植物挥发物对昆虫的驱避和引诱作用研究进展

Advances of Research on Repellency and Attraction of Plant Volatiles to Insects

植物挥发物属于植物次生化学物质,在促进植物与昆虫交流、调节昆虫行为方面发挥着重要作用。植物挥发物可以驱避害虫保护植物、参与害虫的寄主选择行为或者作为吸引天敌定位害虫的信号物质。基于植物挥发物开发的驱避剂可用于田间害虫防治,引诱剂可用于诱捕害虫或诱集天敌防御害虫,此外,昆虫引诱剂与昆虫信息素或黄板联用可以达到增效作用。本文综述了近年来国内外有关植物挥发物对昆虫驱避和引诱作用的研究概况,总结了其在田间应用中亟需深入研究的问题,并分析了其在农业绿色发展中的应用前景和重要价值。

Plant volatiles are plant secondary chemicals, which play important roles in promoting the communication between plants and insects and regulating insect behavior. Plant volatiles can repel pests, protect plants, participate in the host selection behavior of pests, or serve as signal substances to attract natural enemies to locate pests. Repellents developed based on plant volatiles can be used for pest control in the fields, and attractants can be used to trap pests or induce natural enemies to defend against pests. In addition, insect attractants can achieve a synergistic effect when combined with insect pheromones or yellow sticky trap. In this paper, we summarized the research situation of plant volatiles on insect repellency and attraction at home and abroad in recent years, and analyzed the problems that needed further studies in the field application, then its application prospect and important values in the green development of agriculture were analyzed.
