Expected number of generations of Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae), a polyphagous pest on several agricultural and horticultural crops was assessed for both the present and future climate change scenario (A1B) for India using CLIMEX, a bioclimatic modeling software. Predictions were done for two future time frames (2030 and 2080) as projected by Intergovernmental Panel on Climate Change (IPCC). The pest is expected to attain one or two additional generations in most parts of the country by 2080 compared to the base year (1975). A tukey’s test indicated that the number of generations are lower in baseline (10.6 ± 0.67) compared to the predicted scenarios in 2030 (11.5 ± 0.68) and 2080 (12.7 ± 0.68) time frames. There was statistically significant differences between number of generations during baseline compared with 2030 (p = 0.014) and 2080 (p = 0.000) and between 2030 and 2080 time frames (p = 0.001). The present findings were validated using available literature regarding number of generations possible for the pest.
