本文报道了云南省各食用菌栽培地眼蕈蚊科（Sciaridae）害虫共6属11种, 其中异迟眼蕈蚊Bradysia difformis Frey为中国新纪录种, 独刺普眼蕈蚊Cosmosciara perniciosa Edwards为中国新记录属和种, 并提供了云南省食用菌眼蕈蚊种类检索表。研究标本均保存于云南农业大学昆虫系标本室。根据各地标本采集数据对不同食用菌上眼蕈蚊种类优势度进行了分析, 结果表明平菇厉眼蕈蚊Lycoriella pleuroti Yang et Zhang和异迟眼蕈蚊B. difformis Frey为云南省食用菌上眼蕈蚊的主要优势种类。

Taxonomy and dominance analysis of sciarid fly species (Diptera: Sciaridae) on edible fungi in Yunnan

This paper reports the sciarid fly species on edible fungi of Yunnan province. Six genera and eleven species were identified, including one new record genus (Cosmosciara Frey), and two new record species (Bradysia difformis Frey and Cosmosciara perniciosa Edwards) in China. A key to the all species was given. All voucher specimens of the survey are deposited in the laboratory of Entomology Department, Yunnan Agricultural University. Analysis of the data of the sciarid fly species on different hosts indicated that Lycoriella pleuroti Yang et Zhang and B. difformis Frey were the dominant species on edible fungi in Yunnan.
