Abstract: Objective To investigate the community composition of rodents and their densities in different seasons and habitats in Tai’an city, China, and to provide a scientific basis for rodent control measures. Methods The night trapping method was used to monitor the rodent densities at there randomly selected sites, one in special industry, one in natural village, and one in residential community. Results A total of 617 rodents were captured from 2007 to 2011, with a mean density of 2.29%. Of all rodents, the dominant species was Rattus norvegicus (64.18%). The density of rodents was the highest in the natural village, followed by special industry and residential community. The seasonal fluctuations of rodent density in general or in different habitats both followed a double-peak curve, with the first peak in April and May and the second peak in September and October. Conclusion For the rodents in Tai’an, their community composition and seasonal density fluctuation are acquired. It is suggested to take integrated rodent control measures and enhance long-term monitoring, early warning, and prevention of rodents and rodent-borne diseases according to the habits and characteristics of rodents and their seasonal density fluctuation.
