Semen samples obtained from sexually mature drones were pooled. Then, pooled semen was diluted with different concentrations of L-carnitine (2.5 mM/5 mM/10 mM) and without L-carnitine (control) supplemented extenders. Motility, plasma membrane functional integrity, acrosomal integrity and mitochondrial function were negatively affected by the cryopreservation process but DNA integrity was not affected. Malondialdehyde (MDA) concentration was used for analyzing the membrane lipid peroxidation status and a better result was obtained in the LC5 group compared with the control group at post-thaw. L-carnitine groups had a positive effect on sperm motility, plasma membrane integrity, and mitochondrial function compared to the control group (P<0.05). Acrosomal integrity was better preserved in the LC5 group compared to the control group. The study shows that LC supplemented extenders have beneficial effects on honey bee drone sperm parameters. The results of the present study demonstrated the beneficial effect of using a 5 mMol LC supplemented extender.Publication Testing the pesticide avoidance hypothesis by bees and flies in a mediterranean arthropod community(Oxford Univ Press Inc, 2015-04-01) Plascencia, M.; Carson, R.; Hranitz, J.

Sexually mature drones were used for semen collection. Pooled semen was diluted with TL-Hepes based extender supplemented with different concentrations of BSA (1 mg/mL, 3 mg/mL, and 5 mg/mL) or without BSA (control), at a final concentration of 100x10(6) spermatozoon/mL. Motility, plasma membrane functional integrity (HOST), and defected acrosome (PSA-FITC) were evaluated in the study. At post thaw, the highest sperm motility rates were obtained in the BSA5 group (P< 0.05). Functional integrity of sperm membrane was better preserved in the BSA3 and BSA5 groups compared to the other groups. The acrosomal integrity rates were higher in BSA5 group than in control group (P< 0.05). The study shows that bovine serum albumin supplemented TL-Hepes based extenders have beneficial effect on drone semen parameters at post-thaw. The results of the study demonstrated a notable advantage of using 5 mg/mL of BSA in TL-Hepes based extender.Publication Sublethal effects of deltamethrin on apis mellifera in Turkey(Oxford Univ Press, 2015-04-01) Salazar, T.

We determined that 19 apiaries were infected and the suspected clinical signs of foulbrood diseases were investigated in 102 beehives by PCR and cultural method. Broods and combs from colonies with suspected clinical symptoms of foulbrood diseases were collected and cultured for bacteriological examination. All of the specimens contaminated with bacteriae and 37 species of bacteriae were isolated such as Stapylococcus epidermidis, Bacillus subtilis, Corynebacterium jeikum, Corynebacterium pseudotuberculosis, Bacillus spp. All of these bacteria are related to human, animal and environmental origins. In this study, Paenibacillus larvae by PCR amplifying the 973-bp region PL1 and PL2 with 1f, Melissococcus plutonius amplifying the 973-bp region EFB-F and EFB-R gene were amplified. American Foulbrood causative agent Paenibacillus larvae and European Foulbrood causative agent Melissococcus plutonius were not detected in any sample examined by PCR and cultural methods. On the other hand, Paenibacillus alvei that is a seconder agent to European Foulbrood was found in two samples by cultural methods. In conclusion, the results showed that P. larvae and M. plutonius are not present in South Marmara Region. In this study, human, animal and environment originated agents were isolated.Publication Effects of honey enrichment with Spirulina platensis on phenolics, bioaccessibility, antioxidant capacity and fatty acids(Elsevier, 2021-09-12) Güldaş, Metin; Gürbüz, Ozan; Çakmak, İbrahim; Yıldız, Elif; Şen, Hasan; GÜLDAŞ, METİN; GÜRBÜZ, OZAN; ÇAKMAK, İBRAHİM; YILDIZ, ELİF; Bursa Uludağ Üniversitesi/Sağlık Bilimleri Fakültesi/Beslenme ve Diyetetik Bölümü.; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Gıda Mühendisliği Bölümü.; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Zootekni Bilimleri Bölümü.; Bursa Uludağ Üniversitesi/Arıcılığı Geliştirme Uygulama ve Araştırma Merkezi.; Bursa Uludağ Üniversitesi/Keles Meslek Yüksekokulu/Gıda Teknolojisi Bölümü.; 0000-0002-5187-9380; 0000-0001-7871-1628; 0000-0003-1356-9012; GLT-7125-2022; AAG-6424-2021; U-1332-2019; KFC-1744-2024The honeybees have been fed by Spirulina platensis extract and algal honey with green color produced by the bees naturally was obtained the first time in order to enhance its medicinal properties, mainly antioxidant properties. Antioxidant capacity, bioaccessibility of phenolics, hydrolysable and extractable phenolics, sugar, phenolic and fatty acid profiles were determined in the Spirulina honey. Total phenolic content of the Spirulina honey was 14.37 mg GAE/100g and increased 28.53% with Spirulina enrichment. Antioxidant capacities of the Spirulina honey were determined as 6.31, 5.85 and 3.66 mu mol Trolox/g by ABTS, CUPRAC and DPPH methods in bioaccessible extracts. No significant difference was observed between control and Spirulina honey samples in terms of bioaccessibility of the total phenolics (p <= 0.01). Among the detected phenolic compounds (15 phenolics), acacetin (48.55%) and pinocembrine (47.13%) were the highest. Total phenolic content of the honey can be enriched up to 20% by feeding of the honey bees with 10% of Spirulina. Saccharose content in Spirulina honey was lower than the control honey as 4.42%.Publication Antioxidant activity and phenolic composition of propolis from Marmara Begion, Turkey(Taylor & Francis Ltd, 2022-12-12) Can, Zehra; Kara, Yakup; Kolaylı, Sevgi; Çakmak, İbrahim; ÇAKMAK, İBRAHİM; Bursa Uludağ Üniversitesi/Ziraat Fakültesi.; 0000-0003-3121-5023; 0000-0002-8000-5770; AAK-5710-2021; AAW-8736-2020This study investigated various properties of raw propolis samples from Marmara region of Turkey. Total phenolic content (TPF), total flavonoid (TFC) values, condensed tannin content (CTC) and phenolic profiles of ethanolic extracts (70%) were analyzed. Antioxidant activities were tested using the Ferric (III) reduction/antioxidant capacity (FRAP) and 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging methods. Phenolic profiles of the samples were analyzed using high performance liquid chromatography (RP-HPLC-UV) method. TPC, TFC and CTC values in the samples ranged from 52.9 to 203.5 mg GAE/g, 13.6 to 43.9 mg QUE/g, and 2.0 and 2.9 mg CTE/g, respectively. Caffeic acid phenyl ester (CAPE), chrysin, pinocembrin, rutin, and t-cinnamic acid were detected as the common phenolic components in all samples. In conclusion, Marmara region propolis is a rich source of bioactive compounds, especially flavonoids with antioxidant properties.Publication The effects of acetamiprid on the motor coordination and sucrose sensitivity of the honey bee, apis mellifera(Oxford Univ Press Inc, 2015-04-01) Young, C.

