调查了新疆吐鲁番地区棉花苗期至吐絮期施药棉田和不施药棉田中棉蚜及其主要天敌发生动态，结合投影寻踪回归分析结果评价棉田中自然天敌对棉蚜的控制作用。结果表明，不施药棉田中草蛉和瓢虫对棉蚜有着良好的自然控制能力；施药棉田中常用的化学杀虫剂虽能短期控制棉蚜种群数量，但同时也严重杀伤了其天敌，不能达到长期控制蚜害虫的目的。

The population dynamics of Aphis gossypii Glover and its natural enemies were investigated in self-controlled and insecticide-controlled cotton fields in Turupan, Xinjiang during seedling - ball opening period of cotton, and the data were analyzed by project pursuit regression method. The results indicated that Coccinellidae and Chrysopidae as primary natural enemies of Aphis gossypii significantly reduced the aphid population in self-controlled cotton field. In the insecticide-controlled cotton field the insecticides not only caused a rapid reduction of the aphid population but also severely suppressed its natural enemies. It was concluded that using the conventional insecticide is not promising choice for effective aphid control.
