实夜蛾属和铃夜蛾属昆虫性信息素通讯系统的研究进展

The sex-pheromone communication system of Heliothis/Helicoverpa species(Lepidoptera:Noctuidae)

实夜蛾属Heliothis和铃夜蛾属Helicoverpa昆虫的性信息素通讯系统主要包括雌蛾的性信息素合成和雄蛾对性信息素接收两个方面 ,每方面都有分子、细胞、系统水平上进行协同作用的生物过程。性信息素生物合成激活肽 (PBAN)与其受体作用 ,启动信号转导系统 ,从而激活合成性信息素的酶系统来合成性信息素 ,利用化学和生物测定的方法鉴定出具有诱蛾活性的性信息素腺体组分及行为功能 ;性信息素分子与性信息素结合蛋白 (PBP)的复合体同受体相互作用 ,启动信号转导系统 ,诱导产生神经信号 ,从而引起一系列性行为反应。这些生物过程受到各种内部和外部因素的影响。

Female sex-pheromonal synthesis and male sex-pheromonal reception are two aspects of the sex-pheromonal communication system of Heliothis/Helicoverpa species. Coordinated biological activity at the molecular,cellular,and system levels are involved in the system. The interaction between PBAN and its receptor triggers signal transduction and activates sex-pheromone synthesizing enzymes resulting in the synthesis of sex pheromone. Some sex pheromone components that attract male moths had been identified by chemical and bioassays. The interaction between the pheromone-PBP complex and its receptor triggers signal transduction and induces nervous impulses which finally result in a sequence of sexual behaviors. Many different internal and external factors affect these processes.
