In 2008, an outbreak of yellow fever occurred in Abidjan. The entomological investigations confirm that Abidjan is at risk of yellow fever with a suspicion of the National Park of Banco (NPB) forest as a likely area of re‐emergence. 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 of Aedes sampled, Aedes aegypti and Aedes africanus were the potential vectors of arboviruses. Both species were collected in Sagbé but only Ae. aegypti in Andokoi. Only Ae. 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 Sagbé and Andokoi. In the NPB forest, however, Ae. africanus has been the predominant species. The study showed the presence of Ae. aegypti in Andokoi and Sagbé. However, Ae. africanus was found in the NPB forest and in the 200 m radius in Sagbé. The establishment of an entomological surveillance program in all areas would therefore be essential for the prevention of arboviruses outbreaks in Abidjan.

非洲的伊蚊（Diptera：Culicidae），是虫媒病毒的锦囊化媒介，已扩展到科特迪瓦阿比让的城市环境。

2008年，阿比让爆发了黄热病。昆虫学调查证实，阿比让有黄热病的危险，因为他怀疑银行国家公园（NPB）森林可能会重新出现。这项研究旨在评估树木虫媒病毒从NPB森林到周围地区（Andokoi和Sagbé）的分散情况。采样是在雨季使用WHO陷阱技术进行的。在六种伊蚊中，埃及伊蚊和非洲伊蚊是虫媒病毒的潜在载体。这两个物种都收集在Sagbé，但只有Ae。安多科伊的埃及。只有爱 埃及它们在距NPB森林400和800 m处存在，但在200 m处，它们在萨格贝和安多科伊的比例分别为75.5％和87.5％。然而，在NPB森林中，Ae。非洲人一直是主要种类。研究表明存在Ae。伊蚊在Andokoi和Sagbé。然而，阂。非洲种是在NPB森林和在Sagbé200米半径找到。因此，在所有地区建立昆虫学监测计划对于预防阿比让的虫媒病毒暴发至关重要。
