[Objective] The aim was to study the field efficacy of several insecticides on Aphis citricola van der Goot to provide reference for the control of Aphis citricola van der Goot.[Method] 8 pesticides were used for the investigation of the control effects against Aphis citricola van der Goot in field.[Result] There were significant differences on the control effect among the 8 tested pesticides.Among them,8 000 times liquid of 48％ thiamethoxam SC,4 000 times liquid of 22％ spirotetramat · thiamethoxam SC and 8 000 times liquid of 22％ clothianidin SC had excellent and quick control effect,with the control efficacy of more than 90％ at 1-14 days after treatment (DAT).22.4％ spirotetramat SC had poor fast-acting property with the controlling effect of less than 78％ at 1 DAT and 3 DAT,while it had good persistence with the control efficacy of 93.9％-97.2％ at 7-14 DAT.The controlling effect of 15 000 times liquid of 4.9％ afidopyropen DC were less than 78％ at 1 DAT,while it had good persistence with the control effect of more than 85％ at 3-14 DAT.The controlling effect of 10％ flunicotamid SC were less than 62％ at 1 DAT,and the controlling effect were more than 93％ at 3-7 DAT,and then the effect was decreased with time.3 300 times liquid of 10％ imidacloprid WP and 25 000 times liquid of 20％ acetamiprid SP had poor fast-acting property and persistence,the controlling effect were less than 78％ at 1 DAT,and less than 72％ at 10-14 DAT.[Conclusion] These results suggested that the rational applications of 8 000 times liquid of 48％ thiamethoxam SC,4 000 times liquid of 22％ spirotetramat · thiamethoxam SC and 8 000 times liquid of 22％ clothianidin SC could be recommended for controlling Aphis citricola van der Goot in apple production.%[目的]探讨8种不同类型杀虫剂对苹果黄蚜的防治效果,为苹果黄蚜的防治提供参考.[方法]通过田间小区试验比较了4.9％双丙环虫酯可分散液剂、10％氟啶虫酰胺悬浮剂、22％螺虫乙酯·噻虫啉悬浮剂、22.4％螺虫乙酯悬浮剂、480 g/L噻虫啉悬浮剂、22％氟啶虫胺腈悬浮剂、20％啶虫脒可溶性粉剂、10％吡虫啉可湿性粉剂8种药剂对苹果黄蚜的防治效果.[结果]8种药剂对苹果黄蚜的防治效果差异显著,其中48％噻虫啉悬浮剂8 000倍液、22％螺虫乙酯·噻虫啉悬浮剂4 000倍液和22％氟啶虫胺腈悬浮剂8 000倍液能有效控制苹果黄蚜危害,且速效作用好,持效期长达14 d,药后1～14 d对苹果黄蚜的防治效果均在90％以上;22.4％螺虫乙酯悬浮剂4 000倍液对苹果黄蚜速效性较差,药后1和3d的防治效果均低于78％,但持效性较显著,药后7～14 d的防治效果为93.9％ ～ 97.2％;4.9％双丙环虫酯可分散液剂15000倍液药后1d的防治效果低于78％,但其持效性较显著,药后3～14 d的防治效果均在85％以上;10％氟啶虫酰胺悬浮剂3 333倍液药后1d的防治效果低于62％,但药后3～7d的防治效果均在93％以上,之后防效逐渐递减.10％吡虫啉可湿性粉剂1 500倍液和20％啶虫脒可溶性粉剂2 500倍液对苹果黄蚜的防治效果速效性和持效性均较差,药后1d的防治效果低于78％,药后10～14 d的防治效果低于72％.[结论]在苹果安全生产中,建议轮换使用48％噻虫啉悬浮剂8 000倍液、22％螺虫乙酯·噻虫啉悬浮剂4 000倍液和22％氟啶虫胺腈悬浮剂8 000倍液防治苹果黄蚜.
