Fig. 1

Graph showing the relative proportion of malaria vectors across study sites in The Gambia. Asterisks indicated significant differences in species diversity between village pairs assessed using fisher exact tests (where collections and > 1 species collected, permitted test); ***P < 0.001; *P < 0.05 Below it is administrative map of The Gambia showing study sites/villages in 6 geographic regions (numbered). 1 west coast, 2 LRR-N (lower river region-north), 3 LRR-S (lower river region-south), 4 CRR-N (central river region-north), 5/6 URR-S/N (upper river region-north/south). The green dots indicate low malaria prevalence while red dots—high malaria prevalence villages.
