Distribution of Anopheles gambiae complex mosquitoes in Cameroon. Relative abundance of members of the An. gambiae complex collected along a North-to-South transect from 5 August to 8 December 2005. Pies show the frequency of An. arabiensis (grey), An. gambiae M (black) and An. gambiae S (white) in each sampled locality. The area of the circle is proportional to the number of specimens identified. The only other member of the An. gambiae complex present in Cameroon, namely An. melas was collected only from a single locality (Campo, southernmost sampled point along the Atlantic coast), and it is not shown.
