AphID – Aulacorthum solani

The high toxicity of the saliva of the glasshouse – potato aphid may produce deformation and discoloration of leaves being fed upon.

Aaulacorthum often have rust-coloured or darker green spots around the bases of the siphunculi.

In the great majority of cases, identifications have been confirmed by microscopic examination of preserved specimens. Go to distribution map Its feeding causes discoloured spots on tobacco, and heavily infested plants can show large necrotic areas, sometimes resulting in the senescence of the entire leaf. Infection sources Primary hosts of aulacorthkm virus should be eliminated.

Unusually for an aphid, Aulacorthum solani can go through the sexual phase on many different plant species – but, in temperate climates, most of their population overwinters as nymphs or apteraeespecially on potato sprouts and on many glasshouse plants and wild species such as foxglove Digitalis. From Wikipedia, the free encyclopedia. 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.
