白僵菌[Beauveria bassiana (Bals.)Vuill.]是一种重要的虫生真菌,我国广泛用于防治玉米螟和松毛虫等农、林害虫。但关于自然界昆虫白僵病的发生特点和寄主范围等在国内报道很少,对于白僵菌的分类也比较混乱,有人认为B.globulifera应区别于白僵菌(B.bassiana)作为一个独立的种存在,但有人则认为B.globulifera应是白僵菌(B.bassiana)的异名,不能作为一个独立的种。作者在虫生真菌的采集调查中,从1962年冬至1965年夏共分离到白僵菌属真菌55个菌株。根据对这些菌株的研究,同意后一种的看法。 现将调查和鉴定结果报道如下。
Beauveria bassiana (Bals.) Vuill. Is an important entomogenous fungus, and is widely used in our country to control pests such as corn borer and pine caterpillars. However, there are few reports on the occurrence and host range of white stiff disease in nature and the classification of Beauveria bassiana. Some people think that B.globulifera should be distinguished from B. bassiana as an independent However, some people think that B.globulifera should be the synonym of B. bassiana and can not be regarded as an independent species. In the survey of collection of fungi, 55 strains of Beauveria were isolated from the winter of 1962 to the summer of 1965. According to the study of these strains, agree with the latter view. Now the investigation and identification results are reported below.
