Erdogan, Ummugulsum; Erdoğan, Yaşar
Küresel iklim değişikliğine bağlı artan sıcaklıklar, arı aktivite desenlerini ve bitkilerin tozlaşma verimliliğini önemli ölçüde etkilemektedir. Bu çalışmada, ortam sıcaklığının çilek (Fragaria × ananassa) tarlalarındaki bal arıları (Apis mellifera) ve yabani polinatör arı türlerinin aktivitesi üzerindeki etkisi araştırılmıştır. Gözlemler, 12-22°C arasındaki sıcaklık aralıklarında farklı arı türlerinin çiçekleri ziyaret sıklıkları kaydedilerek yapılmıştır. Bulgular, A. mellifera'nın tüm sıcaklık aralıklarında gözlendiğini ve aktivite seviyesinin sıcaklık arttıkça önemli ölçüde arttığını göstermektedir. Yerli türler arasında Lasioglossum spp. ve Halictus quadricinctus daha dar sıcaklık aralıklarında aktifken, Eristalis tenax daha yüksek sıcaklıklarda en yüksek aktivitesini göstermiştir. Genel olarak, bal arıları geniş bir termal toleransa sahipken, yerli arı türleri daha sınırlı sıcaklık aralıklarında faaliyet göstermektedir. Bu sonuçlar, yerli arı topluluklarının iklim değişikliğinin ilerlemesiyle tozlaşma hizmetlerinin azalması riskiyle karşı karşıya olduğunu ve bu türlerin korunmasının tarımsal sürdürülebilirlik için önemli olduğunu göstermektedir.

This study was conducted using a Cross-Sectional Observational Design to determine the effects of current managerial practices applied in commercial dairy cattle farms in Çorum Province on calf survival. The main material of the study consisted of 120 active farms, which represent the general structure of the dairy cattle sector in the region. Data were collected via face-to-face surveys, and the scale’s reliability was confirmed (Cronbach’s Alpha: 0.742) and suitability for Factor Analysis (KMO: 0.710) was verified. The results showed that while 88.33% of the farmers were members of a cooperative/union and 57.50% reported timely colostrum administration (within the critical <4 hours), these positive indicators contrasted sharply with low biosecurity and poor practical application. Specifically, calf mortality was high (42.50% of farms reported mortality rates >5%), mainly due to diarrhea and pneumonia, with 65.83% of deaths occurring in the first 30 days. Critical management deficiencies included uncontrolled colostrum feeding (85.00% via suckling, risking failure of passive transfer), severe biosecurity breaches (85.83% of calves housed with adult animals), and delayed introduction of solid feed. In conclusion, the primary challenge in Çorum is not lack of institutional access or basic knowledge, but rather a critical disconnection between theoretical knowledge and practical management implementation. To improve calf survival, management strategies should shift from traditional suckling to controlled colostrum protocols and emphasize the transition from group housing to individual calf hutches to ensure biosecurity.

İncele - MakaleAçık Erişim2026Scopus SJRQ4Climate-driven synchronization of honey bee flight activity and plant phenology in Türkiye: development of a Beekeeping Climate Suitability Index (BCSI)
Erdoğan, Yaşar; Erdoğan, Ümmügülsüm
Honey bees (Apis mellifera L.) provide essential pollination services that depend on the temporal synchronization between flight activity and plant flowering phenology, both strongly influenced by climatic conditions. However, this relationship remains insufficiently quantified at large spatial and temporal scales. In this study, we quantified climate-driven honey bee flight activity and its alignment with flowering phenology of major nectar plants in Türkiye using ERA5-Land data for the period 1981–2023. Suitable flight days were defined based on temperature (≥12°C) and precipitation (0 mm), and seasonal suitability was evaluated at a monthly scale. A composite Beekeeping Climate Suitability Index (BCSI) was developed by integrating flight activity, flowering overlap and nectar flow window. The number of suitable flight periods ranged between 4 and 7 months (mean ≈5.5), indicating substantial interannual variability. Flight flowering synchrony was low for early-spring species (23–35%) but reached 100% for summer species. BCSI values ranged from 0.44 to 1.00, capturing variability in climatic suitability for beekeeping. These findings demonstrate that climatic variability plays a decisive role in shaping bee plant interactions and provide a quantitative basis for climate-informed beekeeping management.

