The aim of the work is to study and substantiate the design of the installation for realization of the technology of cassette-free breeding of the grain moth (Sitotroga cerealella). This installation assumes the realization of the cycle of technological operations (infestation, maintenance, output and collection of adults) in one apparatus. This allows to reduce the number of technological operations, labor costs, metal intensity and production area. Cultivation of grain moths in a large volume makes it possible to abandon the traditional cassette-box technology and move to the construction of new generation entomological production facilities. The developed unit for the production of grain moths is recommended for use in the implementation of biotechnological processes in accordance with the created technological scheme of industrial production of trichogramma. The proposed installation allows to create industrial production equipment. Technical characteristics of the developed installation are formed. Its practical value consists in the fact that in comparison with the traditional cassette-box method of breeding the improvement of grain population by 4%, number of females by 5%, fertility of eggs by 2% was achieved.
