    Beekeeping and recent colony losses in Turkey
    (Uludağ Üniversitesi, 2016-09-02) Çakmak, Selvinar Seven; Çakmak, İbrahim; Bursa Uludağ Üniversitesi/Arıcılık Geliştirme Uygulama ve Araştırma Merkezi.
    Beekeeping has a long history in Anatolia going back to Hittite civilization, B.C. 1300 about 9000 years. Also Turkey having at least five subspecies of Apis mellifera is a bridging country connecting Europe, Asia and Africa by Middle East and gene center of western Honey bee Apis mellifera. Anatolia also has three out of 37 phytogeography rich areas in the world and there are about 10.000 plant species and 3506 of them are endemic to this country. Turkey is representing one of the highest potential in world beekeeping with about 7,709,636 colonies, more than 150.000 families in beekeeping business, 79 Beekeeping Unions in each province as parts of Central Beekeeping Union of Turkey representing 56,000 professional beekeepers and 107,665 tons of honey production annually in Turkey. There are a number of factors affecting colony losses up to 80% high in some areas in Turkey including such as Varroosis, Nosemiosis, Foulbrood diseases, new generation of pesticides as neonicotinoids, queen failure, colony management and large scale long distance migratory beekeeping. Finally, Turkey still has great potential of genetic reservoir of western honey bee, Apis mellifera and may provide vital solutions for a number of beekeeping problems in the world facing today.

    The effects of different pollen trapping periods and intervals on amount of pollen and number of pollen collecting worker honeybees (Apıs mellifera L.)
    (Uludağ Üniversitesi, 2016-11-10) Akyol, Ethem; Unalan, Adnan
    This research was carried out to determine the effects of pollen trapping schemes on pollen gathering activity of worker honeybees in the Apiary of Omer Halisdemir University. In total 20 honeybee (Apis mellifera anatoliaca) colonies were used and divided randomly into four groups after they were equalized with respect to strength, brood area, food stocks and weight. Throughout the experiment, pollen traps were used every day in the first group of colonies, equipped with every second day in the second group of colonies in intervals of three days in the third group of colonies while the fourth group of colonies had no traps as used the control group. Throughout the experiment, pollen collecting bees from all colonies were monitored daily at five different times at the entrance of the hives for a period of ten minutes per time point. The first group gathered in average the maximum amount of pollen as to be 75.20±4.08 g/day/colony, the second and the third groups gathered in average 40.35±1.41 and 37.23±1.54 g/day/colony respectively. Significant differences were detected between the groups in respect of both the number of pollen collectors and amount of pollen. It was shown that colonies in all groups gathered the maximum amount of pollen at 7:00 a.m. (165.81±15.8 number/ten minutes/colony) and at 9:00 a.m. (177.39±20.06 number/ten minutes/colony) and the least pollen at 15:00 p.m. (19.52±1.68 number/ten minutes/colony).
