Abstract

The tomato leaf miner, Tuta absoluta (Meyrick), is a major agricultural pest with a highly specialized olfactory system that governs host localization, mate selection, and oviposition. Despite the critical role of olfaction in its invasive success, the genome-wide expression of olfactory receptors (ORs) remains poorly understood. This study employs RNA sequencing and transcriptomic analysis to characterize the differential expression of ORs, ionotropic receptors (IRs), and gustatory receptors (GRs) across sensory tissues (antennae vs. maxillary palps), sex (male vs. female), and mating status (virgin vs. mated).These data represents raw and assembled transcriptome sequences for  functional annotation to identify a diverse repertoire of chemosensory receptors in the chemosensory tissues of T. absoluta. By integrating transcriptomic insights with ecological and behavioral contexts, this study provides a foundation for novel, olfaction-based pest management strategies against T. absoluta.
