Influence of Semiochemical Cues on Mountain Pine Beetle Flight and Subsequent Effect of Flight on Host Colonisation Processes
DownloadFall 2019
The mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae), is an aggressive pine pest in western North America. This beetle undergoes cyclical population outbreaks, and in the most recent outbreak the beetle expanded its range to the north and east. During this range...

Modelling Mountain Pine Beetle Population Dynamics and Management: A Case Study from the Cypress Hills
DownloadFall 2019
Outbreaks of insects are one of the main sources of disturbance in North American pine forests. The huge economic and ecological consequences of these outbreaks emphasize the need for effective pest management. For example, the mountain pine beetle (Dendroctonus ponderosae, Hopkins 1902) has...

Pine Wars: A New Host Interactions between the mountain pine beetle (Dendroctonus ponderosae Hopkins) and its pine hosts in Canada's boreal forest
DownloadFall 2023
Mountain pine beetle (MPB) has undergone a climate change facilitated range expansion and has attacked and killed trees at higher latitudes and elevations than has ever been recorded. During outbreaks, MPB attack large healthy pine trees that will fight back against the colonizing beetles using...

Transcriptomic analyses of Pinus contorta responses to Grosmannia clavigera under contrasting levels of nitrogen availability
DownloadSpring 2021
In western Canada alone, the current mountain pine beetle (MPB) outbreak has devastated nearly 19 million hectares of pine forest, negatively impacting communities, industries and ecosystems. Reforestation efforts can benefit from a deeper understanding of the impact of nitrogen (N)-based...
