Increased presence of benzo[a]pyrene in the environment underlines need for development sensitive biomarkers monitoring. Antioxidative enzymes could be used as early-warning signals because their sensitivity and applicability. The activity 2 antioxidative enzymes, superoxide dismutase (SOD) catalase (CAT), were measured midgut tissues fifth instar Lymantria dispar larvae exposed to different concentrations benzo[a]pyrene: ng, 10 20 100 200 2000 ng benzo[a]pyrene/g dry food weight. Larval development, larval mass, relative growth rate also monitored. authors detected prolonged well reduced mass all concentrations. L. SOD was significantly increased, isoforms on native polyacrylamide gel electrophoresis fed artificial diet supplemented with benzo[a]pyrene. In contrast, control group had only 1 isoform. Catalase increased benzo[a]pyrene-treated larvae. Native showed that a switch active CAT occurred after treatment. Thus, polyphagous herbivorous are very low Therefore, they exposure effects this toxic polycyclic aromatic hydrocarbon.
