摘要
针叶树小蠹在扬飞扩散过程中,要有效地依靠嗅觉机制鉴别寄主和非寄主植物的气味,以便在行为反应方面快速定位寄主,降低不利因素对种群的影响。不同的非寄主植物挥发物可以从生境、树种及个体水平上发挥不同的驱避作用。综述非寄主挥发物的范畴和作用、小蠹虫的嗅觉识别及行为反应,提出加强国内针叶树小蠹非寄主挥发物研究与开发的方向,以期为小蠹虫综合管理技术开发提供借鉴和参考。
Relying on the olfactory mechanism to recognize odors from the host and nonhost plants,the phytophagous insects can behaviorally orientate the host trees rapidly to mitigate the influence from detimental environmental impacts.Various nonhost volatiles may exert to different degrees repellent effects from nonhost habitat,species and unsuitable hosts.In this paper,we reviewed the category and functions of the nonhost volatiles,olfactory recognition by electrophysiological means as well as the behavioral responses of the conifer bark beetles to nonhost volatiles.Furthermore,the direction for research and potential use of nonhost volatiles in conifer bark beetle management in China were put forward.
