摘　　要：广西农垦北部湾总场2015~2016年2年连片分别实施2000 hm^2以上释放赤眼蜂防治甘蔗螟虫,2年来,取得了螟虫为害枯心苗率平均下降48.51%、螟害节率下降51.26%、死尾率下降51.56%、原料蔗单产增加21.77 t/hm^2、蔗糖分增加1.83个百分点的良好效果。本文报道了赤眼蜂防螟虫效果,分析了影响赤眼蜂防治螟虫效果的主要因素及提高防效方略。To study the control effect and influence factor on Mass-release of Trichogramma chilonis on Sugarcane borers, some experiments were conducted in Beibu Gulf, Guangxi Province in 2015 and 2016. The experimental test area was more than 2000 hm2 and the results showed that the dead heart rate fell by 48.51% and the rates of bored internodes and dead tail fell by 51.26% and 51.56%, respectively; the final average yield increased by 21.77 t/hm2 and cane sugar by 1.83%. The effect of Trichogramma chilonis to control borers was reported, and the main influencing factors and relevant improving measures were analyzed.
