The egg-larval and pupal periods of Apanteles cypris Nixon (Hymenoptera: Braconidae), a larval parasitoid of Cnaphalocrocis medina lis (Guenee) were 0.90±0.72 and 3.70±0.73 days, respectively. Longevity of male and female were 4.1±0.71 and 3.95±0.82 days, respectively. Male:female ratio was 1: 1.8. Life table data of the parasitoid indicated that the ovipositing females lived for maximum six days and they increased their population at the rate of 30.97 per generation (Ro) with mean generation time(Tc) of 14.01 days. The intrinsic rate of natural increase (rm) was 0.249 and the finite rate of increase (λ) was 1.282 females/female/day.
