HDMBOA-Glc Reduces Aphid Performance in Vitro More Strongly Than DIMBOA-Glc.

(A) Aphid progeny production on diet with benzoxazinoids. Progeny per adult aphid were counted after 2 d on diet containing the indicated concentrations of DIMBOA-Glc and HDMBOA-Glc (mean ± se; n = 6; n = 12 for controls). Asterisks indicate significant differences (*P < 0.05, Dunnett’s test relative to control samples).

(B) Adult aphid survival on diet with benzoxazinoids. Diet contained no benzoxazinoids (control; diamonds), 2 mM DIMBOA-Glc (squares), or 2 mM HDMBOA-Glc (triangles) (mean ± se; n = 6; n = 12 for controls). Asterisks indicate significant differences (*P < 0.05, Dunnett’s test relative to control samples).
