摘要： Cyantraniliprole is a novel anthranilic diamide insecticide commonly used against fall armyworm, Spodoptera frugiperda; however, sublethal exposure of cyantraniliprole on different generations of S. frugiperda, has not been fully studied. This proposed study aimed to estimate the sublethal effects of cyantraniliprole on the biological and demographic parameters of parental generation (F-0) and intergenerational effects on the offspring generation (F-1) of S. frugiperda using Age-stage, two-sex life table software. The bioassay result proved the strong toxicity of cyantraniliprole toward S. frugiperda, as demonstrated by an LC50 value of 0.439 mg/kg after 96 h treatment. The larval duration of F-0 S. frugiperda significantly increased when treated with the low lethal (LC30) and sublethal (LC10) concentrations of cyantraniliprole. Adult longevities were decreased while pupal duration was increased in the treated groups. The adult preoviposition period (APOP) and total preoviposition period (TPOP) were higher in the treated groups compared to the control. Moreover, the fecundity was significantly decreased at the LC10 and LC30 in the F-0 and F-1 generations, respectively. For the F-0 generation, the relative fitness (R-f) for the LC10 and LC30 were 0.45 and 0.32, while for the F-1 generation, the values were 0.65 and 0.48, respectively. In summary, our results showed that life table characteristics of S. frugiperda were negatively affected by LC10 and LC30 of cyantraniliprole, ultimately inhibiting population growth. These findings may be crucial for understanding the overall impact of cyantraniliprole on the life-history traits of S. frugiperda, potentially aiding in the management of this invasive pest in open-field conditions.
