Abstract

The present study aims to investigate the effectiveness of various tea extracts in providing ultraviolet (UV) protection for entomopathogenic fungi. UV radiation could have detrimental effects on viability of these fungi, which are important biocontrol agents against insect pests. This study was carried out in the Microbiology Laboratory of the Department of Biology Karadeniz Technical University in 2023. We evaluated the UV protective properties of various tea extracts in entomopathogenic fungi [Beauveria bassiana (Bals.) Vuil. (Hypocreales: Cordycipitaceae) and Metharizium flavoviride (Gams and Rozsypal 1956) (Hypocreales: Clavicipitaceae)] and tea extracts effectiveness against Galleria mellonella (L.,1758) (Lepidoptera: Pyralidae) larvae. Our findings demonstrate that certain tea extracts exhibit significant UV protection for entomopathogenic fungi, suggesting their potential application in improving the performance of biocontrol agents in outdoor environments. The highest UV-B protection was observed by adding black and green tea extracts to fungal spores, resulting in a radial growth measurement of 14.6 mm and 14.3 mm, respectively, at the end of 10 days of exposure for 120 minutes. These results contribute to the development of eco-friendly strategies for pest management in agriculture.

茶提取物对昆虫病原真菌孢子的紫外线防护性能及其对大蜡蚧(L.， 1758)的杀伤作用(鳞翅目:蚜科)

本研究旨在探讨不同茶叶提取物对昆虫病原真菌的紫外线防护效果。紫外线辐射可能对这些真菌的生存能力产生不利影响，而真菌是重要的害虫生物防治剂。本研究于2023年在卡拉德尼兹技术大学生物系微生物实验室进行。研究了不同茶叶提取物对球孢白僵菌(Beauveria bassiana, Bals.)的紫外线防护性能。Vuil。(下翅目:冬虫夏草科)和黄毒甲醚(Gams and Rozsypal 1956)(下翅目:蛾蚜科)]和茶提取物对mellonella (L.，1758)(鳞翅目:蛾蚜科)幼虫的有效性。我们的研究结果表明，某些茶叶提取物对昆虫病原真菌具有显著的紫外线保护作用，这表明它们在改善室外环境中生物防治剂的性能方面具有潜在的应用前景。将红茶和绿茶提取物添加到真菌孢子中观察到最高的UV-B保护，在暴露120分钟的10天结束时，径向生长测量分别为14.6 mm和14.3 mm。这些结果有助于制定农业有害生物管理的生态友好战略。

期刊介绍： The Turkish Journal of Entomology is a quarterly journal which has been published by Entomological Society. Turkish Journal of Entomology publishes original research articles in the fields of entomology and agricultural zoology in English. Authors whose native language is not English should have their paper edited professionally prior to submission. Before preparing the typescript for submission, examine the format of manuscripts already published in Turkish Journal of Entomology. According to TJE rules, biological observations made in one location in only one-year, short notes in which the first record of a single species in Turkey is announced, and research which is older than five years will not be accepted for publication unless it forms part of a longitudinal study.
