Abstract: Objective To investigate the mosquito population, density and distribution in different habitats at Yunfu port in Guangdong province, and to provide the scientific evidence for controlling mosquito and vector - born infectious diseases. Methods Labour hour method, CDC light traps and mosquito magnet were taken for the survey of adult mosquitoes, scoop dipping method for the survey of larvaes and pupaes which would be identified after captured at the mosquito breeding site. The density of adult mosquitoes was obtained by monitoring mosquitoes with labour hour method in typical habitat. Results A total of 42 367 adult mosquitoes and 3680 larvaes were collected from May to November in 2011, which belong to 3 subfamily, 8 genera and 12 species. The dominant species are Culex tritaeniorhynchus, Cx. pipiens quinquefasciatus and Aedes albopictus successively. There were two peaks of adult mosquitoes density from May to November. The first is May and June, and the second is August. The biting activity of Ae. albopictus arised almost in one day, but the biting rate in the daytime was obviously higher than that at night. There were three biting peaks at one cycle. Conclusion It is the first time to obtain the original information of mosquito population at Yunfu port, which presented the mosquito population under natural conditions and would be useful to the ongoing survey and control of mosquitoes in the future.
