Abstract

In many countries there were established viral preparations applied in practice in order to reduce the number of pests. Report contains the results of application viral preparation and biotechnological processes for the production of biological preparation Virin-ABB-3 for protection of agricultural, ornamental and forest crops of Hyphantria cunea Drury in labora-tory and field conditions. The preparation is based on viruses of nuclear polyhedrosesis and granuloses with cumulative and synergetic action. One important element in the technological process of biological preparations is to develop techniques for increasing the mass of larvae of pests in continuous series, which gives the viral biological material all round year.
