茶尺蠖生物防治技术研究及无锡地区防治建议

Biological control of Ectropis obliqua and suggestions for its prevention and control in Wuxi

主要从天敌资源、信息化合物和微生物源农药三个方面对茶尺蠖生物防治技术进行概总结概括,重点对茶尺蠖核型多角体病毒制剂的使用技术及无锡地区使用方法进行介绍,病毒制剂对低龄期幼虫防治效果较好,虫口密度较大时也可与植物源农药混用施用。

In this paper,the biological control of Ectropis oblique was summarized,including natural enemy resources,pheromones and microbial pesticides.The application of Ectropis oblique nucleopolyhedrovirus(Eo NPV)in control pests in Wuxi City was reviewed.In the early larval stage,Eo NPV has good control effect.However,the mixture of Eo NPV and botanical pesticides can be used when the pest population density is large.
