摘要：为今后VOCs在林木抗虫新品种的选育、抗虫机理及森林生态恢复等研究中的应用提供参考,综述了树木VOCs释放的主要类型及VOCs对植食性昆虫的作用。树木挥发物(VOCs)在森林病虫害防治中具有昆虫定位和自身防御双重作用,主要包括异戊二烯、单萜烯、其他活性物质等,其释放受生物因素和非生物因素影响;VOCs对植食性昆虫具有吸引、趋避以及吸引天敌等方面作用;特异性VOCs的鉴定与分离比较困难,还需从分子水平发掘树木VOCs中具有防御作用的关键组分。通过VOCs这个桥梁,对新的预防和控制虫害方法以及抗虫树种选育具有非常重要的理论意义和实践价值。
The study was done to provide the theoretics for the further study of VOCs（Volatile organic compounds） on the selection of insect-defence species,mechanism of insect-defence,ecological control,and ecological restoration of forest.The current advance was reviewed of the species of VOCs in trees and its functions of VOCs on insects.Tree VOCs had dual roles in control of herbivore-insect：attracting the insects to locate and attack host trees,and providing defensive system for trees,and included isoprene,monoterpene and other reactive VOCs,et al.,whose emissions were affected by biotic and abiotic factors.VOCs＇functions on insects included the attraction and repellency of insects and its attraction to natural enemies.However,it is difficult to isolate and identify the specific VOCs to insects,which needs to discover the key elements regulating the emission of VOCs at the molecular level.Finally,the foreground of VOCs on ecological controls of tree pests suggested that it will be theoretical and practical for the new methods of defending and controlling insects,and selection of insect-defence trees by the＇bridge＇of VOCs.
