  1. Least square (LS) mean values of larval weight (mg) of MCB larvae fed on leaves from maize plants pre-infested with MCB larvae, wounded, treated with MCB regurgitant upon wounding, exposed to methyl jasmonate (MeJA) or untreated (control). Bioassays were initiated 2 days after treatment (dat)
  2. aWithin each column, different letters indicate significant differences (p < 0.05)
