摘　　要：为评价古巴蝇(Lixophaga diatraeae Townsend)和赤眼蜂(Trichogramma chilonis)防治甘蔗螟虫的效果,在广西农科院武鸣里建基地进行了古巴蝇和赤眼蜂防治甘蔗螟虫大田示范。对冬植蔗、春植蔗、秋植蔗、宿根蔗和实生苗释放古巴蝇和赤眼蜂防治甘蔗螟虫的结果显示:在不施用农药防治甘蔗螟虫的情况下,仅适时释放古巴蝇和赤眼蜂到蔗地,各蔗地的枯心率和螟害节率平均在5%和10%以下。表明古巴蝇和赤眼蜂能有效控制螟虫为害,为在生产上推广应用这一生物防治技术提供了依据。The field demonstration was conducted to evaluate the control effect of sugarcane borers by releasing Lixophaga diatraeae and Trichogramma chilonis in Lijian site of Guangxi Academy of Agricultural Sciences in Wuming. Lixophaga diatraeae and Trichogramma chilonis were released to control sugarcane borers on winter planting, spring planting, autumn planting and ratoon sugarcane and seedling. The results showed that： after releasing and without use pesticides in sugarcane fields, the dead heart rate and the borer section rate were less than 5% and 10%, respectively. It may provide a basis for the application of biological control technology in production.
