草地贪夜蛾监测预警与防控研究进展

Research Progress in Monitoring and Early Warning,Prevention and Control of Spodoptera frugiperda

草地贪夜蛾Spodoptera frugiperda(J.E.Smith)是联合国粮农组织全球预警的重大跨境迁飞性害虫,具有寄主范围广、繁殖能力强、迁飞扩散快、为害程度重和防控难度大等特点。2019年1月首次入侵我国云南省,并在我国西南、华南及北方广大地区迅速蔓延扩散,对国家粮食安全构成严重威胁。随着草地贪夜蛾在我国周年繁殖区定殖成功,其"北迁南回"将成为常态,草地贪夜蛾已由入侵新发害虫转变为常发性害虫,其防控策略也将由应急防控转变为长期防控。面对严峻的防控形势,迁飞监测预警与科学防控是打赢草地贪夜蛾攻坚战的关键措施。综述了草地贪夜蛾在全球的分布与扩散、迁飞规律、防控技术与措施等,并提出了4个亟待突破的关键问题,以期为控制草地贪夜蛾在我国的传播为害提供参考。

The fall armyworm,Spodoptera frugiperda(J.E.Smith)(FAW),one of the major cross-border migration pests,displays characteristics of wide host range,strong reproductive capacity,fast dispersal speed by migration,serious damage and great difficulty in control.S.frugiperda was reported to invade Yunan,China in January 2019,and then rapidly colonized in southwest and south of China,and spread to northern area of China.S.frugiperda has posed a serious threat to food security of our country.As S.frugiperda colonized successfully in annual reproduction area of our country,it is normal that they spread to north in spring and move back to south in autumn.S.frugiperda is becoming common pest from new invasion pest,therefore,the control strategy will change from emergency prevention and control to long term prevention and control.Facing the serious control situation,migration monitoring and early warning and scientific control are the key measures to win the battle against the S.frugiperda.The global distribution and diffusion,migration pattern,technologies and measures of prevention and control of S.frugiperda are summarized.And four important problems which need urgent breakthrough are also proposed to provide references to control the spread and damage of S.frugiperda in China.
