From: An elaborated feeding cycle model for reductions in vectorial capacity of night-biting mosquitoes by insecticide-treated nets

Figure 4

Effect of bednet loss of efficacy over time a) Increase in mosquito life span, b) Reduction in duration of the feeding cycle, and c) Increase in proportion of bites on humans (Q), and d) Increase in vectorial capacity, as a function of ITN efficiency over time (successful feeding rate s increases linearly from 0.1 to 0.6 over time and death rate d when landing on ITNs decreases from 0.3 to 0.05 over time) for the anthropophilic species Anopheles gambiae s.l. (N) in Nigeria for 3 different values of ITN coverage φ: low ITN coverage (φ = 10%; light blue), medium ITN coverage (φ = 50%; blue line), high ITN coverage (φ = 90%; dark blue line). The red dashed line corresponds to the standard reference when no ITNs are used.
