被毛孢属两个昆虫病原真菌的重新描述

摘要

[Objective] We studied resources,diversity and taxonomic information of the genus Hirsutella.[Methods] We identified two fungal samples GZUIFR-djl4 and GZUIFR-dyl from Guizhou Province,which parasitized adult of Cercopidae (Homoptera) and Dioryctria splendidella (Lepidoptera) through morphological characteristics and phylogenic analyses based on tef1,ITS and 28S rDNA sequences.[Results] The two fungi were identified as Hirsutella changbeisanensis and Hirsutella leizhouensis.[Conclusion] Two new fungal isolates were studied with their information of hosts,habitats,molecular sequences and phylogenetics.%[目的]调查研究被毛孢属真菌资源,丰富该属的物种多样性,完善已知种在公共数据库中的分类信息.[方法]从贵州省发现两个分别寄生于同翅目沫蝉、鳞翅目松梢螟成虫的真菌标本GZUIFR-dj 14和GZUIFR-dyl,通过形态学观察和基于tef1、ITS和28S rDNA 3个基因序列的分子生物学系统发育分析对其进行鉴定.[结果]两个病原真菌被鉴定为两个已知种,分别为长白山被毛孢(Hirsutella changbeisanensis)和雷州被毛孢(Hirsutella leizhouensis).[结论]重新描述了这两种被毛孢的标本和无性型分离菌株,对其新寄主、新栖息地进行了报道,并补充了分子序列、系统发育分析等分类信息.
