An attempt was made to find a race of Pisum sativum (L.) more resistant than the race 'Onward' to Acyrthosiphon pisum (Harris) by evaluating 1250 races. On the basis of aphid weight, progeny, and longevity, 20 pea races were Significantly more resistant than Onward. Aphids reared on one race (PI 244160) of peas were 21% lighter in weight than those reared on Onward. Reductions of 28% in number of progeny and 24% in longevity were found in other races. Two pea races ('Konservenkonigen' and 'Scescio Tygodniowy.') were significantly more susceptible than the susceptible race 'Perfection', and aphids on them were ca. 29% heavier.
