Excerpt from The Identification of Primary Red Pine Cone Insects Red pine (pinus resinosa Ait.) is one of the most important species used for reforestation in the Lake States.

This guide will familiarize the forester or nurseryman in the Lake States with the damage caused by insects to red pine cones, and enable him to recognize the mature larvae of the various spe cies and understand their relative importance.
