Expression levels of transcripts corresponding to antioxidant response genes in R. arenarum larvae. A, Superoxide dismutase (sod) and catalase (cat) genes. B, GSH-dependent antioxidant response and GSH synthesis genes. Significance levels for Kruskal–Wallis and median tests, *p = 0.09; ¤ p = 0.08; I p = 0.07; **p = 0.01; ***p = 0.003; †††p = 0.0007. AZM azinphosmethyl, CPF chlorpyrifos, at 6 h and 24 h exposures; gene codes are detailed in the text.
