“…The microflora of the bee organism can be nonpathogenic and acquire virulence under the influence of other factors -the manifestation of the action of specific causative agents of dangerous bee diseases -varroosis, tropilelapsosis, viral paralysis, and American foulbrood (AFB) (Odnosum et al, 2017;Yevstafieva & Nazarenko, 2018). In addition, the activation of conditionally pathogenic microflora can be under the influence of non-specific factors -hunger, cold, toxins, pesticides, or secondary pathogens that reduce the resistance of the bee organism (Kovalskyi et al, 2018;Kovalchuk et al, 2019).…”

The well-being of apiaries is a priority in the state's economic, social, and environmental aspects. There is a state monitoring system to ensure proper control over the prevalence of infectious, invasive, and viral diseases. This system systematically monitors the spread of diseases that cause significant economic problems. Solving these problems will further shape the state's favorability to ensure the export of beekeeping products to European countries. Data on the spread of infectious and invasive diseases of bees from official departments of the State Production and Consumer Services of particular regions. In work, such data were processed in the Volyn region from 2017 to 2022, including a plan for determining the incidence and incidence rates in this region. The results show that nosemosis and varroosis were the most common diseases in the Volyn region during the studied period. It was established that the indicator of bee colonies with the Varroa destructor mite in all analyzed years exceeds the incidence of nosemosis by 8.03 % (2020) – 24.49 % (2021). Moreover, the highest incidence of both diseases during the studied period was registered in 2021. In 2017, American foulbrood (AFB), created by a bacterium, was recorded in this region. The spread of bacterial diseases in bees is given. From the analyzed data, it is possible to note the imperfection of the monitoring system, as the research plans include a wide range of invasive diseases, but a small share is allocated to bacterial infections. Unplanned beekeeping studies include invasive and infectious diseases: bee bacteriosis and viral pathologies. The main problem is the low percentage of certified private farms. As a result, it is challenging to analyze damage to apiaries by contagious bee diseases. Thus, it is necessary to improve the state monitoring system, owing to which it will be possible to diagnose planned not only infectious and invasive diseases but also other diseases of bees that cause massive destruction of hives in apiaries of our state.
