Male black cutworm moths (Agrotis ipsilon, Lepidoptera, Noctuoidea, Noctuidae), which are attracted by a three-component pheromone blend ((Z)-7-dodecenyl acetate, Z7-12:Ac; (Z)-9-tetradecenyl acetate, Z9-14:Ac; (Z)-11-hexadecenyl acetate, Z11-16:Ac), express diverse antennal pheromone binding proteins (PBPs). Two PBP isoforms (Aips-1 and Aips-2) that show 46% identity were cloned from antennal cDNA of male A. ipsilon. The protein Aips-1 displays a high degree of identity (70-95%) with PBPs of other noctuiids, but shows only 42-65% identity with the PBPs of more phylogenetically distant species. The other protein, Aips-2, represents a distinct group of PBP that includes proteins from Sphingidae and Yponomeutidae. These differences observed suggest that each of the two PBPs may be tuned to a specific pheromone ligand.
雄性小地老虎蛾（小地老虎，鳞翅目，夜蛾总科，夜蛾科）会被由三种成分组成的性信息素混合物（（Z）-7-十二碳烯基乙酸酯，Z7-12:Ac；（Z）-9-十四碳烯基乙酸酯，Z9-14:Ac；（Z）-11-十六碳烯基乙酸酯，Z11-16:Ac）所吸引，其表达多种触角性信息素结合蛋白（PBPs）。从小地老虎雄性触角cDNA中克隆出了两种同一性为46%的PBP亚型（Aips-1和Aips-2）。蛋白Aips-1与其他夜蛾科昆虫的PBPs具有高度同一性（70 - 95%），但与进化关系较远物种的PBPs同一性仅为42 - 65%。另一种蛋白Aips-2代表了一类独特的PBP，其中包括天蛾科和巢蛾科的蛋白。观察到的这些差异表明，这两种PBPs中的每一种可能都针对特定的性信息素配体进行了调整。
