Leaves from 74 spring oat plants collected during 1960 in six New York counties were tested for infection by barley yellow dwarf virus (BYDV) by means of Rhopalosiphum padi, Macrosiphum granarium, Rhopalosiphum maidis, and Toxoptera graminum. The virus was recovered from 64 samples by M. granarium only, from 6 by M. granarium as well as by 1 or more of the other aphid species, from 1 by both R. padi and T. graminum, and from 1 by R. maidis only. During 1957, 1958, 1959, and 1960, BYDV was transmitted specifically by M. granarium from 81, 85, 84, and 86%, respectively, of the 197 spring oats collected in New York and tested during the 4 years by means of both M. granarium and R. padi. Several lines of evidence suggest that M. granarium was the most important natural vector of barley yellow dwarf virus in New York during the past four seasons.
