Pine engraver (Ips pini) Colonization of Logging Residues Created Using Alternative Slash Management Systems in Western Montana

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 ...

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

Importance of log size on host selection and reproductive success of Ips pini (Coleoptera: Scolytidae) in ponderosa pine slash of northern Arizona and western Montana.

Pine engraver, Ips pini (Say), often use thinning slash, and their populations are known to be influenced by the condition of this material. In our study, we evaluated the importance of three log diameters (5, 10, and 20 cm) and three lengths (60,120, and 240 cm) on various parameters of bark beetle host attack, development, and emergence. Evaluation of slash colonization in northern Arizona (n...

Composition of the bacterial community in the gut of the pine engraver, Ips pini (Say) (Coleoptera) colonizing red pine

The gut bacterial community of a bark beetle, the pine engraver Ips pini (Say), was characterized using culture-dependent and culture-independent methods. Bacteria from individual guts of larvae, pupae and adults were cultured and DNA was extracted from samples of pooled larval guts. Analysis of 16S rRNA gene sequences amplified directly from the gut community suggests that the gut bacterial co...

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

The effect of pheromones of Dendroc~onzl.~ poriderosae Hopkins on the attraction of Ipspini (Say) to its pheromone, ipsdienol, was investigated in stands of lodgepole pine. The mixture of cisand trans-verbenol significantly reduced catches of I pin; in traps baited with ipsdienol at three locations in British Columbia. exo-Brevicomi~~ had no effect on catches of 1 pini, irrespective of the enan...
