This book was released on 2006 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2000 and 2002, Verbenone, a compound with anti-aggregation properties for mountain pine beetle, Dendroctonus ponderosae, was tested for reducing attacks by the insect in Ponderosa pine, Pinus ponderosae forests. The verbenone was released to the environment with the use of permeable membranes; the first year with plastic capsules (containing 0.8 g of verbenone) and the second year with an envelope-like pouch (containing 5.0 g of verbenone). The plastic capsules were deployed at a rate of 25 and 64 capsules per acre and a no capsule treatment served as control. The pouches were deployed at 30 and 50 pouches per acre and a no pouch treatment was the control. Mountain pine beetle attractants were placed on three trees at plot center to ensure insect population pressure. In neither experiment were there any observed differences in (1) number of mountain pine beetle-killed trees, (2) number of partial attacks (strip attacks), (3) number of unsuccessful attacks (pitch-outs), (4) diameter at breast height of infested trees, (5) attack height of infested trees, (6) mean distances of infested trees to verbenone releasers, (7) attractants located at plot center. The possible influence of stand environment is discussed as reason for lack of effectiveness. At this point, based on this and prior studies the operational use of verbenone for reducing mountain pine beetle-attacked trees in ponderosa pine forests is not advisable. Further studies on this topic should be conducted in the future as treatment technology is developed further or the appropriate release amount and timing is better understood.

Available in PDF, EPUB and Kindle. Book excerpt: Insects are the most abundant and diverse organisms that inhabit our planet and are found in all the world’s forest ecosystems. Many feed and/or breed on parts of trees. Some perform important functions, such as pollination or break-down of dead vegetation. Others weaken, deform or kill trees, and compete with humans for the many goods and services that trees and forests provide. Forest Entomology: A Global Perspective examines forest insects in a global context and reviews their dynamics, interactions with humans and methods for monitoring and management of species that damage forests. Also provided are 235 profiles of forest insects, worldwide. A series of tables provides summaries of the distribution and hosts of many more species. Included are those that damage forests, others that are simply curiosities and some that are beneficial. This book is designed as a reference for students, practicing foresters and forest health specialists, especially for those who work internationally or are concerned with species that have the potential to expand their ranges via international trade, travel or environmental changes.
