摘 要: | 自2018年,于王屋山地区发现栎树天牛虫害。该地区栎树为天然林建群种,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-7月,在海拔700-1700 m的虫害发生区,采用人工投放球孢白僵菌(Beauveria bassiana)粉的方法,进行天牛虫害防治。结果表明:1)栎旋木柄天牛的害虫数量明显多于双簇污天牛;2)球孢白僵菌对两种主要的天牛害虫均具有良好的防治效果;3)球孢白僵菌对栎旋木柄天牛的致死率高于双簇污天牛。

Prevention and Control of Oak Beetles in Wangwu Mountain Area of Jiyuan |
| |
Abstract: | Since 2018, oak beetle pests have been found in the Wangwu mountain area. The oaks in this area are natural forest species, covering a wide field, thus the threat of oak beetle pests is great. After investigation, it was determined that the species of 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 beetles in the pest occurrence area from June to July 2020. The results showed that 1) the number of Aphrodisium sauteri pests was obviously more than that of Moechotypa diphysis. 2) Beauveria bassiana had a good control effect on the two main oak beetle pests. 3) the lethal rate of Beauveria bassiana to Aphrodisium sauteri was higher than that of Moechotypa diphysis. |
