Abstract
The size of cones and the quantity and quality of seed produced by balsam fir, Abies balsamea (L.) Mill, in five balsam woolly aphid Adelges piceae (Ratz.), damage classes were compared. No cone or seed abnormalities that could be attributed to aphid infestation or the amount of aphid damage to the trees were detected. Also, the severity of aphid damage had no influence on the incidence of damage to cones and seed caused by cone insects. No balsam woolly aphids were found on cones.Keywords
