Figure 1

Graphical description of the mathematical model describing sporogonic development within the mosquito prior to the introduction of an intervention. The model charts the number of macrogametocytes, $L_i^1$, ookinetes, $L_i^2$, oocysts, $L_i^3$, and salivary gland sporozoites, $L_i^4$, within mosquito i. For a full list of notation see Additional file 1. The graphs under each arrow indicate the density-dependent processes describing the number of parasites which develop into the subsequent life-stage. Shaded areas indicate the 95% confidence intervals for the best-fit model fitted in [2].
