    A comparative study on the quality of honey bee (Apis mellifera) queens developed from larvae after the collection of royal jelly
    (Bursa Uludağ Üniversitesi, 2022-12-08) Shaara, Hossam F. Abou
    Rearing bee queens is almost done utilizing grafting young larvae while the effects of grafting using old larvae after the collection of royal jelly on the quality of queens are not known. In fact, the production of royal jelly depends on grafting, then discarding the larvae to collect the royal jelly. This study aimed to investigate this point by grafting old larvae after removing them from their original cells without food. Larvae at age about 2 days were grafted into plastic queen cell cups (selection and grafting method or S&G method) leaving royal jelly behind and then resultant queens were compared with naturally reared ones (or NQ). The study showed the absence of significant variations between the queens reared from the two methods in characteristics of queens and cells. Meanwhile, no significant differences were found in regard to the performance of colonies. The colonies with queens from S&G method had slightly higher performance than those with NQ. The study concluded that grafting using old larvae without their original food does not impair the quality of queens. During the production of royal jelly, larvae may be grafted into new cells to continue their normal development instead of discarding them.

    Investigation of microorganism contamination points in beekeeping equipments with clinical signs of foulbrood in apiaries
    (Bursa Uludağ Üniversitesi, 2023-04-16) Borum, Ayşe Ebru; Çakmak, İbrahim; 0000-0002-8000-5770
    The goal of this study was to determine whether colonies with clinical signs of foulbrood in apiaries and hive tools, smokers, gloves, feeders and beekeeper's veils used in the same colonies were a reservoir source for microbial infections. For this purpose, samples were taken from colonies with clinical signs of foulbrood and collected from 29 different apiaries in the Southern Marmara region of Türkiye. The samples were brought to the laboratory under appropriate conditions, and agent isolation and identification were performed. Different microorganisms were isolated from the feeder, hive tool, beekeeper smoker, gloves and beekeeper suit samples collected from each apiary. Bacteria isolated from the samples taken from the hives with clinical signs of foulbrood and from the samples taken from the tools and equipment were isolated as the same species or as a mixture. As a result, an intense presence of microorganisms was detected in the hive tool, beekeeper suit, gloves, feeder, and beekeeper’s smoker, used by beekeepers, and it was determined that these materials used in beekeeping were a source of microbial reservoirs.

    Molecular identification of microbial pathogens in honey bees from Amasya
    (Bursa Uludağ Üniversitesi, 2023-05-04) Utkan, Neşe Gül; Eroğlu, Gözde Büşra
    Honey bees, Apis mellifera are highly beneficial insects that constitute both the livelihood of the producers and the food source of the consumers. However, there are some diseases that affect the yield of bees and cause the collapse of almost the entire colony. Most of these diseases are caused by microbial pathogens originating from viruses, bacteria, and fungi. Beekeeping is an important source of livelihood both in the center of Amasya and in almost all its districts. In this study, microbial pathogens that cause mass bee deaths and epidemics in Amasya province were determined using molecular methods. The results showed that the most common honey bee pathogens in Amasya are the Deformed wing virus, Chronic bee paralysis virus, and Aspergillus flavus fungus. Thus, the profile of bee diseases in Amasya province was determined for the first time with this study. In addition, this study guides other studies planned for the prevention of bee diseases and healthy beekeeping.
