Partner study description

Samples were collected in Tiassale (5.898, -4.823), located in the evergreen forest zone of southern Côte d’Ivoire. The primary agricultural activity is rice cultivation in irrigated fields. High malaria transmission occurs during the rainy seasons, between May and November. Samples were collected as larvae from irrigated rice fields by dipping between May and September 2012. All larvae were reared to adults and females preserved over silica for DNA extraction. Specimens from this site were all An. coluzzii, determined by PCR assay (1).
