Impact of eCO2 and Temperature on Aphis craccivora koch. on Groundnut and Future Pest Status During Climate Change Scenarios

Studies were conducted to quantify the direct effects of temperature and indirect effect of elevated CO2 (eCO2), on Aphis craccivora Koch. on groundnut (Arachis hypogaea L.). The mean development time (DT) of nymph was significantly reduced by 1-2 days from 20 to 35°C temperature at eCO2 over ambient CO2 (aCO2) conditions. Increased production of offspring was noticed at eCO2. The thermal requirement of nymph varied from 74-102 DD on eCO2 with temperature in the range of 20-30°C as against 90-130 DD on aCO2. Non-linear mostly quadriatic r... view more»
