Cumulative Anopheles gambiae s.l. adult female captures and rainfall during rainy seasons of 2005, 2006 and 2007. Cumulative adult female An. gambiae s.l. captures from the sum of all six CDC miniature light traps are shown by the solid lines, with crosses to mark the dates of each trap deployment, and the numbers captured are recorded along the left-hand axis. Cumulative rainfall is shown by the dashed lines, updated hourly, and is recorded along the right-hand axis. The cumulative data represent the integral over time of the data shown in Figure 3. For both data sets, 2005 data is in blue, 2006 data is in red and 2007 data is in green.
