Abstract

The hemlock looper is an important defoliator of balsam fir and outbreaks of this pest can build up very rapidly. Trees that sustain severe damage may die within a season. Researchers at the Laurentian Forestry Centre of the Canadian Forest Service have found a direct link between the activity of Telenomus, parasitoids of the hemlock looper, and the collapse of an outbreak of this pest.
