Mosquitoes of the genus Aedes are major vectors of
arboviruses of global public health importance and rank among the most invasive
insect species, with their spread closely associated with international trade
and transport. Entomological surveillance initiated in 2009 as part of
strengthened epidemiological monitoring detected the presence of Aedes
albopictus at the Port of Abidjan. To assess the population dynamics of Aedes
mosquitoes and the associated health risks, a study was conducted from April to
December 2014, combining ovitrap monitoring at ten-day intervals with monthly
larval surveys. All adults emerging from ovitraps were identified as Aedes
aegypti. Oviposition site selection was influenced by surrounding vegetation
and the intensity of human activity. The larval habitats identified were
dominated by tarpaulins and used tyres, habitats linked to port logistics and
cargo handling. Aedes aegypti infested most positive breeding sites, with
tarpaulins and cavities in concrete poles representing the most productive
habitats. These findings indicate that port environments function as critical
interfaces between local transmission and the international dissemination of
vectors and arboviruses. They underscore the need to integrate entomological
surveillance and control of artificial breeding sites into port biosecurity
strategies to prevent the introduction, establishment, and export of vectors,
in line with global health security priorities and the implementation of the
International Health Regulations.
