浙江省病媒生物监测点鼠类监测结果分析

目的 分析浙江省病媒生物监测点鼠类监测结果，了解浙江省鼠类种群密度和季节消长等动态变化规律，为浙江省鼠传播疾病的控制提供基础数据。方法 采用夹夜法进行鼠密度和季节消长监测，每月一次，每个监测点分居民区、特殊行业和农村自然村3个监测类型。结果 2012年浙江省病媒生物监测点以褐家鼠为鼠类的主要优势种，其次为小家鼠和黄胸鼠。全省平均鼠密度为0.82只/100夹。国家级监测点杭州市和省级监测点海盐县以小家鼠为优势种，省级监测点丽水市以黄胸鼠为优势种。鼠类季节消长曲线呈双峰型；江山监测点鼠密度最高，为3.64只/100夹。结论 浙江省病媒生物监测点鼠密度较低，建议国家加强顶层设计，开展鼠类和相关疾病综合监测、预警、控制措施的研究。

Rodents surveillance in Zhejiang province

Objective To understand the density and species of rodents in Zhejiang province and provide evidence for rodent control and the prevention of rodent-borne disease. Methods The night trapping method was used to monitor the species composition and density of rodents. The sutweiUance was conducted in residential area, special industry area and rural natural village every month. Results Rattus norvegicus was the dominant species in most areas of Zhejiang in 2012. followed by Mus musculus and Rattus tanezumi. The average density of rodents was 0. 82 per 100 rattrap. Mus musculus was the dominant species in Hangzhou and Haiyan. Rattus tanezumi was the dominant species in Lishui. Annual density dynamic curve of rodents had peaks. The highest rodent density, 3.64 per 100 rattrap, was recorded in Jiangshan. Conclusion Several species of rodents which can transmit disease were found in Zhejian. It is important to strengthen the top-design, the integrated surveillance and the control of rodent-borne diseases.
