Other claims from this paper (9)
- Observation Cortical resin canals were the sole initial invasion pathway for PWN.
- Observation Low inoculation levels permitted invasion through resin canals within one hour.
- Observation Optimal bark migration in two-year-old branches reached 15 cm upward and 18 cm downward by 12 hours.
- Observation Approximately 11.7% of inoculated nematodes migrated in branch bark by 12 hours.
- Intervention effect Migration did not differ between natural beetle-feeding and artificial wounds within 12 hours.
- Intervention effect Branch cross-sections accelerated bark migration to 17 cm within six hours compared with an 8 cm maximum in other wounds.
- Intervention effect Branch cross-sections accelerated xylem migration to 16 cm within six hours compared with an 8 cm maximum in other wounds.
- Intervention effect Wounds exposed for at most 12 hours permitted invasion; longer exposure reduced or prevented invasion.
- Recommendation The first 12 hours after wounding represent the key vulnerability period for targeted disease prevention.
