Abstract: 
The current study aimed to investigate on the control tools against larvae and adults of Anopheles gambiae s. l. and then explore the detoxification enzymes mechanisms conferring permethrin tolerance in Anopheles gambiae s. l. larvae in Benin. Larvae and pupae were collected from March to July and August to November 2018 during the rainy season in Bopa district in Mono department in south-western Benin, West Africa. Larval bioassays were performed on these collected Anopheles gambiae s. l. larvae using permethrin as larvicide and synergist piperonyl butoxide (PBO) as enzyme inhibitor or synergist. WHO susceptibility tests were also conducted on adult unfed female mosquitoes aged 3-5 days old with impregnated papers of permethrin (0.75%). The results showed that malaria elimination in Benin needs integrated control. Both larvae or pupae and adults malaria vectors must be controlled.
