Figure 9

Correlation between cumulative Anopheles gambiae s.l. captures and cumulative rainfall for 2005, 2006 and 2007 in Zindarou. The figure depicts cumulative mosquito captures in Zindarou plotted against cumulative rainfall on a log-linear axis. The data points represent the cumulative rainfall, calculated from June of a given year until the time of a mosquito sampling event, and the cumulative anopheline mosquito captures in a given year up to the time of that event. For each year, the data points were divided into four bins of equal sample size. 12 data points were in each bin for the non-intervention years of 2005 and 2006 and 6 data points were in each bin for the intervention year of 2007. The mean and standard deviation of both the cumulative rainfall and cumulative mosquito captures were calculated within each bin for each year. 95% confidence limits were calculated with a t-distribution and are shown as the error bars around each data point. The combined 2005 and 2006 data is shown in blue and 2007 data is shown in green.
