Current insecticide resistance status in malaria vector populations from Dogbo district in South-western Republic of Benin, West Africa

This study was aimed to investigate thecurrent insecticide resistance status in malaria vector mosquitoes from Dogbo district South-western Benin, West Africa. Larvae and pupae of Anopheles gambiae s.l. populations were collected the breeding sites March July 2020 during first rainy season Couffo department using dipping method. WHO susceptibility tests conducted on unfed female aged 2-5 days old. bioassays performed with impregnated papers permethrin (0.75%), deltamethrin (0.05%), cyfluthrin (0.15%), lambdacyhalothrin (0.05%) dichlorodiphenyltrichloroethane (DDT) (4%). An. gambiaes.l. resistant permethrin, deltamethrin, cyfluthrin, DDT. There is cross-resistance both pyrethroid DDT insecticides. However, physical barrier Long Lasting Insecticidal Nets (LLINs) which are regularly distributed free by Beninese National Malaria Control Programme throughout entire country increase coverage LLINs still important despite observed.
