Biology, Age Specific Fecundity and Intrinsic Rate of Increase of Goniozus triangulifer Kieffer (Hymenoptera:Bethylidae), a Larval Parasitoid of Rice Leaffolder, Cnaphalocrocis medinalis (Guenee) (Lepidoptera:Pyralidae)
Biology of Goniozus triangulifer Kieffer (Hymenoptera :Â Bethylidae) on Cnaphalocrocis medinalis (Guenee) revealed the egg-larvalÂ period to be 9.05Â±1.14 days, pupal period 3.65Â±0.48 days and adultÂ longevity 8.30Â±1.26 days for males and 11.10Â±1.77 days for females. SexÂ ratio was 1:4.30 (M:F). Life table data of the parasitoid indicated that theÂ ovipositing females lived for a maximum of 9 days and increased itsÂ population at the rate of 16.40 per generation (R0) with mean generationÂ time (Tc) of 14.61 days. The intrinsic rate of natural increase (rm) was 0.193Â and the finite rate of increase (Î») was 1.212 females/female/day.
