摘　　要：为了筛选出对棉蚜高效的药剂品种,选用了11种常用杀虫剂对棉蚜进行了田间药效评价。结果表明:40%丙溴磷乳油、5.8%氟虫腈悬浮剂、20%啶虫脒可湿性粉剂具有较好的速效性,药后1 d的校正防效均大于86%;25%丁醚脲乳油、5%唑螨酯悬浮剂、240 g/L螺虫乙酯悬浮剂、50%吡蚜酮水分散粒剂、5.8%氟虫腈悬浮剂具有较好持效性,药后7 d的防效显著优于其他各处理。40%丙溴磷乳油、5.8%氟虫腈悬浮剂、20%啶虫脒可湿性粉剂与其他4种持效期较长药剂合理搭配使用可以有效防治棉蚜。The field control effect of eleven insecticides was studied aimed to screen the insecticides with high control effect to Aphis gossypii （Glover）.The results indicated that 40% Profenofos EC ,5.8% Fipronil SC ,20% Acetamiprid WP had good control effect to Aphis gossypii （Glover）, which control effects were more than 86% after 1 day,whereas 25% Diafenthiuron EC,5% Fenpyroximate SC,240g/L Spirotetramat SC,50% Pymetrezine WG and 5.8% Fipronil SC had good persistent effect, and their control effects after 7 days were significantly better than other treatments. 40% Profenofos EC ,5.8% Fipronil SC and 20% Acetamiprid WP with a reasonable use of the other four insecticides,which had good persistent effect to Aphis gossypii（ Glover ） ,could effectively control Aphis gossypii （ Glover ）.
