Using of entomoptogenic baculovirus pesticides for biological controls of pest insects in the republic of moldova

In many countries in recent years, to use natural entomopathogenic pesticides to control the number of pests. Potential agricultural production loss caused by the activity of pest organisms in the world was always a concern at international level. In many countries were established baculoviral preparations applied in practice in order to reduce the number of pests. In such context, the problem is connected to large application of baculoviral preparations that have become a reality only by elaboration and organization of production of such biological means, work registered after execution of deep biotechnological researches. 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. Materials. For determination of concentration of baculoviral suspensions there were used different methods, especially electronic microscope. The isolation, detection and determination of the biological features of baculovirus isolates were carried out in accordance with generally accepted methods. Results. 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. The criterion of stable ecological system and the methods restoration and construction were also analyzed. Testing of the preparation Virin-ABB-3 for control development, II generation, on plants has demonstrated a significant biological efficacy of 91,52% in comparison with that of chemical etalon Lepedocid 100 %. 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.
