Tree-killing bark beetles are major disturbance agents affecting coniferous forest ecosystems. The role of environmental conditions on driving beetle outbreaks is becoming increasingly important as global climatic change alters environmental factors, such as drought stress, that, in turn, govern...

Comparative phylogeography, genetic differentiation, and contrasting reproductive modes in three fungal symbionts of a multipartite bark beetle symbiosis
Download2011-02-01
Roe, Amanda, Rice, Adrianne, Coltman, David, Cooke, Janice, Sperling, Felix
Grosmannia clavigera is a fungal pathogen of pine forests in western North America and a symbiotic associate of two sister bark beetles: Dendroctonus ponderosae and D. jeffreyi. This fungus and its beetle associate D. ponderosae are expanding in large epidemics in western North America. Using the...

When working with contemporary spatial ecological datasets, statistical modellers are often confronted by two major challenges: (I) the need for covariance models with the flexibility to accomodate directional patterns of anisotropy; and (II) the computational effort demanded by high-dimensional...

Consequences of mountain pine beetle outbreak on forest ecosystem services in western Canada
Download2016-01-01
Dhar, Amalesh, Parrott, Lael, Heckbert, Scott
After affecting millions of hectares of pine forests in western Canada , the mountain pine beetle (MPB; Dendroctonous ponderosae Hopkins) is spreading out of its native range and into Canada's boreal forest . Impacts of outbreaks can be environmental, economic, and social, and an ecosystem...

Worldwide, forest pathogens are a major cause of forest disturbances and can impact economic revenues and endanger host species and their ecosystems. Genomics represents one of the most promising avenues to better understand and prevent forest disease epidemics. Pathogen genome characterization...

Keeling, Christopher I., Blomquist, Gary J., Tittiger, Claus
In several pine bark beetle species, phloem feeding induces aggregation pheromone production to coordinate a mass attack on the host tree. Male pine engraver beetles, Ips pini (Say) (Coleoptera: Scolytidae), produce the monoterpenoid pheromone component ipsdienol de novo via the mevalonate...

Effect of Environmental Conditions on Flight Capacity in Mountain Pine Beetle (Coleoptera: Curculionidae: Scolytinae)
Download2020-10-01
Wijeranthna, Asha, Evenden, Maya
Mountain pine beetle (Dendroctonus ponderosae Coleoptera: Curculionidae: Scolytinae) is a major pest of pine (Pinaceae) in western North America. Mountain pine beetle has an obligatory dispersal phase during which beetles fly in search of new hosts to colonize. Climatic factors may influence...

Effect of semiochemical exposure on flight propensity and flight capacity of Dendroctonus ponderosae in laboratory bioassays
Download2021-04-01
Jones, Kelsey L., Evenden, Maya L.
During flight, insect herbivores respond to volatile organic compounds (VOCs) released by host and non-host plants or conspecifics. Dendroctonus ponderosae uses chemical cues including host and non-host VOCs, as well as aggregation pheromones to navigate through the environment and find a...

Wijerathna, Asha, Evenden, Maya
The mountain pine beetle, Dendroctonus ponderosae Hopkins is a major native pest of pine (Pinus Linnaeus (Pinaceae)) in western North America. Host colonization by mountain pine beetle is associated with an obligatory dispersal phase, during which beetles fly in search of a suitable host....

Evolving symbioses between insects and fungi that kill trees in Canada: New threats associated with invasive organisms
Download2016-01-01
Symbiotic relationships between insects and fungi are known to cause tree mortality either through direct damage by larval feeding that can be facilitated by symbiotic fungi, or through insects vectoring pathogens directly to healthy trees. Within their native ranges, the impacts of...
