摘　　要：2019年,稻飞虱在我国南方稻区总体中等发生,呈现迁入期偏早,发生为害前重后轻、南重北轻的特点。分析认为,境外虫源基数和早期迁入量高、中后期气候条件总体不利、各地防控工作及时有力,是影响2019年稻飞虱发生为害程度的重要因素。提出了加强监测预警、实施分区治理、强化科学用药和优化稻田生境的对策建议。In 2019,rice planthopper occurred moderately in the rice regions in southern China,with the characteristics of early immigration,heavy occurrence in early stage and light later,heavy occurrence in the south and light in the north.This occurrence traits could be attributed to several interaction factors,such as a large amount of cross-border insect source and its early immigration,generally unfavorable climate in the middle and later stages,and timely prevention and control work in various regions.Management suggestions of rice planthoppers in China were put forward,such as strengthening monitoring and early warning,zoning management,scientific use of pesticides,and optimization of the rice field habitat.
