目的 了解云南省大绒鼠体表恙螨的寄生状况,包括恙螨的种类构成、优势螨种及其在不同宿主个体间的空间分布情况、主要螨种的种间关系以及雌雄宿主(大绒鼠)体表恙螨感染差异.方法 汇总2001-2012年在云南省27县(市)的现场调查资料,常规统计计算大绒鼠体表恙螨的种类数和各种恙螨的构成比、感染率、平均多度和感染度等指标,并以此来反映大绒鼠体表恙螨的感染状况;用扩散系数、Ⅰ指数、Cassie指数、聚块指数测定主要恙螨在大绒鼠不同个体间的空间分布情况;用协调系数分析主要恙螨之间的种间协调关系,分析比较雌雄大绒鼠体表恙螨的感染差异. 结果 从云南省27县市共捕获大绒鼠1 961只.从1 961只大绒鼠体表共采集到44 235只恙螨,总感染率和感染度均较高,分别为58.8％和38.3只螨/鼠.所采集到的44 235只恙螨被分类鉴定为3科12属130种.在130种恙螨中,小板纤恙螨的构成比最高,为22.6％(9 986/44235),是云南省大绒鼠体表最主要的优势种;其次是中华纤恙螨,构成比为13.1％(5 776/44 235).空间分布分析显示,小板纤恙螨与中华纤恙螨等主要恙螨在大绒鼠不同个体间呈聚集分布格局.种间协调分析显示,小板纤恙螨与中华纤恙螨存在正协调关系(V=0.557 4,P＜0.01).雌性大绒鼠与雄性大绒鼠恙螨的寄生状况有一定的差异,雄性大绒鼠的总平均多度和总感染度分别为25.1和41.0,均高于雌性大绒鼠的19.6 (t=2.479,P＜0.05)和34.1 (t=1.985,P＜0.05). 结论 云南省大绒鼠体表恙螨感染普遍,恙螨种类十分丰富,小板纤恙螨是云南省大绒鼠体表最重要的优势螨种,其次是中华纤恙螨,二者之间存在正协调关系.恙螨在雌雄大绒鼠间的感染情况存在差异,雄性大绒鼠的感染度和平均多度均高于雌性.

Objective To understand the infestation and related biological issues of chigger mites on the body surface of Yunnan red-backed voles(Eothenomys miletus) in Yunnan Province of China,which include the mite species composition,dominant mite species and their spatial distribution patterns among different individuals of the vole hosts,the interspecies association and the difference of infestation between male and female hosts.Methods The original investigation data came from 27 counties of Yunnan Province from 2001 to 2012.The constituent ratio,prevalence,mean abundance and mean intensity were used to evaluate the infestation status of chigger mites on Eothenomys miletus.The dispersion coefficient,I index,Cassie's index and patchiness index were used to measure the spatial patterns of the dominant chigger mite species among different individuals of the vole hosts.The association coefficient was used to analyze the interspecies association between every two dominant mite species.The difference of infestation was compared between male and female hosts.Results A total of 1 961 individuals of Yunnan red-backed voles was captured from 27 counties of Yunnan Province.Of these 1 961 voles,44 235 chigger mites were collected with a high overall infestation rate (58,8％) and a high overall mean abundance (38.3).The collected 44 235 individuals of chigger mites were identified as 130 species and 12 genera in 3 subfamilies.Of the 130 species of chigger mites,Leptotrombidium scutellare had the highest constituent ratio (22.6％,9 986/44 235) and L.sinicum (13.1％,5 776/44 235) came next.These two mite species were the most predominant species of chigger mites on Yunnan red-backed voles.The measurement of spatial patterns showed that the dominant chigger mite species such as L.scutellare and L.sinicum exhibited an aggregated distribution among the different individuals of their vole host,E.miletus.The analysis of interspecies association revealed that a positive association existed between L.scutellare and L.sinicum (V=0.557 4,P＜0.01).The infestation of chigger mites was different between the male and female voles.The overall mean abundance and mean intensity of chigger mites on the male voles(25.1,41.0) were higher than those on the females (19.6,34.1)(t=2.479,1.985,P＜0.05).Conclusions The infestation of chigger mites is common on Yunnan red-backed vole (E.miletus) with abundant mite species.L.scutellare is the most predominant species of chigger mites on the voles,and L.sinicum comes next.A positive association exists between these two mite species.The infestation of chigger mites is different between the male and female voles.The mean abundance and mean intensity of chigger mites on the male voles are higher than those on the females.
