(a) Prevalence curves of human (I h : solid line) and mosquito (I m : dashed line) populations in Ross (RR), Macdonald (MC) and Anderson-May (AM) models. Parameters used are: a = 0.2 day-1 , b = 0.5, c = 0.5, m = 20, r = 0.01 day-1, μ 1 = 0.017 year-1, μ 2 = 0.12 day-1, τ m = 10 days, τ h = 21 days. (b) Variation of basic reproductive number (R 0 ) with mosquito biting rate (a) and mosquito mortality rate (μ 2 ) in Ross model (grey surface) and Anderson-May model (black surface). The surface of R 0 = 1 is shown as gridded white plane.
