中文摘要： 为探索玉米螟Ostrinia furnacalis Guenée生物防治新技术，春季应用白僵菌(Beauveria bassiana)封玉米秸秆垛加夏季田间释放松毛虫赤眼蜂Trichogramma dendrolimi Matsumura的方法，实施了大面积玉米螟生物防治技术。结果表明，利用白僵菌封垛加释放松毛虫赤眼蜂的复合技术防治玉米螟，平均防治效果达70.95%，挽回玉米产量损失率6.45%。这种复合生物防治技术减少了田间玉米螟成虫和幼虫的数量，延长了控制玉米螟的时间，可以根据玉米螟的发生情况和玉米生产的需要而应用。
英文摘要： A new bio-control method for the Asian corn borer (Acb) integrating the application of the parasitic fungus Beauveria bassiana to seal corn stalk mounds in spring with the release of the parasitic wasp Trichogramma dendrolimi Matsumura in summer, was used to control Acb in cornfields. The control effect of this method was 70.95% and it recovered 6.45% of the crop formerly lost to Acb. This integrated bio-control method reduces the number of Acb imago and larvae, and lengthens the duration of control of Acb in cornfields. It can be applied when required according to the degree Acb infestation and production needs.
