Location of the five sampling locations. The zone with the grids (each cell is 5*5 km) corresponds to the tsetse eradication area. Blocks were tackled sequentially in two phases, i.e. a suppression phase using insecticides and an eradication phase with the sterile insect technique (see text for details). The monitoring of ecological indicators thus followed a stepped wedge approach as shown in the table.
