Table S1. Areas for ions [named by retention time/ mass- to-charge ratio (m/z)] detected in each inbred-treatment combination. Inbreds EP42 and PB130 are considered susceptible and resistant to attack by Sesamia nonagrioides , respectively. Treatments applied were: No treatment (Control), 9-day feeding bySesamia nonagrioides larvae (D9) and 2-day by Sesamia nonagrioides larvae (D2)
Table S2. Ions with a VIP (variable importance in projection) score > 2 in the PLS‐DA model for the long-term response (control vs 9-day infestation with MCB) in one inbred or in both inbreds (PB130 and EP42 considered as resistant and susceptible, respectively). The formula and name of metabolites identified as long as those PLS-DA models in which the feature shoes a VIP score > 2 are also presented
Figure S1. Greenhouse experiment design, * maize samples for establishment of the bioassay and metabolite characterization were taken 77 days after sowing in the earliest planting. Maize tissues from the second and third plantings were taken at 84 and 91 days, respectively, to renew feeds for MCB larvae.
