Gondwanan Origin of Bark and Ambrosia Beetles and Their Rapid Worldwide Diversification During the Cretaceous

Journal of Biogeography, Volume 53, Issue 2, February 2026.
ABSTRACT Aim It is not trivial to estimate the relative contributions of dispersal, vicariance, and range contraction in explaining the present‐day distribution of ancient clades. In this study, we aim to infer the historical biogeography of bark and ambrosia beetles using a genus‐level time‐calibrated molecular phylogeny that encompasses 70% of all ...

Commodity risk assessment of Hamamelis mollis plants from the UK

EFSA Journal, Volume 24, Issue 2, February 2026.
Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers plant health risks posed by rooted plants in pots of Hamamelis mollis ...

Infection Models for Pine Wilt Disease on the Basis of Vector Behaviors

Population Ecology, Volume 68, Issue 1, January 2026.
Infection models for pine wilt disease without vector density were built to estimate the transmission coefficient of the pathogenic nematode. The models successfully simulated the annual change in the density of infected trees for four pine stands. ABSTRACT Pine wilt disease is caused by the pinewood nematode (Bursaphelenchus xylophilus Steiner et ...

Pest categorisation of non‐EU Scolytinae on non‐coniferous hosts

EFSA Journal
Abstract The EFSA Panel on Plant Health performed a group pest categorisation for the EU territory of non‐EU Scolytinae (Coleoptera: Curculionidae) on non‐coniferous hosts, which total 6495 known species. Most species attack apparently healthy, weakened or dead trees, either feeding on the phloem (‘bark beetles’ subgroup) or on fungi inoculated into ...

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

Ecological Applications, Volume 36, Issue 1, January 2026.
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.

Effects of Norway Spruce (Picea abies) Stump Debarking on Insect Colonization in the Polish Sudety Mountains

Mountain Research and Development, 2016
This study aimed to determine whether debarking of Norway spruce stumps influences the intensity of their colonization by insects. The observed stumps of Picea abies (L.) H Karst were located in the eastern Sudety Mountains at elevations between 600 and ...

A taxonomic monograph of Nearctic Scolytus Geoffroy (Coleoptera, Curculionidae, Scolytinae)

ZooKeys, 2014
The Nearctic bark beetle genus Scolytus Geoffroy was revised based in part on a molecular and morphological phylogeny. Monophyly of the native species was tested using mitochondrial (COI) and nuclear (28S, CAD, ArgK) genes and 43 morphological characters in parsimony and Bayesian phylogenetic analyses.

Repellent Effects of Host Essential Oils and Limited Effects of Host Length on Tree‐Killing Bark Beetle Attacks

Entomologia Experimentalis et Applicata, Volume 174, Issue 1, Page 37-44, January 2026.
This study demonstrated that the host essential oil significantly reduced Polygraphus proximus Blandford (Coleoptera: Scolytinae) attack density, but the density did not differ significantly among logs of various lengths of Abies sachalinensis. Our study suggests that host essential oils can perform as repellents against conifer‐infesting bark beetles.
