Download or read book Insects of Eastern Pines written by Arthur H. Rose and published by Miscellaneous Report / Geologi. This book was released on 1999 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook is designed to enable people who are interested in trees to identify the insects and mites causing damage to them. About 90 species of insects and mites that have caused noteworthy damage to pines in Canada east of the Rocky Mountains are included. The insect and/or its damage can be identified by means of flow chart keys, and the identity of the insect or mite can be confirmed by reference to about 190 colour illustrations. The accompanying biological sketch for each insect or mite usually includes information, based largely on Fores Insect and Disease Survey records, on necessity for control. Where control is necessary, methods are suggested. Common names of insects are generally used, but scientific names are also given in the text.

Download or read book Pine Wilt Disease written by Bo Guang Zhao and published by Springer Science & Business Media. This book was released on 2008-09-27 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pine forests face a global threat of pine wilt disease, which is being spread by vector beetles carrying pathogenic nematodes from dead trees to healthy ones. Among the host pines there are varying degrees of susceptibility, and nematode strains also contain a variety of virulences, both of which factors help to determine whether infected host trees will die or survive. As well, biotic and abiotic environmental factors influence the fate of infected trees. This book describes the history of the disease, pathogenic nematodes, vector beetles, the etiology and ecology of the disease, microorganisms involved, and control methods that utilize host resistance and biological control agents. Concrete, comprehensive, and the most up-to-date knowledge about this worldwide forest epidemic is presented for readers, enabling them to understand the nature and epidemic threat of pine wilt disease.

Book excerpt: "This book presents a synthesis of published information on mountain pine beetle (Dendroctonus ponderosae Hopkins [Coleoptera: Scolytidae]) biology and management with an emphasis on lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) forests of western Canada. Intended as a reference for researchers as well as forest managers, the book covers three main subject areas: mountain pine beetle biology, management, and socioeconomic concerns. The chapters on biology cover taxonomy, life history and habits, distribution, insect-host tree interactions, development and survival, epidemiology, and outbreak history. The management section covers management strategy, survey and detection, proactive and preventive management, and decision support tools. The chapters on socioeconomic aspects include an economic examination of management programs and the utilization of post-beetle salvage timber in solid wood, panelboard, pulp and paper products."--Publisher's description.

To make the information contained in this volume more easily accessible, insects are grouped according to the tree species that they attack rather than by their entomological classification, and, for this reason, insects found on a given tree species are presented in the same chapter. The annual reports of the Forest Insect and Disease Survey have provided most of the information on history of outbreaks that is found in the text.
