Plain Language Summary

Spruce budworm is the most destructive native forest defoliator in North America. Outbreaks of this budworm occur every 30-40 years, with high levels of defoliation persisting for 10 years during an outbreak. This document describes the life cycle, appearance, damage and control measures available for managing spruce budworm outbreaks. The early intervention program helps the natural enemies of budworm keep budworm populations at low levels with the judicious use of pesticides.
