In addition, the monitoring also found that overseas grass moths continued to fly into yunnan and hainan and other places, resulting in internal and external insect attacks, pest control situation more severe.
It is reported that the large number of domestic and foreign sources of insects and the spread of maize fields to northern areas such as the Huanghuai Sea, treat corn cultivation more than 50%, estimated to affect the annual area of about 100 million mu.
