Expansion of Aedes africanus (Diptera: Culicidae), a sylvatic vector of arboviruses, into an urban environment of Abidjan, C ôte d'Ivoire

This study aims to assess the dispersion of sylvatic vectors of arboviruses from the NPB forest to the surrounding areas (Andokoi and Sagbé). The sampling was done in the rainy season using the WHO layer‐traps technique. Among the six species ofAedes sampled,Aedes aegypti andAedes africanus were the potential vectors of arboviruses. Both species were collected in Sagb é but onlyAe. aegypti in Andokoi. OnlyAe. aegypti were present 400 and 800 m from NPB forest, but at 200 m, it showed respective proportions of 75.5% and 87.5% in Sagb é and Andokoi. In the NPB forest, however,Ae. africanus has been the predominant species. The study showed the presence ofAe. aegypti in Andokoi and Sagb é. However,Ae. africanus was found in the NPB forest and in the 200 m radius in Sagb é. The establishment of an entomological surveillance program in all areas would therefore be essential for the prevention of arboviruses outbreaks in Abidjan.
