被毛孢属两个昆虫病原真菌的重新描述

Re-description of two entomopathogenic fungi in Hirsutella Pat.

【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-dj14和GZUIFR-dy1,通过形态学观察和基于tef1、ITS和28S r DNA 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。

[Objective] We studied resources, diversity and taxonomic information of the genus Hirsutella. [Methods] We identified two fungal samples GZUIFR-dj14 and GZUIFR-dy1 from Guizhou Province, which parasitized adult of Cercopidae（Homoptera） and Dioryctria splendidella（Lepidoptera） through morphological characteristics and phylogenic analyses based on tef1, ITS and 28 S r DNA 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.
