[Objective] In this study, the transcriptome database of Apocheima cinerarius was established to annotate the functions of these genes and excavate olfactory related genes, aiming at exploring the phylogenetic relationship of olfactory sensory mechanism of A. cinerarius to-lay a molecular foundation for further of olfactory sensory mechanism of A. cinerarius, and it will be provide molecular informatics foundation for effective prevention and control of the insect [Method] With the aid of using new generation of high-throughput sequencing platform (Illumina HiSeqTM 2500) methords, we performed transcriptional profiling for male and female adults of A. cinerarius. After data assembly, olfactory related genes were screened, and the sequencing results were analyzed by genes clustering and functional annotation. [Result] 37 542 Unigenes were assembled from the transcriptome database( https :/ / www. ncbi. nlm. nih. gov/ search/all? term = PRJNA648143 ), and a total of 17 296 Unigenes were annotated by comparing the transcriptome data with the public database, these unigenes were 16. 3 % similar to Spoiklptera litura which is the most alike. 11 174 U nigenes were distributed in 55 functional groups in the GO database, including the three categories of cell components, molecular functions and biological processes. KEGG analysis results showed that a total of 5444 Unigenes formed 230 metabolic pathways. The combination of gene annotation information and blastp verified a total of 70 olfactory related genes, including 22 Odorant binding proteins (OBPs),23 Chemosensory proteins ( CSPs ),and 14 Odorant receptors (ORs) (including 13 Ordinary receptorsand 1 ORco), 8 lonotropic receptor( IRs) and 3 Sensory neuron membrane proteins (SNMPs). The phylogenetic tree of 96 CSPs constructed with Ectropis oblique, Semiothisa cinerearia, Bombyx mori, Ostrinia furnacalis and the other four insects showed that A. cinerarius and E. oblique formed a clear orthologous pedigree, and a total of 9 pairs of CSPs were clustered in the same phylogenetic treebranch. [Conclusion] In this study, the transcriptome data of A. cinerarius adult was established for the first time, olfactory-related genes were identified, and investigated the phylogenetic evolution of the identified genes. These results provided basic molecular for the function research and olfactory recognition mechanism of A. cinerarius. [ABSTRACT FROM AUTHOR]
