目的通过常规监测和专项调查,掌握宁陕县鼠类种群结构和数量动态变化,为防治鼠传疾病提供科学依据。方法野外夜行鼠监测采用5 m夹(笼)线法,家鼠密度监测采用夹夜法;对2010-2013年鼠情监测资料进行描述性分析。结果 4年共捕获啮齿动物650只,经鉴定属4科9属15种,年平均野鼠密度为4.06%,家鼠为4.68%。结论宁陕县优势鼠种为黄胸鼠和褐家鼠,鼠密度年际波动与灭鼠活动密切相关。根据鼠密度监测结果,在肾综合征出血热(HFRS)流行季节,适时开展群众性灭鼠,可以有效降低鼠密度。
Objective To monitor the dynamic changes of rodent population structure and population in Ningshan County through routine monitoring and special investigation so as to provide a scientific basis for the prevention and treatment of rodent disease. Methods 5 m clip (cage) line method was used for the detection of wild nocturnal animals, and the Jiayin method was used for density monitoring of rodents. The descriptive analysis of rodents monitoring data from 2010 to 2013 was conducted. Results A total of 650 rodents were captured in 4 years. There were 15 species belonging to 9 families, 4 families and 9 genera in 4 years. The average annual density of rodents was 4.06% and that of domestic mice was 4.68%. Conclusion The predominant rat species in Ning Shan County is Rattus flavipectus and Rattus norvegicus, and the interannual fluctuation of mouse density is closely related to rodent infestation. According to the result of rat density monitoring, mass rodent control can be effectively conducted in the epidemic season of hemorrhagic fever with renal syndrome (HFRS), which can effectively reduce the rat density.
