Tree defenses, host choice, and reproductive success of a native bark beetle under novel outbreak conditions. [PDF]

Ecol Appl
Abstract Bark beetles of the genus Dendroctonus are some of the most important disturbance agents in North American forests, having colonized conifers for millions of years. The selection pressure posed by tree‐killing bark beetles pushed trees to develop an arsenal of defensive strategies to which beetles have adapted in their turn.

From beginning to end: the synecology of tree-killing bark beetles, fungi, and trees. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Over a century of research has revealed an amazing complexity of behaviours and physiological adaptations that allow tiny bark beetles to overcome large trees, sometimes resulting in outbreaks that kill millions of trees. Turning a tree into a home and successfully raising offspring involves constant interactions among the beetles, the tree ...

The spermatheca in the genus Dendroctonus (Curculionidae: Scolytinae): morphology, nomenclature, potential characters for taxonomic use and phylogenetic signal

Revista Mexicana de Biodiversidad, 2022
In most members of the genus Dendroctonus, the usefulness of the spermatheca for taxonomic purposes has not been evaluated in depth; therefore, the aim of this study is to describe and compare the elements that integrate the female reproductive ...

Where Dinner Roams: The Role of Feral Horses as a Resource Subsidy for Wolves and Cougars in West-Central British Columbia. [PDF]

Ecol Evol
In west‐central British Columbia, large populations of feral horses overlap with native species like caribou and predators such as wolves and cougars, potentially disrupting predator–prey dynamics. Between 2019 and 2025, researchers documented multiple instances of wolf and cougar predation on feral horses—the first such confirmed cases in the region ...

Metabarcoding of mycetangia from the Dendroctonus frontalis species complex (Curculionidae: Scolytinae) reveals diverse and functionally redundant fungal assemblages

Frontiers in Microbiology, 2022
Dendroctonus-bark beetles are associated with microbes that can detoxify terpenes, degrade complex molecules, supplement and recycle nutrients, fix nitrogen, produce semiochemicals, and regulate ecological interactions between microbes.

Disruptant Effects of 4-Allylanisole and Verbenone on \u3ci\u3eTomicus Piniperda\u3c/i\u3e (Coleoptera: Scolytidae) Response to Baited Traps and Logs [PDF]

, 2018
We assessed the inhibitory effects of the host compound 4-allylanisole (release rates = 1 and 2 mg/d in 1994, and 1 and 10 mg/d in 2001) on the response of the pine shoot beetle, Tomicus piniperda (L.), adults to funnel traps baited with the attractant ...

Coordinated RNA-Seq and peptidomics identify neuropeptides and G-protein coupled receptors (GPCRs) in the large pine weevil Hylobius abietis, a major forestry pest [PDF]

, 2018
Hylobius abietis (Linnaeus), or large pine weevil (Coleoptera, Curculionidae), is a pest of European coniferous forests. In order to gain understanding of the functional physiology of this species, we have assembled a de novo transcriptome of H. abietis,
