Abstract Plant-herbivore interactions have been extensively studied in tomato plants and their most common pests. Tomato plant chemical defenses, both constitutive inducible, play a role mediating these interactions. Damaged alter volatile profiles, affecting herbivore preferences between undamaged damaged plants. However, previous studies on volatiles yielded conflicting results, the chemistry itself as well attraction/repellent response. This study revisits volatile-mediated two of main herbivores: leafminer Tuta absoluta whitefly Trialeurodes vaporariorum . were analyzed before after damage by each herbivores, preference for oviposition ( T. ) settling was assessed conspecific heterospecific damage. We found that insects consistently preferred over The emission herbivore-induced (HIPVs) increased but decreased While some our findings are line with reports, to oviposit conspecifics, which differs from earlier studies.
