A new species of the genus Humboldtiana (Gastropoda, Stylommatophora, Xanthonychidae) from Sierra de Penjamo, Guanajuato, Mexico [PDF]

Biodiversity Data Journal
Mexican terrestrial malacofauna is highly diverse, but poorly studied. The genus Humboldtiana includes near to 60 species, most with insular distributions on single mountains from South Texas (USA) to entral Mexico.Humboldtiana dugesi sp. nov.

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

Scientific 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

Frontiers 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.

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.

Gut transcriptome of two bark beetle species stimulated with the same kairomones reveals molecular differences in detoxification pathways

Computational and Structural Biotechnology Journal, 2022
Dendroctonus bark beetles are the most destructive agents in coniferous forests. These beetles come into contact with the toxic compounds of their host's chemical defenses throughout their life cycle, some of which are also used by the insects as ...

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

Frontiers 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,

Acoustic Communication in Dendroctonus adjunctus Blandford (Curculionidae Scolytinae): Description of Calls and Sound Production Mechanism

Insects
The acoustic communication system (ACS) in bark beetles has been studied mainly in species of the genera Dendroctonus, Ips and Polygraphus. Specifically, ACS of the roundheaded pine beetle, Dendroctonus adjunctus, has been little studied.
