The Classification of the Gamasid Mite Communities on Rodentia and Insectivora in Guizhou Using Hierachical Analysis

本文应用系统聚类分析方法,对贵州省境内所获的21种啮齿目及食虫目动物体表革螨群落进行了初步分类。褐家鼠、黄胸鼠及小家鼠体表革螨群落为同一类型;大绒鼠与黑腹绒鼠为同一类型;大足鼠与黄毛鼠为同一类型;针毛鼠与社鼠为同一类型;黑线姬鼠与灰麝鼩为同一类型。结果提示,宿主体表革螨群落相似程度,与宿主的亲缘关系及所处生态环境有关。

We collected 21 species of Rodentia and Insectivora in Guizhou Province from 1978-1988. Using hierachical analysis which is an important method of numerical taxonomy, the gamasid mite communities on 21 hosts (R0dentia and Insectivora) were divided into seven types. The gamasid mite communities on Rattus norvegicus, Rottus flavipectus and Mus musculus were the same types, and their dominant species were Laelaps echidninus and Ornithonyssus bocoti; Eothenomys miletus and Eothenomys melanogoster were the same types, and their dominants were Loelaps ehini; Rattus nitidus and Rottus losea were the same types, and their dominants were Loelaps echidninus and Laelaps nuttalli: Niviventer fulvescens and Nioiventer confucianus were the same types, their dominants were Laelaps echidninus and Loelops turkestonicus: Apodemus agrorius and Crocidura attenuata were the same types, their dominants were Laelaps echidninus and Tricholaelaps myonyssognathus; Mus pahari and Rattus bowersi were independent types, the former's dominants were Laelaps guizhouensis and Loelaps paucisetosa, and the later was Laelaps turkestanicus. It is difficult for the gamasid mite communities on the rest hosts to be divided into certain types because the samples of hosts were too less
