摘　　要：蔬菜作物释放的虫害诱导植物挥发物(Herbivore-induced plant volatiles,HIPVs)是蔬菜作物受害虫胁迫后产生的一类启动防御反应的化合物,可以作为蔬菜作物的对外重要信息交流媒介和防御措施实施前体。蔬菜作物通过释放HIPVs来增强自身防御反应、调节昆虫行为和向邻近作物发出“预警信号”,从而直接或间接地抵御植食性昆虫危害。近年来,有关HIPVs的研究已成为昆虫行为学与化学生态学的关注热点。本文系统综述了虫害诱导蔬菜作物挥发物类别、释放特性、生态功能及应用等方面,以期梳理和阐释HIPVs在蔬菜-害虫二级营养结构以及蔬菜-害虫-害虫天敌三级营养结构的化学生态网络中的重要化学信号功能,并对未来该方向的研究进行展望。Herbivore-induced plant volatiles(HIPVs)released by vegetable crops are a class of compounds that initiate defensive response of vegetable crops after being infected by pests.These volatiles can be used as a way to communicate with neighboring plants and insects,and they are also the precursor of implementing defense measures for vegetable crops.The volatile compounds can resist the harm of herbivores directly or indirectly by enhancing defense response by releasing HIPVs,regulating insect behavior,and sending“early warning signals”to neighboring crops.In recent years,the research on HIPVs has become a hot topic of insect behavior and chemical ecology.This article systematically summarizes the species,release characteristics,ecological functions and applications of vegetable volatiles induced by pests based on existing research,in order to card and explain the important chemical signal functions of HIPVs in the chemical ecological network of the secondary nutritional structure and the vegetable-herbivores-natural enemies tritrophic structure,and prospects for future research in this direction.
