∗Superscripted numbers represented the number of 3-5-day-old female mosquitoes assayed. −Where 3-5-day-old female mosquitoes were not available for exposure to that particular insecticide. WHO criteria for susceptibility are as follows: mortality rates between 98% and 100% indicate full susceptibility; mortality rates between 90% and 97% require further investigation while mortality rates < 90%, the population is considered resistant to the tested insecticides.
