摘要： Simple Summary: The loreyi leafworm, Mythimna loreyi (Duponchel), has recently expanded its distribution range to many countries around the world. To understand the molecular response mechanism of this pest to cold stress, a comprehensive transcriptome analysis was carried out in three developmental stages (larvae, pupae, and adults) of M. loreyi. The results indicated that there were significant differences in metabolism-related processes and gene expression when they were exposed to low temperatures. In addition, several differentially expressed genes were identified in these stages after exposure to cold stress. This is the first study to test cold stress-induced transcriptional changes in three developmental stages of M. loreyi and provide basic data for understanding the molecular response mechanisms of moths under cold stress. The loreyi leafworm Mythimna loreyi (Lepidoptera: Noctuidae) is a serious pest of agriculture that causes particular damage to Gramineae crops in Asia, Europe, Australia, Africa, and the Middle East. Low temperature is one of the important environmental factors that limits the survival, distribution, colonization, and abundance of M. loreyi. However, the metabolic synthesis pathways of cold-tolerant substances in M. loreyi and the key genes involved in the regulation under cold stress remain largely unknown. In this study, we sequenced the transcriptomes of three developmental stages (larvae, pupae, and adults) of M. loreyi to discover the molecular mechanisms of their responses to cold stress. In total, sequencing generated 120.64 GB of clean data from 18 samples, of which 19,459 genes and 1740 differentially expressed genes (DEGs) were identified. The enrichment analysis of Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) revealed that many DEGs were mainly enriched in pathways associated with energy metabolism and hormone metabolism. Among these, genes encoding multiple metabolic enzymes, cuticle proteins (CPs), and heat shock proteins (HSPs) were differentially expressed. These results indicate that there are significant differences among the three developmental stages of M. loreyi exposed to cold stress and provide a basis for further studying the molecular mechanisms of cold tolerance in insects.
