cis-Verbenol: An aggregation pheromone for the mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Scolytidae)

Abstract

cis-Verbenol increased catches of mail mountain pine beetles, Dendroctonus ponderosae Hopkins, to multiple-funnel traps baited with myrcene and exo-brevicomin. Cis-Verbenol had no effect on the response of males to traps baited with myrcene, exo-brevicomin and trans-verbenol. In contrast, cis-verbenol increased catches of female D. ponderosae to semiochemical-baited traps irrespective of the absence or presence of trans-verbenol. Our results demonstrate that cis-verbenol is an aggregation pheromone for D. ponderisae and that the combination of cis- and trans-verbenol elicits sex-specific response.
