Locations: Bioko Island, Equatorial Guinea (GQ)

Partner study description

Collections were performed during the rainy season in September 2002 by overnight CDC light traps in Sacriba of Bioko island (3.7, 8.7). Specimens were stored dry on silica gel before DNA extraction. Specimens contributed from this site were An. gambiae females, genotype determined by two assays (1, 2). These mosquitoes represent a population that inhabited Bioko Island before a comprehensive malaria control intervention initiated in February 2004 (3). After the intervention An. gambiae was declining, and more recently almost only An. coluzzii can be found (4).
