Ten aphid species were used as prey for Adalia bipunctata and six of them (Euceraphis betulae, Cavariella konoi, Liosomaphis berberidis, Acyrthosiphon ignotum, Aphis farinosa and Macrosiphoniella artemisiae) are new essential preys for this coccinellid. Eucallipterus tiliae and E. betulae were the most suitable prey according to the rate of larval development, larval mortality, adult fresh weight and coccinellid abundance in the field. A. farinosa from Salix caprea and Aphis fabae from Philadelphus cnronarius were not very suitable as food due to the larval mortality (27 % and 23 %, respectively). A. fabae from Atriplex sagittata and Aphis spiraephaga were an unsuitable prey.
