Infestation Trends of Balsam Woolly Aphid in an Abies Alba Plantation in North Carolina

Informally Refereed

Abstract

Infestations 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.
