Figure 2

Degree of melanisation of the beads injected into adult Anopheles gambiae according to larval treatments. The mosquitoes were inculated 4 days after emergence, and beads were recovered 24 h after the injection. The figure shows the amount of melanin deposited on beads (unmelanised beads are excluded). A grey value of 0 would mean that the bead is unmelanised, while a grey value of 256 means that the bead is black and thus completely melanised. The two pictures on the left give examples of an unmelanised (bottom left) and melanized (top left) bead. The sample sizes are, from left to right: N = 95, N = 107, N = 96, and N = 101. Error bars show the 95% confidence intervals of the means.
