摘要: 以小蠹虫和天牛为主的蛀干昆虫是为害林木的重要经济害虫,常对森林生态系统造成重大灾害.本文以林业主要害虫——小蠹虫和天牛为例,综述了树木、蛀干害虫和其天敌组成的三级营养系统间相互关系的研究概况,从不同侧面介绍了近十年来在引诱天敌的信息化学物质的释放部位、活性化合物的鉴定、挥发性化合物的释放动态等方面的研究成果,同时对于天敌对信息化学物质的选择性、天敌视觉在寻找寄主或猎物方面的作用以及是否涉及到影响天敌行为的三级营养以外的其它生物活性物质等的研究进展作了简略介绍.

Abstract: Trunkborers, mainly bark beetles and cerambycids, are the important insect pests of forests, which can cause serious damage to forest ecosystem. Taking bark beetle and long-horned beetle as the examples, this paper summarized the research progress on the tritrophic system of tree-trunkborer-insect natural enemy association, with the past ten years research results on semiochemicals release source, active compounds identification, and release dynamics of volatiles introduced. The chemical signals selection of natural enemies and their visual function in finding hosts or preys, as well as whether there were other biological active compounds beyond this tritrophic system, which could influence the natural enemy’s behaviors, were also discussed.
