Aerial Photographic Techniques for Assessing the Impact of Spruce Budworm Defoliation in Maine

Goal(s)/Objective(s): Development of remote sensing techniques to better evaluate current feeding, tree and forest condition from past feeding, forest recovery after spraying, and mortality location from spruce budworm defoliation and other causes.
Key Findings: Tree and forest stand condition from past feeding was best interpreted on the CIR fall photos at scales of 1320 ft/in and larger

Debarking Wood Losses and Chip Quality of Deadwood

Problem Addressed: Losses of commercially valuatble softwood timber, particularly of white spruce and balsam fir
Goal(s)/Objective(s): Evaluate losses of softwoods due to spruce budworm as a function of the time since death

Detecting Forest Insect Pests in Canada

Goal(s)/Objective(s): Review McGugan's paper briefly, to describe the present capability of detecting forest insect pests in Canada, and finally, to offer a few comments about the future
Key Findings: If we possess enough knowledge about the systems involved and can monitor or measure the appropriate parameters, it might be possible to predict when and where outbreaks will occur.

Determination of Fenitrothion Residues in Honeybees and Their Products

Goal(s)/Objective(s): Describe the development of a gas-liquid chromatographic (GLC) method of analysis of the parent insecticide, its oxon and the cresol hydolysis product in honeybees (Apis mellifera L.) pollen, beeswax and honey from forested areas which had been treated with fenitrothion applied by aircraft.
Key Findings: Average recovery for the insecticide ranged from 84% in bees to 93% in honey.

Evaluation of Spruce Budworm Feeding Damage and Spray Success Using Remote Sensing

Problem Addressed: The evaluation of spray success using color and color infrared aerial photography
Goal(s)/Objective(s): Determine the location and amount of mortality caused by the spruce budworm, detect areas of new budworm attack earlier than with present models, identify forests requiring spraying or other control measures to prevent excessive tree mortality and timber loss from budworm attack more efficiently than with present methodology.

A History of the Effects of Aerial Forest Spraying in Canada on Aquatic Fauna

Problem Addressed: Pesticide spraying
Key Findings: Much progress has been made in discovering and eliminating undesirable side-effects of forest insect control operation in Canada on aquatic ecosystems, however, the role of many factors related to insecticide toxicity and side-effects still remain vague.
