Control of Cone Insects in Southern Pine

In years past, insect damage to tree seed in the South has been considered of relatively minor importance to the forester and entomologist alike. It was and still is largely taken for granted that there are good seed years and poor seed years, depending upon the whims of the individual tree species --dovetailed in with a variety of other ecological or climatalogical factors. The purpose of this brief paper is to illustrate that lacking the ability to do much about the cyclic habit of good seed years, we can, with the expense of some time, tender, and, no doubt, trouble make every seed year a better seed year than normally would be the case.
