- 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.
- MakaleAçık Erişim2026Scopus SJRQ1Chemical composition acaricidal activity and honeybee safety of essential oils from Origanum acutidens, Satureja hortensis, and Juniperus communis against Varroa destructor
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.

Tosun, Murat; Cengiz, Mahir Murat; Erdoğan, Yaşar; Turan, Metin
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.

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.

Turk, Bahar; Yildiz, Tugba; Dursun, Mehmet Tahir
Within the context of tourism-related activities, numerous factors may influence a traveller's choice of destinations. Therefore, it is crucial to understand which factors will mostly influence destination selection. It is common knowledge that in a destination selection process, people are likely to visit sites they believe are worthwhile. The Analytical Hierarchy Process (AHP) was used in the study, and the data were collected from twelve experts, including six academicians of tourism and destination marketing, and six tour guides with more than ten years of experience in the sector. The research aims to determine the priority order of consumption values in determining the preferences of tourists for the destinations they have selected. The results show that epistemic value was the most important factor in determining a tourist's choice of destination. Moreover, it was found that the following dimensions, namely functional value, i.e., worth the money, emotional value, i.e., feel secure, social value, i.e., meet friendly and hospitable people, epistemic value, i.e., providing novelty experiences, and conditional value, i.e., personal safety have also been given priority. By identifying the priorities of a tourist in the destination selection process, it is envisaged that tourism businesses operating in tourist destinations will be able to provide better value-added activities, such as in food and beverage, lodging, entertainment, and travel agencies. In providing theoretical and empirical information for those involved in the sector, a more efficient process is thus ensured. With the help of this knowledge of what is expected of tourists as consumers, it will be easier to develop comprehensive strategies and solutions.

Yildiz, Tugba; Devecı, Fatma Gorgün
This study aims to determine the effect of consumer minimalism on sustainable consumption and to reveal the mediation effect of perceived consumer effectiveness. The research sample consisted of 1010 consumers aged 18 and above. Structural equation modeling and Process Macro were utilized in data analysis. According to the findings “clutter removal” and “longevity” have an effect on “perceived consumer effectiveness”. Perceived consumer effectiveness has an effect on “rethinking”, “reusing”, “refurbish”, “reuse” and “repurpose”. Further, “clutter removal” and “cautious shopping” has a direct effect on “rethinking”, “refurbish” and “reuse”. “Longevity” has a direct effect on “reusing”, “refurbish” and “repurpose”. Finally, “self-sufficiency” has a direct effect on “rethinking”, “refurbish" and “repurpose”. Mediation effects have been revealed by adding the “perceived consumer effectiveness” variable to the direct effect model for the “clutter removal” and “longevity” dimensions.
