Long range effect on Aspen of defoliation by the forest tent caterpillar
Minnesota Forestry Notes
In 1961, after an earlier comprehensive investigation (1) of the effects on aspen (Populus tremuloides Michx.) of defoliation by the forest tent caterpillar (Malacosoma disstria Hbn.) a second study was undertaken. The objectives were: to define the conditions, if any, under which aspen mortality could be attributed to defoliation; to ascertain whether increased disease or insect attack followed defoliations; to evaluate the effects of defoliation upon subsequent growth.
