Abstract: Objective To investigate the species and geographical distribution of rodents in the frontier ports of Inner Mongolia, China. Methods The monitoring data of rodents in 12 frontier ports of Inner Mongolia during 2006-2016 were collected and collated. Excel 2007 software was used for statistical analysis of the data on the distribution of rodents in different frontier ports using descriptive epidemiological method. Results During the period of 2006-2016, a total of 5 698 rodents belonging to 32 species, 25 genera, 6 families, and 2 orders were captured in the 12 main ports. The dominant species in the ports were Spermophilus dauricus, Meriones unguiculatus, and Allactaga sibirica. Conclusion The species and geographical distribution of rodents in the frontier ports of Inner Mongolia are understood basically to provide a scientific basis for the control of exotic vectors.
