中文摘要：
草地贪夜蛾 Spodoptera frugiperda (Smith)是一种原产于美洲热带和亚热带地区的跨境迁飞性重大害虫，具有寄主范围广、繁殖能力强、迁飞扩散快、危害程度重和防控难度大的特点。草地贪夜蛾自2019年1月入侵我国云南省并在西南地区迅速定殖、蔓延，5月中旬进一步迁飞扩散至长江和江淮流域。预计6-7月份可能继续北迁至黄淮海夏玉米产区和北方春玉米产区，将严重威胁我国玉米生产安全。本文综述了草地贪夜蛾的生物学特性、在非洲和亚洲地区的暴发原因、发展趋势、防控措施，并提出了应对策略，以期为控制草地贪夜蛾在我国的传播为害提供参考
英文摘要：
Fall
armyworm, Spodoptera frugiperda (Smith),
is a major transboundary migratory pest native to tropical and subtropical
areas of the Americas which displays
characteristics of wide host range, strong reproductive capacity, fast
dispersal speed by migration, serious damage and difficult-to-control. S. frugiperda was reported to invade
Yunan, China in January 2019, and then rapidly colonized and spread in
southwest China and other regions. In mid-May, S. frugiperda further migrate and spread to Yangtze River and
Yangtze-Huaihe River valley. It is predicted that S. frugiperda could reach the Huang-Huai- Hai Summer Corn Region
and the North Spring Corn Region, threating the safety of corn production in
China. This review summarized the biologicalcharacteristics,
outbreak reasons of S. frugiperda in
Africa and Asian, spread trends and control measures. We also proposed coping
strategies to provide references to control the spread and damage of S. frugiperda in China.
