Eliciting Plant Defenses Through Herbivore-Induced Plant Volatiles’ Exposure in Sweet Peppers

Insect herbivory activates plant defense mechanisms and releases a blend of herbivore-induced volatiles (HIPVs). These volatile compounds may be involved in plant-plant communication induce response undamaged plants. In this work, we investigated whether the exposure sweet pepper plants to HIPVs [ (Z) -3-hexenol, -3-hexenyl acetate, propanoate, butanoate, hexyl methyl salicylate jasmonate] immune system. For this, healthy were individually exposed each above mentioned over 48 h. The expression jasmonic acid salicylic related genes was quantified. Here, show that all tested induced defenses by upregulating signaling pathway. Additionally, Frankliniella occidentalis , key pest, Orius laevigatus main natural enemy F. HIPV-exposed studied Y-tube olfactometer. Only propanoate repelled whereas O. showed strong preference jasmonate. Our results act as elicitors enhancing defensive pathways. We anticipate our starting point for integrating HIPVs-based approaches pest management systems which provide sustainable strategy manage insect pests horticultural
