    Effects of Additive Feeding with Pollen and Water on Some Characteristics of Honeybee Colonies and Pine Honey Production
    (2015) Halil Yeninar; Ethem Akyol; Alaeddin Yörük
    This study was carried out to determine the effects of additive feeding with pollen and water on honey yield, colony population, winter loses and wintering ability of colonies in pine honey production season in Muğla province of Turkey. Total twenty honeybee colonies had similar physiological pattern (queen age, genotype, amount of adult worker bees (number of frames covered with adult worker bees), sealed brood areas (cm2 ) and food stocks) were used and randomly divided into four groups. Three of them were fed extra with pollen+water, pollen and water. The control colonies were not given additive foods. Honey yield in pollen+water, pollen, water and control groups were found to be 24.2±1.1, 17.3±0.8, 16.3±1.0 and 12.0±0.6 kg/colony respectively. Group means were statistically significant. From September 25 to February 15 (wintering), losses of the adult worker bees in pollen+water, pollen, water and control groups were 50%, 69%, 68% and 82%, decrease of sealed brood areas in the groups were 48%, 66%, 68% and 85%, respectively. Wintering ability of pollen+water, pollen, water and control groups were found to be 92.1±3.2, 70.4±17.8, 67.1±16.7 and 51.0±21.2% respectively. The results showed that additive feeding in pine honey production season, especially feeding with both pollen+water provided nearly 100% more honey production and 80% better wintering ability than the control group. In addition, feeding with only pollen or water had similar positive effect (approximately 40%) better than control group

    The Effects of Varroa (Varroa destructor) infestation level on wintering ability and survival rates of honeybee (Apis mellifera L.) colonies
    (2011) Ethem Akyol; Halil Yeninar
    Bu çalışma bal arısı (A. mellifera L.) kolonilerinde Varroa (Varroa destructor) bulaşıklık seviyesinin kolonilerin kışlama yeteneklerine ve yaşama oranlarına etkilerini belirlemek amacıyla yürütülmüştür. Denemede dört farklı Varroa bulaşıklık seviysine sahip koloniler kullanıldı. Her grupta Varroa bulaşıklık seviyesi birbirine yakın 10 koloni ve dört grupta toplam 40 koloni kullanılmıştır. Düşük, Orta, Yüksek ve çok yüksek bulaşıklık seviyesine sahip gruplarda ortalama kışlama kabiliyeti sırayla %94.28, %91.42, %63.92 ve %23.28; aynı gruplarda ortalama yaşama oranı ise sırayla %100, %100, %80 ve %40 olarak belirlenmiştir. Kışlama kabiliyeti üzerine gruplar arasındaki farklılıklar istatistiki olarak önemli bulunmuştur (P<0.01).
