Abstract
P. japonica prefers damaged leaves grown under elevated CO2 over damaged leaves grown under ambient CO2, which may be the result of increased complexity in volatile compounds in leaves grown under elevated CO2. Increased amounts of flavonols and decreased amounts of isoflavonoids in leaves grown under elevated CO2 may contribute to increased herbivore longevity and fecundity. A. glycines population growth is greater on soybeans grown under elevated levels of CO2, which may be the result of increased leaf temperatures. V. cardui larval development and mortality are not changed when caterpillars fed on soybean leaves grown under elevated levels of CO2, which may be the result of nitrogen fixation and consequent nitrogen enrichment in soybean foliage.
