West Nile virus (family Flaviviridae, genus Flavivirus, WNV) is a mosquito-borne zoonosis infecting humans, birds, horses, and other mammals, such as dogs, bats, rodents, rabbits, cats, raccoons, and skunks. It first occurred in the United States in 1999, in New York City, but it has since rapidly spread across the country. A flavivirus native to A...
Study Sites.
Trapping studies were conducted at two sites, a swine research facility at the University of Florida, Alachua Co. (29° 37′ N, 29° 37′ W) and a commercial dairy farm in Marion Co. (28° 58′ N, 82° 24′ W). At each site, there was a highly eutrophic lagoon, containing livestock effluent, surrounded by a variety of vegetation types. The vegetation surrounding the lagoon at the swine research facility consisted primarily of oak (Quercus spp.); elderberry, Sambucus canadensis L.; wax myrtle, Myrica...
Trap Types.
Four trap types were used in these studies. Two trap types have been used for years (Centers for Disease Control [CDC]-type miniature light trap and CDC gravid traps) and two that use relatively new counterflow technology (Kline 1999, Kline 2002). The CDC type trap used was the New Standard Miniature Light Trap-model 1012 (John Hock Company, Gainesville, FL), which uses an incandescent light (CM47 bulb) source. In addition to light the traps were baited with CO2 (500 ml/min). In these studies...
Experimental Design.
The experimental design used at both the swine unit and dairy farm was a 4 by 4 Latin square (Steel and Torrie 1980). Within each Latin square, there were four rows (days) each comprising one of four consecutive 24-h periods, and within each row, four blocks (positions), each comprising a separate physical location for each of four types of mosquito traps (treatments). The four traps, one of each type, were placed around the perimeter of each lagoon so that no trap was located closer than 33...
Cx. nigripalpus, Cx. quinquefasciatus, Culex erraticus Dyar & Knabb, and Cx. salinariuswere captured at both the Hidden Hammock dairy and the University of Florida Swine Research Unit (swine unit) study sites.
These data indicate that the concept that "one size fits all" does not apply to trap efficacy and Culexmosquito species. Indeed, trap efficacy differed according to trap type, mosquito species, gonotrophic condition of the female mosquitoes, and the geographic location that the species was collected. In this study, the GT was a good trap for collec...

Oct 23, 2021 · Conclusions. Our updated contemporary Culex distribution maps may be used to assess mosquito-borne disease risk. It is critical to understand the current geographical distributions of these important disease vectors and the key environmental predictors structuring their distributions not only to assess current risk, but also to understand how they will respond to climate change.
• A female Culex mosquito lays eggs one at a time. Eggs stick together to form a raft of 100 to 300 eggs. The raft floats on the water. Larva • Larvae hatch from mosquito eggs and live in water. • Larvae can be seen in the water. They are very active and are often called “wigglers”. • They feed on materials found in the water.
