Potato virus Y (PVY) is one of the most economically important viruses affecting the potato crop. Several strains of the virus, including PVYO, PVYN, recombinant isolates; PVYN:O (PVY (N-Wi)) and PVYNTN and several variants of PVYO have been reported from North American potato-production areas. The green peach aphid, Myzus persicae Sulzer, is a colonizer of potatoes and is considered the most important vector of PVY. The objective of this study was to measure the population growth of M. persicae on potato plants infected with different strains and genetic variants of PVY. The initial population of ten winged adults of M. persicae was allowed to develop on a potted plant for 12 days. Results clearly indicated that infections by different strains and genetic variants of PVY did not influence the population growth of M. persicae on potato plants during this period.
