Fig. 1

The growth inhibitory effects of CPT under different concentrations on S. frugiperda larvae. Average weight of individual larva was presented as mean ± SEM (n = 60). The larvae fed on the artificial diet was used as CK. Treatments were larvae fed on the diet supplemented with different concentrations of CPT. Different capital letters indicate significant differences (p < 0.01) between different doses as determined using ANOVA followed by DMRT
