In vitro spermatological parameters in drones
(Bursa Uludağ Üniversitesi, 2023-05-18) Kaya, Abdulkadir; Uysal, Ongun
Honey bees are an indispensable element of the ecosystem, as they provide an important part of plant pollination beyond food production. The queen bee, which forms the core of the bee colony, is at the center of bee production in the beekeeping sector. Undoubtedly, the production of high-quality queen bees primarily depends on suitable drones and therefore, quality sperm. In addition, artificial insemination of queen bees is a successful production method, as in other species, due to its superior characteristics compared to natural mating. In many apiaries and research centers, artificial insemination is used routinely for queen production. One of the advantages of this method is that the sperm can be preserved for the short or long term. In this respect, it is very effective in protecting genetic resources, preventing bee diseases and facilitating bee transportation. Today, spermatological studies and parameters used in drones are very few compared to other species. With the increasing importance given to the subject in recent years, many spermatological parameters have started to be used in honey bees. However, the morphological and physiological differences of drone semen require the development and standardization of these parameters with further studies. In this review, the spermatological parameters used in drone semen, together with the working principles and materials used, were examined in general terms and presented to the readers.

Antioxidants play a crucial function in fighting free radicals that can harm biomolecules in the human body and damage cells, which can lead to immunological disorders including inflammation. In this research, we evaluated bee pollen extracts from six stingless bees (Heterotrigona itama, Tetragonula reepeni, Tetragonula testaceitarsis, Tetragonula fuscobalteata, Tetragonula iridipennis, and Tetragonula pagdeni) processed using different drying methods for antioxidant and anti-inflammatory activity. Each sample was divided into two specimens, where one was processed by ovendrying at 40ºC and the second was chilled at 4 ºC, then extracted by ethanol. The extracts of T. fuscobalteata had the highest antioxidant activity when dried in an oven with an IC50 value of 36.47 µg/mL, while T. reepeni using a chiller was 41.30 mg/mL. The highest anti-inflammatory activity was for oven-dried T. fuscobalteata with an IC50 of 39.70 mg/mL, while chilled T. reepeni was 34.30 µg/mL. Different drying techniques can affect the antioxidant and anti-inflammatory activity of bee pollen extracts as well as their potential as food, pharmaceutical and cosmetic ingredients.

This study was carried out to determine the honey, pollen and propolis amounts and honey qualities obtained from the bee pasture established in Bingöl University between the years 2021-2022 and highland and to compare the bee pasture and the highland in terms of these characteristics. 10 beehives were used in the study. Five beehives were left in the bee pasture, and 5 of them were taken to the highland for comparison. The quantities of honey, pollen, and propolis per hive and the moisture, diastase, HMF, commercial glucose, C13 sugar, C4 sugar, and the difference between raw protein in honey and delta C13 sugar of honeys were determined for both locations. These quality parameters obtained were evaluated according to the Turkish Food Codex Honey Communiqué. As a result of the research, it was determined that there was no statistical difference between the amounts of pollen and propolis obtained from the bee pasture and the highland, and the amount of honey obtained from the highland was higher than the bee pasture. In addition, it has been determined that the honey obtained from both bee pasture and highland is at the "appropriate" level in terms of the limit values determined by the Turkish Food Codex Honey Communiqué in terms of quality criteria. In the light of these data, it has been understood that although the honey yield from bee pasture is low, it is sustainable and can be an alternative to migratory or highland beekeeping.

This article examines the physicochemical and nutritional characteristics of honey produced in different regions of Kosovo. The aim of this study is to investigate the physicochemical properties and nutritional characteristics of honey from various regions in Kosovo, shedding light on the factors influencing its composition and quality. It also underscores the importance of local beekeepers in sustaining honey production and environmental preservation. A total of 26 samples were gathered from various locations, and beekeepers were interviewed about their honey-production techniques and bee-feeding practices. The samples underwent analysis to determine parameters such as moisture content, total solids, pH, acidity, ash content, proteins, electrical conductivity, and dissolved solids content %. Notably, the physicochemical properties of honey differed significantly across the regions. Moisture content ranged from 15.02% to 18.80%, with the lowest found in Ferizaji and the highest in Sharri. Dissolved solids content % concentration at 20°C varied from 79.50% to 82.60%, with Sharri exhibiting the lowest and Prishtina displaying the highest value. The acidity and pH levels of all honey samples were measured between 4.97 and 5.63, and 3.56 to 5.60, respectively. Additionally, the Pfund scale was employed to evaluate the color of the honey, indicating white hues for Sharri, extremely light white or white for Prishtina and Ferizaj, and exceptionally white for Skenderaj. This study concludes that geographical location, feeding systems, nectar sources, honey age, and beekeeper processing methods significantly impact the physicochemical and nutritional properties of honey, including its color.

(Bursa Uludağ Üniversitesi, 2023-10-31) Sabatına, Paulraj; Srınıvasan, Madapuji Rajagopalan; Murugan, Marimuthu; Samınathan, Vangili Ramasamy
The present study was conducted to find the diversity of stingless bees (Tetragonula sp.) in Coimbatore, Madurai, Dindigul, and Trichy districts in Tamil Nadu, India. Adult worker bees were collected from feral stingless bee colonies from 16 locations, four from each district. The collected stingless bees were preserved in 70% alcohol (ethanol) and examined under a Leica stereo zoom microscope. Seventeen morphometric key characteristics were measured to know the diversity of stingless bees. The results revealed that two species of stingless bees, Tetragonula iridipennis and T. laeviceps were prevalent in the four selected districts of Tamil Nadu. Four vital morphometric characters of the worker bees namely the head width, the forewing length, the hind tibial length, and the whole body length helped to distinguish the two Tetragonula sp. Among all the locations, the bees collected from L1- Insectary, TNAU, Coimbatore had much higher values of the above four morphometric characters (1.67mm ± 0.04, 3.69mm ± 0.02, 1.53mm ± 0.01 and 3.98mm ± 0.14 respectively) and were identified to be T. laeviceps based on these key morphometric characters. The bees from rest of the 15 locations which had the morphometric values 1.59 to 1.61 mm, 3.20 to 3.41mm, 1.34 to 1.43mm and 3.51 to 3.65mm respectively were categorized as T. iridipennis.
