Data shows germination and appressorial formation rate mean mortality ± SE of 5 replicates 12 h exposure to headspace at 25 °C. The HIPVs was emitted from Aradopsis was induced by different densities of aphids. Means followed by the different letter are significantly different (Tukey’s HSD test, P < 0.05).
