Fitted Mosquito Density (solid black) versus observed density (dashed black). Also shown are the input rainfall (blue) and temperature (red) data. Observed mosquito density was adapted from Azil et al. using data from BG traps . Note that mosquito density is presented without a scale since it is the relative mosquito density which scales to an absolute mosquito density by adjusting Lmax, as described in the Additional file 1.
