摘要： Background The fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), is an aggressive pest species that causes severe economic losses in outbreak regions. Use of FAW natural enemies, particularly native parasitoids, has been suggested as a promising control strategy. Campoletis chlorideae Uchida (Hymenoptera: Ichneumonidae) is a solitary ichneumonid larval endoparasitoid with a broad host range that includes S. frugiperda. However, its parasitism rate, developmental stages, and population dynamics during parasitization of S. frugiperda remain unclear. A field survey was conducted to determine the emergence rate and sex ratio of C. chlorideae, evaluated the biological control performance, and investigated the production potential of it on the individually reared and group-reared S. frugiperda through age-stage, two-sex life tables, respectively. Results The results showed that C. chlorideae parasitizing individually reared FAW resulted for the parasitoid in a lifetime total fecundity (F) of 301.5 +/- 16.4 eggs/female, a net reproduction rate (R0) of 62.03 +/- 9.07 adult females/female, an overall life span of females of 28.3 +/- 0.52 days, and an intrinsic rate of increase (r) of 0.1946 +/- 0.0076 day-1. In contrast, the parameters of F, R0, overall life span of females, and r were 87.71 +/- 6.32 pupae/female, 6.02 +/- 1.61 adult females/female, 25.21 +/- 0.79 days, and 0.0918 +/- 0.0148 day-1 in group-reared S. frugiperda. Conclusions This study suggests that C. chlorideae has a promising biological control potential against S. frugiperda. Future research should focus on developing methods to increase the production of C. chlorideae.
