Figure 5. Efficacy of triatomine lethal traps according to their potential attractiveness and density in the village.

Efficacy was measured as a percentage reduction in vector abundance in the whole village, when traps were installed all across the village. Attractiveness was increased from H_trap = 1, where traps are not attractive since they had the same H factor as peri-domiciles, to H_trap = 50. Symbols stand for different density of traps. Open circles: 1 trap for 10 houses, open squares: 1 trap for 5 houses, open diamonds: 1 trap for 2 houses, closed triangles: 1 trap per house, closed diamonds: 2 traps per house and closed squares: 5 traps per houses.
