SUMMARY Resistance to Sitobion avenue and Metopolophium dirhodum was assessed in the glasshouse by releasing immature aphids on uncovered wheat and barley plants at the tillering stage. Six cultivars of winter wheat were tested with S. avenue and of these cv. Kador was resistant and cv. Maris Huntsman susceptible. Among seven cultivars of barley, cv. CI16145 was more resistant to S. avenue than any other whilst cvs Tyra and Nirakei 10 were the most susceptible, but the cultivars did not differ significantly in the numbers of M. dirhodum on them, although there were ranking differences similar to those observed with S. avenue .
