Field Efficacy Test of Biological Insecticide on Ostrinia Furnacalis
摘要
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 borer control should take biological control as dominant means, assisted by low concentration chemical pesticides. It can provide guarantee for corn production safety.关键词
