| 20世纪90年代棉铃虫大暴发, 我国棉花产业和经济遭受重大损失, 郭予元院士带领团队研究人员, 深入探究棉铃虫的发生规律和控制策略, 揭示了棉铃虫迁飞扩散规律及其与寄主植物互作关系, 明确了转基因抗虫棉花生物安全和靶标害虫抗性机制, 解析了棉花-棉铃虫-侧沟茧蜂三级营养间的化学通讯机制, 使得大灾之年棉区棉铃虫为害得到有效控制, 并对促进我国农业昆虫学基础研究起到了重要的学科引领作用。其中, 对棉花-棉铃虫-中红侧沟茧蜂三级营养间化学通讯机制的研究, 开创了棉铃虫治理新思路和新途径。本文回顾了郭予元院士在该领域研究中做出的重要贡献, 主要包括棉花-棉铃虫-侧沟茧蜂三级营养通讯间关键挥发性化合物的鉴定, 棉铃虫及其寄生性天敌中红侧沟茧蜂嗅觉行为分子机制的研究, 棉花虫害诱导关键挥发物生物合成机制的探索, 及基于三级营养关系设计昆虫行为调控剂在棉铃虫综合治理中的应用。上述研究成果为阐明棉铃虫及夜蛾科昆虫、中红侧沟茧蜂等膜翅目天敌寻找寄主的化学通讯机制奠定了坚实基础, 为设计害虫绿色防控策略提供了新方向。 |
| 英文摘要: |
| The outbreak of cotton bollworm, Helicoverpa armigera (Hübner), in the 1990s caused great losses to China’s cotton industry and economy. Academician Guo Yuyuan led the research team to carry out a series of studies, including deeply exploring the occurrence law and control strategy of cotton bollworm, revealing the migration and distribution regularity of cotton bollworm and its interaction with host plants, analyzing the chemical communication mechanism in tritrophic interactions among cotton, cotton bollworm, and parasitoid Microplitis mediator, and clarifying the biosafety of transgenic insect-resistant cotton and the resistance mechanism of target pests, which effectively controlled the damage of cotton bollworm, and played an important role in leading the discipline in promoting the basic research of agricultural entomology in China. The research on the chemical communication mechanism among the tritrophic interactions of cotton, cotton bollworm and parasitoid has created a new strategy to control cotton bollworm. This paper reviews the important contributions made by Academician Guo Yuyuan in the research of this field, mainly including identification of key volatile compounds among the tritrophic interactions, research on the olfactory mechanism of cotton bollworm and parasitoid, synthesis mechanism of key herbivore-induced plant volatiles, and application of insect behavior regulators based on the finding in the integrated management of cotton bollworm. The above research has laid a good foundation for elucidating the chemical communication mechanism of noctuidae insects and Hymenopteran natural enemies in searching for their hosts, and provided a new direction for designing efficient strategies for biological pest control. |
