Changes in melon plant phytochemistry impair Aphis gossypii growth and weight under elevated CO₂.

ABSTRACT: Elevated CO₂ (eCO₂) modifies plant primary and secondary metabolism that subsequently impacts herbivore insect performance due to changes in its nutritional requirements. This laboratory study evaluated interactions between Aphis gossypii Glover (Hemiptera: Aphididae) and melon (Cucumis melo L., Cucurbitaceae), previously acclimated two or six weeks to different CO₂ levels, eCO₂ (700 ppm) or ambient CO₂ (400 ppm). Under eCO₂, melon plants decreased nitrogen foliar concentration and increased carbon to nitrogen ratio, independently of acclimation period, significantly reducing the content of some amino acids (alanine, asparagine, glycine, isoleucine, lysine, serine, threonine, and valine) and increasing the carbohydrate (sucr
