Enzymes specific activity 96 h. post-treatments with LC25 of Spinetoram (Sp), LC25 of Methoxyfenozide (M), or LC25: LC25 values of M + Sp on the susceptible (SUS) and resistance (MS) strains of Spodoptera littoralis, respectively. (A), and (B): α-esterase activity, (C) and (D): GST activity, and (E) and (F): Monooxygenase activity. Values represent mean ± standard error. Means followed by different letters are significantly different according to Tukey’s multiple range comparison (P < 0.01). F-ratio and p-values are calculated with ANOVA analysis.
