小蠹虫信息化合物作用研究概述

Function of bark beetle semiochemicals

小蠹虫具有复杂的种间和种内信息化合物,其主要作用是调节和控制对寄主树木的选择、入侵及危害,进而调控小蠹虫在森林生态系统内的种群密度和生态分布。本文简要概述了信息化合物在小蠹虫寄主选择、入侵、定居、繁殖等一系列行为中的作用,并进一步阐述了小蠹虫寄主选择理论,重点阐明了寄主与非寄主植物挥发物的作用。

Bark beetles use inter and intra-specific semiochemicals to regulate and control their host selection,invasion and attacking,and,in turn,to regulate population density and ecological distribution in forest ecosystem.This review briefly summarizes the functions of semiochemicals in various bark beetle behaviors such as host selection,attacking,settlement,and reproduction,and describes the theories of bark beetle host selection,with emphasis on host and non-host volatiles.In addition,the identified bark beetl...
