Volatile chemicals collected from virgin Eurytoma amygdali females by extracting the whole or parts of their bodies in methylene chloride were attractive to males in laboratory bioassays. The same attraction was found when volatile compounds were collected by the SMPE fibre. Comparative GC-MS analysis of male and female extracts indicated differences which corresponded to a number of peaks present only in the female extract. Preparative GC fractionation of these peaks and subsequent bioassays elicited male response. These peaks correspond to mono-unsaturated and di-unsaturated long chain hydrocarbons as indicated by mass spectrometric analysis
