Abstract: Objective:To study the structure of gamasid mite communities of the rodents in Dongling Mountain,Western Beijing.Methods:22 species of gamasid mite,1 081 individuals were collected in three different ecological habitats from June 1998 to May 1999 in the region.A series of ecological methods were study in this study of community structure,diversity and similarity.Result:In forest habitat,the dominant species of those communities are not very outstanding,while in the habitats of scrub and farmland,they are quite outstanding.In gamasid mite communities,Laelaps micromydisis dominant species for Apodemus agrarius and Clethrionmys rufocanus,Eulaelaps stabularis for for Rattus niviventer,E.dongfangis for Cricetulus triton.Conclusions:The structures of gamasid mite communities are complicated,with high diversity indices.
