Exposure to E,S-conophthorin enhances jasmonic acid induction in S. altissima. T. virgata feeding damage induced significantly more JA in plants exposed to the E. solidaginis emission blend or the most abundant compound in the blend, E,S-conophthorin, compared to solvent controls. S. altissima exposed to the second most abundant compound, 1-nonanol, induced a similar amount of JA to control plants. Plants exposed to a racemic mix of (2E) and (2Z)-2-methyl-1,6-dioxaspiro[4.5]decane had an intermediate JA induction (ANOVA F 4,25 = 13.2, P = 0.0002, n = 6). Data shown are not transformed but statistical analyses were performed on square-root-transformed data. Bars marked with different letter indicates significant differences (Tukey post hoc test, P ≤ 0.05). Error bars correspond to standard errors
