中文摘要：
通过水稻田罩笼试验研究了白背飞虱起飞迁出与世代、田间成虫密度的关系以及降水对起飞的影响，采用系统田调查和长翅雌虫卵巢系统解剖分析了各代翅型分化、迁出与水稻生育期的关系以及各世代虫源性质。结果表明：（1）早中稻田白背飞虱起飞迁出以第2、3代为主，后期迁出较少；（2）白背飞虱起飞迁出数量与田间成虫密度有关；（3）降水影响白背飞虱的起飞；（4）白背飞虱各世代以长翅型为主，世代间翅型分化模式不同于褐飞虱，表现为“长—长—长”；（5）白背飞虱起飞与水稻生育期关系不大；（6）白背飞虱虫源性质分为基本迁入型、部分迁入滞留与部分迁出型、基本迁出型。
英文摘要： The takeoff behavior, wing dimorphism and population characteristics of the white backed planthopper Sogatella furcifera (Horváth) (WBPH) in different years, locations and generations were studied by field surveys, ovarian dissection and observation of captive insects. The main results were: (1) The majority of the second and third generations of WBPH are emigrants colonizing earlymid rice but, in 2009, the number of emigrants declined significantly after rice reaches the waxen maturity stage; (2) The number of emigrants was correlated with adult density; (3) heavy precipitation affects the number of insects that take to the air; (4) The ratio of the macropterous adults in most of the local generations was more than 80% and their wing forms were ‘macropterousmacropterousmacropterous’ in successive generations, a different pattern to that observed in the brown planthopper Nilaparvata lugens (Stl), (5) There was no relationship between the number of insects taking to the air, or otherwise emigrating, and rice growth stages; (6) The population characteristics of the WBPH could be classified into three types: mostly immigrants, partly local breeding and partly emigrated, and mostly emigrated.
