Infested Northern Red Oak (Quercus rubra) trees were felled and cut into 0.5m sections. Whole trees and systematically selected sections of trees were examined and dissected in the laboratory. Red oak borer entrance and exit holes on the bark surface were recorded and mapped using a coordinate system. The bark was removed from each section and early and late larval galleries were mapped using the same methods. Two-dimensional maps were developed which depict red oak borer populations at various life stages. Mapped data were divided into four quadrants, each centered on a cardinal direction. Preliminary results indicate no statistical difference between the number of entrance holes in each quadrant while late larval galleries appeared to be non-randomly distributed around the bole.
