Population level effectiveness of new and aged nets, depending on mortality in WHO susceptibility tests. First column of panels (a &c) for intact new nets, second column of panels (b &d) for 20 times washed nets with a holed area of 96 cm². The first row of panels (a, b) shows population level protection against feeding of mosquitoes if 70% of the human population uses a net. The second row of panels (c, d) shows the corresponding population level insecticidal effectiveness, as defined by Briët and colleagues [18]. Circles and triangles represent estimated values for PermaNet 3.0 and PermaNet 2.0, respectively. Colours represent mosquito populations 1–9 in Table 1, with black: ‘Akron’, red: ‘Yaokoffikro’, lime green: ‘Kou’, orange: ‘Van Duc A’, dark blue: ‘Pitoa’, cyan: ‘New Bussa AG’, magenta: ‘Malanville’, yellow: ‘Zeneti’, and grey: ‘New Bussa AA’. Adjusted R² values were calculated using linear regression on logit transformed proportions.
