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。
為瞭篩選齣對棉蚜高效的藥劑品種，選用瞭11種常用殺蟲劑對棉蚜進行瞭田間藥效評價。結果錶明：40%丙溴燐乳油、5.8%氟蟲腈懸浮劑、20%啶蟲脒可濕性粉劑具有較好的速效性，藥後1 d的校正防效均大于86%；25%丁醚脲乳油、5%唑螨酯懸浮劑、240 g/L螺蟲乙酯懸浮劑、50%吡蚜酮水分散粒劑、5.8%氟蟲腈懸浮劑具有較好持效性，藥後7 d的防效顯著優于其他各處理。40%丙溴燐乳油、5.8%氟蟲腈懸浮劑、20%啶蟲脒可濕性粉劑與其他4種持效期較長藥劑閤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%Pymetrozine 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).
