摘要
白背飞虱是水稻上的重要害虫,而且是近年来发生严重的南方水稻黑条矮缩病毒的唯一传播介体。为有效降低白背飞虱自身的危害及其传播的南方水稻黑条矮缩病的发生,在云南德宏开展了4种拌种剂防治白背飞虱的田间药效试验。在25%吡蚜酮WP、60%吡虫啉FSC、35%丁硫克百威DS及70%噻虫嗪WS中,35%丁硫克百威DS在拌种后31d对白背飞虱种群的防效仍高达93.6%,其他3种拌种剂的防效分别为75.0%、55.0%及49.3%。因此35%丁硫克百威DS是适合于当地防治白背飞虱的水稻拌种剂。
White-backed planthopper is one of the most serious rice insect pests and the only vector of Southern rice black-streaked dwarf virus（SRBSDV）which devastated rice in recent years.Control effect of four seed-coating insecticides against the planthopper in paddy field was tested in Dehong,Yunnan Province.The aim is to reduce the planthopper population and prevent occurrence of SRBSDV.Among the four seed-coating insecticides,25% pymetrozine WP,60%imidacloprid FSC,35% carbosulfan DS and 70%thiamethoxam WS,35% carbosulfan DS afforded the highest corrected control efficacy of 93.6% against the planthopper 31 days after coating treatment,while those of the other three insecticides were 75.0%、55.0% and 49.3%,respectively.The results suggest that 35% carbosulfan DS is the most effective seed-coating insecticide for control of the white-backed planthopper in Dehong,Yunnan Province.
