摘要： The aphid complex (Brevicoryne brassicae, Lipaphis erysimi and Myzus persicae) in cruciferous crops are extremely similar in appearance but they however showed differences in their levels of susceptibilities to various insecticides. The lacking of genomic and transcriptomic information on B. brassicae and L. erysimi limits our understanding of resistance status among aphid species at the molecular level. Based on the mining of the public transcriptome data, we identified a number of genes encoding three detoxifying enzymes, carboxylesterases (containing acetylcholinesterases), cytochrome P450s, and glutathione S-transferases. Several insecticide targets were also identified, such as acetylcholinesterase, nicotinic acetylcholine receptor, gamma-aminobutyric acid gated ion channel, glutamate receptor, the voltage-gated sodium channel, ryanodine receptor, transient receptor potential vanilloid channel, and inward-rectifier potassium channel. Our study provides genetic information for understanding the diversity of insecticide resistance occurring among cruciferous aphids, which could meaningfully contribute towards complementing future related studies.
