Gas chromatography-Fourier transform infrared spectroscopy has been used to analyze preconcentrated headspace samples of the volatile mixture emanating from the intact fruit of Coffea arabica. Among the components identified were carbon dioxide, ethyl acetate, ethanol, isovaleraldehyde, water, 3-methyl-1-butanol and 3-hydroxy-2-butanone.
A list of ten fruit fly hosts was kindly provided by P. G. Snyder of the Port Operations Staff, Animal and Plant Health Inspection Service, U.S. Department of Agriculture.
