The Spruce Budworm in Maine in 1951

Problem Addressed: Spruce budworm in Maine
Goal(s)/Objective(s): Provide information on ground, aerial, and egg mass surveys, special studies of the effect of environment and natural control factors on budworm populations, and rearing of parasites.
Key Findings: Populations of large larvae and pupae were considerably less in most of the observation points and in the special study plots.
Recommendation: Although no spraying will be recommended for 1952 in Maine the State and timberland owners should continue to be prepared to combat the past if it increases to outbreak proportions.

Compendium of Eastern Spruce Budworm Program Status Reports for the Eastern Canadian Provinces and Maine

Problem Addressed: Spruce budworm
Goal(s)/Objective(s): Describe budworm research projects being planned for initiation prior to June 30, 1980.
Key Findings: Sevin-4-Oil, or one or more of its constituents, potentiates the virus Herpes virus varicellae, the causative virus in chicken pox and "shingles".

Effects of Forest Insect Spraying on Northern Maine Trout Streams

Problem Addressed: Spruce budworm effects
Goal(s)/Objective(s): Study the effects of DDT spraying on fish populations in the treated area.
Key Findings: Populations of brook trout and other fishes were reduced considerably by DDT spraying in 1958.

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
