Book Description
Excerpt from Insect Enemies of Eastern Forests In the publication on the western insects, emphasis is placed on bark beetle control, for in the western forests there still remain great reserves of overmature timber, which are subject to enormous bark beetle losses. Naturally, bark beetles and measures for suppressing their outbreaks are of overshadowing importance in those areas. In the eastern part of the United States, where there are practically no reserves of mature timber, the forester has before him the matter of growing new forests. Here, the forest-insect problem is principally the prevention of outbreaks. Therefore in this volume considerable emphasis is placed on the possibilities of so adjusting silvicultural practices as to avoid losses, as well as on direct control. Also, in the eastern forests there exists a preponderance of deciduous or hard wood species, which are more subject to attack by insects during log ging and manufacturing operations, and even after being placed in use, than are the conifers. The protection of logs, lumber, and crude and finished forest products is consequently a more important. Phase of forest entomology in the East.
