The relative expression of SlGSTd1 and bioassay results of larvae in S. litura after RNAi treatment. (A) The relative expression of SlGSTd1 in S. litura after larvae feeding on dsRNA or H2O. Different lowercase letters indicated significant differences analyzed by ANOVA followed by Tukey's HSD test (P < 0.05). (B–E) Mortality of larvae treated by fenvalerate (B), cyhalothrin (C), beta-cypermethrin (D), chlorpyrifos (E) after feeding on dsRNA. * Indicated significant differences in larvae mortality between feeding on dsSlGSTd1 and dsGFP (student's t-test, P < 0.05).
