Flooding, an under-studied abiotic stressor, creates hostile soil conditions, including hypoxia, which hinder the growth and development of plants. Plants respond to abiotic and biotic stressors. A common response is the production of volatile organic compounds (VOCs), which modulate stress responses and mediate plant and insect interactions. Flooding causes significant losses in crops of agricultural and economic importance including tomato. Understanding how flooding impacts plant growth, plant chemistry, caterpillar performance and chemical mediated plant-herbivore interactions will create fundamental knowledge to an emerging challenge brought about by climate change and inform pest management decisions post flooding events. This study investigated how flooding alters tomato plant volatile emissions and affects caterpillar growth and performance
