Aphids display an extraordinary phenotypic plasticity ranging from widespread reproductive and wing polyphenisms to the occurrence of sterile or subfertile soldier morphs restricted to eusocial species of the subfamilies Eriosomatinae and Hormaphidinae. Individual morphs are specialized by their behavior, anatomy, and physiology to perform different roles in aphid societies at different stages of the life cycle. The capacity of the insects to cope with environmental stressors is under the control of a group of neuropeptides of the adipokinetic hormone/red pigment-concentrating hormone family (AKH/RPCH) that bind to a specific receptor (AKHR). Here, we describe the molecular characteristics of AKH and AKHR in the eusocial aphid Pseudoregma bambucicola. The sequence of the bioactive AKH decapeptide and the intron position in P. bambucicola AKH preprohormone were found to be identical to those in a phylogenetically distant aphid Dreyfusia spp. (Adelgidae). We detected four transcript variants of AKHR that are translated into three protein isoforms. Further, we analyzed AKH/AKHR expression in different tissues and insects of different castes. In wingless females, a remarkable amount of AKH mRNA was only expressed in the heads. In contrast, AKHR transcript levels increased in the order gut
