1 A four‐arm olfactometer was used to test the effect of permethrin ‘Gori 920 ® ’ and the wax treatment ‘CereNat ® E30’ on the response of mature adult Hylobius abietis to olfactory stimuli from seedlings of Pinus sylvestris and Picea abies . 2 Also investigated in the olfactometer was the effect of Rotstop ® , a biofungicide for the control of Fomes root and butt rot, Heterobasidion annosum , on the responses of mature adult female H. abietis to stump material of both P. sylvestris and P. abies . 3 Hylobius abietis was significantly more attracted to untreated P. sylvestris seedlings compared to those treated with CereNat ® E30 or permethrin Gori 920 ® . No differences in response to P. abies seedlings were found. 4 With Rotstop ® , no changes in the attractiveness of P. sylvestris stump material were found, but that of P. abies was significantly increased compared to untreated material.
