Abstract
The electroantennogram method was used to investigate the number of distinc t olfactory receptor neuron types responding to a range of behaviorally act ive volatile chemicals in gravid Queensland fruit flies, Bactrocera tryoni. Three receptor neuron types were identified. One type responds to methyl b utyrate, 2-butanone, farnesene, and carbon dioxide; a second to ethanol; an d a third to n-butyric acid and ammonia. The receptor neuron type respondin g to methyl butyrate, 2-butanone, farnesene, and carbon dioxide consists of three subtypes. The presence of a limited number of receptor neuron types responding to a diverse set of chemicals and the reception of carbon dioxid e by a receptor neuron type that responds to other odorants are novel aspec ts of the peripheral olfactory discrimination process.
