Introduction. The population of planet Earth largely depends on agricultural production of plants and animals to meet the food demand. However, humans are not the only organisms that eagerly consume these products. Every year, insect pests cause serious damage to agriculture. Loss of productivity and the high cost of chemical pesticides increase the cost of production. Continuous use of chemical pesticides creates selective pressure, leading to the development of pest resistance. Excessive residues of chemical pesticides also pollute the environment, including soil and water. Therefore, biological control of insect pests in agriculture becomes more important due to food safety and environmental concerns. In this regard, bacterial insecticides offer a better alternative to chemical pesticides. This not only helps establish food security by combating insect pests but also ensures the safety of food products.

The aim of the study is to substantiate the conditions for the safe application of biological insecticidal preparations in agriculture.

Materials and methods of the study. Objects of study: Biological insecticidal preparation INSECTA BBM, LLC (active ingredients – Bacillus thuringiensis, not less than 1,0×109 CFU/g, Metarhizium anisopliae (robertsi), not less than 1,0×108 CFU/g, Beauveria bassiana, not less than 1,0×108 CFU/g), toxicological and hygienic assessment from the perspective of safety for human health and the natural environment, expert-analytical methods for studying scientific information on toxicological properties., hygiene, risk assessment

Results. Entomopathogenic fungi of the Metarhizium anisopliae and Beauveria bassiana preparations are capable of penetrating through the chitinous and other coverings of pests, affecting the fatty tissue and gastrointestinal tract. They decompose chitin and form a cottony mycelial growth on the bodies of pests, causing disruption of all organism functions. The chitinases of fungi decompose the chitin of phytopathogens, contributing to the destruction of plant disease agents. Fungi have the property of establishing themselves in the soil, providing the biological preparation with long-lasting action – suppressing the reproduction of insects. A promising direction of research is the combination of strains for the production of preparations that would be universal and affect more species of insect pests, as well as prolong the shelf life of entomopathogenic preparations.

Conclusions. The use of mycoinsecticides represents a crucial alternative for combating a complex of soil pests and can reduce the use of broad-spectrum pesticides on vegetable crops, thereby enhancing natural control by increasing the number of natural enemies. Scientific data regarding the features of technology for producing biological insecticidal preparations based on Bacillus thuringiensis, Metarhizium anisopliae (robertsi) and Beauveria bassiana have been summarized. Based on the results of the toxicological evaluation of the drug, it can be concluded that the biological product is safe enough for human health and the environment.

Keywords: toxicological and hygienic assessment, biological preparation with insecticidal action, Bacillus thuringiensis, Metarhizium anisopliae (robbertsi), Beauveria bassiana, agriculture.
