Tent Caterpillars on Apple: Tree Health Over Spray

Tent caterpillars defoliated apple tree last year, no fruit. Healthy trees tolerate defoliation. Fruit failure likely pollination issue.

Management

1. Prune out tents early.
2. Bt spray if heavy on young trees.
3. Ensure pollinators: plant flowers, avoid sprays at bloom.
4. Thin fruit for quality.
