Authors:Asena KORKMAZ; Görkem YANIK, Ayhan GÖSTERİT Abstract: Entomopathogenic fungi is one of the biological methods as an alternative to pesticides, which is becoming widespread in greenhouse cultivation. Therefore, it is critical to understand how bumblebees will react to entomopathogenic fungi varieties. In this study, it was determined whether various entomopathogenic fungi (1.5 % Beauveria bassiana strain Bb-1, 1.5 % Lecanicillium lecani strain V1-1, and 1.5 % Paecilomyces fumosoreus strain PFs-1) has effect on food consumption preferences of Bombus terrestris worker. Sugar syrup and pollen consumption amounts, as well as the number of dead workers, were determined for 20 micro colonies with 20 B. terrestris worker on 3rd, 7th, 10th, 14th,17th and 21st control days. Base on the sugar syrup consumption values, it was determined that they consumed the standard one at a similar rate with those containing fungi. In pollen application, it was determined that the consumption of pollen containing L. lecani showed a statistically significant difference only on the 14th control day. In both preference groups, the highest mortality rates were assessed as 13.00 % and 15.50 % on the 3rd control day. In the following control days, mortality rates gradually decreased. The results obtained from the study reveal that entomopathogenic fungi has no significant harmful effect on bumblebees. PubDate: Wed, 28 Dec 2022 00:00:00 +030
Authors:Emre BIÇAKÇI; Mevlüt TÜRK Abstract: This study was carried out in 2018-2020 to determine the forage values of 10 common shrub species (Quercus coccifera, Quercus infectoria, Fraxinus ornus, Fraxinus excelsior, Colutea melanocalyx, Coronilla emerus, Cotoneaster nummularia, Crataegus monogyna, Paliurus spina-christi, Juniperus oxycedrus) in the maquis area around Akkeçili village in Isparta. In the study, dry matter ratio, crude protein ratio (CP), NDF, ADF, total digestible nutrients (TSN), relative feed value (RFV) and tannin ratio were determined seasonally. According to the results of the analysis of variance, the difference between seasons and bush types was found to be statistically very significant in all the examined characteristics.Considering the results obtained on a seasonal basis, the highest CP, TDN and RFV were detected in the spring season, decreased with the progression of the seasons, and the lowest values were determined in the winter season. The lowest dry matter, ADF, NDF and tannin ratios were detected in the spring and increased as the seasons progressed.When the species were compared, the lowest dry matter ratio was found in C. melanocalyx, NDF and ADF ratio in P. Spina-christi and C. melanocalyx, condensed tannin ratio in F. excelsior, F. ornus, C. melanocalyx and C. emerus. The highest CP was obtained from C. emerus, TDN P. spina-christi and RFV C. melanocalyx species. As a result, it has been determined that the shrub, shrub-shaped tree and shrub species in the maquis have the potential to produce quality feed for ruminants in the critical period in semi-arid and arid regions.

Authors:Fahriye UMUT; Şengül BİLGİN, Levent İZCİ Abstract: The immune system is responsible for protecting the host from threaten against pathogenic microorganisms. A well immune system provides defense against pathogenic organisms and gives resistance with food components. Malnutrition weakens the immune system and makes the individual more susceptible to infection. In nutrition, seafoods have an important in human nutrition and its contribution to the immune system due to the nutritional components it contains. Seafoods and especially fish; polyunsaturated fatty acids (such as omega-3), immunomodulatory amino acids such as melatonin, tryptophan, taurine and polyamines, fat-soluble vitamins A, D and E, water-soluble vitamins B6 and B12 and selenium, phosphorus, calcium and zinc to strengthen immunity contains important minerals. Carotenoids, which are abundant in shellfish, are important compounds in that they are precursors of vitamin A and thus participate in the body defense system. In this study were investigated the effects of seafood nutritional components on the immune system. PubDate: Wed, 28 Dec 2022 00:00:00 +030

Authors:Cuma Nur KILIÇ; Adnan YILDIRIM, Civan ÇELİK Abstract: This study aimed to determine the phenological developments and fruit quality characteristics of some persimmon (Fuyu, Hachiya, Hanna Fuyu, and Rojo Brillante) cultivars grown in the Denizli province. For this purpose, phenological developmental periods such as bud burst, the beginning of flowering, full flowering, end of flowering, and front of harvest, and tree development characteristics such as crown height, crown width, trunk diameter, and the number of primary branches were determined. In addition to these, differences in terms of pomological and chemical properties between cultivars were revealed. In the study, it was determined that all cultivars performed the bud burst stage in April and reached the full flowering period in May. Five months after full bloom, that is, in October, all cultivars were harvested. In terms of tree characteristics, the Hanna Fuyu cultivar, which showed the strongest growth among persimmon cultivars, was the lowest Fuyu cultivar. In terms of fruit characteristics, it was determined that the largest fruits belonged to the Hachiya cultivar. As a result of the analyzes made in the fruit juices of persimmons, it was determined that the amount of TSS varied between 20% and 13%, the pH value varied between 5.9% and 5.64%, and TA between 0.14% and 0.28%. As a result, it was determined that all of the persimmon cultivars specified in the study were suitable for cultivation in the Denizli province in terms of flower formation, phenological development periods, and fruit quality.
