DescriptionA serious outbreak of the pine sawfly, Neodiprion pratti pratti (Dyar), now extends over a gross area of more than 14 million acres in Maryland, Virginia, and North Carolina. Since 1955, the approximate extent and severity of infestation have been determined from aerial and ground surveys by the U. S. Forest Service and state personnel. Indications are that the outbreak will continue in 1960.
