| 摘 要： | 草地贪夜蛾Spodoptera frugiperda(Smith)是一种重要的经济作物害虫,在美洲玉米种植区均有发生。近几年该害虫迅速蔓延至非洲和东南亚等地区,并于2018年12月下旬在中国云南省被发现,对玉米生产造成严重威胁。化学农药和Bt作物是目前防治草地贪夜蛾的最主要手段,但大量研究表明,草地贪夜蛾已经形成了具有高抗药性和Bt抗性的种群。本文介绍了草地贪夜蛾抗药性和Bt抗性现状,从抗性相关因子的表达调控和靶标位点变异2个方面论述了草地贪夜蛾抗药性和Bt抗性机制,总结了目前草地贪夜蛾抗药性和Bt抗性的治理策略,并结合中国实际情况探讨了草地贪夜蛾综合防控的发展方向,以期为该害虫的防控提供参考。

| Abstract: | The fall armyworm Spodoptera frugiperda (Smith) is an important pest of major crops, which found in almost all the maize growing regions of America. In recent years, this pest has rapidly spread out in Africa and Southeast Asia, and has discovered in Yunnan Province of China on late December 2018, posing a serious threat to maize production. At present, insecticides and Bt crops are the most important measures to control S. frugiperda. However, many studies had shown that S. frugiperda have evolved highly resistant populations to insecticides and Bt toxins. In this paper, the current situation of resistance of S. frugiperda to insecticides and Bt toxins was introduced. The mechanism of resistance to insecticides and Bt toxins were described from both expression regulation of resistance-related factors and variation of target sites, and the main strategies for resistance management were summarized. The directions for development of integrated management strategies of S. frugiperda were also discussed in combination with the actual situation in China, expecting to provide a reference for the management of this pest. |
