摘　　要：对安徽省3个不同地区竹林样地的虫草及虫生真菌进行了野外采集和调查,发现安徽省竹林中分布的虫草分别为多座线虫草(小蝉草)Ophiocordyecps sobolifera、大蝉草Cordyceps cicadae、拟细线虫草O.gracilioides、一种线虫草O.sp.;主要虫生真菌分别为蝉棒束孢Isaria cicadae、细脚棒束孢I.tenuipes、球孢白僵菌Beauveria bassiana、布氏白僵菌B.brongniartii、柱孢绿僵菌Metarhizium cylindrosporae。其中蝉棒束孢最多,在3个地区竹林中均占60%以上。竹林中主要寄主为蝉若虫,在3个地区竹林中均占80%以上。并且对竹林中蝉棒束孢的发生规律和发生周期进行了研究。The investigation on Ophiocordyceps and its allies in three different bamboo forests from Anhui province were studied. The result showed that there were four species of Ophiocordyceps and five species of entomogenous fungi as follows, Ophiocordyceps sobolifera Hill ex Watson, O. gracilioides Kobayasi, Cordyceps cicadae Shing, O. sp., Isaria cicadae Miq., L tenuipes Peck., Beauveria bassiana Balsamo, B. brongniartii Sacc., Metarhizium cylindrosporae Q. T. Chen ＆ H. L. Guo. L cicadae, of which, the most dominant species, comprised more than 60% in each bamboo forest. The main host was nymph of cicadidae with more than 80% of frequency in all sample plots. Meanwhile the occurrence rules and cycle of/. cicadae was explored.
