abstract
The aim of the present study was to determine the dynamics of malaria transmission and the sensitivity of its vectors in order to better plan vector control programme. Mosquitoes captured on volunteers, from September 2019 to June 2020, at the rythm of 2 consecutive nights every three months, were identified according to morphological and molecular criteria. The infectivity of the vectors was determined by the ELISA CSP test. Insecticide susceptibility was assessed and resistance mechanisms were determined. The anopheles genus (64.07%; n=6020) was the most represented and An. gambiae, responsible for 82.61% of transmission in both sites, followed by An. funestus s.l. (17,39%). The average entomological inoculation rates were 2.03 ib/p/n at Njombé and 0.48 ib/p/n at Bonandam. Diagnostic PCR for resistance genes detected the presence of the kdr L1014F mutation in the natural population of An. gambiae s.l. High insecticide resistance requires the development of new mosquito control formulations.
