The relative proportions of free amino acids as well as the amino acid compositions of hydrolysed unpiecipitated peptides and hydrolysed whole carcasses were quantified for two aphid species the gall-dwelling social aphid Pemphigus spyrothecae and the pea aphid Acyrthosiphon piston The whole-tissue amino acid profiles of the two taxonomically distant species had a surprisingly high level of correspondence In contrast, when comparing the A piston profiles obtained in the current study to those obtained in an earlier study, major differences were identified It is concluded that there are good prospects for developing an artificial diet for P spyrothecae There may also exist considerable scope for tailoring the existing diets of A mum to suit specialised populations which develop poorly on the standard diet The amino acid profile of P spyrothecae is the first such profile that has been reported for a gall-forming aphid
