 abstract={The purpose of this study was to examine variations in numbers and vertical distribution of a population of Phyllaphis fagi L. in the undergrowth and crowns of the beech (Fagus silvatica L.). In addition an attempt was made at ascertaining the ecological factors affecting uneven development of different generations of aphids. Observations show that aphids develop best in the top layers of tree-crowns in spring, but in the lower layers in autumn, and in summer in the upper layers of the undergrowth. The numbers of aphids depended on the combined action of food, temperature and humidity conditions.},
