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

چکیده
c-is-Verbenol increased catches of male mountain pine beetles, Dendroctonus ponderosae Hopkins, to multiple-funnel traps baited with myrcene and em-brevicomin. cis-Verbenol had no effect on the response of males to traps baited with myrcene, exo-brevicomin and tl-ans-verbenol. In contrast, cis-verbenoi inct-eased 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. ponderosae and that the combination of cisand truns-verbenol elicits sex-specific responses. Additional keywords: trans-verbenot, myrcene, e-xo-brevicomin, sex-specificity.

Verbenone interrupted the attraction of mountain pine beetle, Dendroctonus ponderosae Hopkins, to baited multiple-funnel traps at a distance of <4 m. Catches of beetles in traps placed 24 m from traps with verbenone were not significantly lower than catches in control traps. These results are consistent with the short-range phenomenon of “switching” exhibited by mountain pine beetle in the form...
