Analysis of the 1979 Check Cruise of the Maine Spruce Budworm Growth Impact Study

Problem Addressed: Double checking the accuracy and uniformity of measurements between and among crews providing data to the Maine Spruce Budworm Growth Impact Study
Goal(s)/Objective(s): Report the analysis of the check cruise data obtained during August and September, 1979.
Key Findings: Results of the 1979 check cruise appear to be comparable to those of the 1975 check cruise conducted by James W. Sewall Company

A Technical Review of Planning and Guidance Procedures in Maine’s Spruce Budworm Spray Operation with Recommendations for Refined Spray Application

Problem Addressed: Implementing a more refined spraying program for control of spruce budworm damage in Maine.
Goal(s)/Objective(s): Review present spray operation procedures and offer suggestions for dealing with the problems inherent in each stage.
Key Findings: A Loran-C based electronic guidance system used in conjunction with visual guidance in well planned blocks under the supervision of proficient, experienced guides and monitors is recommended for future spray operations

A History of Recent Infestations of the Spruce Budworm in Northwestern Ontario, and an Estimate of Resultant Timber Losses

Problem Addressed: Spruce Budworm infestations in the Lac Seul and Lake Nipigon regions of northwestern Ontario
Goal(s)/Objective(s): Make deductions which indicate when the first severe defoliation occurred.
Key Findings: The potential for future losses within the areas affected by 1955 is almost double the amount destroyed.

A Review of Entomological Survey and Assessment Techniques used in Regional Spruce Budworm, Choristoneura fumiferana (Clem.) Surveys and in the Assessment of Operational Spray Programs

Problem Addressed: Spruce Budworm
Goal(s)/Objective(s): Ensure on a technical level the general principles of survey and assessment techniques were understood and evaluated in a manner unlikely to cause problems between jurisdictions, and create a sufficient standardization of techniques to allow a realistic comparison of results across jurisdictions.
Key Findings: Differences which existed were only minor and usually reflected modifications to suit local conditions or needs and standardization seemed unnecessary.
