Water potential of Fraser fir infested with balsam woolly adelgid (Homoptera: Adelgidae)
Environmental Entomology 15 (4), 911-913
Abstract: Water potential of Fraser fir infested with the balsam woolly adelgid, Adelges piceae (Ratzeburg), and uninfested controls was evaluated using a Scholander pressure chamber. Field measurements were taken at three locations (Mt. Rogers, VA.; Roan Mountain, Tenn.; and Mt. Mitchell, N.C.) during the 1984 growing season. June measurements at Roan Mountain and Mt. Mitchell showed that infested trees were lower in water potential than uninfested controls, but there were no significant differences in midsummer at all three sites. Infested trees at all three sites showed a lower water potential when measured in September. Increment cores taken from infested trees at all three sites contained abnormal xylem (rotholz), and nearly all cores from uninfested trees at Mt. Mitchell also contained rotholz.
