Book Description

Excerpt from An Annotated List of the Important North American Forest Insects Little in the way of investigation of insects affecting shade and ornamental trees and hardy shrubs Is done at the present time, and most of the effort in this work is expended in service. There is a great and increasing demand from municipal authorities, estate owners and managers, small property owners, tree surgeons, and nurserymen for advice on methods of handling their entomological problems. The division of forest insects attempts to meet this demand by correspondence, publications, and occasional surveys and studies. Whenever possible, observations are made on important species and, where practical, experiments in methods of control and improvements in such methods are conducted.
