Emergence of Buprestidae, Cerambycidae, and Scolytinae (Coleoptera) from Mountain Pine Beetle-Killed and Fire-Killed Ponderosa Pines in the Black Hills, South Dakota, USA

Abstract

ABSTRACT Wood borers (Coleoptera: Cerambycidae and Buprestidae) and bark beetles (Coleoptera: Curculionidae) infest ponderosa pines, Pinus ponderosa P. Lawson and C. Lawson, killed by mountain pine beetle (MPB), Dendroctonus ponderosae Hopkins, and fire. No data is available comparing wood borer and bark beetle densities or species guilds associated with MPB-killed or fire-killed trees from the Black Hills of South Dakota, USA. We compared species assemblages of wood borers (Cerambycidae and Buprestidae) and bark beetles (Dendroctonus spp. and Ips spp. (Coleoptera: Curculionidae)) emerging from bolts collected from trees that had been killed by MPB or fire one or two years prior to harvesting. Significantly more wood borers emerged from bolts of fire-killed trees than from bolts of MPB-killed trees. Wood borer density in fire-killed trees was 13.8 per m2, compared to 4.4 per m2 in MPB-killed trees. Six wood borer species, Acanthocinus obliquus (LeConte), Buprestis consularis Gory, Chrysobothris sp., Melan...
