Objective To gather the basic information of small mammals and their ectoparasites in Wucai mountain scenic area of Beijing, including species composition, predominant species and parasitism, and to provide basic data for the prevention and control of related natural epidemic diseases. Methods Small mammals were captured alive with baited mouse traps at different representative habitats in Wucai mountain scenic area from January to December 2017. All the ectoparasites of the hosts were thoroughly collected. Small mammals and ectoparasites were identified and classified separately. Excel 2010 and SPSS 19.0 softwares were used to collate and analyze data. The composition ratio (C), prevalence (P), and average ectoparasite abundance (A) were determined to reflect the prevalence and density of ectoparasites. Results In 2017, a total of 73 small animals were captured in Wucai mountain scenic area of Beijing. The catch rate was 3.41%. The captured small mammals were identified as belonging to 2 species, 3 families, 6 genera and 7 species. Apodemus agrarius was the predominant species in studied areas. Of the 73 small animals, 42 (57.53%) were infested with 6 species of ectoparasites, including 2 species of chigger mites, 1 species of gamasid mites, and 3 species of fleas. The total infestation index was 10.70 (781/73) and the infestation rate and total infestation index were higher in autumn. Chigger mites were the predominant parasite populations on the surface of small mammals. Conclusion The structure of small mammals and their ectoparasites communities are complicated in Wucai mountain scenic area of Beijing. It is important for the prevention and control of related natural epidemic diseases in this area to focus on the ecological investigation and analysis.
