The location of the 55 fixed monitoring sites is presented (red points).

Figure 2. Entomological, epidemiological, and socioeconomic indicators of the eradication campaign on the island of Unguja.
Graph (A) presents the rate of induced sterility (4-week moving average). Graph (B) shows the density of tsetse flies sampled with the sticky panels in fixed monitoring sites. The trap catches (+0.001) of indigenous female (dotted red line) and male (solid blue line) G. austeni are presented on a logarithmic scale. Graph (C) presents the decrease in trypanosome prevalence as a result of tsetse eradication. Graph (D) presents the percentage of farmers owning cattle and improved cattle breeds, and graph (E) presents the increase in milk production per cattle head (in liters) and in the percentage of farms producing milk.
