2007-2011年浙江省义乌市历史鼠疫疫源地宿主和媒介种群调查

Survey of host and vector species of plague in previous natural focus in Yiwu,2007-2011

  • 摘要: 目的 通过对浙江省义乌市地区历史鼠疫疫源地宿主、媒介种群构成和密度调查,为制定鼠疫预防控制措施提供参考。 方法 采用夜笼法捕鼠,对鼠及蚤类进行鉴定和分析。 结果 2007-2011年共捕获鼠形动物3725只,啮齿目2科7属11种,食虫目1科1属1种。家栖鼠类主要为褐家鼠、黄胸鼠;野鼠类主要为黑腹绒鼠、黑线姬鼠。鼠密度为0.98%,其中室内为1.01%,室外为0.93%。染蚤鼠种主要为白腹巨鼠、小家鼠、褐家鼠和黄胸鼠。鼠体蚤以缓慢细蚤为优势种,占97.35%。鼠体染蚤率为0.82%,总蚤指数为0.019。 结论 褐家鼠和黑腹绒鼠是义乌市历史鼠疫疫源地室内、外的优势鼠种。宿主动物和媒介种群密度低,尚未发现印鼠客蚤,应继续开展鼠疫监测,及时发现异常动态。

     

    Abstract: Objective To understand the species of host and vector of plague and their density in previous natural focus in Yiwu and provide evidence for the development of plague prevention and control measures. Methods The rats were captured with cages at night, and the captured rats and fleas were identified and analyzed. Results The total number of rodent like animals captured was 3725 from 2007-2011, the rodentia belonged to 11 species in 7 genera in 2 families and the insectivora belonged to 1 species in 1 genus in 1 family. The predominant rats in house were Rattus norvegicus and Rattus flavipectus and the predominant rats in field were Eothenomys melanogaster and Apodemus agrarius. The total rat density was 0.98% (1.01% for rats in house and 0.93% for rats in field). The major rats infected by flea were Rattus edwardsi, Mus musculus, Rattus norvegicus and Rattus flavipectus. Leptopsylla segnis was the predominant flea found in rats (97.35%), the flea-carrying rate in rats was 0.82%, and the total index of flea was 0.019. Conclusion Rattus norvegicus and Eothenomys melanogaster are predominant rat species in previous natural focus of plague in Yiwu. The densities of the disease hosts and vectors were low, and no Asiatic rat flea was found, but it is still necessary to continue the surveillance of plague in this area.
