摘要
1993~1995年在太原、临猗等地进行了咪蚜胺、硫丹和丁硫克百威防治棉蚜田间药效试验。结果表明,这3种新农药对棉花苗期蚜虫均有良好的防治效果,尤以咪蚜胺和丁硫克百威的防效最为突出。在棉蚜发生盛期,25%咪蚜胺可湿性粉剂以2000倍液喷雾防治,2~14天的防效可达95%~100%,持效期在14大以上;20%丁硫克百威乳油以1000~2000倍液喷雾,1~5天的防效可达92%~100%。试验充分说明咪蚜胺的防效和持效,明显好于对照农药40%久效磷水剂,是理想的防治抗性棉蚜的替代药剂。
Field trials of imidacloprid, endosulfan, and carbosulfan against resiStant cotton aphid (Aphid gossypii) to pyrethroids and some carbamate and organophosphurous insecticides was made in different location of Shanxi, PR China. All three insecticides could effectively control the population increase of resistant cotton aphid. Controlling duration of one spraying of imidacloprid held more than 14 days with effective limitation of population growth, while carbosulfan and endosulfan for 7 days. But the 3 insecticides were better than the commonly used monocrotophos.Therefor, imidacloprid, endosulfan, and carbosulfan would be recommended as alternatives for resistant cotton aphid control in Shanxi.
