All NHVs tested elicited dose-dependent antennal responses by D. valens. In Y-tube olfactometer trials D. valens were repelled by NHVs tested. When NHVs were added to a kairomone blend responses of D. valens were significantly inhibited. Further field trapping experiments showed that attraction of D. valens to kairomone baited traps was reduced by all individual NHVs with reductions ranging from to 70 . 1-Octen-3-ol Z -3-hexen-1-ol and E -2-hexen-1-ol were the three most effective NHVs significantly reducing D. valens to kairomone-baited traps by and respectively. In the development and implementation of a semiochemical-based management programme for D. valens NHVs may have considerable potential for disrupting the beetle s ability to locate suitable hosts. non-host volatiles red turpentine beetle electroantennograms olfactory response field trapping Résumé - Réponses électrophysiologiques et comportementales de Dendroctonus valens à des composes volatils non-hôtes.
