Serednyak D. "ECOTOXICOLOGICAL JUSTIFICATION FOR THE PROTECTION OF GRAIN STOCKS FROM COLEOPTERA PESTS (COLEOPTERA) BY THE METHOD OF FUMIGATION"

Objects of study: pests - rice weevil (Sitophilus oryzae L.), granary weevil (Sitophilus granarius L.), small mealworm (Tribolium confusum Duv.); Subject of study: improvement of disinfection with phosphine-based preparations against the most common grain pests by the method of fumigation fumigants (phosphine-based preparations). Goal and objectives of the study. Ecotoxicological feasibility study of modes of fumigation against the most common grain pests, using phosphine-based preparations, specifying the required lethal norms of product of average concentration and time (PACT). The species composition and features of the biology of the most widespread pests of grain stocks are specified. Dominant types of pests are determined. The modern phytosanitary condition of granaries is investigated. The system of measures to protect grain from the most common pests of grain stocks by fumigation has been improved. The modes of fumigation are determined using different temperature parameters. The necessary lethal norms of an average concentration of phosphine against the most common pests of grain stocks at different stages of their development have been established.
