How do daytime temperatures affect mosquito populations?

Gardens & Landscapes February 12, 2011 Print Friendly and PDF
The mosquitoes that transmit West Nile virus, Culex spp., overwinter as adults. They can become active in spring when temperatures warm up enough for flight and warm nights allow them to fly at night. Once they start breeding, they can continuously produce eggs throughout late spring and summer with overlapping generations being produced. The warmer the spring, the more quickly mosquito generations are produced. Flights continue until evening temperatures begin to cool and the mosquitoes go into winter dormancy.
