Abstract:

　　【Abstract】　Objective　To illustrate the similarity， transitional tendency and classification of gamasid mite communities in the surrounding areas of Biluoxueshan in Weixi county of Yunnan province. Methods 　System clustering analysis was used in this study. Results　In 1560 small mammals captured， the dominant species of mites from Apodemus draco， Eothenomys miletus， Niviventer confucianus， Ap.chevrieri, Ap.peninsulae, Rattus norvegicus and R.tanezumi were Laelaps jingdongensis（Dr＝41.32）, L.chin（Dr＝41.87）,  L.traubi （Dr＝63.51） and L.turkestanicus （Dr＝24.78）, L.traubi（Dr＝18.82）,  Eulaelaps huzhuensis（Dr＝14.11） and L.chin（Dr＝11.76）, E.huzhuensis（Dr＝25.00）, E.huzhuensis（Dr＝23.61） and Haemogamasus oliviformis（Dr＝16.67）, Ornithonyssus bacoti（Dr＝71.73） and O.bacoti（Dr＝98.82）, respectively. The result of system clustering analysis indicated that there was prominent similarity between the gamasid mite from R.norvegicus and R.tanezumi, secondly it was the similarity among the mites from Ap.draco, Ap.peninsulae and Ap.chevrieri. Conclusion  The taxonomic relations of mite hosts was nearer, the communities similarity of gamasid mite was higher. The habits distribution of hosts had an effect on communities type of parasitic gamasid mite.
