Patterns of Tree Mortality During an Uncontrolled Spruce Budworm Outbreak in Baxter State Park, 1983

Problem Addressed: Uncontrolled spruce budworm outbreak
Goal(s)/Objective(s): Study the patterns of mortality in balsam fir and in the red-black spruce complex during an uncontrolled spruce budworm outbreak
Key Findings: The hypotheses on the mechanisms producing the tree mortality patterns during a budworm outbreak were summarized and the observed tree mortality patterns were then interpreted according to those hypotheses.

Predators of the Spruce Budworm (1985)

Problem Addressed: Spruce budworm
Goal(s)/Objective(s): 1. Review available information on the predators of the spruce budworm; 2. Provide information on predator biologies, including life stages, modes of attack, and general importance; 3. Summarize the importance of predators and predation in population dynamics of the spruce budworm; 4. Review forest-management practices that enhance predator populations; and 5. List basic literature sources for identifying predators of the spruce budworm.
Key Findings: The information in the article is especially needed at low population levels of the pest so that we can learn how to manage the forest to prevent future outbreaks.

Pilot Control Project to Determine Efficacy of Acephate, Carbaryl, and Trichlorfon Against the Spruce Budworm (Choristoneura fumiferana (Clem.)) in Maine — 1976

Problem Addressed: Insecticide use against spruce budworm
Goal(s)/Objective(s): Conduct a pilot control project to evaluate the efficacy of three different insecticides in reducing larval populations of the budworm and minimizing the amount of defoliation to host trees.
Key Findings: Each of the insecticides could be effectively used against the spruce budworm with minimal and transitory effects on the environment.

Harvesting Systems for Silvicultural Control of Spruce Budworm (1979)

Problem Addressed: Damage done by spruce budworm
Goal(s)/Objective(s): Using silviculture playing a major role in an integrated protection management program for reducing damage by the spruce budworm.
Key Findings: An analysis of a proposed partial cutting on a small private woodlot in southern Piscataquis County shows that shortwood methods, using the landowner's small farm tractor, are preferable in this case
