Abstract:
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.
