Deciphering the Olfactory Mechanisms of <i>Sitotroga cerealella</i> Olivier (Lepidoptera: <i>Gelechiidae</i>): Insights from Transcriptome Analysis and Molecular Docking.

ABSTRACT: Olfaction is crucial for insect activities such as host seeking, foraging, oviposition, and predator avoidance. While olfactory proteins have been identified across several insect species, their specific functions are largely enigmatic. In this study, we investigated the olfactory proteins of the Angoumois grain moth, Sitotroga cerealella Olivier. A total of 165 presumptive olfactory genes were identified in the antennal transcriptome of S. cerealella, encompassing 33 odorant-binding proteins (OBPs), 10 chemosensory proteins (CSPs), 58 odorant receptors (ORs), 41 ionotropic receptors (IRs), 21 gustatory receptors (GRs), and 2 sensory neuron membrane proteins (SNMPs). BLASTX and a phylogenetic analysis showed a high similarity of these genes to the orthologs in other model ins
