The adipokinetic hormones (AKHs) from of Hemiptera representatives have been isolated and identified using the LC/MS. The peptide data was used to create a dataset for comparative analyses. This resulted in total, in AKH sequences from 30 species (13 families) which are used here in a matrix confronted with the current hypotheses on the phylogeny of Heteroptera. The heteropteran database also suggests that particular AKH variants are family-specific. An unexpected diversity of AKH sequences is found in Nepomorpha, while Panbo-RPCH (which has been identified in all infraorders of decapod crustaceans) is present in all analysed species of Pentatomidae and also in the only species of Tessaratomidae investigated. The molecular evolution of Heteroptera with respect to other insect groups and to crustaceans is discussed.
