Short-range horizontal disruption by verbenone in attraction of mountain pine beetle (Coleoptera: Scolytidae) to pheromone-baited funnel traps in stands of lodgepole pine
نویسنده
چکیده
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.

Nonhost angiosperm volatiles and verbenone were tested for their ability to disrupt the response of western pine beetle, Dendroctonus brevicomis LeConte (Coleoptera: Scolytidae), to attractant-baited multiple funnel traps. Verbenone significantly reduced attraction; however, no difference was observed between 4 and 50 mg/24-h release rates. Combinations of six bark volatiles (benzyl alcohol, be...
