Methods of controlling insects
View Patent ↗Methods of controlling insects include applying at least one spinosyn compound to a locus of a neonicotinoid-resistant insect, such as a strain of Drosophila melanogaster resistant to a neonicotinoid compound. The spinosyn compound may be a mixture of spinosyn A and spinosyn D. The spinosyn compound may cause up to approximately ten times increased mortality in the neonicotinoid-resistant insect compared to an insect susceptible to a neonicotinoid compound.
1. A method of controlling insects, the method comprising:
applying a spinosyn compound to a locus of an insect having at least one lesion in at least one of Dα1 subunit and Dβ2 subunit of the nicotinic acetylcholine receptor,
wherein the method achieves up to approximately ten times increased mortality in the insect having at least one lesion in at least one of Dα1 subunit and Dβ2 subunit of the nicotinic acetylcholine receptor, compared to an insect lacking the at least one lesion.
2. The method of claim 1 , wherein the insect having at least one lesion in at least one of Dα1 subunit and Dβ2 subunit of the nicotinic acetylcholine receptor comprises an insect in the order of Lepidoptera, Diptera, Homoptera, Thysanoptera, Coleoptera, Anoplura, Dermaptera, Blattaria, Hemiptera, Hymenoptera, Isoptera, Mallophaga, Siphonaptera, Thysanura, Acarina, Symphyla, Nematoda, or Orthoptera.
3. The method of claim 1 , wherein applying the spinosyn compound comprises applying a spinosad compound.
4. The method of claim 3 , wherein applying a spinosad compound comprises applying an insecticide consisting essentially of from approximately 50% by volume to approximately 90% by volume of spinosyn A and from approximately 10% by volume to approximately 50% by volume of spinosyn D.
5. The method of claim 1 , wherein applying the spinosyn compound comprises applying a spinetoram compound.
6. The method of claim 1 , wherein the insect is resistant to at least one of acetamiprid, clothianidin, dinotefuran, flupyradifurone (BYI 02960), imidacloprid, imidaclothiz, nitenpyram, thiacloprid, and thiamethoxam.
7. A method of controlling insects, comprising:
applying a spinosyn compound to a locus of a Drosophila melanogaster having at least one lesion in at least one of Dα1 subunit and Dβ2 subunit of the nicotinic acetylcholine receptor.
8. The method of claim 7 , wherein applying the spinosyn compound comprises applying the spinosyn compound to the locus of a Drosophila melanogaster having at least one lesion in a Dα subunit of the nicotinic acetylcholine receptor.
9. The method of claim 7 , wherein applying the spinosyn compound comprises applying the spinosyn compound to the locus of a Drosophila melanogaster having at least one lesion in a Dβ2 subunit of the nicotinic acetylcholine receptor.
10. The method of claim 7 , wherein applying the spinosyn compound comprises applying the spinosyn compound to the locus of a Drosophila melanogaster having lesions in a Dα1 subunit and a Dβ2 subunit of the nicotinic acetylcholine receptor.
11. A method of controlling insects, comprising:
applying a spinosad compound to a locus of a Drosophila melanogaster having at least one lesion in at least one of the Dα1 subunit and the Dβ2 subunit of the nicotinic acetylcholine receptor.
12. The method of claim 11 , wherein applying a spinosad compound comprises applying an insecticide consisting essentially of spinosyn A and spinosyn D.
13. The method of claim 11 , wherein applying the spinosad compound comprises applying the spinosad compound to the Drosophila melanogaster having a mutation in the Dα1 subunit of the nicotinic acetylcholine receptor.
14. The method of claim 11 , wherein applying the spinosad compound comprises applying the spinosad compound to a Drosophila melanogaster having a mutation in the Dβ2 subunit of the nicotinic acetylcholine receptor.
15. The method of claim 11 , wherein the method achieves up to approximately ten times more potency against the Drosophila melanogaster having at least one lesion in at least one of the Dα1 subunit and the Dβ2 subunit of the nicotinic acetylcholine receptor, compared to Drosophila melanogaster lacking the at least one lesion.
16. A method of controlling insects, comprising applying an insecticide consisting of from approximately 50% by volume to approximately 90% by volume of spinosyn A and from approximately 10% by volume to approximately 50% by volume of spinosyn D to the locus of a Drosophila melanogaster having lesions in a Dα1 subunit and a Dβ2 subunit of the nicotinic acetylcholine receptor in an effective amount to achieve up to approximately ten times increased mortality in said Drosophila melanogaster compared to a Drosophila melanogaster lacking the lesions.
