International Classification:

A01N 31/04

US Classification:

514729, 424405, 424406, 424DIG 10, 424736, 514919

Abstract:

This invention provides compositions and methods useful for repelling target pests. The compositions comprise an amount of a monoterpenoid or sesquiterpenoid effective to repel a target pest from a target area, the monoterpenoid or sesquiterpenoid in combination with a carrier. In one embodiment, the monoterpenoid or sesquiterpenoid is from a biorational source, such as a plant volatile. In a particular embodiment, the plant volatile is a monoterpenoid, such as “nepetalactone” (or the individual nepetalactone isomers) derived from catnip (). In another embodiment, the plant volatile is any one or a combination of sesquiterpenoids derived from the fruit of the Osage orange tree (). Such compositions have repellency against arthropods, such as cockroaches, mosquitoes, mites, ticks, spiders, and so forth.

A61K 31/34

US Classification:

514469, 514457, 424405

Abstract:

Soybean volatile compounds, soybean aphid-induced volatile compounds and soybean aphid sex pheromones are semiochemicals of the invention used to suppress soybean aphid population. Methyl salicylate is an embodiment of a soybean aphid-induced volatile compound useful in the invention. Benzaldehyde is an embodiment of a soybean host plant volatile compound useful in the invention. Also useful as sex pheromones are nepetalactol and nepetalactone. The compounds may be blended in a preferred embodiment.

US Classification:

424406, 42419518, 424405, 424736, 424DIG 10, 514729, 514919

Abstract:

The compositions comprise an effective repellent amount of one or more monoterpenoids, one or more sesquiterpenoids or a blend of one or more monoterpenoids and one or more sesquiterpenoids in combination with a carrier, wherein the compositions are formulated to repel a target pest from a target area. In one embodiment, the one or more monoterpenoids, and/or one or more sesquiterpenoids are from a biorational source, such as a plant volatile. In one embodiment, the one or more sesquiterpenoids are oxygen-containing sesquiterpenoids. In a particular embodiment, the plant volatile is a monoterpenoid, such as “nepetalactone” (or the individual nepetalactone isomers) derived from catnip (). In another embodiment, the plant volatile is additionally or alternatively a sesquiterpenoid derived from the fruit of the Osage orange tree (), Siam wood or the plant. Such compositions have repellency, including long term repellency, against arthropods.

Abstract:

This invention provides compositions and methods useful for repelling target pests. The compositions comprise an amount of a monoterpenoid or sesquiterpenoid effective to repel a target pest from a target area, the monoterpenoid or sesquiterpenoid in combination with a carrier. In one embodiment, the monoterpenoid or sesquiterpenoid is from a biorational source, such as a plant volatile. In a particular embodiment, the plant volatile is a monoterpenoid, such as ânepetalactoneâ (or the individual nepetalactone isomers) derived from catnip ( ). In another embodiment, the plant volatile is any one or a combination of sesquiterpenoids derived from the fruit of the Osage orange tree ( ). Such compositions have repellency against arthropods, such as cockroaches, mosquitoes, mites, ticks, spiders, and so forth.
