Trophic interactions of Forest Tent Caterpillars in temperate and boreal forests of Quebec
In hardwood and mixed boreal forests, Forest Tent Caterpillars (Malacosoma disstria) (FTC) constitute an important defoliator of sugar maples (Acer saccharum) and trembling aspen (Populus tremuloides). Severe and periodic outbreaks can reduce tree growth and can lead to tree mortality, as well as a diminution of forest productivity. It is imperative to understand factors regulating population dynamics of FTC and the effect of its outbreaks on forest ecosystems. Of the poorly understood aspects of these outbreaks, the effects of predators on FTC population and how they influence forest regeneration.
