Abstract
This study aimed to investigate the effect of heavy metals accumulation in midgut tissues of Enochrus tenuicosta beetles in the Red Sea also in water and sediments of the selected locations. Also to analyze the biochemical response and HSP70 expression. Our results demonstrated that the heavy metals and oxidative stress (MDA) concentrations in the polluted location were higher than the reference one. The response of the antioxidant defense system is significantly higher in the beetles of the reference ones. MT expression and HSP70 were much higher in the polluted beetles than in the reference ones.
