The experiments were organized in four Norway spruce stands (40-50 years old) outside its natural area, in the north-east of Romania, where <em>Ips duplicatus </em>(Sahlberg) populations had reached an epidemical level. Each experiment had five treatments randomly replicated in six blocks within each experimental plot. Four non-target bark beetle species were captured together with <em>Ips duplicatus</em>: <em>I.</em><em> typographus</em> (L.) (2611 beetles), <em>Pityogenes chalcographus </em>(L.) (184 beetles), <em>Hylastes cunicularius </em>Erichson (107 beetles) and <em>Dryocoetes autographus</em> (Ratzeburg) (24 beetles), representing 1.77%, 0.13%, 0.07% and 0.02% respectively of total captures. Beetles of <em>I.</em><em> typographus</em> were attracted by synthetic pheromone blend of <em>I.</em><em> duplicatus</em> and have intensified their response in the presence of (-)-alpha-pinene or a combination between (-)-alpha-pinene and (+)-limonene, but the other species have been captured in the traps accidentally. The positive response of <em>I.</em><em> typographus</em> to the present formulation of <em>I.</em><em> duplicatus</em> pheromone suggests the possibility to use the pheromone dispensers for both species in the same traps when mass-trapping is the main goal, but new studies should clarify the real effects of putting together pheromone dispensers of <em>I.</em><em> typographus</em> or <em>P. chalcographus</em> with those of <em>I.</em><em> duplicatus</em>.</p> ER -
