BACKGROUND As the largest transporter gene family in metazoans, ATP‐binding cassette (ABC) transporters regulate the efflux of a broad spectrum of substrates from the cytoplasm to the outside of the cell. In arthropods, ABC transporters are involved in phase III of the detoxification process, and play important roles in the metabolism and transport of insecticides. RESULTS We identified 54 ABC transporters from the genome and transcriptome of Chilo suppressalis , one of the most damaging pests of rice in China. The identified ABC transporters were classified into eight subfamilies (ABCA to ABCH) based on NCBI BLAST and phylogenetic analysis. Synergism studies showed that treatment with verapamil, a potent inhibitor of ABC transporters, resulted in significantly increased toxicity of chlorantraniliprole against C. suppressalis larvae. Among the 21 tested ABC genes, three ABC transporter genes including CsABCC8 , CsABCG1C and CsABCH1 were significantly upregulated after chlorantraniliprole treatment. CONCLUSION ABC transporters play important roles in the detoxification and transport of chlorantraniliprole in C. suppressalis . The results from our study provide valuable information on C. suppressalis ABC transporters, and are helpful in understanding the roles of ABC transporters in chlorantraniliprole resistance mechanisms in C. suppressalis and other insect pests. © 2020 Society of Chemical Industry
