Culturing Bursaphelenchus cocophilus in vitro and in vivo

Nematoda, 2018
Red ring disease (RRD) is of particular importance in many African oil palms- and coconut-producing regions in Central and South America and the Caribbean. Its causal agent, the nematode Bursaphelenchus cocophilus (Cobb) Baujard, causes extensive damage to tissues in the plant trunk that typically leads to plant death within months.

Morpho-biometrical characterisation of Portuguese Bursaphelenchus xylophilus isolates with mucronate, digitate or round tailed females

Phytopathologia Mediterranea, 2009
Morpho-biometrical studies were conducted on 12 Bursaphelenchus xylophilus isolates collected from maritime pine, Pinus pinaster, in Portugal. The studies were carried out on 20 females and 20 males from each isolate. A wide variation in the female tails,

Bursaphelenchus suri n. sp.: A second Bursaphelenchus syconial parasite of figs supports adaptive radiation among section Sycomorus figs.

PLoS ONE, 2022
The nematode genus Bursaphelenchus is a highly divergent group. This genus mainly consists of mycophagous entomophilic species, but some species have specialized as obligate or facultative plant parasites, facultative insect parasites, or exhibit feeding

Nematodes in the Pine Forests of Northern and Central Greece

Insects, 2022
In the context of plants or plant products protection by harmful organisms, measures have been taken by EU countries in order to prevent their introduction and establishment into the EU, and also limit their expansion in case they do enter.

Aphelenchoididae nematodes in a centennial Pinus pinea tree, and a review of Bursaphelenchus species from this host

Phytopathologia Mediterranea
A “monumental” centennial Pinus pinea L. tree of public interest with severe wilting symptoms was felled in Coimbra, Portugal. A survey was carried out to detect Aphelenchoididae nematodes (including Bursaphelenchus spp.) in the tree tissues.

Genetic characteristics of Bursaphelenchus xylophilus third-stage dispersal juveniles

Scientific Reports, 2021
The third-stage dispersal juvenile (DJ3) of pinewood nematode (PWN) is highly associated with low-temperature survival and spread of the nematode. Oil-Red-O staining showed that its lipid content was significantly higher compared with other PWN stages ...

A conceptual model for the diapause intensity curve and termination in overwintering Japanese pine sawyer larvae, Monochamus alternatus (Coleoptera: Cerambycidae)

Physiological Entomology, Volume 51, Issue 2, Page 226-236, June 2026.
Larval diapause intensity of Monochamus alternatus follows a declining curve, beginning with an initial refractory phase and reaching termination after approximately 110 days of chilling at 9°C. Residual inhibitory state strongly influenced post‐chilling development; additional chilling shortened the diapause period more at 18°C than at warmer ...

Standardized Protocols for Soil Fauna Extraction and a Call for Cross‐Lab Implementation

Ecology and Evolution, Volume 16, Issue 4, April 2026.
We present harmonized methodologies, assembled by an international group of experts, for extracting soil‐ and litter‐inhabiting nematodes, enchytraeids, microarthropods, and larger invertebrates. The protocols are illustrated with images and videos, and include advice for overcoming the most frequent issues (’expert tips’) for increasing extraction ...

Genome Assembly Resource and Annotation of Bursaphelenchus xylophilus TS-1, the Causal Agent of Pine Wilt Disease

PhytoFrontiers, 2023
Pine wilt disease is a major biological disaster caused by Bursaphelenchus xylophilus. This study establishes a high-quality and well-annotated genome sequence of B. xylophilus strain TS-1 from Mountain Tai in Shandong province, China.

Requirement of group I lytic polysaccharide monooxygenase for turnover of chitinous cuticle during moulting in two forest pest beetles, Monochamus alternatus and Psacothea hilaris

Insect Molecular Biology, Volume 35, Issue 2, Page 115-125, April 2026.
Group I LPMO15‐1 cDNAs from two economically important forest insect pests, M. alternatus and P. hilaris, were cloned. MaLPMO15‐1 and PhLPMO15‐1 show a similar pattern of expression during late stages of development. RNAi for LPMO15‐1 causes failure of adult eclosion in both M. alternatus and P. hilaris.
