L-DOPA contents in Vicia faba and Trifolium repens (A) and L-DOPA (B) dopamine (C) contents in Acyrthosiphon pisum reared separately on V. faba and T. repens; L-DOPA concentrations in phloem of V. faba were detected and shown in (D) L-DOPA amounts in leaves of V. faba were extracted by grinding as a positive control; survival rate of aphids treated with L-DOPA (20 mM) by feeding artificial diets. Survival rate of A. pisim fed on T. repens (nAD = 150, nDOPA = 150) was shown in (E) Survival rate of A. pisim fed on V. faba (nAD = 150, nDOPA = 150) was shown in (F).
