Community protective effects of 80 % bednet use coverage depending on the holed surface area on three mosquito species. The first column of panels a–c is for An. gambiae KISUMU strain, the second column of panels d–f is for An. gambiae collected in Akron, and the third column of panels g–i is for Cx. quinquefasciatus collected in Cotonou. The first row of panels a, d, g shows the community protection against feeding assuming that 80 % of the population uses a net (see "Appendix"), the second row of panels b, e, h shows the community insecticidal effectiveness, and the third row of panels c, f, i shows protection against transmission (note that this is theoretical for Cx. quinquefasciatus, as it is not a competent malaria vector).
