Abstract
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 formation of a spot infestation in stands of lodgepole pine.
