Mosquito

Partner study description

Samples were contributed from pyrethrum spray collections, larval sampling and human landing catches conducted in twenty locations during October 2013. These villages are scattered throughout the country and reflect a gradient of human-dominated environments, for example, forest (Manda (5.726, 10.868) and Campo (2.367, 9.817)); forest/savanna transition (Tibati (6.469, 12.629)); savanna (Lagdo (9.049, 13.656)); suburban area (Nkolondom (3.972, 11.516)) and urban areas (Douala (4.055, 9.721) and Yaoundé (3.880, 11.506)). Contributed specimens were An. gambiae or An. coluzzii (1). Population genomics studies indicated the presence of relatively differentiated subgroups within both species as well as clusters thriving in polluted breeding sites in large cities (2). Specimens were stored on silica gel. DNA was extracted using a Zymo research kit for adults, and a Qiagen kit for larvae.
