The temporal and spatial distribution of zucchini yellow mosaic potyvirus (ZYMV) was studied in a 3000‐m 2 zucchini squash field. The first infected plants were found 4 weeks after the field was exposed to virus source plants. The infection increased to nearly 74% by the end of the study. Alate aphids were active from the beginning of the study and 43 species were trapped in the field. Flights of vector species Acyrthosiphon pisum and Myzus persicae peaked during the fourth week which resulted in high virus incidence 4 weeks later. There was a significant correlation between the number of vectors caught in yellow pan traps and the number of infected plants in the field. In laboratory studies evaluating 11 aphid species, Aphis pomi de Geer was identified as a new vector species of ZYMV. Although this aphid was not caught in our field studies, it may be an important contributor in other areas where cucurbits are grown in close proximity to apple or other hosts of this aphid.
