Bionomics of rice moth, Corcyra cephalonica (st.) on groundnut variety TG – 37

Aparna K Menge, Kumud V Naik, VN Jalgaonkar and GM Golvankar

The bionomics of Corcyra cephalonica (St.) was studied under controlled conditions (temperature 28 ± 2.33º C and relative humidity 64 ± 6.30%) in the laboratory. The seed material of the commonly cultivated groundnut varieties in Konkan region i.e. TG - 37 was selected for the present investigation. The average 345 eggs were deposited by the female moth emerged from variety TG - 37. Average oviposition period, incubation period and hatching percentage were 3.90 days, 4.50 days and 94.33 per cent, respectively. Average larval and pupal period were 41.10 days and 10.70 days. The total development period was 53.90 days. The average weight, length and breadth of larva on TG - 37 were 30.00 mg, 12.00 mm and 1.60 mm, respectively, while average weight, length and breadth of pupa were 26.93 mg, 8.50 mm and 1.80 mm, respectively. The average weight, length and wingspan of adult male were 14.49 mg, 7.00 mm and 14.90 mm, respectively, while it was 20.54 mg, 9.20 mm and 16.25 mm in female moth. The average longevity of male and female was 8.40 days and 7.00 days, while the sex ratio of rice moth was 1:1.11.
