Abstract:
The laboratory experiment was conducted on "Biology of larval parasitoid, Goniozus nephantidis (Muesebeck) (Bethylidae: Hymenoptera)" under South Telangana conditions. Study on the biology of G. nephantidis, revealed that the maximum number of eggs were laid on the on dorso-lateral side on 5th to 6th abdominal segments of Corcyra cephalonica. The incubation period was 2.80±0.50 days. The average egg hatching of G. nephantidis on C. cephalonica was 80.25±7.20 percent. The larval period of G. nephantidis was 3.25±0.68 days. The average precocoon period was 1.55±0.40 days. The cocoon period was 4.90±0.65 days. The average pre-oviposition period, oviposition period and post oviposition period of G. nephantidis were 4.85±0.60, 16.35±2.17 and 2.90±0.56 days, respectively. The average sex ratio (male: female) of G. nephantidis was 1:5.15. The adult emergence of G. nephantidis was 78.85±4.20 percent. The average male and female longevity of G. nephantidis on C. cephalonica was 12.15±0.9 and 23.10±1.25 days, respectively. The average fecundity of G. nephantidis was 47.15±6.45 eggs per female. The total life cycle of male and female was 24.65±4.30 and 35.60±6.50 days, respectively.
