In a field study in Belgium, rates of parasitism of A. 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. Natural essential oils have also shown effectiveness against A.

Virus spread early wolani the season is more serious than later on, as young plants are generally more susceptible.

AphID – Aulacorthum solani

Continuing to use www. Taxonomic Tree Top of page Aluacorthum Don’t need the entire report? Aulacorthum solani can also be a vector of about 40 plant viruses, but its relatively poor virus transmission efficiency makes it unimportant as a virus vector in the field. 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. 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.

Their siphunculi are rather long, splani cylindrical, with a very marked apical flangeand a few rows of flat hexagonal cells under the flange. We fully acknowledge these authors as the source for the summarized taxonomic information we have presented.

Vols 1 and 2. Knowledge Bank home Change location.

Aphid populations are generally low in areas with low temperature, abundant rainfall and high wind velocity. The alate Aulacorthum palustre is reddish or greenish with a brown or black abdominal dorsal pattern. Indirect damage is caused by honeydew production and virus transmission. Aulacorthum solani can also be a vector of about 40 plant viruses, but its relatively poor virus transmission efficiency makes it unimportant as a virus vector in the field.

The body length of Aulacorthum solani apterae is 1. Benuzzi describes strategies of biological and integrated control against arthropod pests, including A. The dorsum is sclerotic and shiny.

The high toxicity of the saliva of the glasshouse – potato aphid may produce deformation and discoloration of leaves being fed upon. Acknowledgements We have made provisional identifications from high resolution photos of living specimens, along with host plant identity.

The antennal tubercles are well developed with near parallel steep-sided inner face cf. Examples aulaclrthum biological control agents used against A. The cauda is rather short and tongue-shaped.

The systemic insecticide imidacloprid was used to control aphid vectors of Soybean dwarf virus in Japan Honda et al.

Honeydew, a sticky liquid excreted by the aphid, covers the foliage and is often colonized by black saprophytic fungi, hampering respiration and photosynthesis. Rasocha describes carbamates and pyrethroids used for aphid control. In the persistent transmission of viruses, the incubation period is long enough to allow aphicides to control vectors.

Within a seed field, eliminate infected potato plants as early as possible. In the great majority of cases, identifications have been confirmed by microscopic examination of preserved specimens. The body length of Aulacorthum solani apterae is 1. Except where otherwise specified, all text and images on this page are copyright InfluentialPoints under a Creative Commons Attribution 3.

The dorsum and antennae have short capitate hairs. Cultural Control Selection of growing area Because virus spread is related to aphid populations, seed aulacortuum areas should be selected on the basis of aphid population studies.

They may produce qulacorthum in autumn and overwinter as eggs, or they may overwinter parthenogenetically as viviparae. Yellow, flowering weeds and any other host plants within and around the field should also be removed. In most potato growing areas, A.

Extracts of the weed Artemisia vulgaris have shown toxicity to potato aphids Metspalu and Hiiesar, 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. Furthermore, plants that are infected early become more efficient sources for further virus spread than plants infected later in the season.
