Abstract: Objective:To study the structure of chigger mite communities of the rodents in Dongling Mountain,western Beijing.Method:A series of ecological methods are involved in this paper of community structure,diversity and similarity.Results:7 species of chigger mite,1780 individuals were collected in three different ecological habitats from June 1998 to May 1999 in the region.In forest habitat,the dominant species of those communities are not very outstanding,while in the habitats of shrub and farmland,they quite outstanding.In chigger mite communities,Leototrombidium orientale are dominant species for all hosts.ConclusionThe structures of chigger mite are simple,with low diversity indices.
