Abstract
Mosquito faunal studies were carried out 2004-2005 in Maryland's Eastern Shore wetlands managed by the US Department of Agriculture. The wetlands included flooded fields, inundated woodlands, and tidal salt marshes. Sampling methods included larval collections, adult landing counts, and CDC light and oviposition traps. A total of 1,186 larvae and 1,363 adults identified represented 14 species. Temporary pools were found to have the highest potential for rapid mosquito colonization with Psorophora columbiae the predominant species. Aedes vexans, Culex territans/pipiens, Ps. ciliata/howardii, and Anopheles crucians were collected primarily from pond and flooded woodlands. Ochlerotatus sollicitans larvae were sampled from tidal pools. The predominant daytime landing count species was Oc. sollicitans with Ps. ciliata, Ae. vexans, and Cx. territans also identified. Light traps collected An. crucians, the principal crepuscular species from flooded wooded areas. Aedes atlanticus, An. quadrimaculatus, Coquillettidia perturbans, Cx. restuans, Oc. sollicitans, Ps. ciliata, Ps. columbiae, and Uranotaenia sapphirina were also identified. Oviposition traps collected small numbers of An. crucians at the tidal marsh, 1 Ae. albopictus, and 1 each of Cx. territans/pipiens from the flooded woodlands. As a result of this study, it was recommended that abatement strategies be implemented during and after wetland construction to minimize the creation of temporary pool breeding sites.
