“…This highlights the need for good breeding practices in beekeeping, including such a trait as resistance to Varroa destructor, which is a breed feature, to reduce the infection rate of honeybees. According to the projected climate change, temperatures will continue to rise, which may affect the prevalence of viruses in wild bees and, as a result, in bee populations(Piot et al, 2022) A number of Ukrainian researchers are working on the problems of preserving the honey bee gene pool, and they believe that the solution to this is to create breeding programmes that improve the efficiency and behaviour of endangered breeds, while maintaining their adaptation to the environment(Hrechka & Senchylo, 2022;Cherevatov et al, 2014;Kerek, et al, 2017). This process of hardware is typical not only for Ukraine, and the first consequences can already be traced in research.…”

Bee breed is an important factor in determining bee family development and productivity, as it affects honey production, disease resistance, climate adaptation, and bee behaviour characteristics. The purpose of the study was to establish the relationship between the methods of mating queens and the morphological characteristics of bees of the Ukrainian steppe breed and the productive indicators of bee colonies. To conduct the research, 43 bee colonies with queen sisters of the Ukrainian steppe breed mated by different methods of natural mating were established in the Vinnytsia oblast. According to the results of mating, there were 22 queen bees in the control group, and 21 queen bees in the experimental group. The queens of the first control group mated in a normal natural way without any restrictions. The queen bees of the experimental group mated under time and space control. Based on the results of the research, the relationship between the integrity of the colony and its morphological features and productive indicators was established. Thus, experimental families have different degrees of belonging to the Ukrainian steppe breed, control – 59% and experimental – 87.2% (p < 0.001). According to the cubital index, the advantage was 8.2% (p < 0.001) in favour of the experimental group. The best family integrity on the hantel index was observed in families in which queens were mated in a controlled time and space, with a difference of 3.32% (p < 0.001). In the control group, where uncontrolled mating of queens was performed, more bees were found for discoid displacement with an excess of the standard indicator for the breed. Families in the experimental group were stronger by 14.5% (p < 0.001) compared to the control group. They provided 41.9% more honey, built 22.1% more honeycombs (p < 0.01), and the need for Kandy feeding was 31.8% less (p < 0.001). In addition, the bees of the experimental group had pronounced hygienic behaviour and required less labour costs. The practical significance of the study lies in the possibility of establishing patterns of action of factors on a particular breed and confirms the need to implement breeding programmes in beekeeping

The relevance of the conducted research is conditioned by the increase in demand for oilseeds with improved and environmentally friendly qualities, namely, the replacement of a dangerous solvent in the extraction process of processing oilseeds. In this regard, this paper is aimed at investigating the use of an organic solvent, such as ethanol, in extraction technology that is safer for human health. The leading approach to studying this problem is Soxhlet extraction and microwave extraction using hexane and ethanol solvents. The fatty acid composition of the resulting product was analysed by gas chromatography. In the proposed microwave method of oil extraction with a "green" solvent, which is ethyl alcohol, physical and chemical parameters were studied and compared with those obtained by the Soxhlet method.The efficiency of microwave processing is related to the heating process, which significantly increases the internal pressure of cells, which causes their destruction. A barodiffusion flow is created, which contributes to a significant increase in the yield of the extraction oil concentration by 1.4-1.8 times over the same time period and a decrease in the extraction process time by almost 3 times.
