Abstract
Single-unit electrophysiology was used to record the nerve impulses from th e carbon dioxide receptors of female Queensland fruit flies, Bactrocera try oni. The receptors responded to stimulation in a phasic-tonic manner and al so had a period of inhibition of the nerve impulses after the end of stimul ation, at high stimulus intensities. The cell responding to carbon dioxide was presented with a range of environmental odorants and found to respond t o methyl butyrate and 2-butanone. The coding characteristics of the carbon dioxide cell and the ability to detect other odorants are discussed, with p articular reference to the known behavior of the fly.
