dc.description.abstract | The information on effects of elevated Carbon dioxide (CO2) and temperature on insect - plant interactions has been compiled and reviewed. Substantial changes in phytochemistry of plants were mentioned by several workers under elevated CO2 conditions. Decreased nitrogen (N) , tremulacin , increased tannin , starch levels led to reduction in nutritional quality in array of plants exposed. To compensate these changes the consumption rate of larvae increased. Differential response was observed among various guilds of insects. In class lnsecta , lepidopterans and homopterans were studied exclusively. Decreased relative growth rate , prolonged development time in lepidciptera cleat' chewers , increased abundance and fecundity in homoptera (sap suckers) were reported. The impact of elevated temperature was mentioned. Human activities have increased the atmospheric concentrations of greenhouse gases and aerosols since the pre - industrial era. Global atmospheric CO2 concentration has increased by approximately 30% since the industrial revolution and is believed to be responsible for an increase of —0.6°C in mean annual global surface temperature (IPCC , 2001). If no climate policy interventions are made , the concentrations of atmospheric CO2 may increase upto 405 - 460 ppm , 445 - 640 ppm and 540 - 970 ppm by 2025 , 2050 and 2100 respectively. It is very likely that 20th century warming contributed significantly to the observed rise in global average sea level and increase in ocean - heat content. Snow covers and ice extent decreased (IPCC , 2001). Apart from the effects mentioned above , agriculture including plants - insect - parasitoid systems is likely to be affected by the climate change. This review summarizes the results from several years of research on the effects of elevated CO2 and temperature on plant chemistry and subsequent effects on the performance of insect herbivores. Effect of elevated CO2 aj Phytochemistry of plants Among the host plants , forest trees and grasses have been extensively studied for insect - plant interactions under elevated CO , (Table 1). Few studies are available on cultivated crops. In majority of studies the elevated CO2 concentrations ranged from 530 ppm to 1050 ppm. Nitrogen concentration decreased in European white birch , Betula pendula (Kuokkanen et al. , 2003) , quaking aspen , Populus tremuloides (Holton et a. , 2003) , condensed tannins increased in european white birch trees (Kuokkanen et a / .. 2003) , quaking aspen (Agra et al. , 2005) , tremulacin levels increased in birch trees (Kopper and Lindroth , 2003) and starch concentration increased in paper birch , Betula papyrifera (Roth and Lindroth , 1995) and pine tree , Pinus taeda (Williams et al. , 1997). As in case of forest trees nitrogen decreased in many of the grasses except annual blue grass in which there was no effect on nitrogen concentration (Bezemer et al. , 1998). In erect brome , Brumus erectus , vernal sedge , Carex caryophylla and Fescue , Festuca sps; increased CO2 resulted in increase in nonstructural carbohydrates and condensed tannins (Goverde et al. , 2002). C:N ratio increased in red fesue , Festuca rubra | en_US |
