Excerpt from Flat-Headed Borers Affecting Forest Trees in the United StatesFlat-headed borers (buprestid larvae) are among the most important of the borers infesting forest trees in the United States. Some mine the leaves, one burrows into the cones, a number bore into the inner bark and. Outer wood of the trunk, branches, and roots, while the majority excavate oval winding wormholes throughout the sound or decaying sapwood and heartwood.At present the leaf-miners and the cone-burrower are not common enough to be important. The bark-borers often girdle and kill healthy trees or those injured by fire, ¿oods, droughts, diseases, other insects.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
