蜘蛛信息素的研究进展

蜘蛛是农林生态系统中重要的捕食性节肢动物,许多蜘蛛种类具有噬食同类的行为趋向,因而蜘蛛同种个体之间或与猎物之间的信息交流显得尤为重要。化学通讯在蜘蛛种内及种间的信息交流中起着重要的作用,已有大量的研究用行为学的方法证实蜘蛛雌雄之间、亲子之间以及蜘蛛与猎物之间能够依据信息化学物质进行通讯,但蜘蛛信息素的化学结构鉴定以及释放和接收机制等尚缺乏深入的研究。本文就蜘蛛信息化学物质的研究进展作一概述。

SEMIOCHEMICALS OF SPIDERS

Spiders are important predatory arthropods in the agroecosystem.Because spiders are generally aggressive and cannibalistic,they have evolved elaborate means to communicate with each other.Semiochemicals play a critical role in intra-and interspecific communication of spiders.Many researches revealed that spiders can release semiochemicals to convey information between males and females or between spiders and their prey species.However,just a few spider pheromones were identified till now.And the mechanism of producing and receiving of the spider pheromones need to be studied intensively.The research progress in spider semiochemicals was summarized in this review.
