Passive Outdoor Host Seeking Device (POHD): Designing and Evaluation against Outdoor Biting Malaria Vectors

Figure 4

Experimental systems used to evaluate the attractiveness of a passive outdoor host seeking device against An. arabiensis. Experiments were conducted under closed (air-tight) environment using (a) the experimental hut within the SFS and (b) bottle of water surrounded with attractants and treated or untreated netting hanged in the middle of the experimental hut. (c-d) The alive and dead mosquitoes were collected from walls, floors, and roofs of the hut. Other experiments were conducted under free wind movement inside the screened rectangular bioassay box with a complete device hanged in the middle (e).
