Excito-repellent flight behavior in permethrin-resistant and surgically altered Puerto Rican Aedes aegypti exposed to insecticide-treated fabric

Insecticide resistance is an emerging public health issue brought on by increased reliance on fewer classes for chemical control. This study examines the behavioral differences in the landing and flight activity for select populations of Puerto Rican Aedes aegypti after their exposure to four pyrethroid-treated uniform fabrics. The populations were made up of both susceptible and pyrethroid resistant strains of Aedes aegypti, with half of each population surgically altered with the antennae bilaterally amputated with fine forceps. We examined various aspects of flight behavior, including the time to first take-off (TFF), number of landings (NOL), cumulative flight time (TFT), and maximum time in contact with the surface (MSC) by video analysis.
