摘要：林木蛀干类害虫具有高度的隐蔽性,是林业上的一类重要害虫,也是目前世界上最难防治的害虫类群之一。寄生蜂在与寄主长期的协同进化过程中,形成了搜索、发现和攻击寄主害虫的独特机制,能够有效地找到并寄生它们。总结了寄生性天敌寻找、发现并成功定位隐蔽性寄主害虫的行为学机制。寄生蜂可以利用来自嗅觉的化学信息物质(如寄主、寄主粪便、虫道共生菌的挥发性气味)、寄主成虫的化学通讯物质、来自视觉的植物表面色差信息、来自触觉的寄主保护物性状特征、来自寄主取食和运动所产生的介质振动信号以及来自寄主活动和代谢的红外辐射等多种途径有效地发现隐蔽性害虫的位置,从而完成寄生行为。有些寄生蜂还能综合利用来源不同的多种信息,从而提高寄主定位的可靠性和准确性。本文还对寄生蜂寻找寄主的这些线索在生物防治上可能的利用途径和前景进行了讨论。这对促进我国在该领域的研究,充分利用天敌昆虫,提高生物防治效率具有参考价值。
Wood borers are important forest insect pests and difficult to control due to their concealed behavior.However,parasitic wasps can effectively ascertain and parasitize wood borers as well as other concealed pests using special searching,finding and attacking mechanisms,developed during the course of long-term coevolution with their hosts.The present paper summarizes the behavioral mechanisms of parasitic wasps involved in searching and locating their concealed hosts.Parasitic wasps can accurately find the location of their hidden hosts and then parasitize them,usually using olfactory semiochemicals from hosts（lavare and adults）,host frass and symbiotic microorganisms in host galleries;visual signals from color contrast of plant surface;contact stimuli from characters of host physical defense;substrate vibrations produced by host feeding and movement,and infrared radiation from host activities and metabolizability.Some parasitic wasps may integrate the information of several stimuli from different sources for enhancing the reliability and accuracy of host locations.In addition,the potentials for utilizing their host location signals in biological control using parasitoids are discussed.
