Selenium prevents thrips herbivory to S. pinnata in both choice and non-choice studies. A: Choice feeding experiment quantifying thrips herbivory of S. pinnata plants treated with or without Se, quantified as percentage of leaves per plant showing herbivory. B: Selenium concentration in plants treated with Se, comparing leaves that experienced thrips herbivory with leaves showing no herbivory. C: Elemental concentration of Fe, Mg, Mn, Mo, S and Zn in plants treated with Se, comparing leaves that experienced thrips herbivory with leaves showing no herbivory. Values are means +/- SE. An asterisk between a pair of bars represents a significant difference between the two treatments (t-tests, α = 0.05, n = 18).
