Seasonality of Mosquitoes in North Dakota, 2003-2006, with Four New State Records.

ABSTRACT

Thirty-seven species and subspecies of mosquitoes were identified from 3,580,610 specimens collected in eastern (Cass, Nelson, and Richland counties) and western (Williams County) North Dakota in 2003-2006. Four species were new state records (Aedes schizopinax, Psorophora ciliata, Ps. ferox, and Ps. horrida). Aedes vexans was dominant (82.9%). Other relatively abundant species were Ae. trivittatus (7.7%), Ae. melanimon (2.7%), Culex tarsalis (2.6%), Ae. dorsalis (1.6%), Ae. sticticus (1.0), and Culiseta inornata (0.9%). The seasonality of the species is presented.
