摘　　要：水稻黑条矮缩病 (RBSDV)是由传毒媒介灰飞虱Laodelphaxstriatellus (Fall n)传播所致 ,治虫防病是目前防治水稻黑条矮缩病的重要手段。生产实践证明 ,防治该病应以控制灰飞虱种群数量增长为首选目标 ,把带毒灰飞虱尽可能地扑灭在迁移到水稻秧苗进行传毒侵染之前。因此掌握防治适期 ,选用高效低毒农药 ,切断初次侵染来源 ,才能达到控制该病发生的目的。Rice black-streaked dwarf virus (RBSDV) is transmitted by the small brown rice planthopper Laodelphax striatellus. Controlling the population of this insect pest is the most efficient way to prevent epidemic of RBSDV. The suitable time for chemical control of the small brown rice planthopper is just before the virus-borne insects move to the rice seedling field. In this way the first virus-borne insects are managed in the early season and the virus can not spread by the insect widely.
