河北省不同地区住宅区鼠密度监测结果分析

Surveillance analysis of rodent density in different residential areas of Hebei province

目的监测河北省不同地区住宅区鼠类消长规律、季节分布和鼠种构成。方法夹夜法和粉迹法。结果共捕获各种鼠类2科4属6种,以褐家鼠为优势种,占60.99%,其次为小家鼠、黑线姬鼠、大仓鼠和黑线仓鼠,分别占25.30%、9.38%、2.89%和0.48%;但不同地区鼠类优势种略有不同。鼠密度高峰期出现在4月和10月。廊坊地区采用不同监测方法的监测结果显示,夹夜法监测鼠平均密度为0.87%;粉迹法监测鼠平均密度为3.36%。石家庄和唐山地区住宅区采用夹夜法监测鼠密度年平均值分别为0.83%和0.67%,两个地区农村的鼠密度均高于城镇。结论褐家鼠是河北省重点防制鼠种。

Objective To monitor the population density and seasonal fluctuation of rodents in different residential areas of Hebei province. Methods The night trapping method and powder trace method were used in this study. Results There were 6 species caught, belonging to 2 families 4 genera. Rattus norvegicus was the dominant species （60.99%）. Mus musculus, Apodemus agrarius, Tscherskia triton and Cricetulus barabensis followed with it, accounting for 25.30%, 9.38%, 2.89% and 0.48% respectively. The dominant species were different in different districts. The results showed that the peaks of population density were in April and October. Different surveillance methods were used in Langfang, and the average population density of rodents was 0.87% by night trapping method, but it was only 3.36% by powder trace method. It was 0.83% and 0.67% in Tangshan and Shijiazhuang, respectively. The population density in the country was higher than that in the town. Conclusion R.norvegicus is the main control target in Hebei province.
