Progress for occurrence and management and the strategy of the fall army worm Spodoptera frugiperda (Smith).


Native to the subtropical and tropical regions of America, the fall armyworm Spodoptera frugiperda is a serious agricultural pest. S. frugiperda is hard to manage because it displays widely adaption to host plants and climate, strong reproductive capacity, fast dispersal speed, and serious sudden plant damage. Now, it was found in more than 100 countries in the world. In January, 11th, 2019, S. frugiperda was firstly found in China in Yunnan and expanded to more than 300 counties of 14 provinces of China in May, 21th, 2019. There is two strains of S. frugiperda i. e. corn strain and rice strain which have different host plant preference. Corn strain prefers to corn, cotton and sorghum, and rice strain prefers to rice and some grasses. Corn strain was confirmed, but rice strain was not found in China until now. S. frugiperda will be a major pest of corn, sugarcane and rice in South China since climate and rich host plants in this region are suitable for the pest. This paper reviewed the biology of S. frugiperda and current management technology. Base on the characteristics of cropping system in South China, we proposed suggestions on S. frugiperda management attempting to protect agricultural production safety.
