摘要
报道吉林省鼠疫地区的二齿新蚤和印鼠客蚤,在感染分离自达乌尔黄鼠的鼠疫毒菌后,其鼠疫媒介效能的实验室测定结果。在18—20℃,相对湿度80—90%条件下,二齿新蚤的鼠疫媒介效能为0.11,媒介指数为0.01;印鼠客蚤的鼠疫媒介效能为0.24,媒介指数为0.03。结合多年的野外调查资料,认为在把达乌尔黄鼠鼠间鼠疫播散到其它啮齿类包括家栖鼠类之间的过程中,二齿新蚤起重要作用。
This study was carried out to determine the experimental plague—vector efficiency of neopsylla bidentatifor-mis compared with xenopsylla cheopis after both species had been infected with a virullent plaviprain(55012)iso-lared from a vector,which caught from the plague arreas in jilin provice.The experiments at 18—20,80—90% showed that the vector efficiencies and vector indices were,respectively,as follows:0.11,0.01 in N.bidentatiformis and 0.24,0.03 in X.cheopis.
