Cd. Hull et Bw. Cribb, Olfaction in the Queensland fruit fly, Bactrocera tryoni. I: Identification of olfactory receptor neuron types responding to environmental odors, J CHEM ECOL, 27(5), 2001, pp. 871-887
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.
