我国水稻迁飞性害虫猖獗成因及其治理对策建议

OUTBREAK ANALYSIS OF RICE MIGRATORY PESTS IN CHINA AND MANAGEMENT STRATEGIES RECOMMENDED

本文运用生态学的基本原理，在阐述我国稻飞虱（褐飞虱Ｎｉｌａｐａｒｖａｔａｌｕｇｅｎｓ（ｓｔａｌ），白背飞虱Ｓｏｇａｔｅｌｌａｆｕｒｃｉｆｅｒａ（Ｈｏｒｖａｔｈ））和稻纵卷叶螟（ＣｎａｐｈａｌｏｃｒｏｃｉｓｍｅｄｉｎａｌｉｓＧｕｅｎｅｅ）近１０—２０年来的发生和危害状况后，分析认为，我国水稻迁飞性害虫的猖獗力害，与初始主源、生产水平和作物坏境及气候异常有很密切的关系。本文还对未来若干年内的发生趋势作了浅析，同时从宏观治理的高度提出一些建没性的控制对策。

With ecological principals, the outbreak situations of rice migratory pests, (brownplant hopper Nilaparvata lugens (Stal ), white-backed planthopper Sogatella furcifera(Horvdth) and rice leaf-folder Cnaphalocrocis medinalis Guenee) in China, were analyzed. It isexpounded that the area and regions in which rice attacked by those pests have been expendedin recent 10 to 20 years and that the outbreaks have frequently taken place and the populationinfesting rice has gone up throughout the country since 1970' s.They were closely related with(1) the pests' fecundity conditions in immigrant sources,with (2) productive level of ricewhich provides the pests with an improved crop environment, and with (3) abnormal climaticevents and/or weather features such as warmer winter, stronger west pacific subtropical Highand El Nino phenomenon. Some strategies for overall management were recommended.
