摘　　要：为了评价在黄淮海夏玉米区释放米蛾卵繁育的玉米螟赤眼蜂Trichogramma ostriniae防治亚洲玉米螟Ostrinia furnacalis的可行性,本试验在室内组建了玉米螟赤眼蜂在亚洲玉米螟卵上的实验种群生命表的基础上,在河南省鹤壁市滑县测定了玉米螟赤眼蜂对亚洲玉米螟的防治效果,筛选出了具有较好防治效果的释放密度和释放方法。结果显示,米蛾卵繁育的玉米螟赤眼蜂在亚洲玉米螟卵上的净生殖力R0为9.8240,单雌平均产雌率R0'为12.6256,2013年在河南省鹤壁市滑县释放玉米螟赤眼蜂能使亚洲玉米螟虫口密度减退73.91%,释放密度为2.25×105头/hm2。2014年在鹤壁市淇滨区钜桥镇采用传统的人工挂卡和新型的无人机释放玉米螟赤眼蜂,亚洲玉米螟虫口密度减退54.55%-68.16%。结果表明,在黄淮海夏玉米区释放米蛾卵繁育的玉米螟赤眼蜂防治玉米螟是可行的。In order to evaluate the possibilities for controlling the Asian corn borer,Ostrinia furnacalis（ Guenée）,by releasing Trichogramma ostriniae Pang et Chen reared on Corcyra cephaloniae eggs in Huang-Huai-Hai summer corn region,life table of the experimental population of T. ostriniae on O.furnacalis eggs was constructed in laboratory. Then control efficacy of release Trichogramma for corn borers,was evaluated, and furthermore the densities and methods for Trichogramma releasing were assessed. Results showed that R0 and R0＇ of T. ostriniae reared on C. cephaloniae eggs was 9. 8240,12. 6256. In 2013,the decrease rate of O. furnacalis larva of summer corn in Huaxian county of Hebi was73. 91% by releasing T. ostriniae. In 2014, the decrease rates of O. furnacalis larvae were 54. 55%-68. 16% with release density of 2. 25 × 105 head / hm2,by using the traditional hanging up card by hand and new unmanned aerial vehicle release method in Juqiao town, Qibing district Hebi city. The results indicated that it is possible to release T. ostriniae reared on C. cephaloniae eggs to control O. furnacalis in Huang-Huai-Hai summer corn region.
