Genetic diversity of ITS sequences of Bursaphelenchus xylophilus

Genetics and Molecular Research, 2012
The sequence variation of internal transcribed spacer (ITS) regions of ribosomal DNA has been routinely used for species identification and species-level phylogeny of the pinewood nematode, Bursaphelenchus xylophilus. In this study, the intraspecies ITS genetic diversity of B. xylophilus was evaluated.

Optimal strategies for utilizing host plant distributions to slow the spread of plant pests

Journal of Applied Ecology, Volume 63, Issue 2, February 2026.
Containment of invasive species can be made markedly more cost‐effective by prioritizing landscape features that naturally impede spread. Targeting treatments around host‐plant gaps supports a clear operational rule: use mating disruption where densities are low to prevent establishment and concentrate pesticides where densities are high to suppress ...

The Factors Involved in Plant–Insect–Microbe Interactions Expanded: Genome Analysis and Description of Frigoribacterium adelgis sp. nov.

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Aerobic Actinobacteria belonging to the genus Frigoribacterium were isolated from adelgid Adelges (Aphrastasia) pectinatae collected from a Korean fir tree. Genomic analysis showed that these bacteria encode a range of factors that may be involved in the interactions between Frigoribacterium strains, adelgids and/or Korean fir trees.

Molecular biological characterization ofbursaphelenchus xylophilusandbursaphelenchus mucronatusin Korea

Forest Science and Technology, 2008
Pine wood nematode (PWN), Bursaphelenchus xylophilus, is a causal organism to induce pine wilt disease (PWD) in many varieties of pine trees. PWD was first introduced to Korea in 1988 but, the damage has been dramatically increased since 2000. Recently PWD is newly reported in Korean pine tree (Pinus koraien‐sis) and is considered one of the most ...

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 ...

Nematicidal bacteria associated to pinewood nematode produce extracellular proteases. [PDF]

PLoS ONE, 2013
Bacteria associated with the nematode Bursaphelenchus xylophilus, a pathogen of trees and the causal agent of pine wilt disease (PWD) may play a role in the disease.

Interaction Between Pinus Species and Foliar Fungal Pathogens: Similar Symptoms, Contrasting Physiology

Plant Pathology, Volume 75, Issue 1, January/February 2026.
Lecanosticta acicola and Dothistroma septosporum trigger similar symptoms; host responses diverge sharply: Pinus pinea mounts robust defences, P. pinaster remains vulnerable, and P. radiata sustains growth. These contrasting strategies highlight species‐specific resilience and provide key insights for sustainable forest protection.

Two decades of epidemiological surveillance of the pine wood nematode in France reveal its absence despite suitable conditions for its establishment

Annals of Forest Science, 2023
Key message This study takes stock of the first 20 years (2000–2019) of monitoring the pine wood nematode (PWN) in metropolitan France. While PWN was never found in the wild during this period, it was reported in some wood-based commodities entering or ...

A Detection Method of Pine Wilt Disease Based on Improved YOLOv11 With UAV Remote Sensing Images

Ecology and Evolution, Volume 15, Issue 12, December 2025.
The proposed YOLOv11‐OC model enhances detection performance in PWD‐infected trees in two main ways. On one hand, the omni‐dimensional dynamic convolution (ODConv) module improves the C3K2 by using a multi‐dimensional attention mechanism to adaptively adjust the convolution kernel weights, thereby enhancing the model's ability to extract features from ...

The effects of provenance, climate, and chemical defense on the resistance of Pinus pinaster Aiton to Bursaphelenchus xylophilus (Steiner and Buhrer)

Annals of Forest Science, 2023
Key message The resistance of Pinus pinaster Aiton to pinewood nematode Bursaphelenchus xylophilus (Steiner and Buhrer) varied among populations from the Iberian Peninsula, with survival rates for inoculated seedlings ranging from 5 to 100%.
