Spatial and temporal distribution of resting female mosquitoes (Diptera: Culicidae) in the coastal plain of North Carolina.

The spatial and temporal distribution of 28 species of female mosquitoes resting in natural (swamp, woods, and swamp-woods ecotone) and human-made (beneath bridges) habitats in blackwater stream-associated ecosystems in Duplin County, N.C., was determined by sampling with a D-Vac vacuum aspirator during 1984 and 1985. Two types of resting distributions were evident. In type one, species including Aedes atlanticus Dyar & Knab, Ae. canadensis (Theobald), Ae. triseriatus (Say), and Psorophora ferox (von Humboldt) rested predominantly on vegetation and were not collected beneath bridges. In type two, species including Anopheles punctipennis (Say), Culex erraticus (Dyar & Knab), Cx. peccator Dyar & Knab, Cx. pipiens L. and Cx. quinquefasciatus Say and their hybrids, Cx. restuans Theobald, Cx. territans Walker, and Uranotaenia sapphirina (Osten Sacken) rested on vegetation, in natural shelters in swamp habitats, and beneath bridges. Differences in the proportion of gravid mosquitoes among habitats were evident for Ae. canadensis, An. punctipennis, Cx. pipiens and Cx. quinquefasciatus and their hybrids, Cx. restuans, Cx. territans, Ps. ferox, and Ur. sapphirina, indicating that gonotrophic condition may influence resting site selection.
