In New Brunswick, another year of experimental treatments for the Early Intervention Strategy (EIS) have come to pass. The 2017 treatments began on June 13th, when the spruce budworm larvae were entering their mid instar developmental stage. This timing is important as the insecticides we use must be eaten by the larvae to have an affect. This year our experimental treatment area covered 150 000 ha.

New Research on Spruce Budworm
New from the Canadian Journal of Forest Research: Bottom-up factors contribute to large-scale synchrony in spruce budworm populations by Mathieu Bouchard, Jacques Regniere, & Pierre Therrien Understanding the mechanisms that cause large-scale synchrony in insect population dynamics might yield key insights for predicting potential outbreak occurrence. Here, we evaluated which environmental factors best explain synchronous population fluctuations in the spruce budworm (SBW). SBW population ... Read More ›
Balsam Fir Stand Development Post SBW-related Mortality
University of New Brunswick researchers Grant Virgin and Dave MacLean's article, Five Decades of Balsam Fir Stand Development After Spruce Budworm-related Mortality, has just been published online in Forest Ecology and Management. Highlights Five decades of stand development in spruce budworm affected plots in New Brunswick. Stand development and self-thinning patterns varied based on post-outbreak stocking. Thinned and unthinned plots had more volume at younger ages than budworm ... Read More ›
