Impact of Diurnal Temperature Fluctuations during Larval Development on Adult Life History Traits and Insecticide Susceptibility in Two Vectors; Anopheles gambiae and Aedes aegypti
Abstract
Mosquito breeding habitats are exposed to diurnal fluctuations in temperature that developing mosquito larvae must endure. Despite this, work is lacking on what, if any, influence these fluctuations have on adult traits of epidemiological interest. In this work, cohorts from two geographically isolated strains of Aedes aegypti (TH from Thailand and BZ from Belize) and a susceptible (G3) and resistant (AKRON) strain of Anopheles gambiae, were exposed as larvae to one of four diurnal temperature range (DTR) treatments from 0C to 20C around a mean of 28C. Increasing DTR reduced egg production in the TH strain, but increased production in the BZ strain of Ae. aegypti. For An. gambiae, increasing DTR decreased egg production with production ceasing altogether at 20C DTR.
