Utilization of Budworm Killed Spruce and Fir in Full Scale Sulfite Processing

Problem Addressed: Production of fully bleached market sulfite pulp and spruce budworm's effect on it.
Goal(s)/Objective(s): Outline some of the wood utilization techniques now in place and discuss the effect of budworm killed wood on product quality.
Key Findings: The increasing consumption of budworm killed wood at Nova Scotia Forest Industries shows no deleterious effect on pulp strength properties for bleached sulfite market pulp.

Susceptibility of Balsam Fir to Spruce Budworm Defoliation as Affected by Thinning

Problem Addressed: Spruce budworm defoliation of balsam fir.
Goal(s)/Objective(s): Quantify defoliation levels in treated and control plots in order to determine what effect, if any, thinning had on the susceptibility of balsam fir.
Key Findings: Susceptibility of balsam fir to spruce budworm defoliation was not affected after thinning in coniferous and hardwood forest types.

Spruce Budworm Management Planning — Limiting Environmental Impacts

Problem Addressed: Environmental impacts from forest management and processes.
Goal(s)/Objective(s): Give an appreciation of the types of environmental impacts that are associated with spruce budworm management and to demonstrate that pests can be managed in several ways, each with different impacts.
Key Findings: Environmental impacts depend on not only management strategy and insecticide but also on application rate, formulation, spray timing and block layout.

Sticky-Board Trap for Measuring Dispersal of Spruce Budworm Larvae

Problem Addressed: Spread of spruce budworm larvae.
Goal(s)/Objective(s): Describe a new sticky-board traps for measuring early-larval dispersal of the spruce budworm, Choristoneura fumiferana (Clem.), and evaluates trap-board color and screen versus unscreened traps.
Key Findings: Dispersing spruce budworm larvae showed no preference for trap color; fewer nontarget arthropods were caught ondark-colored than on light-colored traps. Screened traps caught significantly more spruce budworm larvae than unscreened traps, and they were easier to examine.
