Predicted impact of increasing levels of deterrence ( θ
) upon underlying biodemographic mosquito and sprogonic-stage parasite population parameters that determine malaria transmission for LLIN or IRS products with ( θ
= 0.5, θ
= 0) and without ( θ
= 0, θ
= 0) toxic properties at 80% crude coverage ( C
= 0.8). Only the model with survival-dependent emergence rates ( E ) is presented.
