► Abstract
During the forest tent caterpillar outbreak in the late 1970s, sequential egg mass surveys were conducted to predict outbreaks. At each site, up to 10 branches on up to 10 trees were examined to count the number of forest tent caterpillar egg masses. Once a threshold number of egg masses was reached, defoliation was predicted and no more branches needed to be surveyed. In 1978, additional data were collected on root starch and root sap sugar content to help predict risk to tree health from past and future defoliation.
