Temperature changes reveal different transcriptional responses in the larvae of the bark beetle Dendroctonus rhizophagus during the cold season [PDF]

open access: yesScientific Reports
Bark beetle, Dendroctonus rhizophagus, colonises and kills healthy sapling pine trees in the Sierra Madre Occidental, Mexico. In the autumn, its fifth-instar larvae migrate to the host’s roots (hibernaculum) to overwinter; however, little is known about ...

Evolution and functional role prediction of the CYP6DE and CYP6DJ subfamilies in Dendroctonus (Curculionidae: Scolytinae) bark beetles

open access: yesFrontiers in Molecular Biosciences, 2023
Dendroctonus-bark beetles are natural components and key ecological agents of coniferous forests. They spend most of their lives under the bark, where they are exposed to highly toxic terpenes present in the oleoresin.

Bacteriome from Pinus arizonica and P. durangensis: Diversity, Comparison of Assemblages, and Overlapping Degree with the Gut Bacterial Community of a Bark Beetle That Kills Pines

open access: yesFrontiers in Microbiology, 2018
Symbioses between plants and microorganims have been fundamental in the evolution of both groups. The endophytic bacteria associated with conifers have been poorly studied in terms of diversity, ecology, and function. Coniferous trees of the genera Larix,

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

open access: yesFrontiers 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.
