Abstract

Field and laboratory experiments were carried out to clarify the effects of different cucumber cultivars (Ghazeer, Melouky, and Zeen) secondary metabolites on antioxidant enzymes of whitefly, Bemisia tabaci (Gen.), catalase, CAT, and superoxide dismutase (SOD). Results showed that the antioxidants enzyms, CAT and SOD were found to be increased in the cultivar Melouky, which had a high content of plant secondary metabolites. Also, results showed that increasing levels of plant secondary metabolites tend to increase B. tabaci CAT and SOD levels.
