Technical Abstract: The nocturnal mosquito, Culex quinquefasciatus,as a vector of West Nile virus is the target of many surveillance and control efforts. Surveillance of this species primarily consists of light traps baited with a variety of chemical lures. While much research has focused on optimization of the olfactory lures, little has been done on the role of vision in attraction of this insect. Using electroretinograms, the spectral sensitivities of male and female Culex were determined. Regions of maximal sensitivity were matched by theoretical pigment absorption curves to determine the composition of photopigments present. These data in conjunction with behavioral studies can provide the basis for more effective surveillance traps.
