2012-2016年锦州市鼠密度监测分析

Rodent density analysis in Jinzhou City from 2012 to 2016

目的通过对鼠监测结果的统计分析,为科学指导鼠类防控工作提供理论依据。方法采用夹夜法于每月中旬对居民区、食品餐饮业、农村村内和村外4个监测点进行监测。结果 2012-2016年锦州市共布有效夹35 217夹次,捕鼠752只,5年鼠密度分别为2.25%、2.24%、2.19%、1.88%和2.13%,农村鼠密度高于城市鼠密度。主要鼠种有褐家鼠、黑线仓鼠、小家鼠,构成比分别为67.64%、17.64%、14.46%,褐家鼠为优势种。结论通过连续5年的监测基本掌握了锦州市鼠类活动规律,为鼠类的科学防治提供了依据。

Objective To provide a theoretical basis for the scientific guidance of rodent prevention and control work through statistical analysis of the monitoring results of rats. Methods Night trapping method was carried out to monitor the rodent on mid month in residential areas, catering services, the villages and the rural villages outside. Results Totally 35 217 traps were placed in Jinzhou from 2012 to 2016,and 752 rodents were captured.The yearly rodent densities were 2. 25% ,2. 24% ,2. 19%, 1.88% and 2. 13% from 2012 to 2016.The rodent density in villages was higher than in city.The main rodents were Rattus norvegicus, Cricetulus barabensis and Mus musculus, respectively accounting for 67.64%, 17.64% and 14.46%. Rattus norvegicus was the dominant species. Conclusion The population structure and densities of rodents in Jinzhou were better understood. It provided scientific guidance for rondent control.
