Book Description
"Poplars, aspens and cottonwoods, which are widely distributed over the United States are everywhere subject to serious injury by wood-boring insects. One of the chief of these is the aspen borer, which feeds in the trunks or larger branches, so weakening the wood that the tree is readly broke off by windstorms. Plantations for paper pulp are often completely destroyed. This bulletin give methods of controlling the aspen borer or reducing its damage to a minimum. It is based on extensive studies made in the Pike Peak region of Colorado, but the data in general apply to all regions of the United States where the poplars are native. The introduced Lombardy poplar is very seldom injured, but the commercial cottonwood of the Mississippi Valley seems to be the only native species of poplar which is at all immune to the attack of this index."--Page [2].
