摘要
目的为证实印鼠客蚤(Xenopsylla cheopis)是否在新疆境内在阿拉山口口岸形成种群。方法2004～2006年采用夹日法布夹、布笼、探鼠洞、挖洞、采蚤的方法分别对该地进行了追踪调查。结果在口岸的5个片区30个点的监测中捕获褐家鼠214只,在其体上分别采到印鼠客蚤293只(119♂♂、174♀♀),平均染蚤率20.6%,蚤指数1.4,并在一褐家鼠洞穴中采到6只印鼠客蚤、2只幼虫和3只蛹。结论印鼠客蚤自2001年输入新疆阿拉山口口岸后不仅在该地能生存繁殖,而且已形成种群,对口岸已构成潜在威胁。
Objective To confirm whether Xenopsylla cheopis, which was first captured at Alataw Port in 2001, has formed population or not. Methods Trap - day method was taken to carry out follow - up investigation during the years of 2004 to 2006 by way of putting traps and cages, exploring burrows, caving and catching fleas. Results There were 214 of Rattus norvegicus captured in 30 monitoring points in 5 areas of Alataw Port and 293 of Xenopsylla cheopis parasited on Rattus norvegicus were gotten （ 119 ♂ ♂ , 174 ♀♀ ）. The average infection rate of fleas was 20.6% with the flea index of 1.4. In a cave of Rattus norvegicus, we found 6 Xenopsylla cheopis, 2 larvas and 3 pupas. Conclusions Xenopsylla cheopis can not only live and propagate, but also has formed population since they were transmitted to this area in 2001. It is a potential threat to the port.
