摘要: 目的:了解北京东灵山地区鼠类体外寄生虫种类和数量分布情况。方法:1998年6月至1999年5月在该地区的3类生境按常规方法共捕获鼠类7种568只,采集体外寄生虫48种3859只,其中蚤类16种582只,蜱类3种416只,革螨22种1081只,恙螨7种1780只。结果:3类生境鼠类体外寄生虫群落中低度物种(个体数<11)数多,约占总物种数的58%~88%,中度物种(个体数在11~100之间)少,较富集物种(个体数>100)更少。结论:鼠类体外各寄生虫群落物种丰富度和多度随宿主动物种类不同而变化较大。

Abstract: Objective:To understand species-abundance distribution of the rodent's ectoparasite communities in Dongling Mountain,Western Beijing.Methods:Wild rodents were captured by snap-traps in three different ecological habitats in the region from June 1998 to May 1999.7 species of rodents,568 individuals were examined for ectoparasites,16 species of flea,3 species of tick,22 species of gamasid mite,and 7 species of chigger mite collected.Results:The species of ectoparasites with individuals below 10 accounted for 58%-88%,the species with middle individuals(11-100) were generally scarce,and a few species with high abundance(>100) could be seen in the ectoparasites communities.Conclusion:Species richness and abundance indices varied significantly in different types of ectoparasite communities among different hosts.
