Alkali Solubility as an Indication of Decay in Diseased Wood

Problem Addressed: Spruce Budworm infestation

Goal(s)/Objective(s): Determine if, in fact, the 1% alkaline solubility test could serve as a valuable empirical measurement of decay in wood to be used in pulping and to obtain experimental data to be used in a future study of the effect of decay on pulp yield and strength properties (using 5/8" and 7/8" chips in pulping)

Key Findings: The 5/8" and 7/8" chip samples led to accurate and reproducible results. Since 5/8" and 7/8" chips are typically considered to be part of the accepted chips used in industrial pulping, the 1% NaOH solubility test could serve as a useful and reliable measurement of decay of wood to be used in industry.

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.

Biological Impact Studies of Experimental and Operational Spruce Budworm (Chloristoneura fumiferana Clemens) Control Programs on Selected Non-Target Organisms in Quebec, 1976

Goal(s)/Objective(s): Presents the findings of impact studies carried out in areas treated with the organophosphorus insecticides fenitrothion, phospohorothioate and phosphamidon in the Mont Tremblant, La Tuque and Chandler areas of Quebec, and the results of investigations into reports of accidental damage to the environment resulting from budworm control programs.

The Epidemiology of the Current Spruce Budworm Outbreak in Quebec

Problem Addressed: Spruce Budworm in Quebec

Key Findings: 1. Make early detection and intervention possible because of the fact that epicenters are restricted to a small portion of the range, thus presenting the possibility of using pheromone traps in small areas to monitor population changes and eventually of exerting control of the epicenters and curtailing the spread of the outbreak. 2. Limit aerial spraying to the zone of occasional abundance and parts of the zone of normal abundance where the duration of the outbreak and the ensuing damage warrant such expenditures.
