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...

Andersson, Martin N., Schlyter, Fredrik, Bohlmann, Jörg, Grosse-Wilde, Ewald, Li, Maria, Keeling, Christopher I., Hansson, Bill S., Bengtsson, Jonas M., Yuen, Macaire M.S., Hillbur, Ylva
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...

The mountain pine beetle, Dendroctonus ponderosae (Coleoptera: Curculionidae) is a major forest pest of pines in western North America. Beetles typically undergo a one-year life cycle with larval cold hardening in preparation for overwintering. Two-year life cycle beetles have been observed but...

Characterizing the physical and genetic structure of the lodgepole pine × jack pine hybrid zone: mosaic structure and differential introgression

Coltman, David W., James, Patrick M. A., Cullingham,Catherine I., Cooke, Janice E. K.
Understanding the physical and genetic structure of hybrid zones can illuminate factors affecting their formation and stability. In north-central Alberta, lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia) and jack pine (Pinus banksiana Lamb) form a complex and poorly defined hybrid...

Disentangling detoxification: Gene expression analysis of feeding mountain pine beetle illuminates molecular-level host chemical defense detoxification mechanisms
Download2013-01-01
Bohlmann, Jörg, Bonnett, Tiffany R., Pitt, Caitlin, Keeling, Christopher I., Yuen, Macaire M. S., Huber, Dezene P. W., Robert, Jeanne A.
The mountain pine beetle, Dendroctonus ponderosae, is a native species of bark beetle (Coleoptera: Curculionidae) that caused unprecedented damage to the pine forests of British Columbia and other parts of western North America and is currently expanding its range into the boreal forests of...

Chan, Simon K., Henderson, Hannah, Sperling, Felix A. H., Docking, Roderick T., Palmquist, Diana L., Nguyen, Anh, Zhao, Yongjun, Birol, Inanc, Pandoh, Pawan, Li, Maria, Taylor, Greg A., Liao, Nancy Y., Moore, Richard, Bohlmann, Joerg, Janes, Jasmine K., Jackman, Shaun D., Yuen, Macaire M. S., Huber, Dezene P. W., Jones, Steven J. M., Keeling, Christopher I.
Background The mountain pine beetle, Dendroctonus ponderosae Hopkins, is the most serious insect pest of western North American pine forests. A recent outbreak destroyed more than 15 million hectares of pine forests, with major environmental effects on forest health, and economic effects on the...

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...

Chiu, Christine C., Keeling, Christopher I., Henderson, Hannah M., Bohlmann, Joerg
The mountain pine beetle (MPB; Dendroctonus ponderosae) is a forest insect pest that attacks several different pine (Pinus) species in its native range of distribution in western North America. MPB are exposed for most of their life cycle to the chemical defenses of their hosts. These defenses...

Gene expression analysis of overwintering mountain pine beetle larvae suggests multiple systems involved in overwintering stress, cold hardiness, and preparation for spring development

Robert, Jeanne A., Bonnett, Tiffany R., Pitt, Caitlin, Spooner, Luke J., Fraser, Jordan D., Yuen, Macaire M. S., Keeling, Christopher I., Bohlmann, Jorg, Huber, Dezene P. W.
Cold-induced mortality has historically been a key aspect of mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae), population control, but little is known about the molecular basis for cold tolerance in this insect. We used RNA-seq analysis to monitor gene expression...

Genes, enzymes, and chemicals of terpenoid diversity in the constitutive and induced defence of conifers against insects and pathogens

Keeling, Christopher I., Bohlmann, Jörg
Insects select their hosts, but trees cannot select which herbivores will feed upon them. Thus, as long-lived stationary organisms, conifers must resist the onslaught of varying and multiple attackers over their lifetime. Arguably, the greatest threats to conifers are herbivorous insects and...
