    Composition and Physico-Chemical properties of lyophilizet royal jelly
    (Uludağ Üniversitesi, 2011) Balkanska, Ralitsa; Kashamov, Borislav
    The aim of the research was to study some of the components and physico-chemical properties of lyophilized royal jelly (LRJ). Six royal jelly samples produced in Bulgaria were lyophilized. The samples were preserved at -18 0C before analysis. Water content, proteins, lipids, sugars, ash, pH, total acidity and electrical conductivity were analyzed. It was found that LRJ contains: water (3,49–4,76%), lipids (3,09–8,56 %), fructose, glucose and sucrose (24,27–32,67 %), ash (2,50–3,03 %), pH (3,8–4,0), total acidity (10,67–12,88 ml 0,1 N NaOH/g). The values of LRJ electrical conductivity of 1 % water solution was in the range 421–481 µS/cm.

    A preliminary study on discrimination of different ısfestation levels of parasite (Varroa destructor) by Wing geometric morphometric analysis on honey bees
    (Uludağ Üniversitesi, 2011) Özkan, Ayça; Kandemir, İrfan; Çakmak, İbrahim; Çakmak, Selvinar S.; Uludağ Üniversitesi/Mustafakemalpaşa Meslek Yüksekokulu.
    The goal of this study was to investigate the possibility of using geometric morphometric method to discriminate different infestation level of Varroa mites (Varroa destructor) in honey bees. Three colonies of honeybees (Apis mellifera anatoliaca) were used as control, moderate and high infested with varroa mites. For geometric morphometric analysis of fore wings of worker honey bee, each left wing image of samples were archived and labelled with unique codes in the computer and a total of 139 wings of worker bee belonging to 3 colonies (2-Varroa infested colonies and 1-Control group) were used. All three groups of control, moderate and high infested colonies were discriminated clearly. The results here suggest that geometric morphometric analysis of honeybee wings can be used to discriminate different varroa infestation level.
