Lifecycle
Adults emerge mid-May through August, with peak activity in early June. Females lay 65-90 eggs on bark surfaces. Larvae hatch in 7-10 days, bore into cambium, and create S-shaped galleries. Larvae overwinter in shallow sapwood chambers, pupating in late April to early May. Complete development takes one year.
Professional Treatment Approach
Early detection through regular monitoring and inspection
Preventive systemic insecticide treatment with emamectin benzoate
Apply treatments before peak adult emergence in May
Annual or biennial treatment programs for high-value trees
Remove and destroy heavily infested trees to reduce beetle populations
Professional diagnosis recommended for proper treatment timing
