Pacific Pests, Pathogens and Weeds


  • Worldwide distribution. In Australia, New Zealand, most Pacific island countries.
  • Major pest causing tunnels and staining in distressed, fallen trees and sawn timber. All stages completed inside tunnels, feeding on fungus introduced by adults as they bore.
  • Spread: adults emerge and fly short distances. Longer distance spread with domestic and international movement of logs and timber.
  • Biosecurity: high chance of introduction in logs and timber. Countries yet free should set traps at ports, and ensure crates, pallets and dunnage compliant with international standard: (
