Urban malaria is an emerging challenge in sub-Saharan Africa, driven by unplanned urbanization, irrigation, and vector adaptation; yet data on urban vectors, their diversity and malaria transmission potential are limited. We assessed Anopheles gambiae s.l. abundance, species composition, and behavior in Accra, Ghana, during dry and rainy seasons of 2022 to 2024 across fifteen sites representing different socioeconomic settings. A total of 20,945 host-seeking and 1,613 resting Anopheles mosquitoes were collected. Abundance was highest in irrigation and peri-urban sites, and lowest in low socioeconomic areas. An. gambiae s.s. dominated host-seeking populations, while An. coluzzii dominated resting ones. Findings highlight irrigation and peri-urban areas as hotspots, requiring targeted surveillance and control.
