Man, in a desperate bid to manage malaria-vectors, i.e., Anopheles gambiae s.l. (Diptera: Culicidae) has relentlessly relied on pyrethroid insecticides especially permethrin. Unfortunately, these mosquitoes have improved their survival with respect to this tactic which must have been associated with some fitness-costs. This study, therefore, evaluates the biological fitness-costs associated with permethrin-resistance development in An. gambiae s.l. in Kwara State, Nigeria. Susceptibility statuses of adult female An. gambiae s.l. populations collected from Oke-odo, Pipeline and Airport were established using World Health Organization Protocol. They were subsequently raised over three-generations and the fecundity, hatchability, development time for larvae, pupae and adult, adult emergence, the adult sex ratio was observed, noted, monitored and analysed using ANOVA (P
