Abstract
In the last 5 years Dutch seed potato growers have faced increasing problems with
Potato virus Y (PVY) despite a decrease over the past 20 years in the number of
aphids caught during the potato-growing season. In the Netherlands the control
system for PVY is based on virus monitoring in the field, flight data of aphids
and postharvest control. Aphids are caught, counted and assigned a value
according to their relative efficiency factor (REF). The aphid flight data are used
to set dates for haulm destruction. Given the current problems with PVY, this
system, developed in the 1980s, may no longer be adequate to control the current
virus situation in the field. Although it was found that REFs of different aphids
are still valid for transmission of PVYN, higher transmission rates were found for
PVYNTN and PVYN-Wilga. This could explain the increasing PVY infection in the
field
