DescriptionInfestations of the balsam woolly aphid, Adelges piceae (Ratz.), on European silver fir trees in a plantation were observed over a 7-year period. Infestations were usually light, but occasionally increased to heavy. Heavy infestations declined within 1 or 2 years without killing the trees or causing them apparent damage.
