Erdoğan, Yaşar; Erdoğan, Ümmügülsüm
This study evaluated the effects of chokeberry (Aronia melanocarpa) fruit powder as a functional dietary supplement for honey bee (Apis mellifera) colonies, focusing on colony development, antioxidant defences, nutritional status, behaviour, and honey yield under field conditions. A total of 48 colonies were randomly assigned to four feeding treatments (control, 2, 5, and 10 g L−1 chokeberry supplementation), with six colonies per treatment in each apiary (n = 6 per apiary; n = 12 per treatment). The experiment was conducted as a balanced field trial across two apiaries. Colonies were fed sucrose syrup supplemented with chokeberry powder for 21 days. Following the feeding period, colonies were transferred to two high-altitude summer apiaries where colony development, flight activity, defensive behaviour, antioxidant biomarkers, and end-of-season honey yield were evaluated. Results demonstrated that chokeberry supplementation significantly improved colony development, with significant dose effects on brood area and bee-covered frames (both p < 0.001). Flight activity also increased with supplementation dose (p < 0.001), whereas defensive behaviour was not affected. Total antioxidant capacity (TAC), superoxide dismutase (SOD), catalase (CAT) activity, and haemolymph total protein concentration all increased significantly with supplementation (all p < 0.001). End-of-season honey yield was significantly higher in supplemented colonies than in the control group (p < 0.001). Overall, these findings demonstrate that chokeberry fruit powder represents a promising functional dietary supplement capable of improving colony performance through the combined contribution of its nutritional composition and bioactive phytochemicals under practical field conditions.

Çıvracı, Sadık; Yalçın, Sakine; Onbaşılar, Esin Ebru
This study was carried out to determine the effects of seeds and roots of giant fennel (Ferula communis L.) on some performance characteristics of Apis mellifera caucasia L. colonies. Equalized colonies were distributed with 4 colonies for each group. In the study, 5 groups were arranged, and only syrup was given to the control group. On the other hand, 0.1% and 0.2% levels of root and seed of giant fennel were added to the syrup in the experimental groups. Measurements were made at 21-day intervals in the experiment. At the end of the experiment, supplemental feeding by adding fennel seeds and roots to the syrup provided a statistically significant increase in the number of bee frames, hive weight, nectar flow weight gain, and honey yield. Although the use of seed and root at the levels of 0.1% and 0.2% did not make a difference in these parameters, the use of the 0.2% level of seed had a more positive effect than the level of 0.1%. Usage of giant fennel seed and root increased total antioxidant status, total oxidant status, and oxidative stress index in honey according to the control group. The total antioxidant status in honey was increased statistically with the usage of 0.1% fennel seed. As a result of this study, it was concluded that the brood production and honey yield in honey bees and the antioxidant status in honey can be increased with the use of fennel seed and root, especially at the level of 0.2%, in supplementary feeding.

In this study, the effects of extracts obtained from medicinal and aromatic plants added to syrups used to feeding honeybee (Apis mellifera L.) colonies on some physiological characteristics of colonies were investigated. The experiment was carried out on 6 groups of 5 colonies. These groups are syrup (S), syrup + Urtica dioica (SU), Syrup + Melissa officinalis (SM), Syrup + Hypericum perforatum (SH), Syrup + Achillea millefolium (SA) and syrup + Thymus serpyllum (ST). As a result of the research, the sealed brood area data were determined as 3013.24±1939.26, 3107.00±2060.42, 3270.81±2194.80, 3091.20±1962.69, 3273.90±2095.49 and 3613.06±2348.27 cm2 in S, SU, SM, SH, SA, ST groups, respectively. When we compare the honey yields of the experimental groups, according to group S, SU increased by 18.48%, SM 43.10%, SH 16.04%, SA 27.35% and ST 53.86%. Therefore, syrup + medicinal and aromatic plant extract mixture given to honey bee colonies may have a positive effect on colony development and honey yield.

Cengiz, Mahir Murat; Erdoğan, Yaşar
In this study, wintering ability and some physiological properties of Buckfast, Carniolan, Caucasian and Erzurum honeybee genotypes were investigated in Eastern Anatolian conditions. During the wintering season of 2014, a total of 48 colonies, 12 from each of Buckfast, Carniolan, Caucasian and Erzurum honey bee genotypes, were taken from the equilibrated colonies of Langstroth type wooden hives for wintering. In the 2015 production period, a total of 43 colonies,11 from each of Buckfast, Carniolan, Erzurum genotypes and 10 from Caucasian genotype were used in the study. In the production season, the average number of combs covered with bees in genotype groups were found as 11.72±0.63, 12.17±0.62, 9.52±0.51 and 10.72±0.55 per colony, and the average brood areas were found as 2713.7±237.9, 2797.6±238.3, 2036.5±166.4, 2364.3±197.2 cm2/colony (19.04.2015-4.10.2015). The difference between the groups was found statistically significant (P<0.01) in terms of number of combs covered with bees and brood areas. Averarage honey yields were determined as 28.08±2.37, 29.94±2.17, 19.28±2.13 and 23.36±2.15 kg/colony, respectively. The difference between groups in honey yield was found statistically significant (P<0.05).
