Thermal response in pre-imaginal biology of Ochlerotatus albifasciatus from two different climatic regions
The biological processes on mosquito could be variable in response to local climatic characteristics. The thermal effects on time and the rate larval development, immature survival and adult size in local populations of Ochlerotatus albifasciatus (Macquart) (Diptera: Culicidae) from cold (Sarmiento)...
