Research Progress on the Early Monitoring of Pine Wilt Disease Using Hyperspectral Techniques

Sensors, 2020
Pine wilt disease (PWD) caused by pine wood nematode (PWN, Bursaphelenchus xylophilus) originated in North America and has since spread to Asia and Europe. PWN is currently a quarantine object in 52 countries.

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 ...

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

Physiological Entomology, EarlyView.
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 ...

The Vulnerability of New Zealand Forage Plants to Incursions by New Pests, Pathogens and Weeds, and the Case for Greater Protection

New Zealand Journal of Agricultural Research, Volume 69, Issue 1, February 2026.
We outline the diversity of pests, weeds and plant pathogens absent from New Zealand that threaten forage production, examine their potential import pathways, and outline the challenges of managing them should they arrive. The number and diversity of threats and pathways indicates ongoing incursions are inevitable.

From beginning to end: the synecology of tree‐killing bark beetles, fungi, and trees

Biological Reviews, Volume 101, Issue 1, Page 314-335, February 2026.
ABSTRACT Over a century of research has revealed an amazing complexity of behaviours and physiological adaptations that allow tiny bark beetles to overcome large trees, sometimes resulting in outbreaks that kill millions of trees. Turning a tree into a home and successfully raising offspring involves constant interactions among the beetles, the tree ...
