Abstract:

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.
