Book excerpt: Excerpt from Insect Enemies of Western Forests Published bulletins, articles, and records, unpublished reports by field men, and manuals of instruction have been used freely as needed. The text of earlier editions has been revised extensively, to take into account the new insecticides developed during World War II and the tremendous change such chemicals as ddt have made on forest-insect-control procedures. J. M. Miller, J. C. Even den, R. L. Furniss, and N. D. Wygant furnished material from the different regions of the West. 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. This manual is restricted to insects found in forests west of the Great Plains, roughly the 100th meridian. Insects of shade and ornamental trees are touched upon only incidentally. A companion volume, Insect Enemies of Eastern Forests, by F. C. Craighead and eastern workers (37) (miscellaneous Publication 657) should be consulted for information on eastern forest insects and many others that are Nation-wide in distribution.
