Extract

This paper describes the seasonal history and habits of three borers of the genus Dioryctria that destroy red pine cones in Ontario. These insects, as a group, generally rank second in importance as cone destroyers to the cone beetle, Conophthorus resinosae Hopk., which was the subject of the first paper in this series (11), and are presented together because of their family relationship and the similarity of their habits.
