Cryptic Species Discrimination in Western Pine Beetle, Dendroctonus brevicomis LeConte (Curculionidae: Scolytinae), Based on Morphological Characters and Geometric Morphometrics

Insects, 2019
The western pine beetle (WPB), Dendroctonus brevicomis LeConte, is a major mortality agent of pines in North America. A total of 706 adults of WPB from 81 geographical sites were analyzed with traditional and geometric morphometric methods to evaluate ...

Abundance of Dendroctonus frontalis and D. mexicanus (Coleoptera: Scolytinae) along altitudinal transects in Mexico: Implications of climatic change for forest conservation.

PLoS ONE, 2023
Bark beetle infestations have historically been primary drivers of stand thinning in Mexican pine forests. However, bark beetle impacts have become increasingly extensive and intense, apparently associated with climate change.

Tree defence and bark beetles in a drying world: carbon partitioning, functioning and modelling. [PDF]

, 2020
Drought has promoted large-scale, insect-induced tree mortality in recent years, with severe consequences for ecosystem function, atmospheric processes, sustainable resources and global biogeochemical cycles.

Free rein: Are feral horses competing with native ungulates in British Columbia?

The Journal of Wildlife Management, Volume 90, Issue 3, April 2026.
We investigated little‐studied feral horses in west‐central British Columbia, Canada, as a potential competitor for native moose and mule deer. We did not find strong evidence that feral horses exclude moose or deer from habitat or resources at a large landscape scale or smaller spatiotemporal patch scale.

Use of Baited Pitfall Traps for Monitoring Pales Weevil, \u3ci\u3eHylobius Pales\u3c/i\u3e (Coleoptera: Curculionidae) [PDF]

, 2017
Pitfall traps baited with ethanol and turpentine serve as an effective tool for monitoring pales weevil (Hylobius pales) populations. Males and females are equally attracted to this bait. Neither component alone showed any attractiveness. The presence of

Potential of endophytic Beauveria bassiana against Coraebus (Coleoptera: Buprestidae) oak borers

Pest Management Science, Volume 82, Issue 4, Page 3523-3531, April 2026.
This study demonstrates that an endophytic, oak‐associated strain of Beauveria bassiana exhibits adaptations to Quercus plants and potential against Coraebus boring beetles, supported by distinctive biological traits. Abstract BACKGROUND Oak borers in the genus Coraebus, including the bark‐ and the wood‐boring beetles C. florentinus and C. undatus, are

Chromosome-level genome assembly and population genomic analyses provide insights into adaptive evolution of the red turpentine beetle, Dendroctonus valens

BMC Biology, 2022
Background Biological invasions are responsible for substantial environmental and economic losses. The red turpentine beetle (RTB), Dendroctonus valens LeConte, is an important invasive bark beetle from North America that has caused substantial tree ...

Ethanol-Enriched Substrate Facilitates Ambrosia Beetle Fungi, but Inhibits Their Pathogens and Fungal Symbionts of Bark Beetles

Frontiers in Microbiology, 2021
Bark beetles (sensu lato) colonize woody tissues like phloem or xylem and are associated with a broad range of micro-organisms. Specific fungi in the ascomycete orders Hypocreales, Microascales and Ophistomatales as well as the basidiomycete Russulales ...

The genome and stage‐specific transcriptomes of the carrot weevil, Listronotus oregonensis, reveal adaptive mechanisms for host specialisation and symbiotic interactions

Insect Molecular Biology, Volume 35, Issue 2, Page 126-138, April 2026.
Comprehensive genome and stage‐specific transcriptomes reveal 14,637 genes in Listronotus oregonensis, advancing genetic insights into a key agricultural pest. Compared with related species, L. oregonensis exhibits reduced chemoreceptor gene families but expanded detoxification gene clusters, reflecting its narrow host range and adaptability.
