Life history traits measured for Ae. aegypti mosquitoes reared at 13°C, 15°C, 19°C, 23°C, 25°C, 27°C, 29°C, 31°C, 33°C, 35°C, 37°C.
We measured life history traits for five populations from Mexico (Cabo San Lucas (yellow), Acapulco (pink), Monterrey (orange), Ciudad Juárez (red), and Jojutla (blue)) compared to a laboratory adapted line (shown in green). The data points for figures are the values from three replicates for each corresponding population at each temperature with individual values for adult survival and fecundity along with mean values for each replicate for biting rate, mosquito development rate and egg-to-adult survival probability. Thermal performance curves for life-history traits for the six populations were fit using Bayesian inference with weakly informative priors are shown (Model values can be found in Tables B-F in S1 Appendix). Each mosquito line was tested between 13°C-37°C, but individuals did not survive and reproduce at 13°C and 37°C. A) Egg-to-adult survival measured as the probability of individuals surviving to the adult stage. B) Mosquito development rate is the inverse of the amount of time that it takes to reach the adult stage. C) Fecundity is measured as individual egg production for the first gonotrophic cycle. D) Model fits for approximated biting rate (1/gonotrophic cycle length). E) Model fits for estimated mean adult survival (in days) derived from measures of daily survival of adults over 28 days post initial blood meal, censored individuals are clustered at the last day tested.

Temperature-dependent fitness (intrinsic rate of increase, rm) derived from individual life-history traits measured for Ae. aegypti mosquitoes reared at 13°C, 15°C, 19°C, 23°C, 25°C, 27°C, 29°C, 31°C, 33°C, 35°C, 37°C.
We measured life history traits for five populations from Mexico (Cabo San Lucas (yellow), Acapulco (pink), Monterrey (orange), Ciudad Juárez (red), and Jojutla (blue)) compared to a laboratory-adapted line (shown in green). The lines indicate mean model fits. Fits for individual populations that include the credible intervals and values are presented in Fig C and Table H in S1 Appendix.
Fig 3.
Summarized values for thermal performance curves for each population showing the relationship between (a) breadth of the curve (Tbreadth) and maximum performance (Pmax).
Pearson’s correlation indicates significant strong positive relationship between Pmax and Tbreadth (r = 0.882) and Pmax and Topt (r = 0.861).

Temperature-dependent relative R0 (transmission rate as the basic reproduction rate R0) derived from individual life history traits measured for Ae. aegypti mosquitoes reared at 13°C, 15°C,19°C, 23°C, 25°C, 27°C, 29°C, 31°C, 33°C, 35°C, 37°C.
We measured mosquito life-history traits for five populations from Mexico (Cabo San Lucas (yellow), Acapulco (pink), Monterrey (orange), Ciudad Juárez (red), and Jojutla (blue)) compared to a laboratory-adapted line (shown in green). The lines indicate mean model fits. Fits for individual populations that include the credible intervals and model summary values are presented in Fig D and Table I in S1 Appendix.
