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。
Cordyceps militaris and entomogenous fungi collected from bamboo forests in three different areas of Anhui Province were collected and surveyed. The results showed that Cordyceps cicadae (Cordyceps cicadae), Cordyceps cicadae , Cordyceps militaris O.gracilioides, a Cordyceps O.sp .; main entomogenous fungi were Cordyceps Cicadae Isaria cicadae, I. piniperda I.tenuipes, Beauveria bassiana Beauveria bassiana, Beauveria bbrongniartii, Metarhizium cylindrosporae. Among them, Cicadulospora sp. Was the most, accounting for more than 60% in all three regions. The main host in bamboo forest is cicada nymphs, accounting for more than 80% of all bamboo forests in the three regions. In addition, the occurrence regularity and period of Cicustemon in bamboo forest were studied.
