摘    要:选用3种生物农药对玉米螟进行田间药效试验,结果表明B t、阿维菌素和白僵菌均能达到较好的防治效果和持效性,收获期的田间防效分别达到80.8%、77.8%和73.2%,蛀孔减退率分别为79.4%、73.5%和73.2%,大喇叭口期是玉米螟的最佳防治时期。建议生产中应采用以生物防治为主,在玉米螟大发生时结合低浓度的化学防治的策略,保证玉米生产安全。

关 键 词:玉米螟  生物农药  防效

Abstract:Toxicity of three kinds biological insecticides to the larvae of Ostrinia furnacalis were conducted.in field.The results showed that the Bt,abamectin and Beauveria bassiana had excellent control effect and long persevered duration on preventing Ostrinia furnacalis.The control effects of Bt,abamectin and Beauveria bassiana were 80.8%,77.8%,75.9% and reduction rates of bore holes were 79.3%,73.5% and 73.1%,respectively.The optimal prevention period of Ostrinia furnacalis is big flare period of maize.Corn bore...
Keywords:Ostrinia furnacalis  Biological insecticide  Control effect
