Abstract

An outbreak of the pine sawfly, Neodiprion pratti pratti (Dyar), has existed in Maryland since 1955. By 1959 the insect had spread throughout 14 million acres in the Coastal Plain and Piedmont of Virginia and into several North Carolina counties. Because egg surveys conducted in the spring of 1960 indicated a continuation of the epidemic, an aerial survey was conducted to further evaluate the situation. This report contains a summary of this latter investigation.
