Impact of variable temperatures on the critical maximum temperature. Survival of Anopheles stephensi mosquito immatures at various mean temperatures (x-axis) and daily temperature ranges (DTRs) of (a) 8 °C, (b) 12 °C, or (c) 16 °C. Note that rCTmax is lower than the fundamental CTmax of 36 °C in a constant environment (Fig. 2b). (d) Effect of smaller DTRs around a mean temperature of 35 °C. Vertical error bars represent the standard error of the mean.
