Objective To analyze ecological characteristics of rodents of rodent population density, seasonal fluctuation, interannual variation and habitat differences, and their correlation with meteorological factors by rodent monitoring data of 2013-2019 in Weifang, Shandong province, China, and to provide a scientific basis for effective prevention and control of rodent-borne diseases in Weifang. Methods The rodent density was monitored monthly using the night trapping method in selected urban residential areas, special industries, and rural villages across Weifang. SPSS 26.0 and R 4.2.1 were used for statistical analysis. Results A total of 301 rodents were captured in Weifang from 2013 to 2019. Rattus norvegicus was the dominant species, accounting for 61.13% of the total catches, and Mus musculus accounted for 35.22%, with an overall rodent density of 0.64%. Among the three habitats, rodents were more frequently captured in rural villages, accounting for 54.49% of the total catches. The rodent density peaked during January to March in each year, and the densities of R. norvegicus and M. musculus peaked in February. The wavelet analysis showed that monthly rodent density had wavelet correlations with monthly average temperature, monthly average precipitation, and monthly average relative humidity, with a negative correlation with monthly average relative humidity. Conclusion Rodent control measures should be based on the inhabiting habits and activity patterns of different rodent species, to effectively reduce rodent density and control rodent-borne diseases.
