A spatio-temporal multi-scale fusion algorithm for pine wood nematode disease tree detection

Journal of Forest Research
Pine wood nematode infection is a devastating disease. Unmanned aerial vehicle (UAV) remote sensing enables timely and precise monitoring. However, UAV aerial images are challenged by small target size and complex surface backgrounds which hinder their ...

Genome and transcriptome‐based identification and expression profiling of chemosensory gene families across developmental stages and tissues in Sirex noctilio (Hymenoptera: Siricidae)

Insect Molecular Biology, Volume 35, Issue 3, Page 270-283, June 2026.
The first draft genome of Sirex noctilio was produced. Fifteen S. noctilio transcriptomes were sequenced to study chemosensory gene expression patterns. SnocOR16 and SnocSNMP1 displayed tissue‐ and sex‐specific expression patterns. Abstract The Sirex woodwasp (Sirex noctilio; Hymenoptera: Siricidae) is among the most destructive invasive pests ...

Two Nematicidal Compounds from Lysinimonas M4 against the Pine Wood Nematode, Bursaphelenchus xylophilus

Forests, 2022
A rich source of bioactive secondary metabolites from microorgannisms are widely used to control plant diseases in an eco-friendly way. To explore ideal candidates for prevention of pine wilt disease (PWD), a bacterial strain from rhizosphere of Pinus ...

On the vulval morphology of some species of Bursaphelenchus (Nematoda: Parasitaphelenchinae) [PDF]

, 2009
The vulval pattern of six species of the genus Bursaphelenchus (B. abruptus, B. conicaudatus, B. fraudulentus, B. luxuriosae, B. mucronatus and B. xylophilus) was studied using scanning electron microscopy.

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 ...

Distinct biogeographic patterns for bacteria and fungi in association with Bursaphelenchus xylophilus nematodes and infested pinewood

Microbiology Spectrum
Pinewood nematodes (PWN, Bursaphelenchus xylophilus) are destructive plant parasitic nematodes that cause pine wilt disease (PWD) by attacking the vascular systems of pine trees, resulting in widespread tree mortality.

Calcium leakage involved in nematotoxic effects of the Conidiobolus obscurus CytCo protein on the pine wood nematode, Bursaphelenchus xylophilus.

Pest Management Science
BACKGROUND The pine wood nematode Bursaphelenchus xylophilus, a severe invasive species, is responsible for causing widespread pine wilt disease. The CytCo protein, a pore-forming toxin derived from Conidiobolus obscurus, exhibits nematotoxicity towards ...

Biocontrol for Shrimp Disease: Comprehensive Review and a Bacterial Disease Biocontrol Practice

Reviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Biocontrol is a key strategy for disease control, as it is environmentally friendly and widely applicable. This review elaborates on biocontrol in aquaculture, particularly in shrimp culture. Biocontrol in shrimp culture mainly relies on four strategies: (i) direct kill pathogen by Bdellovibrio or bacteriophages; (ii) suppression of intestinal
