Effects of elevated CO2 on the chrysanthemum leaf‐miner, Chromatomyia syngenesiae: a greenhouse study

Abstract

AbstractAlthough feeding behaviour of Chromatomyia syngenesiae on plants grown in elevated CO2 (ambient + 200ppm) was unaffected, leaf‐miner development was slower in elevated compared to ambient CO2 atmospheres. Pupal weight was lower at high CO2 and correlated with the area of leaf mined; no such correlation existed in ambient CO2. There appears to be no compensatory feeding by the leaf‐miner for the reduced food quality of plants growing in elevated CO2. The implications of these findings are discussed.
