On 24 May, 2019, the Ministry of Agriculture and Rural Affairs of China (MARA) held a video working conference for arranging prevention and control of fall armyworm (Spodoptera frugiperda), requiring that the ratio of damages and losses should be controlled below 5% and there should be no disaster involving large continuous areas.
Since its first migration from Southeast Asia to Southwest China in January 2019, fall armyworms have spread to 14 provinces and regions of China so far, Henan and Anhui provinces in central part of the country at the furthest. Right now, it has become an urgent need to effectively control the pests, which requires huge efforts.
0.13 million ha confirmed to be infested already
Featured by strong propagation capacity and rapid migration, fall armyworms are native to tropical and subtropical areas in America. Causing damage to many kinds of agricultural crops, these pests are a severe corn migratory pest.
In January 2019, fall armyworms were first found in Yunnan Province located in Southwest China and have migrated to 528 cities, counties and districts of 14 provinces and regions in the country.
It’s estimated that fall armyworms would arrive in the key planting area of spring corn in Northeast China this July. In the future, they will become another species of pest causing serious damage to China in conventional years.
Experts said that last year in Africa fall armyworms had caused economic losses as high as USD1 billion~USD3 billion and damaged corn planting areas taking up 5%~6% of the total cultivation areas of the crop. In July 2018, the pests were first found in Asia. The Food and Agriculture Organization of the United Nations (FAO) published a global warning for the pests one month later.
