Kisil D. Substantiation of veterinary and sanitary measures in apiaries for the prevention of infectious diseases

The dissertation is devoted to the research of the spread of mixed diseases of honey bees in the apiaries of Okhtyrka district of Sumy region, development and application of ecologically safe devices, their introduction into the beekeeping industry. It is established that the analysis of the state veterinary reporting for the period from 2015 to 2020 does not reflect the real epizootic situation regarding the incidence of bees with infectious diseases. Our epidemiological studies in apiaries in different regions of Ukraine, provided an opportunity to more extensively and objectively assess the epizootic situation in the field of beekeeping. According to the district laboratory for the study of bee diseases, during this period, the number of cases of infectious diseases gradually increased in the apiaries, and at the same time increased the number of disadvantaged points. At the same time, there was a growing trend of mycoses and parasitic diseases. It was found that mostly infectious diseases began to be registered in the form of a mixed infection, which made it difficult to make a reliable diagnosis. During the first stage of the dissertation research on the epizootic situation in the apiaries of Okhtyrka district of Sumy region, a high proportion of unfavorable points for infectious and parasitic diseases was found, in which the incidence ranged from 9 to 59%. This indicated a significant spread of infectious diseases in regions with developed beekeeping. At the same time, it should be noted that in cases of detection of a mixed form of the disease, different infectious diseases had different epizootic indices. The incidence rate in most cases was the highest for American rot, ascariasis and varroasis, which indicated the long–term distress of the surveyed apiaries.
