Abstract：Objective To analyze the composition,distribution,and seasonal fluctuations of rodent populations in Aksu City,Xinjiang from 2020 to 2023,so as to provide reliable basis for guiding rodent prevention and risk assessment.Methods The monitoring of rodents was conduct every two months using the night-snap trapping method in urban residential areas,special industries,rural natural villages,and other habitats.SPSS 26.0 software was used to process and statistically analyze the composition of rodent species,density,and seasonal fluctuations from 2020 to 2023.The rates was compared by using the Chi-square test.Results From 2020 to 2023,a total of 91 rodents were captured,with a total rodent density of 0.47％.The dominant rodent species was Rattus norvegicus.There was a statistically significant difference in rodent density between different years(x2=38.749,P＜0.001).Rat density in different habitats:rural natural villages(0.76％)＞special industries(0.58％)＞urban residential areas(0.43％)＞other habitats(0.15％).There was a statistically significant difference in the density of rodent in different habitats(x2=18.264,P＜0.001).The proportions of R.norvegicus,Mus musculus,R.tanezumi,and other rodent species were 84.62％,5.49％,1.1％,and 8.79％,respectively.There was a statistically significant difference in the composition ratio of different rodent species(x2=110.917,P＜0.001).There was no statistically significant difference in rodent species between different years(x2=3 333.333,P＞0.005).Conclusion The density of rodents in rural natural villages in Aksu City is the highest.It is necessary to strengthen the prevention and control of rodents in rural natural villages and enhance the long-term sustainability of urban health management.In 2023,there are signs of rodent species migrating to other habitats.In the seasonal fluctuations of rodent density in different habitats,the highest density of rodents in other habitats occurs in November,indicating signs of rodent migration to other habitats in November.It is recommended to strengthen the monitoring of rodent density in other rodent species and habitats,and take targeted prevention and control measures based on rodent density and seasonal fluctuations in different habitats.
