“…Petersen et al(2020) point to the fact that obstacles to breeding honeybees are the lack of pedigree due to free mating, and low penetration of genetic improvement into the general population. The conducted studies of morphometric characteristics of bees of the Ukrainian steppe breed confirm the results of Ukrainian and foreign researchers on the level of purebred breeding in apiaries(Kerek, 2020). According to these characteristics, the belonging of bees to the breed with uncontrolled mating of the queen was 59.0%, and with the control of this process in time and space -87.2%, which is 28.2% higher (p < 0.001).…”

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.

“…Research on the morphometry of Carpathian bees, initiated by Ukrainian researcher A.Haidar, is continued in the breeding and selection laboratory for Carpathian bees at the "P. I. Prokopovych Institute of Beekeeping", Mukachevo, Zakarpattia region. Through selective breeding based on exterior traits, phenotypic characteristics of four Carpathian bee types -"Vuchkivsky", "Rakhivsky", "Hoverla", and "Synevyr" -have been sufficiently stabilized, as reflected in the works of Kerek et al (2017Kerek et al ( , 2018Kerek et al ( , 2020, Pappa et al (2017a), andMertsina (2006). According to these publications, bees from this region are likely to belong to the A. m. carnica subspecies.The study of morphometric wing indicators of worker bees from selective crosses of Carpathian bees provides grounds to assume significant differences between the phenotypes of local populations and Western selection lines (Petko & Fedorovich, 2022).…”

Today, there are no systematic studies on the wing phenotypes of drone populations of the honeybee widespread in Ukraine. Considering that drone genomes are haploid, this allows one to establish the correspondence between the phenotype and the drone genome, thereby roughly determining the queen's genome in the part responsible for the wing phenotype. This partially compensates for the lack of resources among domestic scientists to conduct genetic research on bees. The aim of the study was to examine the wings of drones from several apiaries in the Kharkiv, Sumy, Poltava, and Zhytomyr regions, identify typical phenotypes, and attempt their taxonomic identification. Using discriminant analysis, 4640 drone wings were classified into three clusters. A two-step scheme for forming significantly different phenotype clusters of wings was proposed. Initially, based on the similarity of Euclidean distances and Mahalanobis distances (<2.6) between clusters, three groups were obtained, which, for refinement, underwent a second classification. As a result, average values and confidence intervals of eight morphometric traits were established: Ci, Dbi, Disc.sh, Pci, Ri, Ci.3, Ci.2.1, Ci.2.2 for the three wing groups. It is suggested to accept the trait values of these groups as reference data: one as a local population of the A. m. carnica subspecies, and the other two as regional standards for Ukrainian bees. Based on the obtained standards, a significant presence of A. m. carnica subspecies bees was established in all studied apiaries, except for the apiary with the status of a breeding ground for Ukrainian steppe bees (Kuzemin village, Sumy region), where such presence is minimal. This fact indicates the need for special measures to reproduce and expand the ranges of existence of local populations of Ukrainian steppe bees. The example of creating local and regional morphometric standards provided in this work is specifically designed to address this issue.
