However, few studies have explored their effects on subsequent amounts of bark beetle caused tree mortality in interior ponderosa pine, Pinus ponderosa Dougl. ex P. & C. Laws. var. ponderosa. In this study, we examined bark beetle responses to creation of midseral (low diversity) and late-seral stages (high diversity) and the application of prescribed fire on 12 experimental units ranging in size from 76 to 136 ha. A total of 9500 (5.0% of all trees) Pinus and Abies trees died 2 years after treatment of which 28.8% (2733 trees) was attributed to bark beetle colonization. No significant difference in the mean percentage of trees colonized by bark beetles was found between low diversity and high diversity. The application of prescribed fire resulted in significant increases in bark beetle caused tree mortality (all species) and for western pine beetle, Dendroctonus brevicomis LeConte, mountain pine beetle, Dendroctonus ponderosae Hopkins, Ips spp., and fir engraver, Scolytus ventralis LeConte, individually. Approximately 85.6% (2339 trees) of all bark beetle caused tree mortality occurred on burned split plots. The implications of these and other results to sustainable forest management are discussed.10aDendroctonus brevicornis10aDendroctonus ponderosae10aIps10aScolytus ventralis1 aFettig, Christopher, J.1 aBorys, Robert, R.1 aMcKelvey, Stephen, R.1 aDabney, Christopher, P.  uhttps://weevil.myspecies.info/blacks-mountain-experimental-forest-bark-beetle-responses-differences-forest-structure-and-applicati02621nas a2200205   4500008004500000020002500045245011100070210006900181260000800250300001400258490000800272520189700280653001702177653000802194653002702202100002002229700002302249700002502272856011802297       2011                        Engldsh    a0013-8746; 1938-290100aEffects of Various Semiochemicals on the Responses of Rhyzopertha dominica to Pheromone Traps in the Field0 aEffects of Various Semiochemicals on the Responses of Rhyzoperth  cNov  a1297-13020 v1043 aFeeding male Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae) produces two pheromones Dominicalure-1 (DL-1) and Dominicalure-2 (DL-2), which attracts adults of both sexes. In field experiments conducted in Oklahoma, R. dominica captures in multiple funnel traps deployed with its pheromones, ethanol, or both, green-leaf volatiles (GLV), plant essential oils, or synthetic pheromones for Ips spp., Dendroctonus spp., or Scolytus multistriatus (Marsham) (Coleoptera: Scolytidae) were examined. The bark beetle lures were evaluated at the release rate recommended for the respective insects. The number of insects trapped increased when R. dominica lure was combined with ethanol, whereas beetle captures neither were enhanced nor inhibited when the lure was combined with GLV, 3-methylcyclohex-2-en-l-one (MCH), or plant essential oil mixtures turpentine, from Pinus spp., and cedar wood oil, from Juniperus spp. (Coniferales: Pinaceae and Cupressaceae). Similarly, the numbers of captured R. dominica did not significantly differ when R. dominica lures were supplemented with ipsdienol, ipsenol, cis-verbenol, or pityol. Conversely, the combination of R. dominica lures with exo-brevicomin, frontalin, and commercial lure for S. multistriatus, containing the bicyclic ketal multistriatin, resulted in significantly fewer captures of R. dominica. The presence of live males of the closely related species Prostephanus truncatus (Horn) decreased the number of captured R. dominica by >70% compared with captures in traps baited with R. dominica's natural pheromone alone. Results support the hypothesis that grain-infesting R. dominica evolved from forest-inhabiting ancestors and retained behavioral traits for semiochemical interactions with other wood-boring beetle species. Such interspecific interactions have potential for exploitation in pest management programs against R. dominica.10aDendroctonus10aIps10aScolytus multistriatus1 aEdde, Peter, A.1 aToews, Michael, D.1 aPhillips, Thomas, W.  uhttps://weevil.myspecies.info/effects-various-semiochemicals-responses-rhyzopertha-dominica-pheromone-traps-field
