(A) Declining trend of L-DOPA concentrations after Acyrthosiphon pisum on Vicia faba were transferred into an artificial diet and the last bar represents the L-DOPA concentrations in A. pisum fed on Trifolium Repens. (B) Relative transcript levels of TH from the aphids were reared on V. faba and the artificial diet; and (C) Relative transcript levels of TH from the aphids were reared on T. repens and the artificial diet. Each value represents the mean ± SEM.
