| 中文摘要: |
| 性信息素是昆虫两性通讯的化学信号, 在物种繁衍中担当着重要的角色。以性信息素为基础的害虫诱杀和交配干扰等防治手段具有灵敏度高、选择性强、对天敌安全、不污染环境等优点, 在害虫综合治理和绿色防控体系应用中深受青睐。棉铃虫 Helicoverpa armigera 是一种世界性农业害虫, 具有适应能力强和寄主广泛的特点, 条件适宜时常大面积暴发成灾。以棉铃虫为代表的醛类性信息素的生物合成和调控过程, 是目前研究较早也较为透彻的一类性信息素。本研究概述了棉铃虫性信息素的组分和功能, 生物合成时的信号转导途径和调控机制, 以及性信息素前体的生成和特异性组分的碳链修饰过程, 并总结了当前研究的不足, 旨在为今后的基础研究和生产应用提供指导。 |
| 英文摘要: |
| Sex pheromones serve as chemical signals for insect sexual communication and play an important role in species reproduction. Sex pheromone-based pest control techniques (like trapping and mating interference) are favored by integrated pest management and green control systems due to its characteristics of high sensitivity, strong selectivity, safety to natural enemies, and environmental friendliness. Helicoverpa armigera is a worldwide agricultural pest with strong adaptability and a wide range of hosts. This pest tends to break out on a large scale under favorable conditions. The biosynthesis and regulatory mechanism of aldehyde-type sex pheromones have been well elucidated using H. armigera as a model. This study summarized the components and functions of sex pheromones in H. armigera, the signal transduction pathways and regulatory mechanisms during biosynthesis, as well as the generation of sex pheromone precursors, and the carbon chain modification process of specific components. Moreover, this article also summarized the deficiencies of current research and provides a guidance for future basic research and practical applications. |
