Available in PDF, EPUB and Kindle. Book excerpt: Spruce budworm (Choristoneura fumiferana (Clem.)) outbreaks are a dominant natural disturbance in the forests of Canada and northeastern USA. Widespread, severe defoliation by this native insect results in large-scale mortality and growth reductions of spruce (Picea sp.) and balsam fir (Abies balsamea (L.) Mill.) forests, and largely determines future age–class structure and productivity. The last major spruce budworm outbreak defoliated over 58 million hectares in the 1970s–1980s, and caused 32–43 million m3/year of timber volume losses from 1978 to 1987, in Canada. Management to deal with spruce budworm outbreaks has emphasized forest protection, spraying registered insecticides to prevent defoliation and keep trees alive. Other tactics can include salvage harvesting, altering harvest schedules to remove the most susceptible stands, or reducing future susceptibility by planting or thinning. Chemical insecticides are no longer used, and protection strategies use biological insecticides Bacillus thuringiensis (B.t.) or tebufenozide, a specific insect growth regulator. Over the last five years, a $30 million research project has tested another possible management tactic, termed an ‘early intervention strategy’, aimed at area-wide management of spruce budworm populations. This includes intensive monitoring to detect ‘hot spots’ of rising budworm populations before defoliation occurs, targeted insecticide treatment to prevent spread, and detailed research into target and non-target insect effects. The objective of this Special Issue is to compile the most recent research on protection strategies against spruce budworm. A series of papers will describe results and prospects for the use of an early intervention strategy in spruce budworm and other insect management.

Marsden and published by Forgotten Books. This book was released on 2018-01-09 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Susceptibility of Stands to Defoliation by Western Spruce Budworm on the Payette National Forest, Idaho The forest inventory stand data consisted of a probability sampling of stands for a forest. Attributes of these stands can then be used to obtain unbiased estimates of that attribute for the total forest. The attribute can be a defoliation rating or a habitat type series, or the intersection of the two. For example, total acreage, which is in the grand fir habitat type series and is defoliated for more than five years, can be estimated.
