This study was carried out in Alimosho, Kosofe, Ibeju-Lekki and Badagry Local Government Areas (LGAs) of Lagos State to assess the susceptibility status of Anopheles gambiaes.l., a dominant malaria vector in the localities to DDT 4% and Permethrin 0.75%. Anopheles larvae were collected from larva habitats in both LGAs, reared to adults and fed with 10% sucrose solution. Non-blood fed 2-5 days old female mosquitoes were exposed to discriminating doses of DDTand permethrin according to the standard WHO procedures.
