Description:Caption:
This 1976 photograph depicted a Colorado roadside drainage ditch, which was draining irrigation tailwater, and was a known habitat and breeding site for Culex tarsalis mosquitoes. The epidemiologic importance of C. tarsalis lies in its ability to spread Western equine encephalitis (WEE), St. Louis encephalitis (SLE), and California encephalitis, and was at one point, the main vector of West Nile virus (WNV) in the western United States.
