Abstract:
The experiment was conducted at National Rice Research Institute (NRRI), Cuttack, Odisha under two elevated carbon dioxide concentration i.e. 550ppm & 700ppmCO2 against ambient condition i.e. 410ppm CO2. The study revealed lowest incubation period (5.65±0.22 and 5.80±0.20 days) and adult longevity (2.24±0.17 and 2.30±0.11 days in female, 2.25±0.35 and 2.20±0.20 days in male), highest larval duration (32.25±0.39 and 32.90±0.37 days), pupal duration (7.80±0.27 and 7.95±0.11 days) and total life cycle (48.05±0.67 and 48.95±0.54 days in female, 47.95±0.77 and 48.85±0.57 days in male) were under 700ppm CO2 level against ambient CO2 in atmosphere i.e. highest incubation period (6.50±0.30 and 6.70±0.20 days) and adult longevity (2.80±0.20 and 2.90±0.13 days in female, 2.75±0.30 and 2.65±0.22 days in male), lowest larval duration (26.05±0.48 and 26.15±0.48 days), pupal duration (7.20±0.32 and 7.30±0.11days) and total life cycle (42.55±0.44 and 43.05±0.69 days in female, 42.50±0.55 and 42.80±0.83 days in male) during the RABI 2017-18 and 2018-19 respectively. Similarly the intermediate incubation period, total larval duration, pupal period, adult longevity and total life cycle of S. incertulas were completed in 6.20±0.11 and 6.35±0.13, 28.90±1.06 and 29.15±0.54, 7.65±0.28 and 7.80±0.20, 2.45±0.41 and 2.55±0.11 in case of female, 2.40±0.13 and 2.35±0.13 in case of male, 45.20±1.30 and 45.85±0.51 of female, 45.15±1.16 and 45.65±0.62 days of male under 550ppm CO2 level during RABI 2017-18 and 2018-19 respectively.
