虫粪中信息化学物质的研究进展

Progress in research on semiochemicals in insect frass

排便是昆虫的一个重要生理过程,排便行为不仅可以清除食物残渣,而且可以释放某些化学信息,进而影响昆虫同种或异种之间的相互作用。昆虫粪便中的信息化学物质不仅影响同种昆虫的聚集、求偶行为,而且可以影响同种和异种昆虫的产卵行为。此外,虫粪还能为其天敌昆虫的寄主定位和识别提供信息,并能通过诱导植物的防御反应抑制植食性昆虫的取食行为。本文根据国内外的相关研究,对虫粪中存在的信息化学物质进行了分类总结,并介绍了虫粪信息化合物在害虫防治中的应用,还讨论了目前存在的问题和研究前景。

Defecation is an important physiological processes in insects which not only eliminates digestive waste,but can also release semiochemicals that play a role in intraspecies or interspecies interactions.Insect frass semiochemicals affect intraspecies’aggregation,calling behavior and oviposition.Host semiochemicals are used by predators and parasites to locate and identify prey and hosts,respectively,and inhibit the feeding behavior of phytophagous insects by inducing plant defenses.This paper classifies and summarizes semiochemicals in insect frass based on published domestic and foreign research,and introduces their application in IPM.Problems in this field are discussed.
