Temperature history profiles of mosquitoes exposed to A) malathion or B) permethrin. All adults were reared under standard 26°C conditions. Up to one hour prior to exposure, females in each treatment group were moved to their exposure temperatures to adjust to the holding tubes; they remained at these temperatures throughout and after their hour-long insecticide exposure. After 24 hours at their treatment temperature, mosquitoes exposed to permethrin were moved to 26°C for 15 minutes in order to assess recovery.
