Sogatella furcifera

The WBPH species has a large ecological and economic impact on China and immediate countries. S. furcifera can damage rice directly by feeding on the rice or indirectly by transmitting plant viruses such as southern rice black-streaked dwarf virus (SRBSDV).^[3]

S. furcifera can also cause unexpected damage to local rice crops due to their ability to annually migrate long distances.^[3]

Sogatella furcifera is a migratory pest of rice in Asia,^[2] migrating from tropical and subtropical regions toward northern or northeast Asia in spring and summer. At the end of growing season in autumn, their offspring migrate back to their southern overwintering sites.^[4]

In the 1970s and 1980s, a study of the WBPH was conducted. The study concluded that spring immigrants were from the Indochina Peninsula, and that they migrated into southern China. The WBPH that migrated to China continue to move toward northern China on prevailing winds.^[4]

Later trajectory analyses and migration simulations indicate that the East Asian populations of WBPH overwinter in Vietnam and southern Hainan Province, and in spring migrate to eastern China, Japan, and Korea, then migrate back in autumn.^[3]
