Abstract
Several countries in tropical Africa, including Côte d'Ivoire, are
affected by malaria. To prevent this disease, vector control measures including
the use of LLINs is recommended. In this context, the Ivorian government has
initiated national mass distribution campaigns of LLINs to help control the
densities of malaria vectors and decrease the incidence of malaria. This study
was carried out to investigate the resting behaviour and host preference of
malaria vectors particularly An. Gambiae in Man and Abengourou, two
areas of Côte d’Ivoire. In 2015 and 2019, after spraying insecticide in
selected houses in the morning, indoor resting anopheline mosquitoes were
sampled in urban and rural areas during the dry and rainy seasons in the two
sites. The origin of blood meals of the mosquitoes from these collections was
then investigated using the blood meal ELISA technique. The culicidian fauna
inventory showed a diversity of mosquitoes (Anopheles, Aedes, Culex and
Mansonia) with the predominance of the An. Gambiae species in each
locality except the urban area of Man where the Culex genus
predominated. The feeding behaviour of An. Gambiae in Man was more
diverse in 2015 than those harvested in 2019, which are anthropophilic. In
Abengourou, the behaviour of An. Gambiae remained unchanged from 2015 to
2019. The results show that in areas of massive distribution of LLINs, feeding
behaviour of An. Gambiae can undergo changes.
