Öğe Controlling Varroa destructor (Acari: Varroidae) in honeybee Apis mellifera (Hymenoptera: Apidae) colonies by using Thymovar® and BeeVital®(Avenue Media, 2008) Akyol E.; Yeninar H.This study was carried out to determine the effects of Thymovar® and BeeVital® on reducing Varroa mite (Varroa destructor) damage in honey bee (Apis mellifera L.) colonies in spring season. Average percentage of Varroa infestation level was determined as 24.27 on adult workers before the treatments. The drugs were applied two times on 25 September and 16 October 2006. Average percentage of Varroa infestation levels were determined as 5.18%, 10.78% and 35.45% after the first application, 1.90%, 7.05% and 61.15% after the second application in Thymovar®, BeeVital® and control groups, respectively. Average efficacies of Thymovar® and BeeVital® were found to be 96.91% and 88.66%, respectively. Difference between drug efficacies on Varroa mite was found significant (P<0.01). There was no queen, brood and adult honeybee mortality in all group colonies during the research.Öğe The effects of additive feeding and feed additives before wintering on honey bee colony performances, wintering abilities and survival rates at the East Mediterranean region(2006) Akyol E.; Yeninar H.; Sahinler N.; Guler A.In this study; the effects of additive feeding with vitamin, fumagillin and pollen supplement on survival rates, wintering abilities, amount of adult bees and brood production were examined at subtropical temperate region before wintering. The wintering ability, survival rates, adult bees and brood areas were positively affected by feeding and feed additives. The lowest values of research components were observed on unfed control groups colonies. © 2006 Asian Network for Scientific Information.Öğe The effects of varroa (varroa destructor) infestation level on wintering ability and survival rates of honeybee (apis mellifera L.) colonies [Bal ari{dotless}si{dotless} (apis mellifera L.) kolonilerinde varroa bulaşi{dotless}kli{dotless}k seviyesinin kolonilerin ki{dotless}şlama yetenekleri ve yaşama oranlari{dotless} üzerine etkisi](2011) Akyol E.; Yeninar H.This study was carried out to determine the effects of the Varroa (Varroa destructor) infestation level (in fall) on the wintering ability and survival rates of honeybee (A. mellifera) colonies. Four different infestation levels of Varroa in honeybee colonies were tested in this study. Ten honeybee colonies, in which infestation levels were similar, were used for each group. The average wintering abilities in low, medium, high and extreme groups were found to be 94.28%, 91.42%, 63.92% and 23.28% respectively. An average survival rate for the low, medium, high and extreme groups were found to be 100%, 100%, 80% and 40% respectively. Differences among the groups for wintering ability (P<0.01) were significant.
