CFRU to Host Spruce Budworm Webinar

CFRU Webinar Series Spruce Budworm: Monitoring and Early Intervention Strategies February 14, 2018, 2:00 p.m. EST The first webinar in our new CFRU series will focus on spruce budworm monitoring and early intervention strategies. Following an update on spruce budworm conditions in Maine by Allison Kanoti, Rob Johns will speak to us about the New Brunswick's monitoring, early intervention, and communication strategies employed to combat spruce budworm in the province. There will be time ... Read More ›

Spruce Budworm Trap Retrieval in Maine Reveal Budworm Moth Catch

This month professional foresters around the state are working with USFS and CFRU research scientists to retrieve spruce budworm traps that were hung in designated areas in the north Maine woods over the summer. The trap catches will be analyzed to assess spruce budworm populations in the state. And yes, there are some SBW moths in those traps (see photo). In addition, researchers are collecting branch samples for the 2017 L2 data analysis. For more on the L2 data, see Maine Spruce ... Read More ›

What’s happening with New Brunswick’s Forest Pest Management Team this Season

The spring and summer are busy months for the Forest Pest Management Team at New Brunswick's Department of Energy and Resource Development (ERD).  From the day that seasonal staff arrives in June they get to work setting SBW pheromone traps throughout the province. These traps are used as early warning signs of population growth and you can read more about them in one of our previous blog posts. After the pheromone traps are hung, our staff switches focus to two vital components of the EIS ... Read More ›

To the north, spruce budworm treatment concludes and research begins

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.

Early Intervention Progress in New Brunswick

New Brunswick's early intervention efforts to prevent SBW spread is in full swing. To date, 80% of the project's total area (150,000 ha) has been treated. For more information on the early intervention strategy, visit the Healthy Forest Partnership website. ... Read More ›

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 ›