Erdoğan, Yaşar
Varroa destructor is a destructive ectoparasite of honeybees (Apis mellifera). This study investigates the chemical composition and bioactivity of essential oils obtained from three medicinal plants (Origanum acutidens, Satureja hortensis, and Juniperus communis). The chemical components of the essential oils were determined by Gas Chromatography-Mass Spectrometry (GC-MS). These oils were evaluated for their acaricidal, repellent, and insecticidal activities against V. destructor, as well as their lethal effects against honeybee larvae. The results revealed that the essential oils of O. acutidens (LC50: 2.18, LC90: 6.07 µL/L) and S. hortensis (LC50: 1.79, LC90: 5.77 µL/L) exhibited strong acaricidal effects, while those of J. communis (LC50: 3.75, LC90: 4.16 µL/L) exhibited moderate activity. S. hortensis showed the highest repellent effect against V. destructor (ED50: 0.44, ED90: 1.25 µL/L), followed by O. acutidens (ED50: 0.58, ED90: 4.22 µL/L) and J. communis (ED50: 0.87, ED90: 46.3 µL/L). Furthermore, the larval mortality rates remained below 5% in all treatments, indicating negligible toxicity to honeybee larvae. Overall, this study highlights for the first time the comparative acaricidal and repellent efficacy of these three essential oils under identical experimental conditions, emphasising their potential as natural and environmentally friendly alternatives for controlling V. destructor. Further research is needed to optimise application methods and evaluate long-term effects under field conditions.

Erdoğan, Yaşar; Erdoğan, Ümmügülsüm
Aim of study: The aim of this study was to evaluate the effects of a phenolic-standardized flower extract from Crataegus orientalis Pall. on honey bee colony development and end-of-season honey yield under field conditions, and to assess its lasting colony-level effects. Area of study: The study was conducted during the 2025 beekeeping season at the apiary of Bayburt University Beekeeping Application and Research Center, located in northeastern Türkiye. Material and methods: Twenty-four initially balanced honey bee (Apis mellifera L.) colonies were randomly assigned to four groups (n = 6): a control group receiving 1:1 sucrose:water syrup and three treatment groups receiving 50, 100, or 200 mg GAE L⁻¹ of phenolic-standardized Crataegus orientalis flower extract. Colonies were fed daily for 21 days in early spring and monitored at seven time points (T0–T6) from mid-May to late August. Colony development was assessed using brood area (cm²) and number of frames with bees, while hive-front dead bees were recorded as a safety indicator. Net honey yield was determined at the end of the season. Main results: Daily syrup consumption did not differ among groups (P > 0.05), whereas daily phenolic intake increased in a dose-dependent manner (P < 0.05). Brood area increased significantly with dose and was generally higher in the high-dose group than in the control group throughout the season (P < 0.001). No significant differences were observed among groups for seasonal averages of frames with bees or mortality index; however, a significant treatment × time interaction was detected for frames with bees. Net honey yield was significantly higher in the high-dose group compared to the control group (P < 0.01). Research highlights: Short-term early spring supplementation with phenolic-standardized Crataegus orientalis flower extract supported brood development without increasing adult bee mortality. This early developmental advantage resulted in a measurable improvement in end-of-season honey yield under field conditions.

In this study, seventeen floral honey samples collected from Türkiye’s Çoruh Valley were examined and a total of 59 parameters were analyzed to evaluate their quality attributes. Accordingly, hydroxymethylfurfural (HMF), diastase activity, fructose, glucose, sucrose, total fructose + glucose (F + G), the fructose/glucose ratio (F/G), color and δ13C isotope values were determined together with amino acid profiles, organic acid composition, mineral contents, and phytohormone profiles. All chemical and biological data were evaluated using multivariate statistical approaches, including Principal Component Analysis (PCA), Pearson correlation analysis and Hierarchical Clustering Analysis (HCA), to characterize similarities and differences among the samples. The analytical results demonstrated that honeys from this region comply with established quality standards and exhibit natural purity, balanced chemical composition, and favorable nutritional properties. The detection of diverse phytohormone types and concentrations across the samples, as revealed by the analyses, indicates a rich biochemical signature originating from plant sources. This finding also highlights the functional properties, biological value, and nutritional significance of these honeys. Overall, the results confirm that the floral honeys obtained from Türkiye’s Çoruh Valley are high-quality products in terms of both chemical and biological properties.

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.

