Investigations were made to predict the impact of increase in temperature on number of generations of S. litura on peanut for four locations of India viz., Dharwad (15° 28’ N, 75° 2’ E); Junagadh (21° 31’ N, 70° 36’ E); Ananthapur (14° 62’ N, 77° 65’ E) and Vridhachalam (11° 3’ N, 79° 26’ E) for baseline (1961-1990), present (1991-2005), near future (2021- 2050) and distant future (2071-2098) climate change (A1B) scenarios. Higher accumulation of degree days making it possible one or two additional generations of S. litura was inferred for both near and distant-future climate change scenarios compared to baseline and present periods, at four locations. The mean generation time under baseline (41 days) and present (36 days) periods, lasted longer over the near future (35 days) and distant future (31 days) scenarios at Dharwad. It is also predicted that the completion of generation would be 5-6 days earlier during future climatic scenarios than the current period at other locations. The additional number of generations and the variations in the generation time of S. litura imply definitive and differential impacts, respectively of the projected increasing temperature in future periods Not Available |
