Analysis of existing technologies for mass rearing and use of beneficial insects and mites has shown that for effectiveness improvement of protective measures and for volume increasing of biological agents it is necessary to develop new and improve existing methods and procedures of mechanization of these processes. On based of results, obtained and characteristics of investigation of insects and mites rearing on different substrates and plants, physical and mechanical properties of biological material as a working environment, have been designed and manufactured of experimental equipment. The technical means elaborated alone mechanization of most labor-intensive processes of mass rearing and providing possibility for effectiveness of production and application biological agents in plant protection.
