摘要： The alfalfa plant bug Adelphocoris lineolatus (Goeze) (Hemiptera: Miridae), a serious pest of several agricultural crops, is extremely attracted by flowering plants to perform season host switching. Generally, chemoreception of A. lineolatus plays a crucial role in detecting food sources, locating mates and oviposition sites. In addition, odorant carrier proteins are believed to participate in the initial chemical communication and perception in insects. In this work, we identified 31 putative odorant carrier protein genes from the antenna) transcriptomes of A. lineolatus, including 17 new odorant binding proteins (OBPs), 10 new chemosensory proteins (CSPs) and four Niemann-Pick type C2 proteins (NPC2s). Phylogenetic analysis demonstrated that the OBP and CSP genes from four mind bug species (A. lineolatus, Adelphocoris summits, Apolygus lucorum and Lygus lineolaris) had a relatively close evolutionary relationship. Regular patterns and key conserved motifs of OBPs and CSPs in Hemiptera insects are also identified by using Multiple EM for Motif Elicitation (MEME) tool. Tissue expression profiles analysis showed that nine of the 17 OBPs, 10 CSPs and two of the four NPC2s were primarily or uniquely expressed in the adult antennae suggesting their putative roles in chemoreception. Our study provides the first insight into the roles of odorant carrier proteins in chemoreception of A. lineolatus, which will help to facilitate biological functions of odorant carrier proteins and develop novel insect behavioral regulation strategy in future.
