Results of Spray Operations Against Spruce Budworm in New Brunswick 1977 and a Forecast of Conditions in the Maritimes for 1978

Goal(s)/Objective(s): Give the results of aerial spraying operations in New Brunswick in 1977 which were carried out to limit damage caused by the spruce budworm

Key Findings: Best results, in terms of foliage saved and percent budworm killed, occurred in areas treated twice with aminocarb, three times with one application of fenitrothion and two applications of aminocarb, and once with fenitrothion at 4 oz per acre, when the budworm was in the fourth instar.

Cooperative Spruce Budworm Suppression Project Maine, 1979 Final Environmental Statement

Problem Addressed: Spruce Budworm Infestation

Goal(s)/Objective(s): Keep tree mortality at an acceptable level

Key Findings: Overall objectives of the 1978 spray project were not met, primarily because adverse weather delayed application of the insecticides.

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.

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.
