目的了解草原地区骆驼生活环境中蝇种及分布,探讨不同蝇种作为骆驼斯氏副柔线虫病传播媒介的可能性。方法2007-2009年的7-9月对3个荒漠化草原地区骆驼生活环境中的蝇种进行调查。用网捕法收集,并利用传统的形态学分类方法对其进行种属区分。结果经鉴定,共发现蝇类9科17属25种,在内蒙古地区为新记录的有12种。其中从内蒙古巴彦淖尔地区采集2489只,优势蝇种为迷隰蝇,占该地区采集总蝇数的37.2%,其次为截脉角蝇,占23.0%。从阿拉善地区采集2260只,所占比例最大的是扁蝇科的蝇种,约为31.5%,粪蝇科的小纹鬃粪蝇占26.5%,其它蝇种所占比例均较小。从乌兰察布地区采集2343只,其中锯翅蝇科的蝇种所占比例最大,为43.4%,其次为海滨溜蝇和吸溜蝇,分别为10.6%和12.4%。结论基本掌握了内蒙古地区骆驼生活环境中的蝇种组成,为斯氏副柔线虫传播媒介的调查确定提供了重要的基础数据。

Objective To determine the species and distribution of flies in the living environment of camels in the steppe region, in order to evaluate the possibility of different kinds of flies to be vectors of Parabronema skrjabini. Methods From July to September in 2007 to 2009, species of flies in three desertification grasslands where camels lived were investigated. Net fishing method was used to collect flies and traditional morphological classification to identify the species. Results As a result, 9 families, 17 genera and 25 species were identified in Inner Mongolia, 12 species of flies being new records. A total of 2489 flies were collected from Bayannaoer in Inner Mongolia, the dominant species being Hydrophoria ambigua, up to 37.2%, next, the proportion of Haematobia titillans was high, up to 23.0%. From the 2260 collection in Alaxan region, the dominant species, accounting for about 31.5%, consisted of Coelopidae, followed by Norellia striolata that accounted for 26.5%; the proportion of other fly species was relatively small. A total of 2343 flies were collected from Wulanchabu region. Trixoscelidae accounted for a dominant portion of about 43.4%, followed by Lispe litorea and L. consanguinea （10.6% and 12.4%, respectively）. Conclusion The composition of species of flies in camel＇ s living environment in Inner Mongolia was primarily uncovered, providing essential fundamental data for the investigation of Parabronemosis vectors.
