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 In addition, a great deal of new material, including unpublished notes of the author and other forest entomological workers, has been included, in order to bring the information up to date and give the timber owners and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.
