This study addresses the limited understanding of cotton defense mechanisms triggered by <i>A. suturalis</i> feeding. Utilizing LC-QTOF-MS, we analyzed cotton metabolomic changes induced by <i>A. suturalis</i>, and identified 496 differential positive ions (374 upregulated, 122 downregulated) across 11 categories, such as terpenoids, alkaloids, phenylpropanoids, flavonoids, isoflavones, etc. Subsequent iTRAQ-LC-MS/MS analysis of the cotton proteome revealed 1569 differential proteins enriched in 35 metabolic pathways.
