Abstract: Objective To get an insight into the distribution and seasonal fluctuation of rodent population and provide the basis for the control of rodents and rodent-borne diseases in Zhejiang province. Methods Rodent density surveillance was conducted once a month by night trapping method, with each surveillanc site covering a residential area, a special industry and a natural rural village. Results It was found that Rattus norvegicus was the predominant species in most areas of Zhejiang province in 2010, followed by Mus musculus and R. tanezumi. The average rodent density in the province was 0.97 per 100 rat traps, with the average density in natural rural villages being 1.23 per 100 rat traps. M. musculus was the predominant species in Hangzhou and Haiyan areas, while R. tanezumi was the predominant species in Quzhou city. The curve of rodent seasonal fluctuation showed a double-peaked pattern. The highest rodent density was seen in Jiangshan city. Conclusion There are several rodent species in Zhejiang province that can transmit diseases, so it is important to strengthen the integrated surveillance to reduce the rodent density for the control of rodent-borne diseases.
