[Ecology of mosquitoes inhabiting a park in urban Tokyo, Japan: seasonal prevalence of larvae occurred in catch basins]
Medical Entomology and Zoology 63 (2), 95-101
Abstract: Mosquito larvae occurred in catch basins in an urban park in Tokyo, Japan were collected by dipping in 3 consecutive mosquito seasons from May 2003 to December 2005. A total of 90 catch basins in the park were examined monthly, except for winter seasons, and presence of water in each catch basin was recorded. During the whole study period 16,452 larvae of 6 species in 4 genera were collected and the following 4 species were dominant; Culex pipiens pallens, Aedes albopictus, Cx. sasai and Lutzia vorax. The presence/absence of water in catch basin showed a clear seasonal changes and the water retention rate was defined for each catch basin as a percentage of the number of observations with standing water to the total number of observations. Catch basins with >60% water retention rate composed of 24.4% of the total catch basins examined in this study. There was a significant positive correlation between the water retention rate and the mean density of larvae for Cx. pipiens pallens, Cx. sasai and Lt. vorax. Disproportionate production of mosquito larvae was found among catch basins with different water retention rate and the catch basins with >60% water retention rate contributed >80% of the total production of larvae.
