Thirteen species of mosquito larvae were identified in 336 visits (167 and 169 visits to peridomestic and forested sites, respectively) to 112 tire dump sites in Fayette, Nicholas and Raleigh counties of West Virginia from May through September, 2002. Ochlerotatus triseriatus was the most frequently encountered species from May through August, with Aedes albopictus and Oc. japonicus being more frequently encountered in September. Ochlerotatus atropalpus was significantly more likely to be collected at forested sites, but none of the other species exhibited a significant predisposition for either peridomestic or forested settings. The potential for competitive displacement of Oc.triseriatus by the invasive Asian species is discussed.
Species 1: Diptera Culicidae Ochlerotatus triseriatus
Species 2: Diptera Culicidae Ochlerotatus japonicus
Species 3: Diptera Culicidae Aedes albopictus (Asian tiger mosquito)
Keywords: larval habitats, competitive exclusion
