Figure 6

Scatter plots comparing the spatial clustering of Anopheles gambiae s.l. and Anopheles funestus densities with distance from the village centre. Spatial clustering is represented by the species specific Getis-Ord Gi* Z Score calculated for each household; clusters of households with high densities were identified with Z scores >1.96 (shaded area at top), or vice versa, clustered households with low densities of anophelines were identified with Z scores < −1.96 (shaded area at bottom).
