摘要： In this study, the detoxification enzyme activity and the transcriptional profile changes in the second instar through RNA-sequencing technology due to emamectin benzoate (EB) were assessed. The cytochrome P450 monooxygenases (P450) enzyme activity was not altered by EB due to the change in concentration and exposure time in all treatments. The glutathione S-transferase (GST) enzyme was not considerably varying in all treatments, while exposure time significantly changed the enzyme activity. Results showed that the esterase (Ests) activity was elevated with the increasing concentrations and exposure time. Two libraries were generated, containing 107,767,542 and 108,142,289 clean reads for the samples treated with LC30 of EB and control. These reads were grouped into 218,070 transcripts and 38,097 unigenes. A total of 2257 differentially expressed genes (DEGs) were identified from these unigenes, of which 599 up-regulated and 1658 were down-regulated. The majority of these DEGs related to pesticides resistance were identified in numerous Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways, e.g., steroid hormone biosynthesis, glutathione metabolism, drug metabolism-other enzymes, chemical carcinogenesis, pathways of cancer, metabolism of xenobiotics by cytochrome P450, drug metabolism of cytochrome P450, linoleic acid metabolism, retinol metabolism, and insect hormone biosynthesis. These pathways also shared the same genes as cytochrome P450 monooxygenases (P450s), glutathione S-transferases (GSTs), Esterase (Ests), UDP-glucosyltransferases (UGTs), and ATP-binding cassettes (ABCs). A heatmap analysis also showed that regulation of genes in a pathway causes a series of gene expression regulation in subsequent pathways. Our quantitative reverse transcription-PCR (qRT-PCR) results were consistent with the DEG's data of transcriptome analysis. The comprehensive transcriptome sequence resource attained through this study evidence that the EB induces significant modification in enzyme activity and transcriptome profile of Paederus fuscipes, which may enable more significant molecular underpinnings behind the insecticide-resistance mechanism for further investigations.
