Objective To master the species and seasonal fluctuation of mosquitoes, and provide scientific basis for mosquitoes control in Beijing ports. Methods CO2- baited trap and net trap methods were used for the surveillance of adult mosquitoes, and the scoop dipping method for the surveillance of larvae. Results A total of 14 270 mosquitoes were collected, belonging to 4 genera and 6 species. They were Anopheles sinensis, Culex pipiens pallens, Cx.tritaeniorhynchus, Aedes albopictus, Ae.vexans and Armigeres subalbatus. As many as 114 mosquito larvae were collected, which were Cx.pipiens pallerts and Cx.modestus. The dominant specie was Cx.pipiens pallens and its active peak was September. Conclusion The integrated management should be taken for a long time to control mosquitoes in Beijing ports.
