摘要
小绿叶蝉是茶树的重要害虫,主要以化学农药防治。本研究表明,利用800万孢子/ml 球孢白僵菌防治小绿叶蝉,死亡率达85%以上,圆孢虫疫霉,在相对湿度80%以上和虫口密度大时流行,寄生率较高,亦可应用于控制茶园小绿叶蝉。
Empoasca flavescens(Fabricius)is a mortal pest of tea,farm chemi-cals are usually used in the control.This article indicates the methodof using Beauveria bassiana in the control of Empoasca flavescens.Whenusing 8 millions bacillus/ml,the percentage of death covers ordinarilyover 85%.When eryniaradicans attends over HR 80% and grows duringlarge population,the parasitic rate is higer,producing the same effectto the control of the Empoasca flavescens in the tea plantation.
