The paper presents the results on technology of cultivation of apple-tree saplings and the ways to regulate the phytophage population. The nature of distribution of one of the main nursery pests such as woolly aphid and its specialized entomophage – aphelinus - has been studied. A woolly aphid - typical representative of sucking phytophages - is characterized as a dominant species in the gardens and nurseries of Ukraine and Kazakhstan. Standard methods of research were used in the course of work. Based on the studies, a set of factors forming the structure and dynamics of red woolly aphids in apple tree nurseries has been determined. The natural populations of parasites and predators play an essential role for its population dynamics. The principle possibility of regulating the population and protection of nurseries from woolly aphids using the method of settling the natural populations of the hymenopteran entomophage aphelinus has been established.
