The aim of the study was to describe the bio-ecology of local anopheline vectors, their abundance and type as well as the vectoral competence around three communities. The study sites were selected based on bio-ecologic zones (Atonsu: urban; Emena: peri-urban; and Akropong: rural), which influence Anopheline habitat and behavior. The study was carried out in the period June – August, 2008. The pyrethrum spray catch was used to collect anthropophilic, endophillic anopheline mosquitoes from bedrooms of study communities and identified based on morphological keys described by Gilles and Coetzee (1987) with the aid of stereomicroscope. The blood meal taken and the stage of digestion and egg development were also observed. A total of 293 mosquitoes were collected in all areas and 50.5% were identified as belonging to Anopheles gambiae s.l. For the 103 mosquitoes collected from Atonsu, 53.4% (n= 55) were Anopheles gambiae s.l, 27.2% Culex and 19.4% (n=20) Mansonia. At Akropong, out of the 93 mosquitoes collected, 58% (n=54) were Anopheles gambiae sl and the rest were culicines. At Emena, 40.2% of the mosquitoes collected out of the 97 were found out to be A. gambiae with the rest being predominantly culex pipien s.l. There was no Anopheles funestus found. Over 80% of all Anopheles collected had taken blood meals and have spent some time resting in the bedroom. The findings indicate that Atonsu rather exhibits rural characteristics and can best be described as ‘urban poor’, Emena slightly exhibits city characteristics but the results are not conclusive. The anopheline mosquitoes in the study communities are highly endophillic and anthropophagic and thus have high vectoral competence. Akropong seems to have the characteristics of a rural area in terms of mosquito abundance and malaria susceptibility. It is recommended that entomological data should be collected twice a week for further studies and confirmation.
