This book was released on 2008 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the broad range of mitigation strategies associated with the management of mountain pine beetle (Dendroctonus ponderosae Hopkins), including methods that are currently utilized or proposed for controlling beetle populations, the manner in which the effectiveness of these approaches is monitored and assessed and, finally, the role that remotely sensed data may play in a large-area monitoring system. To this end, the authors first review the goals of effectiveness monitoring and introduce a general classification system to clarify the purpose and practice of efficacy monitoring. Based on these principles, the review is then structured around effectiveness evaluations for managing forest pests, primarily mountain, southern, and western pine beetles throughout North America. These evaluations are grouped by management strategy: silvicultural treatments; prescribed burns; and the use of attractants, repellants, and insecticides. Finally, the authors propose the use of remotely sensed data as a complementary tool for monitoring changes in the extent and severity of mountain pine beetle damage across large areas.--Document.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains 20 chapters about the impact, environmental fate, modes of action, efficacy, and non-target effects of insecticides. The chapters are divided into 7 parts. Part 1 covers the non-target effects of insecticides, whereas part 2 is dedicated to integrated methods for pest control, in which insecticides are an important element for diminishing the populations of insect pests. Part 3 includes chapters about the non-chemical alternatives to insecticides, such as metabolic stress and plant extracts. Insecticides and human health are the main topic of part 4, and the interactions between insecticides and environment are discussed in part 5. Part 6 includes the chapters about insecticides against pests of urban areas, forests and farm animals, whereas biotechnology and other advances in pest control are discussed in part 7.

This book was released on 1985 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mountain pine beetle (Dendroctonus ponderosae Hopkins) is the most destructive insect that attacks lodgepole pine (Pinus contorta Dougl.), a species valued for multiple uses throughtout North America. The effective residual life of carbaryl, applied as a 2 percent suspension of Sevimol to the bark of lodgepole pine to prevent attack by mountain pine beetle, was evaluated near Dillon, Colorado. Trees (9,568) treated in 1982 under operational conditions were used to assess the efficacy of the treatment for one and two beetle flight periods after insecticide application. Estimated mortality of untreated trees was 0.91 percent compared with 0.074 percent for trees treated 16 months earlier with carbaryl. Residues of carbaryl were estimated at 359 ppm 16 months after application. When exposed to intense beetle pressure, bolts from trees treated 13 months earlier suffered fewer attacks and had shorter mean egg gallery length than did bolts from untreated trees; bolts from trees sprayed 3 months earlier suffered no attacks. Apparently a 2 percent suspension of carbaryl applied to the bole of lodgepole pine was effective in protecting lodgepole pine from mountain pine beetle for the flight period 3 months after application and even provided protection for a second flight period 16 months after treatment. I The results suggest that protection cost and I insecticide use could be reduced by 50 percent during a 4-year outbreak.
