Agent-based simulation of effects of stress on forest tent caterpillar (Malacosoma disstria Hübner) population dynamics

► We model population dynamics of the forest tent caterpillar (FTC) and parasitoid. ► We determine how stress may alter demographic parameters of each insect. ► We monitor how such changes affect intensity or frequency of forest defoliation. ► We find certain parameters altered length, frequency or intensity of defoliation. ► We find parasitoid efficiency most effective in altering FTC forest defoliation.
