中文摘要：

在皖东琅琊山自然保护区设置的20个样方中共采集672份虫生真菌标本,分属于4科8属20种.优势种依次为球孢白僵菌、粉拟青霉、环链拟青霉、布氏白僵菌和玫烟色拟青霉,其中球孢白僵菌占绝对优势,相对多度高达73.8%.选用物种多度、Shannon-Wiener指数H′和Pielou均匀度E对琅琊山虫生真菌物种多样性和季节分布进行研究发现,虫生真菌数量丰富但物种多样性指数较低;夏季虫生真菌菌株最为丰富,均匀度相对较低,随着气温及降雨量的下降,菌株数量急剧下降,均匀度相对较高;不同季节白僵菌属的数量波动大,但拟青霉属波动较小.

英文摘要：

672 specimens of entomogenous fungi belonging to 20 species, 8 genera and 4 families were collected from 20 sampling quadrates in the Langya Mountains Nature Reserve of East Anhui. The dominant species were Beauveria bassiana, Paecilomyces farinosus, P. cateinannulatus, B. brongniartii and P. fumosoroseus, and B. bassiana was most dominant, with the relative abundance of 73.8%. The entomogenous fungi in the Reserve were high in amount but low in diversity. The amount of isolates and the abundance of each species were the highest in summer and decreased with decreasing air temperature and rainfall, while the Pielou evenness changed from relatively low to relatively high. Paecilomyces spp. had a less seasonal fluctuation of quantity than Beauveria spp.
