摘    要:[目的]调查云南省印鼠客蚤的地域分布,并研究其是否与鼠疫分布一致。[方法]在云南省的22个县(市)进行现场抽样调查,采集小兽体表的印鼠客蚤并现场鉴定所获宿主,分析印鼠客蚤的地域分布、蚤指数、染蚤率。[结果]所捕获的60种小兽中,黄胸鼠的总染蚤率最高(13.04%),体表所采集的印鼠客蚤(1268)最多;褐家鼠有最高的蚤指数(0.83)。4个动物地理小区中,滇东高原小区的蚤指数(0.9)和染蚤率(21.73%)最高。[结论]印鼠客蚤主要分布在滇东高原小区,蚤指数、染蚤率和鼠疫发病率三者在云南省分布趋势相同。

Abstract:[Objective]The aim was to study the geographical distribution of Xenopsylla Cheopis and the relationships of the incidence of plague,flea infection rate and flea index.[Method]The field investigation was carried out in 22 counties (towns) in Yunnan Province. All the captured small mammal hosts were identified mainly in the investigation sites and the fleas collected on the hosts. Data of Xenopsylla Cheopis was gathered to statistically analyze its geographical distribution,Rf value and If value. [Result]From 1997 to 2008,Xenopsylla Cheopis were collected from small mammals in four zoogeographical microregions in Yunnan. 60 small mammal species were collected. Rattus flavipectu had the highest X.cheopis load(with 1 268 X.cheopis from 3 849 R.flavipectu) and the highest overall flea infection rate(13.04%),while R. norvegicus had the highest overall flea index(0.83). In four zoogeographical microregions,eastern plateau microregion of Yunnan had the highest flea index(0.9) and the highest flea infection rate(21.73%). [Conclusion]Xenopsylla Cheopis was mainly distributed in the eastern plateau microregion of Yunnan,the If value,Rf value and the incidence of plague had the same distribution tendency.
