The venom of the queen common wasp, Vespula vulgaris was examined by Gas chromatography/electroantennographic detection (GC/EAD) and Gas Chromatograph/Mass Spectrometer (GC/MS). Two compounds from the queen venom consistently elicited an antennal response in both males and workers. The two compounds were synthesised and their identity positively confirmed by GC/MS analysis on two different capillary columns. One of these compounds is novel and described for the first time from any source. These compounds were tested in field trapping trials in a beech forest for the attraction and repellence of social wasps. Results will be discussed in this presentation.
