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.

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.

Chemical Accountability of Forest Pest Control Products

Problem Addressed: Chemical effects of forest pest control products on other parts of the forest

Goal(s)/Objective(s): Review methods development for forestry chemicals at residue levels and environmental chemistry (distribution, persistence, movement, fate, etc.) of these chemicals in different components of the forest.

Controlling Hardwood Sprouts with Foliage Sprays

Problem Addressed: Controlling unwanted hardwood reproduction

Goal(s)/Objective(s): A more effective, less destructive way to deal with the unwanted hardwood reproduction is necessary.

Key Findings: For forest management, fairly low percent kill with decreased rate of regrowth for 2 or 3 seasons may be adequate to give pine the release it needs.

The Spruce Budworm in Maine in 1972

Problem Addressed: Spruce budworm in Maine

Goal(s)/Objective(s): Determine what to do to combat the spruce budworm issue.

Key Findings: Ground and aerial surveys and airport procedures were conducted as reported in preceding reports by many of the same personnel, but with a change from a centralized to a regionalized system of administration.

Measurement and Analysis of the Activity of Adult Spruce Budworm Parasitoids

Problem Addressed: Parasitoids related to the spruce budworm

Goal(s)/Objective(s): Present results of an investigation of the spatial and temporal dynamics of adults of the parasitoid Gypta fumiferanae Vierick.

Key Findings: An important factor influencing adult parasitoids and one that may be controllable is the availability of nutrients and moisture

Monitoring the Aerial Spraying of Insecticide Against the Spruce Budworm, in Quebec, in 1984

Problem Addressed: Spruce budworm insecticide effects

Goal(s)/Objective(s): Evaluate concentrations of Bacillus thuringiensis in the air of two municipalities of region 01 (St-Honoré de Témiscouata and Causapscal).

Key Findings: Spraying biological insecticides would constitute a negligible hazard to the health of the citizens nearby.
