    sequencing data, we identified cDNAs encoding AKH (GbAKH) and its highly homologous hormone AKH/corazonin-related peptide (GbACP) in the corpora cardiaca of the two-spotted cricket, Gryllus bimaculatusgryllus bimaculatusSubject Category: Organism Names

    . RT-PCR revealed that GbAKH and GbACP are predominantly expressed in the corpora cardiaca and corpora allata, respectively. Phylogenetic analysis confirmed that the identified GbAKH and GbACP belong to the clades containing other AKHs and ACPs, respectively. Injection of synthetic GbAKH and GbACP elevated hemolymph carbohydrate and lipid levels and reduced food intake significantly. In contrast, knockdown of GbAKH and GbACP by RNA interference increased the food intake, although hemolymph lipid level was not altered. Collectively, this study provides evidence that ACP regulates hemolymph carbohydrate and lipid levels in cricket, possibly collaborative contribution with AKH to the maintenance of energy homeostasis.
