达乌尔黄鼠(简称黄鼠)是我国松辽平原达乌尔黄鼠鼠疫自然疫源地的主要宿主动物,其体外寄生蚤,是该疫源地的主要传播媒介,蚤指数又是媒介效能的主要参数。因此,黄鼠体蚤指数为鼠疫监测的内容之一。关于黄鼠体外寄生蚤指数监测的样本抽取比例报道所见甚少。为在疫源地监测中,寻求能代表黄鼠体外寄型生蚤指数的鼠体数最小样本比俐,进行了调查研究。
Daurian ground squirrel (Chrysolophus pictus) is the main host animal of the natural foci of Daurian ground squirrel in the Songliao Plain, and its parasitic fleas are the main media of transmission in this area. The flea index is also a medium The main parameters of effectiveness. Therefore, the yellow rat body flea index is one of the contents of plague monitoring. There are few reports on the proportion of samples taken for the monitoring of the parasites’ flea index in chinchillas. In order to find out the minimum number of mice that can represent the index of the sentinel flea in the yellow rat in the surveillance of the foci, Bili was investigated.
