Climate change, especially the rise in temperature and atmospheric carbon dioxide (CO2 ) concentrations, is the major concern of today. The Third IPCC report predicts that global average surface temperature will increase by 1.4 to 5.8o C by 2100 with atmospheric CO2 concentrations expected to rise between 540 to 970 ppm during the same period (Houghton et al., 2001). Effects of elevated atmospheric CO2 on plants are well documented. Elevated CO2 conditions generally result in increased photosynthesis (Drake et al., 1997), increased plant growth (Saxe et al., 1998) and greater biomass (Leadly et al., 1999). Increased carbon levels, decreased nitrogen content and increased C: N ratios were observed in the plants grown under elevated CO2 conditions (Lincoln et al., 1993; Lindroth et al., 1995). The nutritional quality of plants changes under elevated CO2 conditions (Hunter et al., 2001). These changes elicit responses from herbivore insects. Feeding on plants grown in elevated CO2 conditions affects the survival, growth, development and reproduction of insect herbivores. Castor (Ricinus communis L.) is cultivated around the world because of the commercial importance of its oil. India is the world’s largest producer of castor seed and meets most of the global demand for castor oil. India produces 8 to 8.5 lakh tonnes of castor seed annually, and accounting for more than 60% of the entire global production. Because of its unlimited industrial applications, castor oil enjoys tremendous demand world-wide. The current consumption of Castor Oil and its derivatives in the domestic market is estimated at about 300,000 tonnes. India is also the biggest exporter of castor oil and its derivatives at 87% share of the international trade in this commodity. Castor is an important non-edible oilseed crop and is grown especially in arid and semi arid region. It is originated in the tropical belt of both India and Africa. Not Available |
