ABSTRACT.Terrestrial invertebrates are raised for producing biomass rich in animal protein, that could be used for feed or food products. A new method proposed here involves the non-stop use of invertebrates occurring in Siberia raised on cellulose-rich feed substrates to be developed under conditions of small or medium farms. Two saproxylic beetle species, green rose chafer Cetonia aurata viridiventris Reitter, 1896 and the European rhinoceros beetle Oryctes nasicornis (Linnaeus, 1758) are proposed as model species for this study. Biochemical analysis of model species larvae showed a high content of nutrients and reduced calorific value in the respective biomasses of Cetonia aurata and Oryctes nasicornis, namely 20.8 and 25.9% protein, 0.44 and 0.14% fat, 0.27 and 0.23% carbohydrates and calorific values of 99 and 96 kcal. Diverse contents of vitamins and minerals are also found, with the highest content of Mg 288 mg/100 g in Cetonia aurata and 251 mg/100 g in Oryctes nasicornis, and P 450 mg/100 g in Cetonia aurata and 400 mg/100 g in Oryctes nasicornis. Principles of feed substrate preparation, synchronization of beetle life cycles, and technological requirements for raising beetles on a farm are discussed. The duration of the life cycle decreased from 2 years in natural habitats to 7 months under laboratory conditions.
