Abstract

In addition to the major component, 2-methyl- 6-vinylpyrazine, 2,5-dimethyl-3-vinylpyrazine was collected as a minor component from calling male papaya fruit flies Toxotrypana curvicauda Gerstaecker (Diptera: Tephritidae). Volatile chemicals emitted by calling males were identified by gas chromatography/mass spectrometry detector analyses. Attraction response was verified by wind tunnel bioassays for the male volatile collections and for both synthetic pyrazines. The percentages of attraction to the source caused by each pyrazine were similar to those caused by the male volatile collection; however, only a blend of the pyrazines resulted in a similar percentage of landings on the source.
