilized black soil in a plastic cup, into which five of the 2nd-instar larvae of Aulacophora femoralis were then released. The cup was covered with a lid and maintained in a temperature controlled room at 25° C. having humidity of 50 to 60%. Seven days later, the number of dead larvae was counted to calculate the pesticidal ratio. 100% pesticidal ratio means death of all the larvae, while 0% pesticidal ratio means no dead larvae.
(Test Result)
In the Biological Test Example 2 above, the following compounds as a representative example showed a pest-controlling efficacy of 100% pesticidal ratio at 100 ppm of an effective component concentration: Compound No. 1-17, 1-19, 3-17, 3-19, 3-20, 5-17, 5-19, 5-20, 5-374-a, 5-375-a and 7-19.
(Test Method)
Powdery artificial feeds (trade name: SILK MATE, manufactured by Nihon Nosan Kogyo, Japan, 2.3 g) were added to a plastic cup (diameter: 7.5 cm, height: 4 cm) to achieve a certain thickness. Water-diluted liquid (5 mL) of the active compound prepared above having predetermined concentration was evenly poured thereto and allowed to stand until the feeds are solidified. Five of the 3rd-instar larvae of Spodoptera litura were released in each cup, and covered with a lid. The cups were put in a temperature controlled room at 25° C. having humidity of 50 to 60%, and the number of dead larvae after 7 days was determined to calculate the pesticidal ratio. 100% pesticidal ratio means death of all the larvae, while 0% pesticidal ratio means no dead larvae.
