Abstract

The invention provides a screening method for identifying an insect-specific TRPA1 modulator by comparing modulation of an insect TRPA1 and a mammalian TRPA1. The invention further provides method of insect control by applying to an insect a insect-specific TRPA1 modulator identified by the screening method.

First claim

What is claimed:

1. A method of insect control, the method comprising contacting an insect in need of control with an effective amount of an insect-specific transient receptor potential ion channel A1 (TRPA1) modulator compound selected from allyl isothiocyanate (AITC) or N-methyl-maleimide (NMM).

2. The method of claim 1 , wherein the compound is an inhibitor or activator of TRPA1 activity.

3. The method of claim 1 , wherein the insect in need of control is selected from the group consisting of fleas, rat fleas, oriental rat fleas, flies, black flies, sand flies, mosquitoes, horse flies, deer flies, eye gnats, house flies, blow flies, flesh flies, tsetse flies, lice, human lice, true bugs, assassin bugs, kissing bugs, and any combinations thereof.

4. The method of claim 1 , wherein the insect in need of control is a disease vector, a parasite, an agricultural pest, or a horticultural pest.

5. The method of claim 1 , wherein compound is applied to a locus of the insects.

6. The method of claim 5 , wherein said locus is a breeding locus or a feeding locus.

7. The method of claim 1 , wherein the compound is formulated with a food source.

8. The method of claim 1 , wherein the compound is formulated with sucrose.

9. The method of claim 1 , wherein the compound modulates thermo- and/or chemo-sensing in the insect.

10. The method of claim 1 , wherein the compound inhibits feeding of the insect in need of control.
