Arizona 07/27/10 ktar.com: by Holiday Moore – Phoenix – The number of mosquitoes in the Valley that carry the deadly West Nile virus has doubled since this time last year, according to the Maricopa County Department of Environmental Services. And, they’re multiplying fast, said the department’s John Townsend. The Culex mosquito is the one that carries West Nile virus. Mosquitoes testing positive for West Nile have been found all over the Valley, Townsend said. “It runs the gamut from a tract home neighborhood to farming and flood irrigation to horse properties.” Culex mosquitoes are not the ones you see at dawn and dusk, he said. “They’re active at nighttime, after the sun goes down, at 9, 10, 11 o’clock at night.” The Culex breeds in murky swimming pools, dog dishes and kiddie pools. If water stands for more than five days, chances are the Culex is breeding there, said Townsend. “Within about five and a-half to seven days, they can go from an egg to an adult and then they’re out trying to find their blood milk,” he said. Maricopa County vector control has been spraying for the Cutex mosquito across the Valley, from Gilbert to Peoria. The county has had 10 cases of West Nile virus this year, most of them in the East Valley, including a woman who died in early July.
