恙螨是啮齿动物常见的体表寄生虫，也是恙虫病的唯一传播媒介。东南亚褐家鼠（Rattus brunneusculus）是包括恙虫病在内的一些人畜共患疾病的重要宿主和传染源。2016年4月至2017年3月，对云南省南部重要恙虫病疫区景哈村进行了为期12个月的连续调查。在调查的基础上，研究了恙螨对褐螺旋体恙螨的侵害及季节消长。在捕获的2053只布伦neususr中，共捕获恙虫99221只，鉴定为102种，物种多样性非常高。不同月份鼠体上恙螨群落的丰富度(S)、多样性指数（H’）、均匀度(E)和优势度指数(D)各不相同。102种恙螨中，主要5种占84.81%（84,147/99,221）。5种主要恙虫为：微小恙虫（32.65%）、印度细恙虫（24.68%）、斑点细恙虫（19.02%）、turmalis小恙虫（4.63%）和scutellare小恙虫（3.83%）。在5种恙螨中，德氏恙螨和scutellare恙螨是中国最重要的恙虫病媒介。五种恙螨表现出不同的季节消长规律。季节消长以夏秋型为主，7月为高峰；冬春型为主，1 - 2月为高峰；气温和降雨是影响恙螨季节消长的两个关键因素。恙螨是啮齿动物的常见外寄生虫和恙虫病的媒介。褐毛鼠是人畜共患病的宿主和传染源。brunneusr孳生恙螨102种，物种多样性较高。恙虫病的两大主要传播媒介是鹅绒恙虫病和鹅绒恙虫病。气温和降雨影响恙螨的季节消长。
Chigger mites are the common ectoparasites of rodents and the exclusive vector of scrub typhus. The Southeast Asian house rat (Rattus brunneusculus) is an important reservoir host and infectious source of some zoonoses including scrub typhus. From April 2016 to March 2017, a 12-month consecutive investigation was made at Jingha village in southern Yunnan of China, which is an important focus of scrub typhus. The infestation and seasonal fluctuation of chigger mites on R. brunneusculus were studied based on the investigation. From 2,053 captured R. brunneusculus, a total of 99,221 chiggers were collected and identified as comprising 102 species with very high species diversity. The richness (S), diversity index (H′), evenness (E) and dominance index (D) of the chigger community on the rat varied in different months. Of the 102 chigger species, five main species accounted for 84.81% of the total chiggers (84,147/99,221). The five main chiggers were Walchia (W.) micropelta (32.65%), Ascoschoengastia indica (24.68%), Leptotrombidium (L.) deliense (19.02%), W. (W.) turmalis (4.63%) and L. (L.) scutellare (3.83%). Of the five chigger species, L. (L.) deliense and L. (L.) scutellare are the most important vectors of scrub typhus in China. The five chigger species showed different patterns of seasonal fluctuation. The seasonal fluctuation of L. (L.) deliense belonged to summer-autumn type with the highest peak in July, but L.(L.) scutellare mainly appeared in winter and spring with the peak from January to February. The temperature and rainfall were two key factors which influenced the seasonal fluctuation of chigger mites. Chiggers are the common ectoparasites of rodents and vector of scrub typhus. Rattus brunneusculus is the reservoir host and infectious source of zoonoses. R. brunneusculus harbored 102 chigger species with high species diversity. L. deliense and L. scutellare were two major vectors of scrub typhus. Temperature and rainfall influenced the seasonal fluctuation of chiggers.
