The trophic behavior of Aedes aegypti at Dandji, a neighbourhood of Cotonou located in southern Benin was evaluated trough a cross-sectional study where adults of Ae. Aegypti populations were collected from May to July 2022 daily twice a week by Human Landing Catch and BG-Sentinel traps. From the total of 717 Aedes collected by different methods, Ae. Aegypti is more abundant in urban than peri-urban areas (p<0.05). The aggressive density of Ae. aegypti populations was significantly higher in urban areas (102.89 bites per man per hour) than in peri-urban areas (52.85 bites per man per hour) (p<0.05). Also, out of 160 females blood-fed Ae. Aegypti tested by ELISA (Enzyme Linked Immunosorbent Assay) technique for blood meal identification, 90% took their blood meal on humans compared to 6.5% which took their blood meal on sheeps. These findings showed that the neighbourhood Dandji in southern Benin offered good condition for the development of Ae. aegypti populations. The anthropology and endophagy behavior of Ae. aegypty observed from this study need to be considered as a tool to control this mosquito.

Abstract: (french)
Afin d’évaluer le comportement trophique du moustique Aedes aegypti dans le quartier de Dandji à Cotonou au sud du Bénin, une étude a été conduite dans les quartiers urbains et periurbains de Mai à Juillet 2022. Ces collecttes ont été faites à partir des captures sur appat humain et de pièges BG-Sentinel deux fois par semaine pendant la durée de l’étude. Les résultats des collectes ont montré que sur un total de 717 issus de deux méthodes, la population de Ae. Aegypti était plus importante en zone urbaine que peri-urbaine. La densité agressive des populations de Ae. aegypti a été significativement plus importante dans la zone urbaine (102,89 piqûres par homme par heure) qu’en zone périurbaine (52,85 piqûres par homme par heure) (p<0,05). Aussi, sur 160 femelles de Ae. Aegypti gorgées et testées à l’ELISA (Enzyme Linked Immunosorbent Assay), 90% ont pris leur repas sanguin chez l’homme contre 6,5% qui ont pris leur repas sur les moutons. Ces résultats montrent que le caractère anthropo-endophage de ce moustique constaté à travers les résultats de cette étude constitue un indice très dans la strategié de lutte contre ce moustique.
