Diel activity patterns of mosquito vector populations.
(A) Total number of female adult mosquito specimens collected over the entire study period by hour of collection in Brownsville, Texas. The figure reports vector mosquito species only; S1 Fig shows all the collected species. The Dominance Index is shown in black (mean and 95% CI). (B) Same as A, but for Miami-Dade County, Florida.

Effectiveness of adulticide application twice per day for five consecutive days by hour of application.
(A) Maximum reduction (%) of the number of mosquitoes following adulticide application by hour of application in Brownsville, Texas. Adulticide was applied twice per day (within the same hour) for five consecutive days. The maximum reduction is obtained after the fifth day of insecticide application; after that, the mosquito population starts to recover. Lines represent mean values, which are obtained by averaging over 1,000 stochastic model realizations. Bar plots show mean and 95%CI of the same metric for adulticide application at 2 PM and 9 PM. Spraying efficacy is set at 50%. (B) Same as A, but for Miami-Dade County, Florida. (C) Number of days after the end of the adulticide application it takes for the mosquito population to recover to the pre-intervention level by hour of adulticide application. Adulticide was applied twice per day (within the same hour) for five consecutive days. Lines represent mean values, which are obtained by averaging over 1,000 stochastic model realizations. Bar plots show mean and 95%CI of the same metric for adulticide application at 2 PM and 9 PM. Intervention efficacy is set at 50%. (D) Same as C, but for Miami-Dade County, Florida.

Effectiveness of adulticide application once per week for two months by hour of application.
(A) Average reduction (%) of the number of mosquitoes following adulticide application by hour of application in Brownsville, Texas. Adulticide was applied once per week for two months. Averages are calculated over the 2-month duration of the intervention. Lines represent mean values, which are obtained by averaging over 1,000 stochastic model realizations. Bar plots show mean and 95%CI of the same metric for adulticide application at 2 PM and 9 PM. Insecticide efficacy is set at 50%. (B) Same as A, but for Miami-Dade County, Florida.
