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...

Investigating Fire as a Silvicultural Tool for Regeneration of Mountain Pine Beetle-killed Serotinous Pine of Northern Alberta
DownloadSpring 2016
Serotinous pine forests in Western Canada are threatened by a record-breaking mountain pine beetle (Dendroctonus ponderosae; MPB) outbreak - the largest recorded in Western North America. Forest managers are concerned with whether these closed-cone MPB-killed forests will successfully regenerate....

Mandibles and labrum-epipharynx of tiger beetles: Basic structure and evolution (Coleoptera, Carabidae, Cicindelitae)
Download2011
Acorn, J. H., Ball, G. E., Shpeley, D.
Abstract: Using for comparison with, and as outgroups for, supertribe Cicindelitae, we describe and illustrate the mandibles and labrum-epipharynx of the basal geadephagans Trachypachus gibbsii LeConte, 1861 (family Trachypachidae), and family Carabidae: Pelophila rudis (LeConte, 1863)...

Saproxylic Beetles (Coleoptera) Associated With Aspen Deadwood in Broad-Leaved Boreal Mixedwood Stands
DownloadFall 2012
I assessed deadwood-associated (i.e., ‘saproxylic’) beetles (Coleoptera) along a decay gradient of trembling aspen in mature deciduous stands of the boreal mixedwood forest in NW Alberta. Various collection methods were employed to sample saproxylic beetle species. Assemblages differed between...

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...

The mountain pine beetle (Dendroctonus ponderosae Hopkins) (Coleoptera: Curculionidae) is a significant destructive force in the pine forests of western Canada and has the capacity to spread east into a novel host tree species, jack pine (Pinaceae). New populations have been documented in central...

The cytochrome P450 CYP6DE1 catalyzes the conversion of α-pinene into the mountain pine beetle aggregation pheromone trans-verbenol
Download2019-01-01
Chiu, Christine C., Keeling, Christopher I., Bohlmann, Joerg
The recent outbreak of the mountain pine beetle (Dendroctonus ponderosae; MPB) has afected over 20M hectares of pine forests in western North America. During the colonization of host trees, female MPB release the aggregation pheromone (−)-trans-verbenol. (−)-trans-Verbenol is thought to...
