  1. Specific activities of antioxidant enzymes in different field populations of T. castaneum. The values of mean ± standard error followed by distinct letters are significantly different (p < 0.05). One unit of SOD is defined as the amount of enzyme needed to exhibit 50% dismutation of the superoxide radical. The treatment means were separated by Duncan’s multiple range test. Three replications of each enzyme (catalase, peroxidase, and SOD) were carried out to determine the activity presented in the table.
