      The eastern spruce budworm (SBW) is the most damaging insect in Maine’s forest. Returning on a natural year cycle, the next outbreak is now at the state’s doorstep. The last SBW outbreak during the ss killed millions of acres of spruce-fir forest, cost the state’s.   In , western spruce budworm activity was highly apparent in Douglas-fir and grand fir forests of the eastern slope of the Cascade Mountains north of I and across parts of northeastern Washington. Many people noticed defoliated branch tips and tree tops for the first time as an ongoing outbreak spread to include their land or.

    Throughout most of its range, the Western Spruce Budworm completes one cycle of development from egg to adult within 12 months. Moths emerge from pupal cases usually in late July or early August; in the southern Rockies, adults often begin emerging in early July. Adults mate and within 7 to 10 days the female deposits her eggs and then dies. Management of spruce budworm, Choristoneura fumiferana (Clem.), outbreak spread requires understanding the demographic processes occurring in low, but rising populations. For the first time, detailed observations were made in the early stages of outbreak development. We sampled populations over a three-year period in both treated and untreated populations in the Lower St-Lawrence region of.

In Canada, new forestry practices involving the natural dynamics of tree growth and regeneration are proposed for integrating forest management with biodiversity. In particular, the current spruce budworm [Choristoneura fumiferana (Clemens)] outbreak in northeastern North America is forcing natural resource managers to clarify the potential interactions between natural disturbances and.

Effects of spruce budworm (Choristoneura fumiferana (Clem.)) outbreaks on the productivity and stability of forests in eastern Canada are reviewed and ation results in reduced growth of trees, widespread tree mortality, and loss of wood production, and thereby causes major forest management problems.

Abstract. Conifer-feeding budworms in the genus Choristoneura are eruptive species that periodically defoliate conifer forests in North America, causing growth loss and, ultimately, tree mortality.

These impacts create the need for management interventions. Emerging trends in forestry require a holistic approach that considers the implications of budworm management within an ecosystem context.

Spruce budworm (Choristoneura fumiferana) is a native insect that defoliates needleleaf trees, especially balsam fir (Abies balsamea) and spruces (Picea spp.), in northern North budworm can defoliate millions of hectares of forest during an infestation, depressing regional economies that depend on the timber industry.Impacts of Spruce Budworm and Forest Management on Future Wood Supply.

to simulate the coupled dynamics of different forest management scenarios and periodic budworm outbreaks across a million-acre study area in northern Maine to gain better understanding of how harvesting, salvage, and budworm outbreaks interact and influence forest.

The fact sheet is an assessment of the biology of spruce budworm in Minnesota and highlights tree symptoms and vulnerability of the native insect.

Forest management strategies, including thinning, are highlighted for managing and lessening the impacts of spruce budworm throughout the state. Interested readers can find the fact sheet here.
