CERTAIN FEATURES of the seasonal history and habits of the insect species which breed in severely weakened and dead balsam fir trees in the Lake Nipigon region of Ontario have been dealt with in a previous contribution (3). For many years it has been recognized that some of these insects attack weakened trees before death is obvious, and therefore possibly contribute to tree mortality. Various interpretations of the importance of these insects in the death of the tree have been reached by…

Balsam Fir (Abies balsamea (L.) Mill.) Wood Quality after Defoliation by Spruce Budworm (Choristoneura fumiferana Clem.) in the Boreal Forest of Quebec, Canada

Eastern spruce budworm (Choristoneura fumiferana Clem.) is considered the most important disturbing insect in coniferous stands in eastern North America. During an outbreak, spruce budworm can cause

Changes in the Forest Composition in the Great Lakes St. Lawrence Forest Region of Ontario and the Resultant Outbreaks of the Spruce Budworm Choristoneura fumiferana (CLEM.)

The spruce budworm Choristoneura fumiferana Clem, is the foremost forest pest in Canada. The species is endemic to eastern North America. Since the turn of the century the insect has become a major

Insect-host relationships influencing disturbance by the spruce budworm in a boreal mixedwood forest

Demographic data from a 15-year outbreak of the spruce budworm, Choristoneura fumiferana (Clem.) in a boreal mixedwood forest in Ontario, Canada, are used to interpret stand-level ecological disturbance in terms of susceptibility and vulnerability (mortality) of balsam fir, white spruce, and black spruce.

The balsam bark weevil, Pissodes striatulus (Coleoptera: Curculionidae): life history and occurrence in southern British Columbia

Subalpine fir (Abies lasiocarpa (Pinaceae)) forests in British Columbia (B.C.) are increasingly climate-stressed and vulnerable to pest damage. Following a drought in southern B.C., the balsam bark

Mortality patterns following spruce budworm infestation in unprotected spruce-fir forests in Maine

Red spruce was more vulnerable to budworm attack than balsam fir, and reached 92-100% basal area mortality and 84-97% stem density mortality 12 yr after the start of the outbreak.

In 1948, the Mississagi region of northern Ontario was swept by a niajor conflagration that began on May 25 and which, because of dry weather conditions, was not brought under control until July 23.

Tree-ring reconstruction of western spruce budworm outbreaks in the Rio Grande National Forest, Colorado

Tree-ring records were used to reconstruct the spatial and temporal patterns of western spruce budworm (Choristoneura occidentalis Freeman) outbreaks in the Rio Grande National Forest (RGNF) of

Sirex in Australasia

In their natural habitat, wood-wasps are secondary to other predisposing agents, which may include defoliation or debilitation of trees by insect and/or fungal attack,6,19 fire or smog damage,15,16 and mechanical injury.

Applying a Spruce Budworm Decision Support System to Maine: Projecting Spruce-Fir Volume Impacts under Alternative Management and Outbreak Scenarios

Spruce budworm (SBW) infestations and defoliation in forests of eastern North America (e.g., 1910s, 1940s, and 1970 –1980s) have had significant negative impacts on growth and survival of spruce and

Lumber and wood chips properties of dead and sound black spruce trees grown in the boreal forest of Canada

Little attention has been given to changes in wood properties after isolated mortality events, which characterize the gap dynamics of several forest ecosystems. For the forest industry, dead and

An intensive study of the death and deterioration of balsam fir was carried out from 1946 to 1951 in the area southwest of Lake Nipigon in northwestern Ontario, where a severe spruce budworm outbreak was in progress.

The work reported in the present paper is the result of one phase of a project planned to study in some detail the interrelations of certain insects and fungi attacking felled logs kept under more or less controlled conditions.
