摘　　要：2018年,王屋山地区发现栎树天牛虫害。栎树为该地区天然林的建群树种,覆盖面积广,天牛虫害威胁大。经勘察确定,主要危害栎树的天牛物种为双簇污天牛(Moechotypa diphysis)和栎旋木柄天牛(Aphrodisium sauteri)。本研究于2020年6月,在海拔700~1 700 m的虫害发生区,采用人工投放球孢白僵菌(Beauveria bassiana)粉炮的方法进行天牛虫害防治。结果表明,栎旋木柄天牛的害虫数量明显多于双簇污天牛,球孢白僵菌对该2种主要的天牛虫害均具有良好的防治效果,且球孢白僵菌对栎旋木柄天牛的致死率高于双簇污天牛。In 2018,oak longicorn beetles was found in the Wangwu Mountain area.The oaks are natural forest constructive tree species in this area,with a wide coverage,the threat of oak longicorn beetles is great.After investigation,it was determined that the species of longicorn beetles that mainly endanger oaks were Moechotypa diphysis and Aphrodisium sauteri.In this study,we used the method of artificially placing Beauveria bassiana powder to control oak longicorn beetles in the pest occurrence area(altitude700-1700 m)in June 2020.The results showed that the number of Aphrodisium sauteri was obviously more than that of Moechotypa diphysis,Beauveria bassiana had a good control effect on the two main oak longicorn beetles,the lethal rate of Beauveria bassiana to Aphrodisium sauteri was higher than that of Moechotypa diphysis.
