Development of a technological scheme of trichogram production on the basis of cassetteless breeding of grain moth

Abstract

Purpose. Elements of the equipment set will be created using the method of cassetteless breeding of grain moth for the industrial production of trichogram. This method involves carrying out a cycle of technological operations (infection, maintenance, exit and collection of imago) in one device, which allows to reduce the number of technological operations, labor costs, and dust generation. Thus, the cultivation of grain moth in a large volume makes it possible to abandon the traditional cassette-box technology and move to the construction of entomological production of a new generation. Methods. Research will be conducted using methodological approaches that are used in international practice, in particular, to meet the requirements of ISO 17025. The calculation of the mass balance and the technological scheme of trichogram production on the basis of cassetteless breeding of grain moth should ensure the reduction of operational costs for the implementation of technological processes of obtaining trichogram with guaranteed biological quality. Constructive decisions that will be made when creating a research and industrial model must be based on the principles of unification and resource conservation and meet sanitary, hygienic and environmental requirements. The production of elements of a set of equipment should be based on the use of materials and technologies that would ensure reliability, durability, reasonable cost of products. Results. Design documentation has been developed for a set of industrial equipment for the production of trichogram, which is characterized by the use of the method of growing grain moth in a large volume and the principle of optimizing technobiocenosis parameters in accordance with the biological and ecological needs of the “host” of the trichogram. Scientific and practical recommendations on the organization of trichogram production for biolaboratories have been formed. Samples of elements of the set of industrial equipment were produced and an approval certificate was drawn up. Tests of trichogram production equipment were carried out. The elements of the set of industrial equipment have been refined. Conclusions. The developed technological scheme and the calculation of the mass balance of the industrial production of trichogram based on cassetteless breeding of grain moth will provide an opportunity to increase the productivity of biolaboratories by 10–15 %, while obtaining a trichogram of guaranteed biological quality. An increase in the number of automated and mechanized technological operations is ensured by up to 20 %, a decrease in the metal content of the created grain moth and trichogram breeding equipment by up to 15 % compared to the existing one.
