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.

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.

Assessment of Harvest Characteristics and Silvicultural Outcomes Survey: A Component of the Maine Forest Service Multi-Resource Harvest Assessment Protocol

Problem Addressed: Classifying harvested stands
Goal(s)/Objective(s): Testing and refining a method for classifying forest harvests in Maine
Key Findings: The sampling approach proved reliable under a wide range of harvested stand conditions.
Recommendation: The classification system offers a new approach to objectively classify forest harvests.

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.

Final Report on The Effects of Forest Spraying on Reproduction in Smallmouth Bass Populations in Washington County

Problem Addressed: Smallmouth bass waters lie within the proposed spray area for operational control of spruce budworm
Key Findings: No direct fish mortality or physiological and behavioral responses were observed because of the doses used, the low toxicity, and the avoidance of direct application in the lake.
