摘　　要：神经肽是昆虫体内仅次于保幼激素和蜕皮激素的重要肽类激素。而速激肽与其他神经肽一样,属于典型的脑-肠肽,具有神经调节、神经递质或激素功能,其首先在粗糙型内质网中合成前体多肽,前体蛋白(多肽)在其N端具疏水结构的信号肽的引导下进入内质网后切除信号肽,然后经过一系列修饰后以颗粒状小分子多肽释放出来。在昆虫生长发育及生理行为方面发挥着同样重要的作用。本文从昆虫速激肽的发现、命名、分子特性、分离鉴定方法以及最新相关研究进展等做了全面的总结,为深入研究其复杂的生物学功能及在微生物-昆虫-植物三级营养中的作用,进一步探索害虫综合治理提供重要依据。Neuropeptide is the major peptide hormone,the second only to juvenile and ecdysone hormone.As the common brain-gut peptide hormone and functioning as central neuromodulators,neurotransmitter and circulating hormones in insects,tachykinin is first synthesized as part of a large preprohormone in the rough endoplasmic reticulum,and shortly after synthesis,the cleavage of the N-terminal signal sequence of the preprohormone results in the formation of prohormone.To release the bioactive hormone,the prohormone matures during the intracellular transport from the rough endoplasmic reticulum to golgi apparatus and finally to secretory granules.Tachykinin also plays multi-function and vital roles in growth and development,and also the role of physiology behavior in insects.In this article,we summarized the detection,nomination,molecular characterization,identification,and the latest research advances of insect tachykinin.And all of them above will shed light on relationships in the biological function and complexity,and tritrophic interactions among the microbe,insect and plant of tachykinin.It also provides a solid foundation for integrated pest management.
