Abstract

An insect control formulation including methyl eugenol, cue lure and a biodegradable wax carrier is a surprisingly effective attractant for Oriental fruit flies ( Bactrocera dorsalis ) and Melon flies ( Bactrocera cucurbitae ). Formulation embodiments that include at least one insect toxicant are surprisingly effective for use in fruit fly MAT attract and kill systems, and are suitable for on-crop or off-crop uses. Formulation embodiments can be provided as aqueous emulsions having viscosities appropriate for use in aerial or backpack spray applications or for delivery using caulk gun-type or grease pump-type devices. Other formulation embodiments can be provided as solid blocks, granules or powders.

First claim

What is claimed is:

1 . An insect control formulation, comprising:
methyl eugenol; cue lure; and a biodegradable wax carrier; wherein said methyl eugenol and said cue lure are dispersed in said biodegradable wax carrier; wherein said biodegradable wax carrier is operable to release the methyl eugenol and cue lure over a period of time extending at least four weeks; and wherein release of the methyl eugenol and cue lure is effective for attracting at least a first fruit fly species targeted by cue lure and at least a second fruit fly species targeted by methyl eugenol without antagonistic effects.

2 . The formulation in accordance with claim 1 , wherein:
said methyl eugenol is from about 1% to about 60% of the formulation by weight; said cue lure is from about 1% to about 30% of the formulation by weight; and said biodegradable wax carrier is from about 10% to about 90% of the formulation by weight.

3 . The formulation in accordance with claim 1 , further comprising:
water; wherein said formulation comprises a fluid suspension comprising solid particles of said biodegradable wax carrier suspended in said water, and wherein said methyl eugenol and said cue lure are entrained in one or both of said solid particles and said water.

4 . The formulation in accordance with claim 3 , wherein:
said methyl eugenol is from about 5% to about 45% of the formulation by weight; said cue lure is from about 1% to about 20% of the formulation by weight; and said biodegradable wax carrier is from about 20% to about 80% of the formulation by weight.

5 . The formulation in accordance with claim 3 , wherein said fluid suspension is in the form of an emulsion.

6 . The formulation in accordance with claim 1 , further comprising one or more insect toxicants.

7 . The formulation in accordance with claim 6 , wherein:
said methyl eugenol is from about 1% to about 60% of the formulation by weight; said cue lure is from about 1% to about 30% of the formulation by weight; said biodegradable wax carrier is from about 10% to about 90% of the formulation by weight; and said one or more insect toxicants is from about 0.002% to about 25% of the formulation by weight.

8 . The formulation in accordance with claim 6 , wherein said one or more insect toxicants comprise Spinosad.

9 . The formulation in accordance with claim 3 , wherein said formulation is in the form of an emulsion comprising solid particles of said biodegradable wax carrier suspended in said water, and wherein said methyl eugenol and said cue lure are entrained in one or both of said solid particles and said water.

10 . The formulation in accordance with claim 9 , wherein the wax carrier comprises a member selected from the group consisting of paraffin wax, carnauba wax, beeswax, candelilla wax, fruit wax, lanolin, shellac wax, bayberry wax, sugar cane wax, microcrystalline wax, ozocerite, ceresin, montan wax, and combinations thereof.

11 . The formulation in accordance with claim 9 , wherein the wax carrier comprises paraffin wax.

12 . The formulation in accordance with claim 9 , wherein the wax carrier consists essentially of paraffin wax.

13 . The formulation in accordance with claim 9 , wherein the wax carrier is present in an amount from about 20% to about 80% by weight.

14 . The formulation in accordance with claim 9 , further comprising one or more additives selected from the group consisting of lipids, emulsifiers, plasticizers, UV blockers and absorbers, antimicrobials, antioxidants and volatility suppressants.

15 . The formulation in accordance with claim 14 , wherein the one or more additives is present in an amount from about 0.001% to about 20% by weight of the formulation.

16 . The formulation in accordance with claim 14 , wherein the additive is present in an amount from about 0.1% to about 10% by weight of the formulation.

17 . The formulation in accordance with claim 14 , wherein the additive comprises an emulsifier in an amount up to about 10% by weight of the formulation.

18 . The formulation in accordance with claim 14 , wherein the additive comprises an emulsifier selected from the group consisting of lipids, soy oil, lecithins, modified lecithins, monoglycerides, diglycerides, sorbitans, and fatty acids, and combinations thereof.

19 . The formulation in accordance with claim 14 , wherein the additive comprises an antioxidant in an amount of from about 0.1% to about 3% by weight of the formulation.

20 . The formulation in accordance with claim 19 , wherein the antioxidant comprises a member selected from the group consisting of vitamin E, butylated hydroxyanisole, and butylated hydroxytoluene.

21 . The formulation in accordance with claim 14 , wherein the emulsion comprises from about 20% to about 80% by weight of paraffin wax, from about 5% to about 45% by weight of methyl eugenol, from about 1% to about 20% by weight of cue lure, and from about 0.001% to about 10% by weight of one or more additives selected from the group consisting of emulsifiers, plasticizers, and antioxidants combined.

22 . The formulation in accordance with claim 9 , further comprising one or more insect toxicants.

23 . The formulation in accordance with claim 9 , wherein the emulsion is sprayable, squirtable or spreadable.

24 . The formulation in accordance with claim 23 , wherein the emulsion is sprayable.

25 . The formulation in accordance with claim 1 , wherein said biodegradable wax carrier forms a solid block, granule or powder comprising a porous matrix structure, and wherein said methyl eugenol and said cue lure are entrained within said porous matrix structure.

26 . The formulation in accordance with claim 1 , wherein the first fruit fly species includes melon flies and the second fruit fly species includes oriental fruit flies.

27 . An insect control formulation comprising:
from about 5% to about 45% by weight of said formulation of methyl eugenol; from about 1% to about 20% by weight of said formulation of cue lure; from about 20% to about 80% by weight of said formulation of a biodegradable wax carrier; and from about 0.1% to about 20% by weight of said formulation of an insect toxicant; wherein said insect toxicant is selected from Spinosad and spinetoram; wherein said formulation comprises a sprayable emulsion; wherein said methyl eugenol, said cue lure and said insect toxicant are dispersed in said biodegradable wax carrier; wherein said biodegradable wax carrier is operable to release the methyl eugenol and cue lure over a period of time extending at least four weeks; and wherein said release of the methyl eugenol and cue lure is effective for attracting at least a first fruit fly species targeted by the cue lure and at least a second fruit fly species targeted by the methyl eugenol without antagonistic effects.
