Selection of the sex-linked Inhibitor of Apoptosis in Mountain Pine Beetle (Dendroctonus ponderosae) driven by enhanced expression during early overwintering
Download2018
Horianopoulos, Linda C., Boone, Celia K., Samarasekera, Gayathri, Kandola, Gurkirat K., Murray, Brent W.
The mountain pine beetle (Dendroctonus ponderosae) is an insect native to western North America; however, its geographical range has recently expanded north in BC and east into Alberta. To understand the population structure in the areas of expansion, 16 gene‐linked microsatellites were screened...

Functions of mountain pine beetle cytochromes P450 CYP6DJ1, CYP6BW1 and CYP6BW3 in the oxidation of pine monoterpenes and diterpene resin acids

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...

The contribution of genetics and genomics to understanding the ecology of the mountain pine beetle system

Cullingham, Catherine I., Janes, Jasmine K., Hamelin, Richard C., James, Patrick M.A., Murray, Brent W., Sperling, Felix A.H.
Environmental change is altering forest insect dynamics worldwide. As these systems change, they pose significant ecological, social, and economic risk through, for example, the loss of valuable habitat, green space, and timber. Our understanding of such systems is often limited by the complexity...

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...

Global and comparative proteomic profiling of overwintering and developing mountain pine beetle, Dendroctonus ponderosae (Coleoptera: Curculionidae), larvae
Download2012
Keeling, Christopher I., Huber, Dezene P.W., Pitt, Caitlin, Fraser, Jordie D., Bohlmann, Jörg, Bonnett, Tiffany R., Robert, Jeanne A.
Background Mountain pine beetles, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae), are native to western North America, but have recently begun to expand their range across the Canadian Rocky Mountains. The requirement for larvae to withstand extremely cold winter temperatures and...

Wittische, Julian, Janes, Jasmine K., James, Patrick M. A.
The current mountain pine beetle (MPB; Dendroctonus ponderosae Hopkins, 1902) outbreak has reached more than 25 million hectares of forests in North America, affecting pine species throughout the region and substantially changing landscapes. However, landscape features that enhance or limit...

Repurposing population genetics data to discern genomic architecture: A case study of linkage cohort detection in mountain pine beetle (Dendroctonus ponderosae)
Download2019-01-01
Trevoy, Stephen A.L., Janes, Jasmine K., Muirhead, Kevin, Sperling, Felix A. H.
Genetic surveys of the population structure of species can be used as resources for exploring their genomic architecture. By adjusting filtering assumptions, genomewide single-nucleotide polymorphism (SNP) datasets can be reused to give new insights into the genetic basis of divergence and...

Seasonal shifts in accumulation of glycerol biosynthetic gene transcripts in mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae), larvae
Download2017
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...

Polygamy and an absence of fine-scale structure in Dendroctonus ponderosae (Hopk) (Coleoptera: Curcilionidae) confirmed using molecular markers
Download2016-01-01
Janes, Jasmine K., Roe, Amanda D., Rice, A. V., Gorrell, Jamieson C., Coltman, D. W., Langor, David W., Sperling, Felix A.
An understanding of mating systems and fine-scale spatial genetic structure is required to effectively manage forest pest species such as Dendroctonus ponderosae (mountain pine beetle). Here we used genome-wide single-nucleotide polymorphisms to assess the fine-scale genetic structure and mating...

Gene expression analysis of overwintering mountain pine beetle larvae suggests multiple systems involved in overwintering stress, cold hardiness, and preparation for spring development
Download2016
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...
