In fact, the entire technical force of the Bureau's western forest-insect laboratories con tributed material for this publication. J. E. Patterson assisted in preparing the illustrations.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Some Insects Injurious to Forests: The Western Pine-Destroying Barkbeetle The object of this paper is to give available information on. This insect and methods of combating it, with special reference to the results of investigations by the writer during the summer of 1905 in central Idaho. The need of the investigations was suggested in a letter dated August 10, 1904, from Mr. Gifford Pinchot, forester of the U. S. Department of Agriculture, to Dr. L. 0. Howard, chief of the Bureau of Entomology, as follows: I learn from the Payette Lumber and Manufacturing Company, one of the Weyerhaeusers, whose land lies on the Payette River north of Boise, that the pine in their holdings is said to be dying from the attacks of insects. If it were possible for you to assign Doctor Hopkins, or one of his assistants, to make examination of this region, unless it has already been done, I should greatly appreciate it, and I should likewise appreciate your sending to Mr. Edgar M. Hoover, general manager of that company at Boise, any information you may have bearing on this subject. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Insect Enemies of California Pines and Their Control Classic Reprint written by F. P. Keen and published by Forgotten Books. This book was released on 2017-10-29 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Insect Enemies of California Pines and Their Control While much of the information contained in this circular has been previously published in a number of miscellaneous government bulletins, state bulletins, entomological journals and textbooks, most of these are either out of print or are not easily obtained by the interested timber owner. In addition, a great deal of new material, including unpublished notes of the author and other forest entomological workers, has been included, in order to bring the information up to date and give the timber owners and foresters the benefit of results obtained in recent investigations and control experiments. The descriptions of the insects and their work are grouped, as far as possible, according to the natural relationships of the insects, while the groups themselves are arranged in order of their importance in the forest. The host lists and keys to the work enable the forester to find any particular insect from the standpoint of the tree and part of the tree affected. Natural-sized photographs have been used wherever possible, as it was felt that these would be of the most assistance to the layman in recognizing the destructive species. In order to do this it was necessary, in nearly every case, to take original photographs. Published pictures or those furnished by other workers have been acknowledged in the text.
