| Abstract: | It is well known that sublethal dose of insecticides induces life history trait changes of both target and non-target insect species, however, the underlying mechanisms remain not well understood. In this study, the effects of low concentrations of the anthranilic diamide insecticide chlorantraniliprole on the development and reproduction of the fall armyworm (FAW), Spodoptera frugiperda , were evaluated, and the underlying mechanisms were explored. The results showed that exposure of FAW to LC 10 and LC 30 chlorantraniliprole prolonged the larvae duration, decreased the mean weight of the larvae and pupae, and lowered the pupation rate as well as emergence rate. The fecundity of female adults was also negatively affected by treatment with low concentrations of chlorantraniliprole. Consistently, we found that exposure of FAW to LC 30 chlorantraniliprole downregulated the mRNA expression of juvenile hormone (JH) esterase (SfJHE), leading to the increase of JH titer in larvae. We also found that treatment with low concentrations of chlorantraniliprole suppressed the expression of ribosomal protein S6 kinase1 (SfS6K1) in female adults, resulting in the downregulation of the gene encoding vitellogenin (SfVg). These results provided insights into the mechanisms underlying the effects of low concentrations of insecticides on insect pests, and had applied implications for the control of FAW. [Display omitted] • LC 10 and LC 30 chlorantraniliprole negatively affected the fitness of S. frugiperda. • LC 30 chlorantraniliprole increased the juvenile hormone titer in the larvae. • The mRNA level of SfJHE was downregulated after exposure to LC 30 chlorantraniliprole. • Low concentrations of chlorantraniliprole downregulated SfS6K1 and SfVg.
