Effect of (E)-β-ocimene on the choices of P. persimilis between volatiles emitted from plants infested with T. urticae and plants simultaneously infested with T. urticae and B. tabaci, in a Y-tube olfactometer. Choices between odor sources were statistically analyzed with a two-sided binomial test, and choices before and after adding (E)-β-ocimene (indicated by the accolade) was analyzed with GLM, the significance of which is indicated behind the bracket (*, P < 0.05).
