摘　　要：植物挥发物在寄生蜂的寄主栖息地定位中起着重要作用。在自然状态下,某些健康植物能释放对寄生蜂有吸引作用的挥发物。当植物受到植食性昆虫为害后,可引起植物的间接防御,即产生对一定种类寄生蜂具引诱作用的挥发物来保护自己。此外,害虫的产卵也能诱导部分植物产生引诱天敌的物质。对于植食性昆虫取食植物诱导的挥发物研究较深入,而其产卵对植物挥发物的影响研究较少。本文主要综述近年国内外有关植物挥发物对寄生蜂寄主定位影响的研究概况,可望为害虫综合治理研究提供参考。Plant volatiles play an important role in host habitat location by insect parasitoid.Some parasitoids exhibit innate responses to plant volatiles emanated by healthy plants.Indirect defense was induced in plants when attacked by herbivores through releasing herbivore-induced volatiles to attract specific natural enemies.In addition,pest oviposition-induced plant cues can arrest parasitoid wasps during host location.In recent years,many reports have been published on herbivore-induced plant volatiles,but few focused on the effects of oviposition-induced-volatiles on plant and natural enemies.In this paper,effects of plant volatiles on host location of parasitoids were summarized,which may provide a reference for further study of integrated pest management.
