摘　　要：目的评估保安定超低容量喷洒对淡色库蚊和白纹伊蚊的现场灭效。方法 WHO推荐挂笼法和现场密度调查法,其中现场密度调查分别采用人帐诱捕法和CO2灯诱法对蚊虫进行诱集。结果挂笼实验中,有效剂量为98.5 g a.i/ha的保安定对淡色库蚊和白纹伊蚊的24 h灭效均达到100%。在分别采用帐诱和灯诱的现场密度调查中,淡色库蚊的平均密度下降率分别为83.68%和80.63%。结论保安定是一种较好的ULV喷洒剂,可以应用于紧急状况下病媒生物的控制。Objective To evaluate application of pirimiphos-methyl in space spray treatment for control Culex pipiens pallens and Aedes albopictus.Methods Two mosquito sampling criteria were used to determine the efficacy of the treatments：sentinel mosquito mortality and field adult mosquito.Results Average 24 h mortality for the Culex pipiens pallens and Aedes albopictus achieved 100%.The results of population investigation showed that the average density decline rate of Culex pipiens pallens in the field were 83.68% and 80.63% by mosquito net and CO2 baiting light respectively.Conclusion Pirimiphos-methyl is a good ULV spray and can be used for vector control in an emergency.
