Figure 3From: An affordable, quality-assured community-based system for high-resolution entomological surveillance of vector mosquitoes that reflects human malaria infection risk patternsDensity-dependence of alternative ITT-based survey methods relative to the HLC-based QA surveys for sampling Anopheles gambiae s.l. (A and C) and Culex spp. (B and D). The density-dependence is illustrated by plotting the catches from alternative methods divided by the corresponding sum of catches from QA-ITT and QA-HLC or both against the absolute CB-ITT catches.Back to article page
