Potato Virus Y (PVY) is a serious threat to high grade seed potato production because even low levels of PVY will downgrade seed. Not all aphid species transmit virus to your crop and those that do transmit do so with varying levels of efficiency. The peach-potato aphid (Myzus persicae) is the most efficient virus vector. Some vector species will colonise potatoes however, many will simply move on as potatoes are not a suitable food source. By identifying the species of aphids arriving we can provide information on whether your crop is at risk from virus spread and colonisation. The information you receive through the aphid monitoring scheme can bring the following benefits:
The scheme is also good news for the environment. A switch to a more rational use of insecticides may;
Other Aphid Resources: SASA operates four suction traps collecting insects flying at a height of 12.2m above the ground to provide a standardized measure of regional aphid activity. The data are updated weekly for key species and assessments of regional risks of PVY transmission are provided using relative transmission efficiencies that are similar to those used by AHDB potatoes/Fera. Information on the Scottish Seed Potato Classification Scheme is also available here.
