Objective This paper aims to provide insight into activities of Culicoides biting midges so that scientific measures can be taken to prevent epidemic of infectious diseases transmitted by midges. The population compositions and regular activity patterns of Culicoides midges in Zhoushan Jintang district of Zhejiang province were investigated. Methods Fifty-eight monitoring points were set up in the 600 meters of the surrounding areas of the port, the quarantine district, the livestock facilities and along the transport route. Light trap method was adopted and lights were kept on during the night time. Samples were collected in the early morning before sunrise, and species identification was conducted and specimens were prepared for collected biting midges. Results During the period from August 2016 to July 2017, a total of 2 378 samplings were conducted, 2 180 Culicoides midges were collected, of which 405 were males. The collections were identified as 15 species in 4 subgenuses:C. arakawai, C. fukienensis, and C. morisitai accounted for 40.00%, 28.81%, and 23.85% respectively. Population compositions were different in different areas. The midge activity season was approximately from May to October. The activity peak was found in summer, of which August and September were the most active periods. Conclusion The species of Culicoides midges showed biological richness in Jintang district of Zhoushan. The predominant communities were C. arakawai, C. fukienensis, and C. morisitai.
