Mobility of Forest Insects

Problem Addressed: Forest insects
Goal(s)/Objective(s): Discuss the mobility of forest insects.
Key Findings: Replace where possible current protection strategies with more aggressive strategies that aim at the prevention of pest damage, for the future of forestry in Canada.

A Study of the Cost of Strip Cutting Black Spruce Stands in Northern Ontario

Problem Addressed: Spruce budworm
Goal(s)/Objective(s): Deal with the impact of strip cutting on planting, layout and supervision, in-strip operations, roadside processing, movement of mean and materials, and roads.
Key Findings: While the effects of strip cutting on silvicultural treatment costs are not included in the terms of reference of this study, discussions with foresters suggest that there may be some.

Summary Report on Studies of the Impact of Insecticides on Forest Ecosystems

Problem Addressed: Insecticide impacts on forest ecosystems
Goal(s)/Objective(s): Examine forest songbird responses to timber stand alterations in Eastern Canada caused by spruce budworm damage over the past decade.
Key Findings: In areas where the budworm-killed conifer component is being replaced by a new forest growth, songbird density is comparable to that in adjacent undamaged stands, but songbird diversity is considerably lower than in nearby unaffected stands.

Insecticide Trials to Control Spruce Budworm Damage on Christmas Trees

Problem Addressed: Spruce budworm and use of insecticides effecting Christmas trees
Goal(s)/Objective(s): Describe the tests of experimental applications of three chemicals to provide data for new registrations.
Key Findings: Fall and winter predictions of high populations and potential heavy budworm damage in southern Maine were inaccurate.

Effects of Insecticides

Problem Addressed: Effects of insecticides
Goal(s)/Objective(s): Organize remarks on 'the pesticide problem' and pesticides effects on non-target organisms.
Key Findings: Adopting ecologically sound insect-pest management using modern integrated control systems will help reduce genetic toxicity to experimental animals and will work against how insecticides are frequently counterproductive in achieving the intended objective of controlling insect populations.

The Role of the Sex Pheromone in the Management of Spruce Budworm

Problem Addressed: Outbreaks of the eastern Spruce budworm
Goal(s)/Objective(s): Develop strategies aimed at the prevention of outbreaks using pheromone baited traps.
Key Findings: The capability of the synthetic sex pheromone of C. fumiferana in reducing the production of fertile eggs, and hence its potential as a weapon for managing spruce budworm populations is still largely unknown.

The Significance of Non-Host and Alternative Host Tree Species on Populations of Larval and Spruce Budworm, with Emphasis on Improving Sampling Techniques

Problem Addressed: Spruce budworm
Goal(s)/Objective(s): Evaluate spruce budworm population and defoliation levels on host species of differing forest types in Maine.
Key Findings: Spruce budworm moths showed a distinct preference for white spruce foliage. Egg to instar-VI budworm survival was highest in the forest type which was a mixture of white spruce and balsam fir. Survival was lowest in the study area with a mixture of red spruce, balsam fir, and hemlock.
