What's eating my brazilian araucaria?

Brazilian Araucaria (Araucaria angustifolia) is attacked by scale insects, aphids, and bark beetles outdoors. The edible seeds attract birds, squirrels, and other wildlife. Young trees may be browsed by deer. Scale and wood-boring insects on stressed or drought-affected trees cause the most significant landscape damage.

Hard or soft bumps encrusting stems and needles; yellowing foliage; sooty mold on honeydew Horticultural oil sprays in late winter and early summer; scrape off heavy infestations manually; keep trees well nourished to improve resistance

Resin seeping from bark; small round exit holes; upper branch dieback particularly on drought-stressed trees Maintain adequate irrigation; avoid bark wounds; remove and destroy infested branches; biological controls limited once larvae are inside

Seeds stripped from maturing cones before harvest; cones may be carried off whole Harvest cones as soon as they ripen; netting can protect individual trees; difficult to exclude wildlife at scale
