Environmental Impact and Efficacy of Imidan Used for Spruce Budworm Control in Maine

Problem Addressed: Spruce budworm

Goal(s)/Objective(s): Determine environmental impact and efficacy of Imidan as use as insecticide against spruce budworm

Key Findings: There is an apparent lag of between 7 and 14 days following spray before mortality rates are greater than observed in unsprayed areas. There is an apparent larval feeding deterrent action produced by the chemical.

Spruce Budworm on Christmas Trees

Problem Addressed: Spruce budworm and use of insecticides effecting Christmas trees

Goal(s)/Objective(s): Control of insects on Christmas trees

Key Findings: Trees damaged by budworm or other insects should not be cut because if they are left for a few years they will often recover and become suitable for Christmas trees.

Photometric Derivation of Analytical Parameters for Large Area Forest Management

Problem Addressed: Spruce budworm infestation in northeastern Canada and the United States

Goal(s)/Objective(s): Derive photometric parameters from historical satellite (Landsat) data toward an ultimate objective of aiding large area forest managers to cope with the massive spruce budworm infestation in northeastern Canada and the United States.

Key Findings: Use of satellite data (Landsat MSS) to measure and predict mortality as well as other analytical parameters related to coniferous forest management appears technically feasible.

Recommendation: A development effort be initiated with Maine's Department of Conservation to complement Maine's present Landsat Demonstration Program with the National Aeronautics and Space Administration for establishment of a mechanism for small forest landowners to benefit from satellite data.

Planning Now to Reduce, Postpone or Prevent the Next Spruce Budworm Outbreak

Problem Addressed: Spruce budworm

Goal(s)/Objective(s): Introduces new entomological concepts, and asks as well as suggests how they may be used to develop an international strategy to reduce, postpone or perhaps even prevent future outbreaks from occurring through at least part of the range of the spruce budworm in North America

Key Findings: Ten general characteristics of spruce budworm infestation in Ontario are presented

Sex-Biased Predation by Web-Spinning Spiders (Araneae) on Spruce Budworm Moths

Problem Addressed: Spruce budworm

Goal(s)/Objective(s): Describe predation by several species of web-spinning spiders on moths of C. fumiferana in Maine, compare differential mortality between moth sexes, and discuss possible factors that contribute to sex-biased predation on male moths

Key Findings: Predation by spiders gains increased importance as a source of moth mortality.

Impact of the Spruce Budworm on Spruce-Fir Stands in the Sault Ste. Marie and St. Ignace Districs of the Hiawatha National Forest 1978-1981

Problem Addressed: Spruce budworm in Michigan

Goal(s)/Objective(s): Documents the budworm impact on the eastern unit of the Hiawatha National Forest, the Sault Ste. Marie and St. Ignace Districts of the Ottawa National Forest for 1978, 1979, 1980, and 1981.

Key Findings: Statistics presented provide an estimate of spruce budworm impact on spruce-fir stands in the Sault Ste. Marie and St. Ignace Districts from 1978-1981.

Brook Trout Studies in the Icewater Creek Watershed

Problem Addressed: Insecticides effecting the environment

Goal(s)/Objective(s): Examine in-depth a number of aquatic and terrestrial habitats and micro-habitats and their resident animal populations to determine the nature and degree of inherent risk, the level of actual exposure, and the actual response to forest pest management strategies involving aerial applications of pest control agents.

Brook Trout Population Study on Zectran Sprayed Area 1967

Problem Addressed: Spruce budworm control

Goal(s)/Objective(s): Determine effectiveness of Zectran for control of the spruce budworm, and effects on trout populations.

Key Findings: The application of Zectran at 0.15 pounds per acre appears to have had no immediate adverse affects on the trout populations in the sample sections.
