Aftermath of mountain pine beetle outbreak in British Columbia: Stand dynamics, management response and ecosystem resilienceDownload
The mountain pine beetle (Dendroctonus ponderosae Hopkins) (MPB) has infested and killed millions of hectares of lodgepole pine (Pinus contorta var. latifolia Engelm) forests in British Columbia, Canada, over the past decade. It is now spreading out of its native range into the Canadian boreal...
The effect of water limitation on tree defense and host suitability of lodgepole and jack pine for Dendroctonus ponderosaeDownload
The mountain pine beetle (MPB; Dendroctonus ponderosae) has recently expanded its range from lodgepole pine forest into the lodgepole × jack pine hybrid zone in central Alberta, within which it has attacked pure jack pine. This study tested the effects of water limitation on tree defense response...
Variations in jack pine (Pinus banksiana) monoterpene composition and subsequent effects on pheromone production by mountain pine beetle (Dendroctonus ponderosae)Download
The secondary compounds of pines (Pinus) can strongly affect the physiology, ecology and behaviour of bark beetles (Coleoptera: Curculionidae, Scolytinae) that feed on host sub-cortical tissues. Jack pine (Pinus banksiana) has a wide distribution range in North America and thus variations in its...
Playing with fire: Dendroctonus ponderosae (mountain pine beetles) in post-burn lodgepole pine forestsDownload
Dendroctonus ponderosae, an aggressive tree-killing bark beetle, is one of the most significant insects in the coniferous forests of western North America. Although D. ponderosae is restricted to weakened host trees at low-density populations, fire can suddenly increase the number of suitable,...
Gene discovery for enzymes involved in limonene modification or utilization by the mountain pine beetle-associated pathogen Grosmannia clavigeraDownload
To successfully colonize and eventually kill pine trees, Grosmannia clavigera (Gs cryptic species), the main fungal pathogen associated with the mountain pine beetle (Dendroctonus ponderosae), has developed multiple mechanisms to overcome host tree chemical defenses, of which terpenoids are a...
Factors influencing flight capacity of the mountain pine beetle (Coleoptera: Curculionidae: Scolytinae)Download
The mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae) is the most damaging pest of mature pine (Pinaceae) in western North America. Although mountain pine beetles have an obligate dispersal phase during which adults must locate a new host for brood...
Influence of water deficit on the molecular responses of Pinus contorta × Pinus banksiana mature trees to infection by the mountain pine beetle fungal associate, Grosmannia clavigeraDownload
Conifers exhibit a number of constitutive and induced mechanisms to defend against attack by pests and pathogens such as mountain pine beetle (Dendroctonus ponderosae Hopkins) and their fungal associates. Ecological studies have demonstrated that stressed trees are more susceptible to attack by...
Antennal transcriptome analysis of chemosensory gene families in tree killing bark beetles, Ips typographus andDendroctonus ponderosae (Coleoptera: Curculionidae: Scolytinae)Download
Background The European spruce bark beetle, Ips typographus, and the North American mountain pine beetle, Dendroctonus ponderosae (Coleoptera: Curculionidae: Scolytinae), are severe pests of coniferous forests. Both bark beetle species utilize aggregation pheromones to coordinate mass-attacks on...
Irruptive forest insect pests cause considerable ecological and economic damage, and their outbreaks have been increasing in frequency and severity. We use a phylogeographic approach to understand the location and progression of an outbreak by the MPB (Dendroctonus ponderosae Hopkins), an...
Abstract: There are concerns that large-scale stand mortality due to mountain pine beetle (MPB) could greatly reduce natural regeneration of serotinous Rocky Mountain (RM) lodgepole pine (Pinus contorta var. latifolia) because the closed cones are held in place without the fire cue for cone...
