Abstract: The city of Williston, ND, is located at the confluence of the Missouri River and the Little Muddy River and has extensive river floodplains adjacent to it. Mosquito problems have been documented since the early 1800s, and nuisance levels of mosquitoes still exist. The various habitats in the floodplain of the river were examined to determine where primary mosquito breeding sites were located. Data collected indicate that low densities of eggs are deposited in most of the floodplain habitats, with the highest numbers being collected in agricultural fields. In contrast, adult mosquitoes apparently concentrated in higher numbers in trees (willow) and alfalfa fields. The floodplain of the Missouri River system is extensive, and even though mosquito egg density is low, large numbers of adults can be produced from the extensive acreage (24,000 acres) that exists. These floodplain mosquitoes are nuisance mosquitoes and generally are not associated with the transmission of viruses in North Dakota.
