Abstract

Tarımsal alanlarda ve depolanan ürünlerde zararlı böcekler ile mücadele amacıyla kullanılan kimyasal pestisitlerin uygulamalarının azaltılması önemli bir olgudur. Bununla birlikte, çevre dostu biyopestisitler zararlı kontrol programlarının yönetiminde diğer sentetik kimyasalların olumsuz etkilerinin üstesinden gelmek için önemli hale gelmiştir. Bu çalışmada, önemli bir fitokimyasal bileşik olan Juglonun Galleria mellonella larvalarında neden olduğu oksidatif stres değişiklikleri incelenmiştir. Bu amaçla, juglonun etkili konsantrasyonları (LC10: 0.5 mg; LC30: 1.5 mg; LC50: 2.3 mg) birinci evre larvaların 2 gram besini içerisine ilave edildi. Son dönem larvaların hemolenf örnekleri, antioksidan enzim aktivitesi (glutatyon peroksidazlar - GPx, glutatyon-S transferaz - GST, katalaz - CAT ve süperoksit dismutaz - SOD) ve malondialdehit (MDA) testlerinin analizlerinde kullanıldı. Besinsel juglona maruz kalan son dönem G. mellonella larvalarının hemolenfinde antioksidan enzim aktiviteleri (SOD, CAT ve GST) ve MDA miktarı kontrol larvalarıyla karşılaştırıldığında doza bağlı olarak değişmiştir. Bununla birlikte, uygulama yapılan ve yapılmayan larvalara ait GPx enzim aktivitesinde değişiklik belirlenmedi. Sonuç olarak, juglonun etkili dozları model ve zararlı böcek G. mellonella için toksiktir.

Abstract

Reducing the usage of chemical pesticides used to control pests in agriculture and stored products is an important phenomenon. Also, eco-friendly biopesticides have become highly important for use in the management of the pest control programs to overcome the negative influences of other synthetic chemicals. In this study oxidative stress changes induced by one important phytochemical compound, juglone, in Galleria mellonella larvae were investigated. For this purpose, effective concentrations (LC10: 0.5 mg; LC30: 1.5 mg; LC50: 2.3 mg) of juglone were added into the 2 g diet of the first instar larvae. Hemolymph samples from the last instar larvae were used to analyses of antioxidant enzyme activity (glutathione peroxidases – GPx, glutathione-S transferase - GST, catalase - CAT, and superoxide dismutase - SOD) and malondialdehyde (MDA) assays. Activities of antioxidant enzymes (SOD, CAT, and GST) and MDA level in the hemolymph of last instar G. mellonella larvae exposed to dietary juglone changed dose-dependently when compared to the control larvae. However, there was no change detected in GPx enzyme activity in both treated and untreated larvae. Consequently, effective doses of juglone are toxic to the model and pest insect G. mellonella.
