为了解贵州大绒鼠体表寄生虫的感染状况，以及为相关生物学研究奠定基础，于2013年7—8月选取贵州省都匀、龙里、贵阳、安顺、织金5个县（市）进行了大绒鼠体表寄生虫调查分析。结果表明：在贵州5个县（市）共捕获到大绒鼠185只，其中175只感染体表寄生虫，感染率高达94．6％；采集到体表寄生虫62种，包括17种恙螨、33种革螨、3种吸虱和9种蚤。密点纤恙螨为优势恙螨种，占恙螨总数的38．3％；金氏厉螨为优势革螨种，占革螨总数的93．3％；缺齿甲胁虱为优势吸虱种，占吸虱总数的96．3％；宽突栉眼蚤为优势蚤种，占蚤总数的35．0％。恙螨、吸虱、蚤的数量和物种数雌雄大绒鼠间差异无统计学意义；雄性大绒鼠体表的革螨感染率（97．96％）、种类数（30种）和个体数量（2339只）均显著高于雌性大绒鼠。恙螨的物种数和个体数与大绒鼠体重呈轻度负相关；革螨、吸虱、蚤类的物种数和个体数与大绒鼠体重、体长间的相关系数均无统计学意义。
為瞭解貴州大絨鼠體錶寄生蟲的感染狀況，以及為相關生物學研究奠定基礎，于2013年7—8月選取貴州省都勻、龍裏、貴暘、安順、織金5箇縣（市）進行瞭大絨鼠體錶寄生蟲調查分析。結果錶明：在貴州5箇縣（市）共捕穫到大絨鼠185隻，其中175隻感染體錶寄生蟲，感染率高達94．6％；採集到體錶寄生蟲62種，包括17種恙螨、33種革螨、3種吸虱和9種蚤。密點纖恙螨為優勢恙螨種，佔恙螨總數的38．3％；金氏厲螨為優勢革螨種，佔革螨總數的93．3％；缺齒甲脅虱為優勢吸虱種，佔吸虱總數的96．3％；寬突櫛眼蚤為優勢蚤種，佔蚤總數的35．0％。恙螨、吸虱、蚤的數量和物種數雌雄大絨鼠間差異無統計學意義；雄性大絨鼠體錶的革螨感染率（97．96％）、種類數（30種）和箇體數量（2339隻）均顯著高于雌性大絨鼠。恙螨的物種數和箇體數與大絨鼠體重呈輕度負相關；革螨、吸虱、蚤類的物種數和箇體數與大絨鼠體重、體長間的相關繫數均無統計學意義。

To understand the infestation and related biological issues of ectoparasites on the body surface of E.miletus in some places of Guizhou,an investigation was conducted on E.miletus captured in five counties from July to August in 2013,including Duyun,Longli,Guiyang,Anshun and Zhijin. Results:A total of 185 individuals were captured from the five counties of Guizhou.Of these 185 voles, 175 were infested with ectoparasites and the infestation rate reached 94.6%.A total of 62 ectoparasite species,including 17 species of chigger mites,33 species of gamasid mites,three species of sucking lice and nine species of fleas were collected from E.miletus.Leptotrombidium densipunctatum (38.3%),Laelaps chini (93.3%),Hoplopleura edentula (96.3%)and Ctenophthalmus axiproj ectus (35.0%)were the most predominant species of chigger mites,gamasid mites,sucking lice and fleas,respectively.Species number and individuals of three categories of ectoparasites(chigger mites ,sucking lice and fleas )had no significant difference between the male and female hosts(E.miletus).The gamasid mites infestation rate(97.96%), species number(30 species)and individuals(2 339 individuals)on the male host voles were significantly higher than that of the females(P < 0.05).Correlation analysis showed that a slightly negative linear correlation coexists between the chigger mite infestation(species number and individuals )and the body weight of the host voles.The coefficients(r)of linear correlation between the infestation(parasite species and individuals)and the body weight of the hosts had no statistical significance in gamasid mites,sucking lice and fleas.
