Abstract
Field collections of mosquito larvae were conducted from 12 different larval habitats found at 34 collection sites in Ehime prefecture, western Japan during 2009-2010. A total of 24 mosquito species in 8 genera were collected, including the following 6 newly recorded species from Ehime Prefecture; Culex infantulus, Aedes oreophilus, Ae. koreicoides, Ae. kobayashii, Topomyia yanbarensis and Orthopodomyia anopheloides. Three dominant species, Ae. japonicus, Tripteroides bambusa and Cx. sasai, occupied a wide variety of larval habitats and occurred in the entire period of mosquito breeding season from April to November. Four of the newly recorded species, Aedes oreophilus, Ae. koreicoides, Ae. kobayashii, To. yanbarensis were found from restricted types of larval habitats, such as stone pot, bamboo stump and bamboo internode, and larvae occurred in a limited period of breeding season from April to July, suggested a low chance of encounter during larval collections.
