Pine wilt disease: Biosecurity readiness for New Zealand’s plantation forestry

RosemaryM@nzfoa.org.nz (Rosemary McFadyen) — Tue, 23 Sep 2025 10:51:47 +1200

This report assesses New Zealand’s biosecurity readiness for pine wilt disease (PWD), caused by the nematode Bursaphelenchus xylophilus. PWD spreads via Monochamus beetles and causes rapid pine mortality; Pinus radiata may be more susceptible than previously thought. Though not present in NZ, border interceptions and climate suitability raise concern. The report outlines surveillance, diagnostics, and control strategies including remote sensing, biocontrol, and resistance breeding. It aims to guide preparedness planning to protect NZ’s forestry sector from potential PWD incursions.

Ips grandicollis and other bark beetles: Biosecurity readiness for New Zealand’s plantation forestry

RosemaryM@nzfoa.org.nz (Rosemary McFadyen) — Tue, 23 Sep 2025 10:50:28 +1200

Ips grandicollis, a bark beetle native to North America and now established in Australia, poses a significant biosecurity threat to New Zealand’s Pinus radiata plantations. This comprehensive report assesses the beetle’s biology, global spread, and risk factors, highlighting its potential to cause widespread tree mortality and timber degradation, especially under climate stress. It outlines surveillance, control, and management strategies, including chemical, biological, and silvicultural options, and recommends a national readiness plan to mitigate incursion risks. The report emphasizes the need for improved diagnostics, trap networks, and coordinated response protocols to protect New Zealand’s forestry sector.

Lecanosticta acicola: Biosecurity readiness for New Zealand’s plantation forestry

RosemaryM@nzfoa.org.nz (Rosemary McFadyen) — Wed, 24 Jul 2024 15:52:52 +1200

Lecanosticta acicola, the fungal pathogen causing brown spot needle blight (BSNB), poses a serious biosecurity threat to New Zealand’s Pinus radiata plantations. Though not yet present, NZ’s climate is highly suitable for its establishment and spread. This report reviews global outbreaks, host susceptibility, and dispersal mechanisms, highlighting risks from tourism, forestry equipment, and climate change. It outlines surveillance, diagnostics, and control strategies including copper fungicides, silviculture, and resistance breeding. Recommendations include readiness planning, enhanced surveillance, diagnostic upskilling, and international collaboration to safeguard NZ’s forestry sector.
