摘　　要：2006年,在新疆阿克苏市进行了利用麦蛾柔茧蜂Habrobracon hebetor Say防治麦田第一代棉铃虫和棉田第二代棉铃虫的田间试验。结果显示,在麦田按500头/亩的量释放麦蛾柔茧蜂,可使麦田棉铃虫幼虫的虫口减退57．7%;化蛹量较对照减少0．56头/m^2。在棉田按700头/亩的量释放麦蛾茧蜂,对棉铃虫幼虫的麻痹率是50．73%,对棉铃虫的防效达65．96%。Field trials to control the cotton bollworm, Helicoverpa armigera in the first generation （in wheat field） and the second generation （in cotton field） by releasing the parasitoid, Habrobracon hebetor was established in Akesu, Xinjiang province in 2006. The results showed that the mortality of the H. armigera larvae was 57.7% and the pupal density was decreased by 0. 56 pupae/m^2 when compared to the control with the release of 500 H. hebetor per 667m^2 in wheat field. The percentage of paralysed larvae was 50. 73% , and the efficiency of the parasitold in controlling the insect was 65.95% with the release of 700 H. hebetor per 667m^2 in the cotton field.
