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

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 Cooperative Pilot Study of the Insecticide Sumithion

Problem Addressed: Insecticide effects
Goal(s)/Objective(s): Evaluate the effectiveness of a selected treatment of Sumithion in controlling the spruce budworm and the effect of Sumithion on birds, fish, and aquatic invertebrates
Key Findings: The stonefly larvae seem to have suffered the greatest reduction.
Recommendation: In late spring of 1969, samples of aquatic insects in the test and control stream should be undertaken to determine the recovery of fish food organisms.

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.
