In this study the effect of long term exposure to cadmium (Cd) on Ostrinia nubilalis larval growth, development, survival rate and oxidative status was analyzed. Newly hatched first instar - L1 larvae were reared on a Cd contaminated diet until the larvae reached the final, fifth instar - L5 or developed into pupae. In total, six experimental groups, five treatments (concentrations of Cd in fresh diet: Cd I: 0.73, Cd II: 3.70, Cd III: 6.85, Cd IV: 41.71 and Cd V: 77.53 mg kg-1) and a control group (C) were set up. The results of the experiment showed that exposure to higher concentrations of Cd (41.71 and 77.53 mg kg-1) had a significant influence on development and redox status of O. nubilalis larvae: (1) the development rate was strongly reduced resulting in a prolonged pupation time; (2) the survival rate of larvae was prominently lower; (3) bioaccumulation factor (measured in pupae) was reduced which indicated that larvae could accumulate Cd to a certain level; (4) the level of the lipid peroxidation was significantly higher, which points to oxidative damage; (5) the expression of Mtn was significantly up-regulated while Cat and GPx genes down-regulated. In conclusion, long term exposure to dietary Cd in a concentration of 41.7 mg kg-1 and higher, induced oxidative stress and slowed down growth and development of O. nubilalis larvae.
