    Abstract:
    The oriental armyworm Mythimna separata is a serious polyphagous pest in China and there are major efforts to control this pest. In the present study, an RNA-Seq method was used to explore transcriptome data of M. separata and identify the responses of genes to chlorantraniliprole. Sequencing and de novo assembly yielded 134,533 transcripts that were further assembled into 77,628 unigenes with an N50 length of 2165 bp. A total of 76 unigenes encoding insecticide targets were identified. Furthermore, 62 cytochrome P450s, 34 glutathione S-transferase (GSTs)and 64 carboxylesterase (CCEs) were curated to construct phylogenetic trees. In addition, we identified 647 the differentially expressed genes following treatment with chlorantraniliprole. The pathways of calcium signaling was identified as response to the pesticide The transcriptome data we generated represents a comprehensive genomic resource for further studies focused on control of M. separata. The response of genes to chlorantraniliprole treatment will elucidate the molecular mechanisms of insecticide resistance and allow for the development of new chemical pesticides to control this pest.
