Abstract

Survival of the balsam woolly aphid on Abies grandis logs was observed to evaluate the danger of spreading the pest while moving logs. Active stages of the aphid survived submergence in sea water for 7 days and periodic sprinkling with sea water for 3 weeks. Dormant stages survived submergence up to 28 days. Active aphids survived on logs in the forest as long as 5 months. Crawlers frequently re-established on logs and completed a second generation there. Dormant neosistentes on autumn-felled trees persisted over winter and resumed development in the spring. Recommendations for moving infested logs through uninfested areas are made.
