The Effects of Zectran on Fish and Wildlife

Goal(s)/Objective(s): Determine effectiveness of Zectran in controlling spruce budworm and evaluate any adverse effects on aquatic life and birds.
Key Findings: Zectran applied as a low volume application at a rate of 0.15 pounds per acre had no adverse effect on aquatic or bird life in the study area.

Effects of Carbaryl (Sevin) on Brook Trout in Streams Receiving Drift from Spraying of Nearby Forests

Problem Addressed: Sevin-4-oil being used against Spruce Budworm
Goal(s)/Objective(s): Monitor 1979 operational spraying to determine 1. amounts and persistence of pesticide residues in stream water, 2. the effects on the invertebrates in the benthos and drift, 3. the effect on acetylcholinesterase (AChE) activity of young trout, 4. the effect on feeding success and diet composition of young trout.
Key Findings: No major effects on the aquatic community were detected

Operational Test of Zectran (Mexacarbate) Against the Spruce Budworm (Choristoneura Fumiferana Clem.) in Maine, 1973

Goal(s)/Objective(s): Determine the efficacy of reduced application rates and dosage levels in reducing larval populations of the budworm and minimizing the amount of defoliation occurring in a given year.
Key Findings: Populations estimates made prior to treatment indicated high and relatively uniform populations in three of the four spray blocks. Block #36 had 37% fewer larvae, but the population level was high enough to cause complete stripping of current year's foliage and ultimately did so on that portion of the block that did not receive treatment.

Proposed Cooperative Project Between the Private, State and Federal Interests Concerned With Mortality and Growth Loss From Spruce Budworm Infestations

Problem Addressed: Spruce Budworm infestations
Goal(s)/Objective(s): Provide a means of evaluating the amount of damage and mortality in Maine's spruce-fir forests caused by the spruce budworm (Choristoneura fumiferana, Clem.).

Laboratory Evaluation of the Toxicity of Insecticides to Forest Insect Pests and Non-Target Insects in 1986

Problem Addressed: Use of the insecticide SAN 811-I
Goal(s)/Objective(s): Determine the persistence of a new insect growth regulator, UC 84572 in aquatic systems.
Key Findings: Permethrin appears to be 1-2 orders of magnitude more toxic than methoxychlor by either exposure route.

Fenitrothion Residues in Honeybees and Their Products Collected From Forested Areas Sprayed with the Insecticide for Budworm Control

Problem Addressed: Fenitrothion effects on honeybees
Goal(s)/Objective(s): Results and observations made in an extensive three-year study program undertaken in 1972 to determine the effect of fenitrothion applied by aircraft at operational levels on honeybees and its residues, if any, in 122 honeybee, pollen, beeswax and honey samples collected from sprayed forest areas in the provinces of Ontario and Quebec.

Plantation Research: XII. Experimental Applications of Insecticides by Mistblower for Control of Choristoneura fumiferana on White Spruce in Quebec, 1974

Problem Addressed: Spruce Budworm
Key Findings: Applications of commercial preparations of Bacillus thuringiensis at up to 8 BIU per acre did not provide significant levels of foliage protection when timed against peak third-instar larvae.
