Electroantennogram (EAG) recordings from the antennae of a highly specialized phytophagous species -- the oak flea weevil, Rhynchaenus quercus L. -- revealed two general properties of its antennal olfactory system: (1) a high and to some extent selective sensitivity to chemotaxonomically nonspecific compounds, namely the so-called “general green leaf volatiles” as well as to geraniol and linalool, (2) a lack of marked differences in the general excitation level caused by stimulation with vapours from leaves of both host plants and non-host plants. It was also observed, that the shapes of EAG's evoked by vapours from cut leaves and general green leaf volatiles differed from those elicited by corresponding concentrations of geraniol and linalool, where recovery was distinctly slower. The results of EAG tests suggest that the general green leaf volatile complex is important in host-odour perception by the oak flea weevil. A possible function of these compounds in host-plant odour discrimination is discussed.
