BIOLOGY OF THE CORNELIAN, DEUDORIX EPIJARBAS MOORE ON POMEGRANATESajad Mohi-ud-din, A.R. Wani, F.A. Zaki, R.K. Nehru and M.A. SofiAbstract The data generated from the life cycles of two generations of Deudorix epijarbas under laboratory conditions revealed a distinct variation in various developmental stages. The freshly light green eggs, round in shape with flat base were laid either singly or in groups of 2-10. A female laid an average of 24.7±1.88 and 21.3±2.11 eggs in the Ist and 2nd generations, respectively. The incubation period, larval (five instars) and pupal periods were 8.0±0.44, 28.7±1.52 and 9.2±1.00 days, respectively in the 1st generation and 9.8±0.40, 36.9±1.68 and 224.6±1.39 days, respectively in the 2nd generation. The pre-oviposition period, ovipositor period and post-ovipositor period was 3.7±0.48 and 3.9±0.31 days; 3.9±0.31 and 3.4±0.98 days; 5.3±0.82 and 3.5±1.13 days in the Ist and 2nd generations, respectively. The brick red males were smaller in size in wing expanse and shorter in body length than the females. The longevity of male and female was 8.8±1.28 and 12.9±0.96 days in the Ist generation, respectively, while in the 2nd generation it was 7.4±1.04 and 10.8±1.13 days, respectively. The ratio of female: male was 60.32: 39.68 (1.52: 1) during 1st generation and almost the same trend was observed for 2nd generation where in females outnumbered the males with a ratio of 53.84: 46.15 (1.16:1).
