The objective of this study was to predict the future pest scenarios of maize aphid Rhopalosiphum maidis (F.) across six maize growing locations of the India viz., Bhubaneswar (Odisha), Coimbatore (Tamil Nadu), Karimnagar (Telangana), Ludhiana (Punjab), Kanpur (U.P.) and Ranchi (Jharkhand) by using life table parameter data and future climate data. The future data was obtained using Providing Regional Climates for Impacts Studies (PRECIS) A1B model. Among the all locations, lowest intrinsic rate of increase (rm) and finite rate of increase (λ) values were recorded in Coimbatore at elevated CO2 (eCO2) during near future (NF) (0.354 and 1.49 day-1), distant future (DF) (0.306 and 1.43 day-1) compared to that of baseline period. Among the all locations, lowest net reproductive rate (Ro) was recorded in Coimbatore at eCO2 during NF (34.23 and 27.00 nymphs/female), DF (24.97 and 19.34 nymphs/female) and very distant future (VDF) (8.65 and 7.33 nymphs/female) compared to that of baseline period due to decreased range of rm and increased range of temperature. The results showed that increased rm and λ with varied Ro of R. maidis at 6 maize growing regions of India.
