Canada's boreal forest is a vast region comprising about one third of the circumpolar boreal forest that rings the Northern Hemisphere, mostly north of the 50th parallel. Other countries with boreal forest include Russia, which contains the majority, the United States in its northernmost state of Alaska, and the Scandinavian or Northern European countries (e.g. Sweden, Finland, Norway . Spruce Budworm. Scientific name: Choristoneura fumiferana Phenology models predict timing of events in an organism's development. For many organisms which cannot internally regulate their own temperature, development is dependent on temperatures to .

The eastern spruce budworm (Choristoneura fumiferana) is one of the most destructive forest pests in North America. It is a native moth in the Tortricidae family, belonging to the budworms species complex. Its larvae feed on the buds and young leaves of conifers, bringing about massive losses in wood production and harvesting. It belongs in a.

Western spruce budworm is the most widely distributed forest defoliator in western North America. Budworms have a one-year life cycle and are actually a small moth at full maturity. Here in the West, there can be severe infestations in healthy Douglas-fir, white fir and spruce. Sippell, W.

Outbreak dynamics of the spruce budworm, Choristoneura fumiferana, are predicted to change, move further north, and on to secondary host species [17, 18]. Similarly, cyclical outbreaks of. This finding contrasts with results from shorter time—scale studies conducted in northwestern U.S.
and Canada (western spruce budworm) and eastern Canada (spruce budworm C. fumiferana), where low precipitation and/or warmer temperatures were generally associated with outbreaks. Different patterns of budworm population response to changing. 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. The spruce budworm, Choristoneura fumiferana (Clemens), (Lepidoptera: Tortricidae) was first described from specimens collected in Virginia, 17 but this native insect occurs primarily in the northern boreal forest from Newfoundland west to the McKenzie River near 66°N.
53 The most extensive and destructive outbreaks have occurred in the maritime provinces (New. Spruce budworm (Choristoneura fumiferana (Clemens)) (SBW) outbreaks are a major disturbance that influence stand dynamics and succession in balsam fir (Abies balsamea (L.)

Columbia and Alberta, Canada (fig. The first recorded western spruce budworm outbreak was in on the southeastern part of Vancouver Island in British Columbia, Canada.
Since that year, infestations of this and related spe-cies frequently have been reported in western Canada. The budworm was first reported in the United States in in. Economic impacts of forest pests: a case study of spruce budworm outbreaks and control in New Brunswick, Canada.

e following report was prepared by: Task Force Leaders. The entire range of white spruce forests in North America is considered vulnerable to outbreaks of spruce budworm under projected climate change.
In the Northwest Territories of Canada, for example, the northern limit of current spruce budworm outbreaks is approximately kilometers south of the northern limit of its host, the white spruce. Western spruce budworm (WSBW) is a common defoliating insect that has caused extensive damage and mortality to a number of tree species across the western United States (US).
Past studies have linked outbreaks of WSBW to increased moisture stress of host trees in the Northwest and decreased moisture stress in the Southwest. Our study analyzed seasonal. Dorais, L. and E.G.

Contact Michigan DNR: Bob Heyd,ext. or John Pepin, Over the past few years, white spruce and balsam fir have been defoliated by the spruce budworm, one of the most destructive native insects in the northern spruce and fir forests of the eastern United States and Canada.
The spruce budworm, Choristoneura fumiferana (Clem.) (Lepidoptera: Tor tricidae), is native to eastern Canada and does not occur elsewhere.
There has been knowledge of its behavior since We will first give the life cycle of a spruce budworm since we need to know at what stage(s) they will be affected by predators and/or insecticides. The. This type of process is evident in the analyses of spruce budworm dynamics in New Brunswick, Canada, where dispersal of budworm is implicated as an important element in determining local abundance (Royama, ).
However, the large distances between the studied budworm populations made direct evaluation of the importance of movement impossible.affected by spruce budworm outbreaks in eastern Canada (Gray & MacKinnon, ; Figure 1), and the species had been observed on at least three routes and in at least 4 years/route, averaged across the included routes.
Responses to spruce budworm defoliation were compared for eight warblers. These warblers included three species that have."CANUSA, Canada/United States Spruce Budworms Program"--Page 2. "February "--Page 2.
