摘　　要：目的掌握隆林县蚤类的种群分布特征,为制定鼠疫防治对策提供依据。方法采用笼捕法捕获鼠,采集鼠体蚤,计算鼠体染蚤率和蚤指数。粘蚤纸法捕获室内游离蚤,计算地面游离蚤指数。结果共捕获蚤5 783只,隶属3科6属6种,印鼠客蚤占种群的79.25%,为优势蚤种。鼠体平均染蚤率为27.99%,平均蚤指数为0.980,印鼠客蚤指数为0.780,地面游离蚤指数为0.045。月均染蚤率与印鼠客蚤指数季节消长趋势基本一致,呈单峰型,而蚤指数的季节消长呈2个峰期,分别是3月和7月。结论根据隆林县鼠疫寄生蚤种群分布和季节消长规律,印鼠客蚤是该县鼠疫控制中的主要防治对象,2～10月是鼠疫监测的重点期。Objective To master the distribution of fleas population and provide with the evidences for the policy making in Longlin County of Guangxi Province.Methods Fleas were collected from rodents captured by cage traps,and free flea on room floor were also investigated with sticky paper method.Results Totally 5 783 fleas were captured,Six species belonging to 6 genera,three families of siphonaptera were found in this area.Xenopsylla Cheopis was dominant species in the flea community.The average rodents infected with flea,index of fleas,index of Xenopsylla Cheopis and free flea on room floor were 27.99%,0.980,0.780 and 0.045.The seasonal variation tendency of average monthly rodents infected with flea and X.Cheopis index was similar,there were only one peak,and two peaks in the seasonal variation curve of index of fleas,it＇s March and July.Conclusion The results show that Xenopsylla Cheopis is the targeted subjects in the control of plague,and the important surveillance period is form February to October according to the population distribution of parastitical fleas and its seasonal variation in Longlin County.
