中文摘要：
为了研究双峰驼Camelus bactrianus斯氏副柔线虫病传播媒介——吸血蝇的分布,对内蒙古阿拉善盟、乌兰察布市和巴彦淖尔市3个双峰驼主产区的蝇类进行了网捕,对捕捉到的7 153只蝇进行了形态学鉴定,共鉴定出9科17属25种,其中3种为吸血蝇,即西方角蝇Haematobia irritans、截脉角蝇H.titillans和厩螫蝇Stomoxys calcitrans;比较分析了3个地区双峰驼生活环境的优势蝇种、蝇种多样性指标及相似程度,发现3个地区的优势蝇种各不相同：蝇种丰富度指数以巴彦淖尔市最高;物种多样性指数和均匀度指数均较低,以阿拉善盟最高、巴彦淖尔市最低;阿拉善盟蝇种与其他2个地区极不相似,巴彦淖尔市蝇种与乌兰察布市中等不相似。
英文摘要：
In order to study the distribution of Parabronema skrjabini in Camelus bactrianus in China,7 153 flies were netted from the main producing areas of C. bactrianus（ Alxa,Ulanqab and Bayannur） in Inner Mongolia. A total of 25 fly species belonging to 17 genera and 9 families were identified,while 3 species（ Haematobia irritans,H. titillans and Stomoxys calcitrans） were identified as sucking flies. Subsequently,the preponderant fly species,species diversity indices and similarity degree of the 3 live environment of C. bactrianus were analyzed. The results showed that the preponderant fly species among the 3 areas were very different; the fly species richness index of Bayannur was the highest; the diversity index and evenness index of the 3 areas were all low,but Alxa was the highest,followed by Ulanqab and Bayannur; the similarity degrees among Alxa and the other 2 were extremely different,and the index between Ulanqab and Bayannur was moderate different.
