Book excerpt: Excerpt from The Pandora Moth, a Periodic Pest of Western Pine Forests Under normal conditions infestations of this moth are of no eco nomic consequence because no appreciable injury is done to the tree. Epidemic infestations by this moth are, however, a serious menace to pine stands. The damage resulting from such infestations divides itself into two phases: The primary injury to the tree, which results directly from the loss of needles, and the secondary injury through the impaired vitality of the tree, which renders it susceptible to bark beetle attack.

Book excerpt: This field handbook has been prepared to provide information on western forest insects. The discussions are limited to the insects and the problems which they raise in the management and protection of the forests of the Western States, although the general principles of control are applicable to other forest regions as well. It is hoped that the information assembled will add timber owners and foresters in recognizing the work of important western forest insects, in applying suitable control measures, or in adjusting forest practices so as to reduce losses from this source to the lowest possible point.
