Exposure device with live host to test repellent effect of different compounds on Rhodnius prolixus and Triatoma infestans. Drawing not to scale. A polystyrene tube (10.0 × 1.7 cm, length × diameter, respectively) was divided in three zones: host, intermediate and refuge zone. At the end of the host zone a mesh allows transmission of stimuli released by the host (including VOCs alone or with repellent compounds), but avoid that insects could bite the host
