Table 4 Spatial clusters (foci) of An. farauti densities within Jack Harbour, New Mala and Haleta villages as well as An. hinesorum in Kinamara village and An. lungae in Saeragi village

From: Spatial-temporal heterogeneity in malaria receptivity is best estimated by vector biting rates in areas nearing elimination
