- Title
Forest fragmentation and colony performance of forest tent caterpillar

- Abstract
We monitored survival and egg production in colonies of Malacosoma disstria Hubner in the understorey to examine relationships between colony performance and forest structure at several spatial scales. As forest cover increased, fewer moths survived. Increased mortality froma virus and a parasitoid assemblage were the main causes of this result. Forest cover measured at the smallest spatial scale (53m x 53m) was the best predictor of colony performance. We attribute these effects of fragmentation to fine-scale differences in microclimate betweeen edge and interior habitats (edge effects).
