在1990 - 2008年的调查中，我们从中国西南部云南省的28个县捕获了4，113只亚洲家鼠，Rattus tanezumi Temminck 1844（啮齿目：鼠科）。从这些大鼠中，共收集到19，304只革螨（阿卡里：中气门目），并鉴定为包括50个不同的种。革螨的物种多样性，从这个单一的鼠种是高于以前报道的多个主机在给定的地理区域内。在50种螨中，31种为体外寄生螨，19种为自由生活螨。野外捕获的鼠类体内螨类的物种多样性明显高于室内捕获的鼠类。从负二项分布的参数K被用来衡量的优势螨种的空间分布格局，并透露，所有的螨有聚集分布的大鼠主机。大多数螨种主要表现出女性偏见的人口结构，女性比男性多得多。
During a survey lasting from 1990 to 2008, we captured 4,113 Asian house rats, Rattus tanezumi Temminck 1844 (Rodentia: Muridae) from 28 counties of Yunnan Province in southwestern China. From these rats, a total of 19,304 gamasid mites (Acari: Mesostigmata) were collected and identified as comprising 50 different species. The species diversity of gamasid mites from this single rat species is higher than that reported previously from multiple hosts within a given geographical region. Of the 50 mite species, 31 species belonged to ectoparasites and 19 species belonged to free-living mites. The species diversity of the mites from rats trapped outdoors was much higher than from rats trapped indoors. The parameter K from the negative binomial distribution was used to measure the spatial distribution patterns of the dominant mite species and revealed that all the mites had an aggregated distribution among the rat hosts. Most mite species showed a predominantly female-biased population structure with many more females than males.
