Low abundance of phytophagous nematodes under invasive exotic Pinus elliottii – enemy release and plant–soil feedbacks

New Phytologist, Volume 249, Issue 6, Page 3060-3071, March 2026.
Summary According to the enemy release hypothesis (ERH), the fitness of exotic plants and their capacity to become invasive in their area of introduction may partly be attributable to the loss of their natural enemies. Invasive species may also benefit from modifying soil attributes and thereby creating a positive soil–plant feedback.

Migration and Attacking Ability of Bursaphelenchus mucronatus in Pinus thunbergii Stem Cuttings

The Plant Pathology Journal, 2016
To understand how Bursaphelenchus xylophilus kills pine trees, the differences between the effects of B. xylophilus and B. mucronatus on pine trees are usually compared. In this study, the migration and attacking ability of a non-pathogenic B. mucronatus

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 ...

Inhibition of Bursaphelenchus xylophilus Migration at the Nodes of Pinus thunbergii

Journal of the Japanese Forest Society, 2010
クロマツにおける節の存在や形態がマツノザイセンチュウ (以下, 線虫) の移動に与える影響を明らかにするため, 節の条件が異なるクロマツ切り枝に線虫を接種し, 通過数を調べた。また, 節における皮層樹脂道の形態を観察した。さらに, クロマツ苗木に線虫を接種し, 輪生枝数と病徴進展との関係を調べた。通過線虫数は, 節の無い切り枝よりも節のある切り枝で少なく, さらに節の輪生枝が多い切り枝ほど少なかった。このことから, クロマツの節では線虫の移動が抑制され, その効果は輪生枝数が多いほど強いことが明らかになった。また, 節付近では, 皮層樹脂道の結合や走行方向のわん曲がみられ, 節から離れた部位よりも節の皮層樹脂道の横断面は小さく, 数も少なかった。このような節の皮層樹脂道の形態が ...

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.

Ascarosides coordinate the dispersal of a plant-parasitic nematode with the metamorphosis of its vector beetle

Nature Communications, 2016
Many species of nematodes use pheromones called ascarosides to coordinate their behaviour and development. Here, Zhao et al. demonstrate that the beetle vector of the pinewood nematode (Bursaphelenchus xylophilus) also uses and responds to ascarosides in

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 ...

Insights into pine wilt disease: a review on biology and pathogenicity of Bursaphelenchus xylophilus and B. mucronatus

Trees, Forests and People
Pine wilt disease (PWD), caused by the pinewood nematode, Bursaphelenchus xylophilus, is a major ecological and economic threat to pine forests worldwide. Native to North America, B.

Secretome Analysis of the Pine Wood Nematode Bursaphelenchus xylophilus Reveals the Tangled Roots of Parasitism and Its Potential for Molecular Mimicry. [PDF]

PLoS ONE, 2013
Since it was first introduced into Asia from North America in the early 20(th) century, the pine wood nematode Bursaphelenchus xylophilus has caused the devastating forest disease called pine wilt.
