ABSTRACT: Walnuts, along with almonds, cashews, and hazelnuts, are renowned as the world's "four famous nuts," with walnuts being the foremost among them. Walnut fruit is rich in nutrients, including proteins, fats, polyphenols, sugars, phospholipids, melatonin, sterols, flavonoids, iron, zinc, manganese, and other trace elements, as well as dietary fiber. However, the codling moth poses a significant threat to walnut fruits as a major pest. Despite its importance, the transcriptomic changes in walnut husk at different times of codling moth infestation have not been fully explored. In this study, we employed the Illumina NovaSeq 6000 platform to sequence the transcriptome of walnut husk at various time points (0, 12, 24, 36, 48, and 72 hours) after codling moth infestation.
