When two main types of migratory flight pests severely infest rice fields, what should we do?

As the temperature warms up in the spring, migratory flight pests such as the rice planthopper and rice leaf roller become active, migrating flight from south to north, causing outbreaks of these pests.
 
Eastern Asia is the main migratory flight destination for rice planthoppers, which mainly come from Southeast Asian countries such as Vietnam and Thailand. Rice planthoppers begin to migrate flight from central and northern Vietnam in March and April, gradually moving to southern China, the middle and lower reaches of the Yangtze River. 
When passing through Zhejiang and Jiangsu Province, some of them will migrate flight to Japan, while others go to South Korea. In early-stage, the migratory flight pests are the grey planthopper and the white-backed planthopper, while the brown planthopper migrates flight later.
 
It is recommended that growers pay attention to take measures to prevent and control pests, ensuring the safety of rice production.
