“…There are studies [4] proving the strengthening of the antimicrobial effect of anolyte due to its bubbling with ozone. In the Kuban State Agrarian University, studies have been conducted to combat bee diseases by dissolving ozone in anolyte [5]. The results obtained show the high efficiency of the use of such solutions.…”

Analysis of the health status of bee colonies has shown that constant prevention and treatment of bees from concomitant diseases is necessary. The health of bees is directly related to their productivity. Most beekeepers use highly active chemicals to process beehives and inventory. To change this situation, it is necessary to search for new solutions for the treatment of bees. One of the ways to solve the problem is the use of environmentally friendly and harmless to bees and beekeepers electroactivated solutions obtained using diaphragm electrolyzers of water. The conducted studies of the developed model of a diaphragm electrolyzer using the Comsol program allowed us to obtain information about the physicochemical processes occurring in it over time. Comparison of simulation results and experimental data showed their good coincidence. Studies on the treatment of bee colonies in the apiary with electroactivated solutions can halve the use of chemicals and reduce the likelihood of drugs getting into bee products.

“…and Ovsyannikov D.A. [4,5] studied the processes at a constant mass of honey in the hive. However, at the end of winter, the mass of honey can significantly decrease, and this will affect the thermal conductivity of the whole object (the beehive) and the transient processes when the ambient air temperature changes.…”

Much research has been devoted to bee overwintering because it is the most dangerous period of the bee family’s life. The critical period for bees is the end of winter and the beginning of spring. During this time, there are large fluctuations in air temperature, and bees are forced to change their state from passive to active. By the end of winter, the club rises to the top of the hive, and the honey supply decreases significantly. Thus, this article considers a model that takes these changes into account. According to the results of the simulation, it was found that the movement of the bee club and the decrease of honey reserves in winter increase the fluctuations of the air temperature inside the hive. This affects the internal temperature regime of the bee club. At the same time, the stock of heat energy in the honey decreases and smoothes temperature fluctuations within the bee aggregation less. It is proposed to add a hive weight strain gauge to the previously developed electric bee heating control circuit, which will allow to correct the PWM output voltage coming to the heaters.

BACKGROUNDThe safety of fungal insecticides to apiculture is a public concern but remains poorly understood. This study seeks to evaluate whether, how and why wide‐spectrum Beauveria bassiana insecticides are safe to honey bees in a novel assessment system.RESULTSMesonotum dipping with a 108 conidia ml−1 suspension and body contact with conidial suspension in sucrose solution caused high mortalities of adult forager bees at 25 °C optimal for conidial germination and hyphal invasion. Intriguingly, colony sizes in the hives contaminated by the forager bees contacting viable and inactivated conidia at two sites (1.2 km in distance), respectively, showed similar increase percentages (31.7% versus 29.2%) during a 4‐week summer period of exposure to environment. No sign of fungal infection was found within each of the monitored colonies. Neither was fungal outgrowth observed on surfaces of bee cadavers cleaned from each hive at either site. Hourly counts of cleaned cadavers from videotapes presented no significant difference in colony‐cleaning behavior between the two sites. During the period, in‐hive temperatures at both sites were persistently stabilized at approximately 35 °C, which abolished conidial germination and were far above the out‐hive temperature range.CONCLUSIONIt is colony heating that protects honey bee populations from a risk of forager bees' contact with formulated conidia applied for arthropod pest control. No role was detected for colony self‐cleaning behavior in protecting the bee colonies from the risk. © 2020 Society of Chemical Industry
