大小蠹信息化学物质研究与应用概述

Research and application of semiochemicals of Dendroctonus spp

大小蠹多数侵染活立木或伐倒木、过火木等,能在较短的时间内暴发流行,并可引起次生性病虫害,是许多国家重点防治对象。信息化学物质作为大小蠹种内和种间通讯载体,在其综合治理中发挥着重要作用。作者综述了大小蠹信息素的产生、释放,信息素组分及其功能,大小蠹寄主、非寄主挥发物组分及其对小蠹入侵行为的影响,为大小蠹的综合防治提供参考。

Dendroctonus spp. are important forest pests in many countries, which always invade standing timbers or felled trees. It can break out in a short-period and arise secondary pest disaster. As the intra-specific and inter-specific communication carrier, semiochemicals provide new methods for comprehen-sive management of Dendroctonus spp. The review summarizes the production and release, compositions and functions of pheromones and analyses the influences of host and non-host volatiles on the behavior of bark beetles in order to provide reference for comprehensive control of Dendroctonus spp.
