ResumeThe current study aims to establish the cartography of deltamethrin resistance in malaria vectors from 2010 to 2020 in Republic of Benin. An. gambiae s.l. populations were collected from March to July during the great rainy season in Ouémé in 2010, Littoral in 2012, Atlantic in 2012, Couffo in 2020 and Collines in 2012. An. gambiae s.l. populations were also collected from May to October during the rainy season in Alibori in 2012 and in 2015. Susceptibility tests were done following WHO protocol on unfed females’ mosquitoes aged 2-5 days old reared from larval and pupal collections with papers impregnated with deltamethrin (0.05%). The results showed that the populations of Anopheles gambiae s.l. from Adjara, Dangbo and Missérété were resistant to deltamethrin in 2010 whereas the populations of Anopheles gambiae s.l. from Kandi, Malanville, Cotonou, Allada and Dassa-Zoumè were resistant to this product in 2012. The populations of Anopheles gambiae s.l. from Parakou were resistant to deltamethrin in 2015 whereas the populations of Anopheles gambiae s.l. from Dogbo were resistant to the same product in 2020. The establishment of mapping or geographic distribution of deltamethrin resistance in malaria vectors from 2010 to 2020 in Republic of Benin is useful as this will properly inform control programs of the most suitable insecticides to use and facilitate the design of appropriate future resistance management strategies.
