This invention relates to killing mosquitoes, and in particular to dual action lethal containers, systems and methods of use and novel, long-lasting compositions and formulas which are used to kill adult mosquitoes and their larvae.
Over the years, Ovitrap type containers, such as Ovitraps, have been used and deployed to control mosquitoes. See for example, U.S. Pat. No. 5,983,557 to Perich et al.; U.S. Pat. No. 6,185,861 to Perich; and U.S. Pat. No. 6,389,740 to Perich et al.; and Zeichner, Brian C. “The lethal ovitrap: a response to the resurgence of dengue and chikungunya”, U.S. Army Medical Journal, July-September 2011. These types of Ovitraps have generally used a paper strip having insecticide that hangs within a cup filled with water up to a series of drain holes. The insecticide strip will hang into the water, with the intention of killing female mosquitoes as they land on the Ovitrap to lay eggs. However, these types of Ovitraps have limitations due to the insecticide on the paper breaking down rapidly because of water contact, and also the trap is not designed to kill larvae.
For example, these traps have lacked the use of a timed release of insecticide, and the water ended up breaking down the insecticide to become ineffective or not killing fast enough to prevent egg laying because of insecticide resistance in the mosquito population. A study in Key West, Fla. that used thousands of Ovitraps ended up producing mosquitoes from these water filled containers. Additionally, the Ovitraps only used an adulticide which was not effective in killing mosquito larvae.
Thus, the need exists for solutions to the above problems with the prior art.
A primary objective of the present invention is to provide dual action lethal containers, systems and methods which are used to kill adult mosquitoes and their larvae.
A secondary objective of the present invention is to provide novel, long-lasting coatings, compositions and formulas that can be used to kill both adult mosquitoes and their larvae.
A third objective of the present invention is to provide dual action Ovitrap containers, systems and methods which kills both adult females, that seek the ovitrap as a location to lay eggs, as well as larvae, from any eggs that may be laid by the mosquito females before they are killed by the adulticide treatment.
A fourth objective of the present invention is to provide long lasting insecticidal coatings as container linings that can prevent quick degradation of insecticidal activity which occurs when insecticides are applied directly to surfaces of lethal ovitraps.
A fifth objective of the present invention is to provide for the use of slow release insecticide coatings as liners in containers so that pesticide exposure by humans is minimized when treated surfaces are accidentally contacted.
A sixth objective of the present invention is to provide for the use of slow release insecticide coatings as liners in containers which use different active ingredients for elimination of adults and larvae can delay development of pesticide resistance in mosquito populations and provide more efficient control of disease vectors.
A seventh objective of the present invention is to provide for the use of slow release insecticide coatings as liners in containers which can minimize environmental contamination, non-target exposure and chances of accidental insecticide poisoning to humans and animals.
The use of long-lasting insecticidal coating provides long-lasting control, as opposed to direct application of insecticides to internal surfaces of lethal ovitraps. The invention has the addition of larvicide to lethal ovitraps.
An additive can be added to the coating to enhance stability of the insecticide active ingredients and allows slow release of insecticide for a prolonged deployment of the trap in field situations.
Types of additives can include but are not limited to CARBONXIDE™ (a mixture of saturated and unsaturated hydrocarbons, and other compounds, which is an antioxidant that affects the microporosity of materials and prevents effects of aging), the additive of which is described in U.S. Pat. No. 5,401,310 to Ture, which is incorporated by reference in its' entirety. CARBONXIDE™ has been manufactured by Refrasud International s.r.l., a refractory innovation technology company, from Taranto, Italy. Other types of additives can include synergists, such as but not limited to Piperonyl butoxide (PBO), MGK-264, Etofenprox and Pyrethrins.
A synergist can be added to the long-lasting coating to overcome insecticide resistance in mosquito populations. The coating not only can protect the insecticidal active ingredient, but also synergists from degradation over time. Additionally, a combination of both an adulticide and a larvicide with a different mode of action in a single coating could allow for easier manufacturing.
