Abstract
Compositions and heterodissemination methods for controlling unwanted target insect populations are disclosed. In preferred embodiments, the target insects are mosquitos or house flies and the heterospecific insects are non-biting midges and soldier flies respectively.
Claims15
A method for eradicating a target insect infestation, said target insect infestation being harmful to humans or livestock, comprising;
- a) providing a container comprising a heterospecific, non-harmful insect population having the same habitat as said target insect;
- b) coating the non-harmful insect population of step a) with a first larvicidal formulation comprising an oil formulation, followed by application of a second larvicidal formulation comprising a powder formulation, such that the bodies of said non-harmful insect population are coated with both of said oil and powder formulations;
- and
- c) placing said container in the vicinity of one or more target insect larval habitats or releasing said coated non harmful insect population under conditions whereby said heterospecific non-harmful insects migrate to, and contaminate said one or more target insect larval habitats with said first and second larvicidal formulations;
- said contamination killing target insect larvae in said one or more target insect habitats, thereby controlling said target insect infestation.
A population of heterospecific insects coated with an oil formulation containing 20% pyriproxyfen, 72% methylated seed oil as carrier and 8% polysorbate 20 as emulsifier and a powder formulation containing 60% pyriproxyfen, 28% fumed silica as carrier and 12% Sodium Dodecyl Sulfate as emulsifier.
An apparatus for application of IGR to heterospecific insects consisting of a treatment chamber with a spray hole for application of IGR to heterospecific insects of interest, an air permeable cage, and a population of heterospecific insects, said chamber having the air permeable cage contained within said chamber, said cage housing the population of heterospecific insects to be treated with said IGR.
A method for eradicating a target insect infestation, said target insect infestation being harmful to humans or livestock, comprising;
- a) providing a container comprising a heterospecific, non-harmful insect population having the same habitat as said target insect;
- b) coating the non-harmful insect population of step a) with a first larvicidal formulation comprising an oil formulation, followed by application of a second larvicidal formulation comprising a powder formulation, such that the bodies of said non-harmful insect population are coated with both of said oil and powder formulations;
- and
- c) placing said container in the vicinity of one or more target insect larval habitats or releasing said coated non harmful insect population under conditions whereby said heterospecific non-harmful insects migrate to, and contaminate said one or more target insect larval habitats with said first and second larvicidal formulations;
- said contamination killing target insect larvae in said one or more target insect habitats, thereby controlling said target insect infestation, wherein after coating with said oil and powder formulations, said heterospecific insects carry up to 0.036 mg of active ingredient.
