螟黄赤眼蜂防治水稻二化螟效果试验

摘要

In order to prevent and control rice stem borer in rice production, the comparison method was adopted to figure out the application effect of Trichogramma on Chilo suppressalis. The test results show that the wasps parasitic rate and the field control effect on rice stem borer eggs are both good, and the harm by the larvae of Chilo suppressalis was restrained to a certain degree, indicating that it is an effective biological measure to control Chilo suppressalis.%为防治水稻生产中的二化螟虫害，采用对比试验的方法，探讨应用赤眼蜂防治二化螟的效果。试验结果表明：螟黄赤眼蜂对田间二化螟卵的寄生率和防治效果均较好，且对二化螟幼虫的危害具有一定的控制作用，是稻田生产上防治二化螟的有效生物措施。
