Small animals like nematodes and insects analyze airborne chemical cues to infer the direction of favorable and noxious locations. In these animals, the study of navigational behavior evoked by airborne cues has been limited by the difficulty of precise stimulus control. We present a system that enables us to deliver gaseous stimuli in defined spatial and temporal patterns to freely moving small animals. We use this apparatus, in combination with machine vision algorithms, to assess and quantify navigational decision-making of Drosophila larvae in response to ethyl acetate (a volatile attractant) and carbon dioxide (a gaseous repellant).
