A Guide to the Insect Borers, Pruners, and Girdlers of Pecan and Hickory Pecan and ten species of hickory are native to the Eastern United States. Most of these trees are economically important in timber production, commercial nut production, or as ornamentals, and serve as an important food for wildlife. Although a number of insects, including borers, pruners, and girdlers, are injurious to pecan and hickory and are widely distributed, they seldom threaten trees over large areas. Damage tends to be local, in nurseries, nut-producing groves, young timber plantations, and ornamental plantings. Damage includes a loss of tree form; reduced nut crops; defects in wood that reduce its value for lumber, veneer, and other products; loss of esthetic beauty of 38 shade and ornamental trees; destruction of grafts; and, sometimes, death. Damage can be minimized by good management, especially through cultural practices that maintain and promote tree health. "A Guide to the Insect Borers, Pruners, and Girdlers of Pecan and Hickory" should be of interest to a wide audience, including forest managers, nut growers, entomologists, extension agents, pest-control specialists, educators, and homeowners. This publication explains how to identify the insects that attack shoots, branches, trunks, and roots of pecan and hickory, and how to prevent or reduce the damage they The gallery of a hickory borer, in a cross section of Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States.
