Baculoviruses have shown to be a good tool for insect pest control. Numerous natural baculoviruses have been used as biopesticides worldwide as they are naturally occurring pathogens, highly specific with limited host range, and without lethal effects on non-target organisms. The aim of the present paper is to discuss the results of two years attempt of biological control of H. cunea populations with a baculoviral product. In the report there are also submitted the results of the joint application of the biological preparation Virin ABB-3. The preparation is based on viruses of nuclear polyhedrosesis and granuoses with cumulative and synergetic action. In such context, the problem is connected to large application of baculoviral preparation that have become a reality only by elaboration and organization of production of such biological means, work registered after execution of deep biotechnological researches. Meanwhile, the experiment in which viruses were used and successfully control of the species H.cunea persistently indicate that the insect viruses play an important role in restoring and constructing stable natural and antropinated ecology system.
