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 (
Nepeta cataria
). In another embodiment, the plant volatile is any one or a combination of sesquiterpenoids derived from the fruit of the Osage orange tree (
Maclura pomifera
). Such compositions have repellency against arthropods, such as cockroaches, mosquitoes, mites, ticks, spiders, and so forth.
本发明提供了用于驱除目标害虫的组合物和方法。这些组合物包含一定量的单萜或
倍半萜类化合物,可有效驱除目标区域的目标害虫,单萜或
倍半萜类化合物与载体结合使用。在一个实施方案中,单萜或
倍半萜类化合物来自
生物源,如植物挥发物。在一个特定的实施方案中,植物挥发物是一种单
萜类化合物,例如从猫薄荷(Nepeta cataria)中提取的 "nepetalactone"(或单个 nepetalactone 异构体)。
猫薄荷
).在另一个实施方案中,植物挥发物是提取自奥沙治橙树(Maclura pomifera)果实的
倍半萜类化合物中的任何一种或其组合。
Maclura pomifera
).此类组合物对节肢动物,如蟑螂、蚊子、螨虫、扁虱、蜘蛛等具有驱避作用。
