用嗅觉仪研究了两种捕食性叶螨Scolothrips takahashii和Oligota kashmirica benefica对茉莉酸（JA）水溶液和水杨酸甲酯（梅萨）气体处理后的挥发性化合物的反应。成年雌性O.当与未侵染的叶相比时，克什米尔棉表现出对JA+ MeSA处理的叶的显著偏好。与此相反，S. Takahashii显著地偏好梅萨-和JA+ MeSA处理的叶而不是未侵染的叶。与未侵染的叶子相比，捕食者没有表现出任何偏好JA处理的叶子。研究结果表明，在农业生态系统中，可以通过控制植食性天敌的行为来控制植食性害虫。这是第一份报告表明，梅萨可以是一个有用的工具，用于提高蜘蛛螨的肉食性天敌的有效性。
The responses of two insect predators of spider mites, Scolothrips takahashii (Thysanoptera: Thripidae) and Oligota kashmirica benefica (Coleoptera: Staphylinidae), to volatile compounds from leaves treated with aqueous jasmonic acid (JA) and/or gaseous methyl salicylate (MeSA) in an olfactometer were examined. Adult females of O. kashmirica benefica exhibited a significant preference for JA+MeSA-treated leaves when compared with uninfested leaves. In contrast, adult females of S. takahashii significantly preferred MeSA- and JA+MeSA-treated leaves to uninfested leaves. Neither predator showed any preference for JA-treated leaves when compared with uninfested leaves. The results argue in favor of manipulating the behavior of natural enemies of herbivores as a method of biological control against herbivorous pests in agroecosystems. This is the first report to suggest that MeSA can be a useful tool for enhancing the effectiveness of carnivorous natural enemies of spider mites.
