    Description

    Spruce aphid, Elatobium abietinum (Walker) (Homoptera: Aphididae), is a new invasive pest in the interior Southwestern United States. This insect is causing extensive and severe damage on dormant Engelmann spruce, Picea engelmannii Parry, and Colorado blue spruce, P. pungens Engelm., in high elevation forests in late fall and winter. Engelmann spruce is more susceptible than is Colorado blue spruce. Average mortality on heavily defoliated plots is 28-42%, with 100% mortality on some plots.
