Within a potato growing area, to reduce dissemination of viruses through viruliferous aphids, seed potato fields should be located upwind from commercial potato fields and alternative host crops. Aulavorthum have been made to use flightless coccinellids to improve the biological control of insect pests such as aphids, as the adult beetles are unable to fly away from the host plants.
Aphid populations are generally low in areas with low temperature, abundant rainfall and high wind velocity. Feeding also causes irregular curling of young potato leaflets and it is speculated that growth of the leaflet is hindered as a result of the feeding puncture.
The siphunculi are straight and pale, 1. Kibata describes an integrated control approach which has been successful in Kenya. Seed potatoes are very susceptible to infection at this stage, and so potato stores should be fumigated when sopani has finished, ensuring even distribution of smoke.

The high toxicity of the saliva of the glasshouse – potato aphid may produce deformation and discoloration of leaves being fed upon.
However, more stringent permitted levels of virus infection in seed potato certification programmes has increased the importance of aphids as virus vectors, since a very small percentage of infection can lead to rejection of an entire seed lot. It is known to be a major insect pest on tomatopepperstobaccocelerycarrotstulip bulbscucurbits and legumes.
Infection sources Primary hosts of the virus should be eliminated. In non-persistent transmission of viruses, aphids transmit viruses faster than common aphicides can react to kill the vector.
