Effect of elevated CO2 and temperature on leaf damage caused by S. litura and infestation of green peach aphid, Myzus persicae Sulzer in bell pepper

Meena Kumari and Subhash Chander Verma

Rising level of atmospheric CO2 as a result of increasing emissions will affect the plant foliage quantity as well as quality, which could result in greater effect on the life cycle of insect herbivores. So the field experiment was conducted during 2014 and 2015 to study the effect of elevated CO2 and temperature on per cent leaf damage caused by S. Litura and infestation caused by Myzus persicae to bell pepper plants grown under four concentrations of CO2 and temperature, viz. three Open Top Chambers, (T1: OTC with elevated CO2 550±10 ppm; T2: OTC with elevated temperature 1°C higher and elevated CO2 550±10 ppm; T3: OTC with ambient temperature and CO2 (reference) as well as under T4: natural ambient air and temperature in open. Biochemical analysis of foliage revealed that plants grown under elevated CO2 had lower nitrogen which caused an increase in food consumption by S. litura in order to compensate their nutritional requirement and hence resulted in more infestation as compared to ambient CO2 and temperature and natural condition. Also elevated CO2 and temperature resulted higher number of aphids on bell pepper plants which may be due to elevated CO2 and temperature which favours better growth of aphids under denser plant canopy and humid conditions.
