Abstract
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.
Highlights
The problem of growth of the gross fruit crops in gardens is resolved primarily through intensification of production, where, in a set of factors, the crop protection from phytophages and phytopathogens is of great importance
The studies conducted give the basis to draw the conclusion that the woolly aphids are widespread in nurseries of Ukraine and Kazakhstan (Fig. 1)
As our studies have shown, natural populations of parasites, predators and, partly, entomopathogens play an important role in the dynamics of the number of woolly aphids
Summary
The problem of growth of the gross fruit crops in gardens is resolved primarily through intensification of production, where, in a set of factors, the crop protection from phytophages and phytopathogens is of great importance. Obtaining a quality fruit crops is a very topical problem. The solution to this problem is related to the rational use of the range of pesticides. Since the planting material grown has a wide geography of supplies within the country and sometimes is exported abroad, in the absence of phytosanitary control the nursery may become a source of propagation of parasites and phytopathogenic microorganisms. In this regard, the issues of phytosanitary and plant protection, monitoring of species that damage cultivated plants in nurseries, are very relevant
