摘要: 亚洲玉米螟 Ostrinia furnacalis(Guenée)是云南省玉米上的主要害虫,在德宏州盈江县勐弄乡勐典村和苏典乡勐嘎村开展了释放玉米螟赤眼蜂Trichogramma ostriniae Pang et Chen防治亚洲玉米螟田间试验,结果表明,释放玉米螟赤眼蜂对亚洲玉米螟的田间防治效果显著,平均校正寄生率分别为74.27%和76.30%,被害株减退率分别为62.28%和66.50%,百秆活虫减退率71.76%和76.74%,虫孔减退率分别为63.83%和75.24%,平均防治效果分别为65.96%和72.82%;总平均挽回产量损失率7.79%,平均每公顷挽回经济损失420.06元,投入产出比1:1.47。

Abstract: The Asian corn borer (ACB), Ostrinia furnacalis (Guenée) is the main insect pest of corn in Dehong prefecture of Yunnan Province. Control effects on the pest by releasing Trichogramma ostriniae Pang et Chen were evaluated in corn fields of Mengdian Village, Mengnong Township and Menga Village, Sudian Township in Yingjiang County, Dehong Prefecture, Yunnan Province. ACB egg masses were parasitized by 74.27% and 76.30%, infested plants decreased by 62.28% and 66.50%, number of larvae and pupae per 100 plants reduced by 71.76% and 76.74%, and wormholes reduced by 63.83% and 75.24%, the average control efficacy was 65.96% and 72.82%, respectively. The corn yield loss was reduced by 7.79%, equaling a reduction of economic loss of 420.06 Yuan per hm2 and achieving an input-output ratio of 1:1.47.
