Abstract: This study evaluates the susceptibility of vectors to deltamethrin, chlorfenapyr (CFP) and clothianidin (CTD) in different agro-ecological zones of the country. Populations of An. gambiae s.l. derived from larvae collected between April and September 2022 in 04 cropping zones: vegetable, cereal, rice and cotton were exposed to deltamethrin, chlorfenapyr and clothianidin. Biochemical and target-modification resistance mechanisms were detected in a sample of each mosquito population. All populations of An. gambiae s.l. tested with deltamethrin showed mortality that varied between 9 and 60%. Overall, the mean frequency of the kdr L1014F mutation across all localities was 86% followed by overproduction of detoxification enzymes. As for the new insecticides, the mortality rate was 98%-100% for the CFP and for the CTD regardless of the locality and the agro-ecological zone tested. Chlorfenapyr and clothianidin are viable alternatives that could be used for improved control of pyrethroid-resistant populations of An gambiae s.l.
