AB Wood-boring insects, such as Cerambyx welensii Küster, are involved in oak decline inMediterranean areas. To advance our understanding of the olfactory perception of C. welensii, werecorded electroantennographic (EAG) responses from male and female antennae to 32 tree volatileorganic compounds typical of emissions from its main Quercus L. hosts, and also analysed thedose-dependent response. Cerambyx welensii antennae responded to 24 chemicals. Eight odorantselicited the highest EAG responses (normalized values of over 98%): 1,8-cineole, limonene-type blend,β-pinene, pinene-type blend, sabinene, α-pinene, turpentine and (E)-2-hexenal. Cerambyx welensiiexhibits a broad sensitivity to common tree volatiles. The high EAG responses to both limoneneand pinene-type blends suggest the detection of specific blends of the main foliar monoterpenesemitted by Q. suber L. and Q. ilex L. (limonene, α- and β-pinene, sabinene and myrcene), which couldinfluence the intraspecific host choice by C. welensii, and in particular, females may be able to detectoak trees with a limonene-type chemotype. In addition, C. welensii showed high antennal activity tosome odorants that characterize emissions from non-host tree species (1,8-cineole, β-pinene, α-pinene,turpentine, δ3-carene and camphene). The results obtained may be applicable to optimize monitoringand mass-trapping programmes in an integrated pest management context
