Abstract: Objective Through the investigation and analysis to understand the impact of capital's second airport construction in Langfang on adult mosquito species, quantity, distribution and seasonality, provide reference for prevention of mosquito-borne diseases. Methods In the construction area of the suburban airport of Langfang, mosquito light trap with CO2 was used during 2015-2016. Excel and DPS v15.6 software were used to analyze mosquito density and its seasonal trend. Results In total, 4 925 mosquitoes were captured in the second capital airport construction of Langfang area during 2015-2016. The predominant species was Culex pipiens pallens accounting for 53.63%, followed by Cx. tritaeniorhynchus, Aedes albopictus and Armigeres subalbatus.