This study investigated the effects of electromagnetic fields (EMFs) from electric fence systems on physiological and reproductive parameters of male honeybees (Apis mellifera caucasica). The study was conducted between May and August 2024 at the Bayburt University Beekeeping Application and Research Center, with five experimental groups. Hives were positioned at varying distances (1–2.5 m) from the fence. The findings showed that the average body weight (245.4 mg), sexual maturity rate (58.56%), and sperm concentration (0.87 ± 0.04 × 10 ⁶/µL) of drones closest to the electric fence were significantly reduced (p < 0.05). The electric field effect was limited in groups at greater distances, with statistically insignificant differences in some parameters. No significant differences were found between groups in sperm volume. Results demonstrate that electric fields from fence systems suppress developmental processes and reproductive physiology of drones in a distance-dependent manner. Lower body weight, decreased sperm concentration, and proportion of mature males in colonies near the fence show electromagnetic stress is a significant risk for bee health. Future studies should examine the effects of electromagnetic fields at different frequencies and strengths on larval development, sperm morphology, oxidative stress markers, and gene expression profiles.

Erdoğan, Yaşar
Numerous flowering plants rely on bees for pollination. Any natural or anthropogenic factor that threatens colony survival can have a large impact on plant production. This study investigates the effects of manmade hives built from different materials and how these may influence colony growth. Ten each of three hive types were selected, wooden, polystyrene and composite insulated hives. Factors of adult bee numbers, brood development, nectar flow period weight gain, bee flight activity, aggression response, and honey yield were selected markers of hive development. Statistically, each hive type produced significant variation (p<.05). The greatest overall productivity across all factors was for insulated hives made of composite material, with honey production approximately 35% times that of wood, 14% times that of polystyrene and in terms of the development of honeybee colonies, the average of other hives is 10.2 times.Highlights Relative humidity and temperature are important environmental factors for honeybees. Insulated hives, increased honey yield. High temperature and humidity inside the hive made honeybees more aggressive.

This study was conducted in 2018 in order to determine the effects of an electric fence system on honeybee colonies housed in hives made from different materials. The experiment was carried out with honeybee colonies of 36 Caucasian races (Apis mellifera Caucasica) in full-size Langstroth hive. In terms of mean values of the aggressive behaviour of honeybee colonies were found to be the highest (13.57 number/colony) application group where the conductor wires of electric fence system are within a 1 m distance from hives and the lowest (2.39 number/colony) were obtained from control application group. The highest mean values adult bee development (23.76 ± 12.34 number/colony), development of brood area (5421.25 ± 1432.75 cm 2 /colony), nectar flow period weight gain (46.42 ± 3.61 kg/colony), flight activity (107.38 ± 11.74 number/colony) and honey yield (21.55 ± 1.54 kg/colony) were determined in control groups. When the average values of honeybees robbing behaviour were examined, the highest value (3.33 ± 0.32 number/colony) was determined in the control groups. This experiment shows that the electromagnetic and electric fields produced by the electric fence system have negative effects on honeybees. In order to minimise the negative effects of the electric fence system on the bees, hives should be covered with a metal screen or should be placed long distance (minimum 2 m) from the electric fences.Highlights The electric fence system is the most effective method of keeping honeybee colonies. At the same time, the electric fence system disturbs the honeybees. All negativity can be completely eliminated by simple measures.

The majority of farm households in Turkey and especially the Eastern Anatoliaare still based on low-input semi subsistence agriculture and livestock production. Despite a slow decline in recent years, agriculture and livestock production remains a major employer in Turkey and it is a significant contributor to the country's gross domestic product, GDP. Whist Turkey is one of the EU candidate countries, is self sufficient in food production and Turkish agriculture is poorly structured inefficient, with farming in the Eastern Anatoliabeingmainlysubsistencefarming. Yet,thesetraditionalruralstructures combined with poor access to low level of education and low level of off-farm unemployment problem makes the situation more complicated and unsustainable.

Eastern Anatolian livestock producers and the farmers have the ambitions to take part in future progress because the region is naturally organic not by design but default.It is for sure that present potential of the region has not been fully determined and utilized. EU has greatly benefited from previous enlargements economically, politically and socially. When European Union (EU) and Turkish Government relations considered and accession of Turkey to EU would be the logical consequence of the previous accessions. The screening on chapter 11 (Agriculture and rural development) is one of the important criteria and Turkey is working on to meet these benchmarks.
