Problems of influencing insect populations by changing the food quality . In forest entomology, as opposed to plant and livestock breeding it is not possible at the present stage to make use of changes in food quality as a routine technique for influencing insect populations. Although noticeable reactions of insects to changes in food quality have been known for a long time research on this matter has not yet reached a stage far beyond a first tentative screening. A careful elaboration of these questions is suggested to master the forthcoming problems like the cultures of clones of spruce trees or fertilizing of forest trees.
