Figure 2.

Species and molecular form composition in the four villages over time, based on 4,584 mosquitoes which were successfully genotyped to species and molecular form (see text for details). Note that the time intervals are variable. Pooling of adjacent dates was carried out if samples were small and only if minimal differences in composition were found. Except for the period marked '2Feb10' that covered samples from January to March, other pooled samples represent periods shorter than three weeks between June and October 2010. Numbers above bars show cases where sample size per village/period were smaller than 20. Significant heterogeneity among villages (P < 0.05, after the sequential Bonferroni procedure) is denoted by stars.
