AB Prinobius myardi Mulsant is a wood borer implicated in the decline of Mediterranean oaks, especiallyQuercus suber L. and Quercus ilex L. Plant volatiles play an important role in plant-insectinteractions, and electroantennography (EAG) is an effective tool for exploring the electrophysiologicalactivity of host plant volatiles on insects. To improve our understanding of the olfactorysensitivity of P. myardi, we recorded EAG responses to 20 tree volatiles, and analyzed the dosedependentresponse to five doses (10–4:1 to 1:1 v/v) of the three most EAG-active compounds.Antennae of P. myardi responded to 13 chemicals, mainly monoterpenes and green leaf volatiles,with the strongest EAG responses being observed with β-pinene, (+)-α-pinene and 1,8-cineole.Dose–response profiles showed positive dose-dependent responses for all three compounds. Ourresults suggest a broad sensitivity of P. myardi to common tree volatiles, particularly some hostrelatedcompounds and volatiles associated with wounded trees; the olfactory recognition of ratiosof these compounds could play a role in host selection by P. myardi.
