Overall insecticidal effect quantities depending on mortality in an experimental hut with an intervention. The proportion deterred from entering δ is kept constant at 0.4, and the proportion dead out of those that entered into an untreated control hut μ0⋆ is kept constant at 0.20. Also, the proportion repelled (unfed alive mosquitoes) out of those entered is kept constant at ρ
= 0.3 and ρ
= 0.1 for treated and control huts, respectively. μ
⋆ is the proportion of mosquitoes dead in an experimental hut out of those that entered. Lines are drawn for μ
⋆ ≥ μ0⋆.
