Summary. The aim of the work was to study the development of biologically harmless methods for controlling bee varroosis and optimization of geometric parameters of their means of implementation in order to increase the efficiency of honey bee product manufacturing. This work shows the results of analytical studies of the influence of electromagnetic radiation of the optical spectrum on bioobjects in the UV range (UVB, UVC) and in particular on the pathogenic microflora, the agents of various invasive and infectious diseases in honey bees, including varroosis. For the first time, we obtained mathematical expressions that simulate the dependencies of the electric power and design characteristics of protective devices that realize the operation of the entrance block equipped with LED modules of UV radiation when powered from solar cells. The manufacture of protective devices with scientifically grounded parameters allows optimizing of the power and quantity of UV-radiation LEDs, their placement in the tunnel of entrance block, to determine the wavelength, exposure, as well as the geometric parameters of LPRS‑1 entrance block, which provides the detrimental effect of UV radiation on the physiological functions of the Varroa mites. In addition, the application of entrance block for beehive provides sanitation of bees from varroosis without disrupting their natural rhythm of life, preventing the premature first cleansing flight of bee colony at unfavorable temperature conditions. This is due to the elongation of the path of bees from the hive’s hole to the exit from the tunnel of the entrance block formed by the upper and lower grids and the effect of ascending airflows, which enables the bees to adapt to the meteorological conditions and feel the low temperature of the outside air and return to the hive. In addition, the study of the proposed entrance block showed its functional ability to prevent the penetration of robber bees, wasps, hornets, and rodents to the hive due to the presence of a tunnel with calibrated inner air spaces. This creates conditions for restricting their direct access to the entrance of the hive, from where they smell the appealing odor of honey. The created device allows to prevent the infection of healthy bee colonies by due to the exclusion of the possibility of penetration into the entrance block of the hive of infected robber bees due to the presence of lattice tunnel, the inner surface of which is irradiated by sources of electromagnetic radiation of the optical range of the ultraviolet spectrum (LEDs). In this case, we observed the decreasing of bee colony biopotential as a result of the impossibility of attacking by its enemies (tits, jays, woodpeckers, etc.) due to the presence of limited space, formed around the entrance of the hive by a tunnel, bottom board and protective shield, that avoids direct contact of bees with their pests and enemies. The practical application of the entrance block provides protection against the take-off of bee colony and uncontrolled leave of swarm due to the presence of calibrated exit from the tunnel, which makes it impossible to leave of queen-bee with swarm or while taking-off by bee colony. Thus, the installation of the protective mean — multifunctional device (the entrance box is equipped with UV module powered by light-emitting diodes from photocells) allows to: (1) increase the efficiency of environmentally safe production technologies of beekeeping products by preserving the biopotential of bee colony and its honey products; (2) introduce more widely non-medicated biologically harmless technologies for the prevention and treatment of varroosis through the application of innovative solutions and means of their implementation of integrated protection of bee colonies during the production cycle, promoting the development of organic beekeeping, subject to increased profitability of honey farms and improvement of the production culture in the industry.
