Adaptive and neutral markers both show continent-wide population structure of mountain pine beetle (Dendroctonus ponderosae)
Download2016-01-01
Sperling, Felix A. H., Murray, Brent W., Batista, Philip D., Janes, Jasmine K., Boone, Celia K.
Assessments of population genetic structure and demographic history have traditionally been based on neutral markers while explicitly excluding adaptive markers. In this study, we compared the utility of putatively adaptive and neutral single-nucleotide polymorphisms (SNPs) for inferring mountain...

Comparison of lodgepole and jack pine constitutive and induced resin chemistry: implications for range expansion by the mountain pine beetle, Dendroctonus ponderosae, (Coleoptera: Curculionidae)

Clark, Erin L., Carroll, Allan L., Huber, Dezene P.W., Lindgren, B. Staffan, Pitt, Caitlin
The mountain pine beetle, Dendroctonus ponderosae, is a significant pest of lodgepole pine in British Columbia (BC), where it has recently reached an unprecedented outbreak level. Although it is native to western North America, the beetle can now be viewed as a native invasive because for the...

Client sexual advances may be a common occurrence in therapy, yet there is little information available with strategies for managing them. In hope of initiating a dialogue, five female therapists’ experiences were examined for possible insights. Informal semi-structured interviews provided data...

Keeling, Christopher I., Bearfield, Jeremy C., Blomquist, Gary J., Schlauch, Karen, Tittiger, Claus, Young, Sharon, Aw, Tidiane
Background The mountain pine beetle (Dendroctonus ponderosae) is a significant coniferous forest pest in western North America. It relies on aggregation pheromones to colonize hosts. Its three major pheromone components, trans-verbenol, exo-brevicomin, and frontalin, are thought to arise via...

Interactions of pea leaf weevil (Coleoptera: Curculionidae) with its primary and secondary host plants in Alberta
DownloadFall 2021
The pea leaf weevil, Sitona lineatus Linnaeus (Coleoptera: Curculionidae), is an invasive, oligophagous herbivore that feeds on a variety of legume (Fabales: Fabaceae) plants. Field peas (Pisum sativum) and faba bean (Vicia faba) are the primary host plants of the pea leaf weevil. Adult weevils...

Optimization of semiochemical monitoring for pea leaf weevil, Sitona lineatus (Coleoptera: Curculionidae), in the Prairie Provinces
DownloadFall 2017
The pea leaf weevil, Sitona lineatus Linnaeus (Coleoptera: Curculionidae) is an invasive pest of increasing concern to pulse producers in the Canadian Prairie Provinces. Pea leaf weevil larvae cause damage to field pea (Pisum sativum) and faba bean (Vicia faba) crops by feeding on root nodules...

Phoretic mite associates of mountain pine beetle at the leading edge of an infestation in northwestern Alberta, Canada
Download2011
Proctor, H. C., Evenden, M. L., Mori, B. A., Walter, D. E.
Abstract: We identified species of mites phoretically associated with mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae), collected from bolts of lodgepole pine, Pinus contorta Douglas ex Louden (Pinaceae), and pheromone-baited traps in northwestern...

Seasonal shifts in accumulation of glycerol biosynthetic gene transcripts in mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae), larvae
Download2017
Fraser, Jordie D., Bonnett, Tiffany R., Keeling, Christopher I., Huber, Dezene P.W.
Winter mortality is a major factor regulating population size of the mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae). Glycerol is the major cryoprotectant in this freeze intolerant insect. We report findings from a gene expression study on an overwintering...

Testing for trade-offs between flight and reproduction in the mountain pine beetle (Coleoptera: Curculionidae) on two pine hosts
Download2019-01-01
Wijerathna, Asha, Whitehouse, Caroline, Proctor, Heather, Evenden, Maya
Mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae) adults fly to disperse before host colonization. The effect of flight on reproduction was tested by comparing the number and quality of offspring from beetles flown on flight mills to that of unflown...

Trees Wanted - dead or alive! Host selection and population dynamics in tree-killing bark beetles
Download2011
Erbilgin, N., Gregoire, J. C., Gilbert, M., Kausrud, K. L., Skarpaas, O., Stenseth, N. C., Okland, B.
Abstract: Bark beetles (Coleoptera: Curculionidae, Scolytinae) feed and breed in dead or severely weakened host trees. When their population densities are high, some species aggregate on healthy host trees so that their defences may be exhausted and the inner bark successfully colonized, killing...
