Utilization of Budworm Killed Spruce and Fir in Full Scale Sulfite Processing
Problem Addressed: Production of fully bleached market sulfite pulp and spruce budworm's effect on it.
Goal(s)/Objective(s): Outline some of the wood utilization techniques now in place and discuss the effect of budworm killed wood on product quality.
Key Findings: The increasing consumption of budworm killed wood at Nova Scotia Forest Industries shows no deleterious effect on pulp strength properties for bleached sulfite market pulp.

Problem Addressed: Aminocarb presence after spraying
Goal(s)/Objective(s): Highlight the presence and persistence of three formulations of Aminocarb spraying.
Key Findings: Residues in litter were higher and persisted longer than in soil.

Problem Addressed: Spruce budworm defoliation of balsam fir.
Goal(s)/Objective(s): Quantify defoliation levels in treated and control plots in order to determine what effect, if any, thinning had on the susceptibility of balsam fir.
Key Findings: Susceptibility of balsam fir to spruce budworm defoliation was not affected after thinning in coniferous and hardwood forest types.

Problem Addressed: Insecticides
Goal(s)/Objective(s): Summarize 1986 insecticide field efficacy.
Key Findings: In the field, budworm populations develop slightly slower on black spruce than on white spruce or balsam fir.

Problem Addressed: Environmental impacts from forest management and processes.
Goal(s)/Objective(s): Give an appreciation of the types of environmental impacts that are associated with spruce budworm management and to demonstrate that pests can be managed in several ways, each with different impacts.
Key Findings: Environmental impacts depend on not only management strategy and insecticide but also on application rate, formulation, spray timing and block layout.

Problem Addressed: Spread of spruce budworm larvae.
Goal(s)/Objective(s): Describe a new sticky-board traps for measuring early-larval dispersal of the spruce budworm, Choristoneura fumiferana (Clem.), and evaluates trap-board color and screen versus unscreened traps.
Key Findings: Dispersing spruce budworm larvae showed no preference for trap color; fewer nontarget arthropods were caught ondark-colored than on light-colored traps. Screened traps caught significantly more spruce budworm larvae than unscreened traps, and they were easier to examine.

Problem Addressed: Effects of insecticides
Goal(s)/Objective(s): Summary of EPA's evaluation of the pesticide carbaryl, and weight the risks of using a pesticide against its economic and social benefits.
Key Findings: Carbaryl is a registered pesticide which has been demonstrated not to cause unreasonable adverse effects when used in accordance with commonly recognized practices.

Problem Addressed: Spruce budworm
Goal(s)/Objective(s): See if areas of spruce-fir containing mixtures of various species of hardwoods would also harbor (1) lower populations of budworm, and (2) greater percentages of parasites.
Key Findings: Spruce budworm populations were much lower in areas containing predominantly hardwoods mixed with some spruce and fir.

Problem Addressed: The unknown character of the presettlement forests in New England.
Goal(s)/Objective(s): Estimate the species composition of the presettlement forests, to interpret their successional status, and to provide evidence on the frequency of large-scale natural disturbances.
Key Findings: Severe disturbance was fairly common in the presettlement forest of northern Maine, and data from the land surveys and individual virgin stands likewise indicate that most of the land surface supported climax stands that were frequently all-aged.
