Larval mosquitoes in abandoned tire pile sites from West Virginia.

Larvae of 13 mosquito species were collected from abandoned tire piles at peridomestic and nonperidomestic sites in 3 south-central West Virginia counties from May through September 2002. Ochlerotatus triseriatus was the most frequently collected species from May through August, whereas Aedes albopictus and Ochlerotatus japonicus were more prevalent in September. Prevalence of Oc. triseriatus and Culex restuans declined throughout the study period. Conversely, prevalences of Ae. albopictus, Oc. japonicus, Culex territans, and Toxorhynchites rutilus increased during the same period. Ochlerotatus atropalpus was significantly more likely to be encountered at nonperidomestic sites. None of the other species exhibited a significant predisposition for either peridomestic or nonperidomestic sites.
