Telenomus remus (Nixon) (Hymenoptera: Scelionidae), is an endoparasitoid on eggs of Spodoptera frugiperda (J. E. Smith). T. remus information as a natural enemy of S. frugiperda is limited. The research objective was to determine some biological aspects of T. remus , i.e., longevity, fecundity, and life table variables. The demographic statistics used the jackknife method. The parasitoids were obtained from the eggs of S. frugiperda from a maize plantation in the field. The released parasitoids were identified in the laboratory. Parasitoid identified as T. remus used to biological observations, life tables, sex ratios, and parasitization rate. The immature stage of T. remus reached 8.13 days, the longevity of the male was 10.07 days, while a female was 10.29 days with a fecundity of 75 eggs, and a sex ratio of male and female was 1:2.03. The life table parameters of T. remus , i.e., gross reproduction rate (GRR) was 74.987 individuals/generation, net reproduction rate (R0) was 67.485 females/female/generation, with generation period (T) was 8.541 days, and intrinsic growth rate (r) was 0.493 females/female/day. The Parasitization rate of T. remus reaches 91%. This research showed that T. remus has the potential natural enemy to control S. frugiperda .
