Effect of temperature on Culex tarsalis (Diptera: Culicidae) from the Coachella and San Joaquin Valleys of California
Journal of Medical Entomology 32 (5), 636-645
Abstract: The F₁ progeny of Culex tarsalis Coquillett females from the Coachella (CV) and San Joaquin (SJV) valleys collected during April 1991, and April, July, and October 1993 were reared and maintained as adults at 5 constant temperatures ranging from 14 to 38°C. CV F₁ progeny exhibited smaller body size, enhanced survival during spring, and higher autogeny rates than SJV F₁ progeny; however, upper and lower thermal tolerance limits, immature developmental rates and survivorship, and adult life table parameters were relatively similar, for both strains. Mosquitoes from both sites exhibited midsummer changes in immature developmental rates and survivorship, adult wing length, life expectancy at emergence, and generation time. These data indicated that temperature may select for both spatial and temporal changes in mosquito biology.
