Mosquitoes were collected in Yokohama to clarify the seasonal and local distributions, as a part of the research to investigate the invasion of West Nile virus into Yokohama. CDC light traps combined with dry ice were set up to gather adult mosquitoes in each of 18 parks in 18 wards, three parks, and one public institution in the harbor area during the period from June to October 2005. The total number of mosquitoes was 6,546, and they were divided into 7 genera and 12 species. The dominant species captured was Aedes albopictus (49.6%), followed by Culex pipiens complex (34.4%) and Culex tritaeniorhynchus (7.6%). Culex pipiens complex was observed in each of 22 points throughout the research period, and the number of individuals exceeded those in the harbor area. In contrast, Aedes albopictus was collected mainly in parks of 18 wards. Most of the Culex tritaeniorhynchus were captured at Symbol Tower (park in the Naka Ward Honmoku harbor area).
