Aphids are sap-sucking insects that attack many different types of plants and are major transmitters of crop-infecting viruses. By altering plant biochemistry,...

Potato virus Y (PVY) is a plant pathogenic virus of the family Potyviridae. It is one of the most important plant viruses affecting potatoes. Infection results in various symptoms depending on the strain. Production loss is the most mild of the symptoms and "˜potato tuber necrotic ringspot disease' is the worst. Ringspot renders potatoes unmarketable and can therefore result in a major loss of income. Aphid vectors transmit PVY but it can also remain dormant in seed potatoes. The South...
