From: The timing of herbivore-induced volatile emission in black poplar (Populus nigra) and the influence of herbivore age and identity affect the value of individual volatiles as cues for herbivore enemies

Figure 4

Effect of feeding intensity during various herbivory treatments on volatile emission of Populus nigra compounds. P values indicate significant differences after applying a GLS model (excluding the effect of herbivore identity). p < 0.001 = ***, p < 0.05 = *, n.s. = not significant. Herbivory treatments are depicted by different symbols.
