Insect growth regulators are mostly used in pest management since they are non toxic to other organisms and have short half life in the environment. Effects of juvenile hormone analogue, pyriproxyfen on catalse (CAT) and superoxide dismustase (SOD) activity of Galleria mellonella was investigated. Larvae were exposed to 0.0001; 0.0005; 0.001 and 0.005 mg/ml of pyriproxyfen for 24, 48 and 72 h and CAT and SOD activities were measured spectrophotometrically after treatment. Significant increases in CAT and SOD, activity were observed in larvae exposed to 0.0005; 0.001 and 0.005 mg/ml pyriproxyfen for 24, 48 and 72 h. Changes in the activities of SOD and CAT after the juvenile hormone analogue application suggested that exposure to pyriproxyfen induced oxidative stress.