The dual action ovitrap can be sold both in the retail market, for use by homeowners who need to eliminate mosquitoes from their property, and professional market, for use by mosquito control districts, pest control operators, the armed forces, humanitarian institutions and others involved in the control of mosquitoes in different situations.
The long-lasting insecticide coatings can be marketed for other uses where insect control is desired. Such coating could be used in external building walls, internal walls, and any other surfaces where mosquitoes and other pestiferous insects may rest and congregate.
The dual action lethal Ovitrap type containers can be used to kill mosquitoes and their larvae. The inside of a cup can be covered with insecticidal coating. The inner, upper surface can be coated with insecticide that kills adult mosquitoes as they land to lay eggs, and the inner lower surface can be coated with larvicide that kills larval mosquitoes that could emerge from eggs, or the interior of the trap can be coated with a combination of adulticide and larvicide.
Adult mosquitoes are attracted to water inside the cup to lay eggs. When they land on the coated surface, they are killed. If they lay eggs before they die, the larvae that hatch from the eggs are killed with the larvicide. The insecticide and larvicide can be mixed in a special coating material which prevents the insecticides from breaking down. Also the coating is designed to provide a timed release of the insecticides.
The insecticidal coatings can have colors incorporated that are attractive to mosquitoes. This dual action lethal ovitrap would be useful for control of mosquitoes that vector dengue, west Nile virus, yellow fever, and other pathogens.
Embedding the insecticides in coatings within our dual action lethal Ovitrap can protect the active ingredient and/or synergist from degradation by the water in the Ovitrap, and results in slow release of the active ingredient over time to kill mosquitoes. If the mosquitoes lay eggs before they die, a larvicide also embedded in the coating, is protected from degradation, and slowly releases over time to kill any larvae that hatch from the mosquito eggs. The dual action of the Ovitrap assures that the device will not produce mosquitoes as a result of degradation of the adulticide active ingredients.
Further objects and advantages of this invention will be apparent from the following detailed description of the presently preferred embodiments which are illustrated schematically in the accompanying drawings.
Before explaining the disclosed embodiments of the present invention in detail it is to be understood that the invention is not limited in its applications to the details of the particular arrangements shown since the invention is capable of other embodiments. Also, the terminology used herein is for the purpose of description and not of limitation.
The Steps to create an ovitrap with separate adulticide and larvicide layers can include the following:
i. Obtain a preferred coating basis;
ii. Prepare adulticide coating by adding adulticide active ingredient, and, if desired, the additive (CARBONXIDE™) and any synergist;
iii. Prepare larvicidal coating by adding larvicide active ingredient, and, if desired, the additive (CARBONXIDE™) and any synergist;
iv. Coat the bottom half of a container (8-32 oz.) internally, with the larvicidal coating;
v. Coat the top half of a container internally with the adulticidal coating;
vi. Drain holes can be added to the container wall at the midway line between the top adulticide coating and the bottom larvicide coating; and
vii. Attachment devices such as cords, hooks, etc can be added to assist in securing the dual action ovitrap to field locations.
The steps to create an ovitrap with combined adulticide and larvicide layer can include:
The following protocols A, B, C and D list the flowchart methodologies for experiments that were conducted for evaluating the different coatings used.
Protocols A and B referenced above were used as proof-of-concept experiments before the dual-action ovitraps were developed. Insects were exposed to aged insecticidal coatings during the tests.
Protocol C was used to test effect of the adulticide-only coating on adult mosquitoes exposed to treated ovitrap.
Protocol D was used to test adulticide-larvicidal combination in dual action ovitrap. For this experiment, coating containing just adulticide and just larvicide were also used to provide information on the effects of each product alone.
Experiment: 2 h_Mort_A_Aegypti_Aged_Coating Description
For all aging experiments, short-term aging was obtained by storing coated wood panels in lab at room temperature (22° C.), but long-term aging (>24 days) was obtained by placing coated wood panels in oven at 60° C. where 1 day of accelerated age corresponds approximately to 10 days at 22° C.
