Values are after 3 d for leaf disk diets and 5 d for artificial diet. Weights are means ± standard errors in mg. Values followed by different letters for like studies are significantly different at P < 0.05 by Chi square analysis (mortality) or analysis of variance (weights). Values of “bmr” diets in columns for the same experiment followed by a “*” are significantly different from “wild-type” diet values at P < 0.01. See Materials and Methods for phenolic additions that simulate the phenolic acid compositions found in wild-type, bmr6, and bmr12 stalks (Palmer et al. 2008).
