摘　　要：研究旨在筛选有效的杀虫剂以控制设施番茄上的烟粉虱,并评估其对后期产量的影响。本研究选取6种杀虫剂,通过田间药效试验,对比了喷雾法对烟粉虱的防控效果。结果显示,供试药剂均对烟粉虱具有一定的防控效果,其中22.4%螺虫乙酯悬浮剂和22%氟啶虫胺腈悬浮剂表现出较优的防治效果,施药后7 d防效均达到84%以上。在增产效果方面,与对照组相比,上述2种杀虫剂处理的后期产量增产率超过30%。此外,这些药剂对作物生长和环境均无不良影响。因此,建议在生产实践中轮换使用这些有效药剂,以实现烟粉虱的有效防控。To screen the highly control insecticides against Bemisia tabaci of facility tomato,six insecticides were selected to test by spraying method in this study,and the control efficiency of different insecticides against Bemisia tabaci and yield of tomato were investigated and compared.The results showed that all the insecticides had the inhibitory effects against Bemisia tabaci,among which 22.4%spirotetramat SC and 22%sulfoxaflor SC exhibited the better control efficiency.After 7 days of application,their control efficiency exceeded 84%,which was 30%higher than the yield of CK.These two insecticides had no adverse impacts on crops and environment,which were suggested to be used alternately in production to achieve effective prevention and control purposes.
