Fig. 1From: Grass-like plants release general volatile cues attractive for gravid Anopheles gambiae sensu stricto mosquitoesThe olfactometer bioassay experimental setup. The substrates were placed in the two large (1 × 0.9 × 1 m) chambers (a) from which a 12-V electric fan (b) drew air to the outside. The fan pipe (c) was fitted on the top side and the mosquito release cup at bottom side of the release chamber (d). The mosquitoes that made a directional choice were trapped in either of the two trapping chambers (e) and data were recorded every morning by removing the fan pipe and the trapping chambersBack to article page