The natural enrichment method did not cause any negative effects on the quality criteria questioned in the standards such as moisture, pH, free acidity and HMF (Hydroxymethylfurfuraldehyde) content and the quality of the functional honeys obtained was high. Parallel to TPC contents, the antioxidant values of the honeys were increased 5.00-31.50, 16.09-53.96 and 21.18-39.72% by enrichment of orange, pomegranate, and black carrot concentrates. Gallic acid in pomegranate honey (14.52%) and chlorogenic acid in black carrot honey (27.01%) were determined as antioxidant components increased by enrichment. The enrichment process also led to an increase in the bioaccessibility characteristics. The increased antioxidant activity of functional honeys (DPPH) was verified by a high negative correlation value (R =-0.9103) and decreasing IC50 ratios in the opposite direction.Publication An observation study on the effects of queen age on some characteristics of honey bee colonies(Taylor & Francis Ltd, 2008-01-01) Akyol, Ethem; Yeninar, Halil; Korkmaz, Ali; Cakmak, Ibrahim; ÇAKMAK, İBRAHİM; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Zootekni Bölümü.; AAH-2558-2021; AAG-6487-2019This study was conducted to determine the effects of the queen's age on performance of the honeybee (A. mellifera anatoliaca) colonies at nomad beekeeping conditions. Performances of the colonies, which had 0, 1, 2 and 3 year-old queens, were compared. The number of combs, brood areas, wintering ability survival rate and honey yield were determined as performance criteria. The average number of combs with bees throughout the experiment in Group I, Group II, Group III and Group IV was 10.92 +/- 0.78, 14.68 +/- 0.55, 10.10 +/- 0.60, 7.88 +/- 0.45 number combs/colony; the average of brood areas was 3078 +/- 372.5 cm(2), 3668 +/- 460.3 cm(2), 2215 +/- 294.0 cm(2), 1665.38 +/- 241.8 cm(2); the average of wintering ability was 84.3 +/- 2.9%, 88.0 +/- 3.7%, 46.6 +/- 19.0%, 26.8 +/- 16.5%; the survival rate was 100%, 100%, 60%, 40%; and the average of honey yields was 31.4 +/- 1.89 kg, 41.5 +/- 1.05 kg, 20.4 +/- 2.62 kg and 12.0 +/- 1.41 kg per colony, respectively. A significant and negative correlation between queen age and brood production (r=-80.2), colony strength (r=-62.5), wintering ability (r=-66) and honey yield (r=-75.6) were calculated (P<0.01). The colonies headed by young queens had more brood areas, longer worker colony population, better wintering ability and greater honey yield in comparison to colonies headed by old queens.
