Abstract: Demography of Habrobracon hebetor (Say) (Hymenoptera: Braconidae) on two pyralid host species [Galleria mellonella (L.) and Ephestia kuehniella Zeller] (Lepidoptera: Pyralidae) was studied at 28°C in the laboratory. Data were analyzed based on an age-stage, two-sex life table, to take both sexes and variable development into consideration. The intrinsic rate of increase (r), finite rate of increase (lambda), net reproductive rate (R ₀), gross reproductive rate (GRR), and mean generation time (T) of H. hebetor on G. mellonella were 0.1520 d^-1, 1.1640 d^-1, 12.5 offspring, 50.1 offspring, and 16.8 d, respectively. These values were not significantly different from the values obtained for E. kuehniella, i.e., 0.1375 d^-1, 1.1473 d^-1, 11.9 offspring, 54.9 offspring, and 18.2 d. The life expectancy of an H. hebetor egg was 10.6 d on E. kuehniella and 10.4 d on G. mellonella. On both host species, the maximum reproductive value of female H. hebetor occurred on the 12th day.
