Knowledge of Seed-Orchard Pests Scanty

I have been invited to speak to you today about insect problems associated with the establishment and management of southern pine seed orchards. Research is constantly developing improved methods of culturing and managing forests. Such advances frequently provoke a reaction by insects. Insects are always present, but many remain harmless until a change in the environment favors their increase. New developments in the seed orchard program furnish an example. The crowns of trees from which cuttings are taken typically are infested by insects such as tip moth, gall weevil, pitch moth, midges, and small twig-borers known as Pityophthorus beetles. Most of these insects have little effect on forest trees and pass unnoticed upon the foliage. But when infested scions are grafted to the rootstock of potted seedlings, these same insects suddenly assume a prominent role by destroying the stem and terminal bud of valuable grafts.
