中文摘要：
玉米是重要的粮食作物,玉米钻蛀性害虫是玉米生产上为害最重的害虫,其为害严重影响玉米的产量和品质。农药的应用和Bt抗虫玉米的种植在一定程度上有效地控制了玉米钻蛀性害虫的为害,但随着化学防治带来的环境和食品安全问题以及人们对转Bt玉米的食用和环境安全的担心,利用玉米自身的抗虫性控制钻蛀性害虫为害显得尤为重要。玉米对钻蛀性害虫的抗虫机制主要涉及玉米次生代谢产物和细胞壁结构成分等生理生化特性以及茎秆外表皮穿刺强度等物理结构特性等。本文从生理生化特性和物理结构特性方面总结了玉米抗虫性机制,并针对玉米抗虫机制的研究现状提出建议和展望,以期为培育抗性品种以及钻蛀性害虫的综合治理提供参考。
英文摘要：
Corn is a major food crop in the world. Corn borers are the most destructive insect pests, which can substantially reduce the yield and quality of corn. Chemical control and genetically modified insect resistant corn could effectively control corn borer damage to certain degree. However, as the environmental and food safety concerns caused by insecticide application and increasing public concern of genetically modified insect resistant corn in food and ecological safety, the research of corn resistance mechanisms to corn borers is of more important significance in reducing corn borer damage. Mechanisms of resistance to stem borers, including physiological and biochemical factors, such as secondary metabolites, cell wall structure component and physical structure, were summarized in this paper. Also, suggestions and prospects of further research were put forward on base of the summary.
