“…2). This suggests that general increases in the release rates of verbenone are not always associated with decreases in D. brevicomis trap catches as has been suggested by other authors (Bedard et al 1980a, Tilden andBedard 1988). Differences are likely inßu-enced by the stereochemistries and release rates of both the attractant (positive control) and verbenone used in these behavioral assays.…”

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, benzaldehyde, trans-conophthorin, guaiacol, nonanal, and salicylaldehyde), three green leaf volatiles [(E)-2-hexenal, (E)-2-hexen-1-ol, and (Z)-2-hexen-1-ol], and the nine compounds combined did not significantly reduce D. brevicomis response to attractant-baited traps. However, a significant effect was observed when the bark and green leaf volatiles were combined with verbenone. The nine nonhost angiosperm volatiles (NAVs) significantly augmented the effect of both release rates of verbenone, reducing trap catches to levels significantly below that of either release rate of verbenone alone. trans-Conophthorin, a compound reported to have behavioral activity in a number of other scolytids, was not critical to the efficacy of our NAV blend. Our results suggest that the addition of nonhost angiosperm volatiles to verbenone could be important for developing successful semiochemical-based management techniques for D. brevicomis.

“…In 1970, verbenone was demonstrated to elicit a negative response on tethered, ßying D. brevicomis females (Hughes and Pitman 1970). Bedard et al (1980a) showed that verbenone reduced the number of D. brevicomis trapped at a baited source. Trap catches were further reduced by higher release rates of verbenone (Bedard et al 1980a, b;Tilden and Bedard 1988).…”

“…Verbenone acts as an inhibitor for various species of bark beetles (Payne et al 1978, Bedard et al 1980, Devlin and Borden 1994, McPheron et al 1997, Rappaport et al 2001. The lack of any interruptive effect by verbenone on the attraction of I. pini and I. grandicollis is particularly surprising.…”

Sirex noctilio F. (Hymenoptera: Siricidae) is an invasive woodwasp, currently established in northeastern North America. In other regions of the world, stressed trap trees are used to monitor populations of S. noctilio and to provide inoculation points for the biological control nematode Deladenus siricidicola Bedding. However, the operational use of trap trees for S. noctilio in North America may be compromised by the large community of native organisms that inhabit stressed and dying pine trees. Common bark beetles such as Ips pini (Say) and Ips grandicollis (Eichhoff) (Coleoptera: Scolytidae) could potentially compete with S. noctilio and associates for resources on trap trees, possibly reducing the efficacy of trap trees as habitats for the woodwasp. In an attempt to develop a technology to mitigate this potential issue, three common semiochemical interruptants--conophthorin, green leaf volatile mix, and verbenone--were tested for effectiveness in reducing arrivals of I. pini and I. grandicollis on trap trees treated with herbicides in northeastern United States. In addition, the effects of these compounds were determined independently with pheromone-baited multiple-funnel traps. None of the interruptants reduced numbers of I. pini or I. grandicollis either arriving on trap trees or caught in pheromone-baited traps. However, verbenone increased catches of I. grandicollis in traps baited with its pheromone, ipsenol. The mix of green leaf volatiles reduced catches of a native ambrosia beetle, Gnathotrichus materiarius (Fitch), whereas verbenone reduced trap catches of an exotic ambrosia beetle, Xylosandrus germanus (Blandford). Catches of X. germanus in traps adjacent to trap trees were enhanced with conophthorin.

“…In the mountain pine beetle, D. ponderosae, trans-verbenol is the major component of the aggregation pheromone released by solitary females attacking a host and acts synergistically rather than redundantly with host odours Skillen et al, 1997). In the western pine beetle, D. brevicomis, it is released by arriving females but appears to act as a multifunctional pheromone component, enhancing attraction at a low release rate but decreasing it at a high rate (Bedard et al, 1980a;Byers et al, 1984).…”
