Efficacy (mortality) over time of indoor residual spraying of the WP and WG formulations of Alphacypermethrin against susceptible An. gambiae. Mortality rates were predicted from a binomial-response mixed effect model. Formulation WP (blue lines) and WG (black lines) at the 20 mg/m2 (a, b; solid lines) or 30 mg/m2 (c, d; dashed lines) targeted dose applied on mud (a, c) or cement walls (b, d) are compared. Grey areas are 95% confidence interval of predicted means. Mortality values measured on the field and used to fit the regression model are shown as blue squares (WP) and black circles (WG) of size proportional to the number of values (max = 20)
