摘要：利用白蛾周氏啮小蜂对美国白蛾进行生物防治 ,取得了较好效果。在连续对 4代美国白蛾进行放蜂的防治区 ,美国白蛾的危害下降 ,而对照区美国白蛾仍造成一定的危害。放蜂区白蛾周氏啮小蜂对美国白蛾蛹期的寄生率经 2a的防治后达到 5 0 %～ 70 % ,同时由于没有施用化学农药 ,保护了其它天敌 ,各种天敌昆虫的总寄生率达到 83 2 6 %～ 95 82 %。应用灰色数学中关联度的计算方法 ,表明人工释放的白蛾周氏啮小蜂是生物控制美国白蛾的主要因子 ,但几乎不影响其它天敌昆虫对美国白蛾的寄生。
Hyphantria cunea were effectively controlled by using Chouioia cunea as a major biological control agent. In parasitic wasp successively released areas where 4 consecutive generations of H. cunea were studied, the damage caused by Fall Webworm decreased but in control areas the damage had no change. The parasitism rates in pupae of Fall Webworm caused by C. cunea reached to 50%～70% after 2 years of Control effort. Because of no pesticide used in these areas, Where almost all the natural enemies were protected, overall parasitism rates of all parasitic insects in pupae of Fall Webworm reached to 83 26%～ 95 82%. The results obtained by calculating the relational grade among parasitism rates of different insect natural enemies showed that C. cunea released by man was the major factor in biological control of the Fall Webworm and had little influence on other insect natural enemies. The damage caused by Fall Webworm was effectively reduced by all of natural enemies acting together.
