Most mosquitoes that serve as vectors of the Yellow Fever virus in Africa and in South America use as their larval habitats tree-holes that can trap rainwater. The dynamics of these populations are thus highly dependent on climate. To describe this process, we developed two models simultaneously: the first simulates the evolution of the rainwater trapped in the treeholes as a function of the rain patterns, and the second, a five-stage (immature egg, mature egg, larva, nulliparous female, parous female) structured population model, includes the influence of this trapped rainwater. The final model reproduces the fluctuations of a population of Aedes africanus observed over three consecutive years in Côte d’Ivoire and may help to study other species of arbovirus vectors in various bioclimatic zones.
