“…Thus, this treatment remained effective in spite of the potential source of secondary attraction represented by the mass-attacked baited trees. These results expand on those of Wilson et al (1996), Borden et al (1998) Shore et al (1992), and Huber and Borden (2001), who showed that individual and paired baited trees can be protected. These studies also showed that attack on surrounding trees within 5 m of baited trees can also be reduced, probably because failure of D. ponderosae to mass-attack baited trees precluded the emission of beetle-produced pheromones that would have created a focussed attack.…”

We evaluated the antiaggregation pheromone verbenone at low and high doses alone and with a seven-component repellent blend of nonhost angiosperm bark volatiles (NHVs) for their ability to deter attack by the mountain pine beetle, Dendroctonus ponderosae Hopkins. Release devices containing antiaggregants were deployed at 16 points on a 10-m grid in 40 × 40-m plots near Williams Lake, B.C. in June 2001. In 10 control plots with no antiaggregants, single pheromone-baited trees, at the plot centre were all mass-attacked by the mountain pine beetle by early October, as were 26.6% of the 432 lodgepole pines within the boundaries of the plots. In contrast, in plots treated with a high dose of verbenone plus NHVs, two of the central, pheromone-baited trees escaped any attack whatsoever, four of 10 plots had no surrounding trees attacked and only 2.1% of the total of 523 surrounding trees were mass-attacked. Density of attacked and mass-attacked trees was highest within 5 m of the central baited tree in all treatments, indicating that those beetles that breached the antiaggregant grid were then drawn toward the baited tree. Operational efficacy should thus be improved in the absence of baited trees within a treated area. We conclude that high-dose verbenone plus NHV treatments could be implemented operationally as a minor component of an integrated pest management strategy for large infestations, particularly in a push-pull tactic in which beetles are pushed from one area by the antiaggregant treatment and drawn into another with attractive baits. However, the principal use would be in the short-term protection of small, high-value stands or stands of high ecological or social value.Key words: Coleoptera, Scolytidae, Dendroctonus ponderosae, chemical ecology, verbenone, pest management Nous avons évalué le phéromone antiagrégation verbenone seul à faibles et à fortes doses et avec un mélange répulsif de sept composants volatiles d'écorce d'angiosperme non-hôtes pour sa capacité à détourner les attaques du dendroctone du pin ponderosa, Dendroctonus ponderosae Hopkins. Les appareils permettant de répandre les antiagrégants ont été déployés sur 16 stations réparties selon un quadrillage de 10 m dans des parcelles de 40 × 40 m situées près de Williams Lake, C.-B., en juin 2001. Dans les 10 parcelles témoins sans antiagrégants, les arbres individuels traités comme appât aux phéromones, situés au centre des parcelles ont tous été attaqués massivement par le dendroctone dès le début d'octobre, ainsi que 26 % des 432 pins lodgepoles retrouvés dans les limites des parcelles. Par contre, dans le cas des parcelles traitées avec une forte dose de verbenone additionné du mélange répulsif, deux des arbres du centre traités comme appât aux phéromones ont échappé à toutes les attaques, quatre des 10 parcelles n'ont eu aucun arbre attaqué et seulement 2,1 % des 523 arbres situés à proximité ont été attaqués massivement. La densité des arbres attaqués et attaqués massivement était plus élevée en deçà de 5 m de l'arbre appât dans tous les...

“…Verbenone has antiaggregative properties for a number of scolytid beetles (Shore et al 1992;Borden 1997) and was detected in the captured volatiles of emerged and paired beetles of both sexes. It was previously identified in the hindguts of emergent and feeding femaies and in the volatiles of paired beetles (Pitman et ai.…”

“…Therefore, a tree at an advanced stage of attack would exude verbenone at levels that would signal a limited fresh resource. The production of frontalin in high amounts by males as soon as they joined females strongly suggests that high concentrations of frontalin in synergism with verbenone may mask or neutralise the effect of the aggregation pheromones exo-brevicomin and rrans-verbenol (Shore et al 1992) and terminate aggregation.…”

“…Thus, while verbenone has been shown in some trials to protect pines from bark beetle attack (Lindgren et al 1989;Shore et al 1992;Shea et al 1992;Lindgren & Borden 1993;Progar 2003) some failures (Gibson et al 1991;Shea et al 1992;Progar 2003) may not simply be due to photoisomerization of the compound to an inactive form as has been suggested (Kostyk et al 1993), but also due to a lack of creation of a realistic context for foraging insects. That is, synthetic verbenone alone, deployed without other beetle-derived or nonhost cues in appropriate quantities, may not always provide foraging beetles with the desired misinformation about the stand in which they are foraging.…”

Antennal responses of the western pine beetle, Dendroctonus brevicomis (Coleoptera: Curculionidae), to stem volatiles of its primary host, Pinus ponderosa, and nine sympatric nonhost angiosperms and conifers

Stem volatile extracts from ten trees that are sympatric with the western pine beetle, Dendroctonus brevicomis LeConte (Coleoptera: Curculionidae) were assayed by gas chromatographic-electroantennographic detection analysis (GC-EAD). The extracts were from the primary host, ponderosa pine, Pinus ponderosa Dougl. ex Laws. (Pinaceae); two nonhost angiosperms, California black oak, Quercus kelloggii Newb. (Fagaceae), and quaking aspen, Populus tremuloides Michx. (Salicaceae); and seven nonhost conifers, white fir, Abies concolor (Gord. & Glend.) Lindl. ex Hildebr. (Pinaceae), incense cedar, Calocedrus decurrens (Torr.) Florin (Cupressaceae), Sierra lodgepole pine, P. contorta murrayana Grev. & Balf. (Pinaceae), Jeffrey pine, P. jeffreyi Grev. & Balf. (Pinaceae), sugar pine, P. lambertiana Dougl. (Pinaceae), Douglas-fir, Pseudotsuga menziesii (Mirb.) Franco (Pinaceae), and mountain hemlock, Tsuga mertensiana (Bong.) Carr. (Pinaceae). Sixty-four compounds were identified from the ten trees, 42 of which elicited antennal responses in D. brevicomis, usually in both sexes. In addition, several synthetic compounds, including a number of the antennally-active compounds from the extracted trees and some bark beetle pheromone components, elicited antennal responses in a manner similar to that observed with the extracts. Of the antennally-active compounds known to be present in trees sympatric with D. brevicomis, only geraniol was unique to its host. Four antennally-active compounds were found in the host and in other conifers; five compounds were found only in nonhost conifers; eight compounds were found in either or both of the nonhost angiosperms; eight compounds were found in either or both of the angiosperms and in nonhost conifers, but not in the host; and 19 were found in both the host and in angiosperms and/or nonhost conifers. Several bark beetle pheromone components were found in the stem volatile extracts. Conophthorin was identified from both nonhost angiosperms; exo-brevicomin was identified in A. concolor; verbenone was identified from a number of nonhost conifers; and chalcogran was identified from P. tremuloides. The number of nonhost volatile chemicals that D. brevicomis encounters and is capable of detecting, and the diversity of sources from which they emanate, highlight the complexity of the olfactory environment in which D. brevicomis forages. This provides a basis for further work related to chemically-mediated aspects of foraging in this insect and perhaps other coniferophagous bark beetles, and highlights the need to consider foraging context in the design and implementation of semiochemical-based management tactics for tree protection.
