Seasonal incidence and geographical variation of Nebraska mosquitoes, 1994-95

A mosquito survey was conducted in Nebraska during 1994-95. Mosquitoes were collected by CO2-baited CDC light traps at 11 localities throughout Nebraska. Total mosquitoes collected was 685,581 per trap (mean = 790) and 1,163,741 per trap (mean = 1,372) during 1994 and 1995, respectively. Twenty-seven mosquito species representing 8 genera were collected. The most abundant mosquitoes collected statewide were Aedes vexans at 74% of the 2-year total, Culex tarsalis at 11%; Aedes trivittatus, 5%; Aedes melanimon, 1.5%; and Aedes triseriatus, 1%. The floodwater mosquitoes were more prevalent in eastern Nebraska while standing-water mosquitoes, especially Culex tarsalis, were more prevalent in the west.
