Abstract：Objective To investigate the species composition and seasonality of blood-sucking midges in Bohai New Area of Cangzhou, Hebei province, China. Methods Blood-sucking midges were collected in Bohai New Area using light traps and insect nets from April to October, 2018, with slaughterhouses, quarantine farms, henhouses, hog houses, stables and residential areas as the selected observation points. Results A total of 5 107 blood-sucking midges, belonging to 1 genus and 7 species, were collected in Bohai New Area, of which Culicoides humeralis was recorded for the first time in Hebei province, and the dominant species was C. homotomus (72.22%). The species composition of blood-sucking midges varied between different places and months. The active season of blood-sucking midges was from the second half of April to the first half of October, and there were two peaks:the first half of June (53.72 inds/lamp) and the second half of August (71.88 inds/lamp). There were two peaks of activity, the first half of June (37.24 inds/lamp) and the second half of August (68.41 inds/lamp), for C. homotomus. There were two peaks of activity, the second half of May (16.08 inds/lamp) and the first half of August (23.22 inds/lamp), for C. morisitai. The total index of blood-sucking midges captured by the light traps from April to October was 21.46 inds/lamp, and the index of blood-sucking midges captured by the light traps varied across different months. Conclusion This investigation provides a reference for studies of the species composition and seasonal variation of blood-sucking midges and midge-borne diseases in the Bohai New Area of Cangzhou, Hebei province, China.
