USING VERBENONE AND NON-HOST VOLATILES TO PREVENT PINE ENGRAVER BEETLE COLONIZATION OF PONDEROSA PINE SLASH, 2005-06

Use of Hericon Verbenone Flakes to Prevent Engraver Bark Beetle (Ips spp.)Colonization of Ponderosa Pine Slash

Efficacy of verbenone for protecting ponderosa pine stands from western pine beetle (Coleoptera: Curculionidae: Scolytinae) attack in California.

The western pine beetle, Dendroctonus brevicomis LeConte (Coleoptera: Curculionidae: Scolytinae), is a major cause of ponderosa pine, Pinus ponderosa Dougl. ex Laws., mortality in much of western North America. Currently, techniques for managing D. brevicomis infestations are limited. Verbenone (4,6,6-trimethylbicyclo [3.1.1] hept-3-en-2-one) is an antiaggregation pheromone of several Dendrocto...

Nonhost Angiosperm Volatiles and Verbenone Protect Individual Ponderosa Pines from Attack by Western Pine Beetle and Red Turpentine Beetle (Coleoptera: Curculionidae, Scolytinae)

combination with the host monoterpene myrcene is highly attractive to conspecifics (Bedard et al. 1969). Frontalin, produced by male WPB (Kinzer et al. 1969), enhances attraction. Poland et al. (1998) were the first to examine the disruptive effect of NAVs on WPB attraction, but their study was limited in scope to green leaf volatiles only and was conducted at the periphery of the beetle’s nati...

Nutritional and pathogenic fungi associated with the pine engraver beetle trigger comparable defenses in Scots pine.

Conifer bark beetles are often associated with fungal complexes whose components have different ecological roles. Some associated species are nutritionally obligate fungi, serving as nourishment to the larvae, whereas others are pathogenic blue-stain fungi known to be involved in the interaction with host defenses. In this study we characterized the local and systemic defense responses of Scots...

Pheromone interruption of pine engraver, Ips pini, by pheromones of mountain pine beetle, Dendroctonusponderosae (Coleoptera: Scolytidae)

The effect of pheromones of Hopkins on the at t ract ion of Ips pini (Say) to its pheromone, ipsdienol, was investigated in stands of lodgepole pine. The mixture of cisand trans-verbenol significantly reduced catches of 1. pini in t raps baited with ipsdienol at three locations in British Columbia. exo-Brevicomin had no effect on catches of f. pini, irrespective of the enantiomeric composition ...
