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

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.
