Interaction plot of the development time and survival of the immature stages of An. stephensi under constant compared with fluctuating temperature regimens. (A) Development time (days, solid lines) and survival (percentage, dashed lines) of mosquito immatures until they reached the adult stage at a constant 20 °C and at a mean temperature of 20 °C but with a diurnal temperature fluctuation of ±6 °C (DTR = 12 °C). (B) Data from an equivalent experiment at 27 °C. Results are given for three different larval densities (■, 0.5, ▲, 1, and •, 2 larvae/cm²). Error bars equal the SEM.
