Disruption of Dendroctonus frontalis (Col., Scolytidae) infestations with an inhibitor

Use of the Dendroctonus frontalis inhibitor pheromone verbenone, as a treatment on trees within infestations, is effective in suppressing or halting infestation growth. It is hypothesized that the inhibitor disrupts the orientation of flying adult D. frontalis to host trees and, as a result, sufficient attacking adults are not available at any given time on a tree to successfully over take it. Seasonal changes in abundance, longevity, and dispersal of beetle populations may impact the effectiveness of the inhibitor-based treatment.
