摘　　要：[目的]为筛选出适合我区防治苹果绵蚜的有效药剂,科学指导实际生产。[方法]2018年8月在林芝市巴宜区布久乡果园选用8种杀虫剂,按厂家推荐浓度进行稀释后,采用喷雾法进行药效试验。[结果]0.5%藜芦碱可溶液剂、22%阿维·毒死蜱微乳剂、0.6%烟碱·苦参碱乳油3种药剂在药后15 d防效仍达到80%以上,30%噻虫嗪悬浮剂防效也可达75%以上。[结论]这4种药剂均可作防治苹果绵蚜的首选药剂,可在实际生产中交替使用。[Aims] This study aims to screen out effective insecticides to control Wolly apple aphid for guiding practical production in Tibet. [Methods] In August of 2018, eight insecticides against Wolly apple aphid were tested at recommended concentration by using spray method in Bujiu Township Orchard, Bayi District, Linzhi City. [Results] The results of field trials showed that veratridine 0.5% SL, avermectin·chlorpyrifos 22% ME and nicotine·matrine 0.6% EC had better control effect with a control efficacy of more than 80% after 15 days, and the control effect of thiamethoxam30% SC could also reach more than 75%. [Conclusions] These four insecticides can be used as the first choice to control Wolly apple aphid, which can be used alternately in actual production.
