The eastern spruce budworm is believed to be the most damaging forest insect in Maine and North America. Outbreaks of the insect that kills balsam fir and spruce trees occur every 30 to 60 years.
Severe defoliation already has occurred in southern Quebec; we expect to see outbreak populations of SBW in Maine beginning within the next 3 years. Beginning in current-year defoliation was quantified using the Fettes Method on a subset of MFS-sampled L2 sites and additional sites in northern Maine.
This method provides a systematic approach to measuring defoliation. It was employed during the last budworm outbreak in Maine. History. The first recorded outbreak of the (eastern) spruce budworm in the United States occurred in Maine in aboutalthough it seems to have escaped notice of the entomologists until Another outbreak followed in Since there have been waves of budworm outbreaks throughout the eastern United States and : Insecta.

Classes presented from least vulnerable (Non-host Forest) to most vulnerable (Fir-Dominated Host Forest. Entomologists suggest an outbreak occurs every 30 years or so. The province of Quebec has been battling the spruce budworm for several years, and in the provincial government committed $33 million for additional aerial insecticide spraying in hopes of limiting the damage to its forests and, subsequently, the forest products industry.
Spruce budworm (SBW; Choristoneura fumiferana (Clem.)) defoliation can cause severe growth reduction and mortality to spruce-fir (Picea-Abies) species in eastern North uently, it is important to understand and predict how individual trees respond to defoliation in terms of growth and mortality. in Association with Early-Instar Spruce Budworm in Maine 18 Notes on Abundance, Biology, and Comparison of Spruce Budworm Parasites in Maine 20 Egg Parasites 20 Larval Parasites 20 Pupal Parasites 24 Acknowledgments 28 Literature Cited 28 Appendixes 30 General External Morphology of a Parasitic Wasp, Glypta fumiferanae (Viereck) 30 Glossary e Maine Spruce Budworm Task Force was formed in summer by the University of Maine’s Cooperative Forestry Research Unit (CFRU), Maine Forest Service (MFS), and Maine Forest Products Council (MFPC) to begin preparing for the next outbreak of the eastern spruce budworm.
