AphID – Aulacorthum solani

Aphid populations are generally low in areas with low temperature, abundant rainfall and high wind velocity. Taxonomic Tree Top of page Domain: Mineral oil sprays are solanni in reducing non-persistently transmitted viruses, but fail to prevent PLRV spread.

Please help to improve this article by introducing more precise citations. We fully acknowledge these authors as the source for the summarized taxonomic information we have presented.

Except where otherwise specified, all text and images on this page are copyright InfluentialPoints under a Creative Aulacortjum Attribution 3. As a result, Aulacorthum solani is often one of the first aphid species to find on young plants in the spring.

Aphicides can greatly reduce Potato leafroll virus PLRV spread within a field, but they cannot control infections from outside by migrating aphids. It utilizes virus-resistant cultivars, certified seed, the removal of diseased plants and the use of systemic insecticides at planting, followed by foliar-sprayed systemic insecticides.

The winged forms have darker antennae, legs and siphunculi aulacortthum have a variably developed pattern of tranverse dark bars on the dorsal abdomen. Continuing to use www. The foxglove aphidAulacorthum solanialso known as glasshouse-potato aphidis an aphid in the superfamily Aphidoidea in the order Hemiptera. 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.


Yellow, flowering weeds and any other host plants within and around the field should also be removed. Infection sources Primary hosts of the virus should be eliminated. They may produce sexuales in autumn and overwinter as eggs, or they may overwinter parthenogenetically as viviparae. Dried tobacco leaf smoke showed some effectiveness against aphid pests, including A. Retrieved from ” https: Benuzzi describes strategies of biological and integrated control against arthropod pests, including A.

Tuber storage Aphids readily colonize tuber sprouts and so potato tubers must be protected during storage by preventing access of aphids and by using aphicides.

Aulacorthum solani is extremely polyphagousit will colonise plants in may different dicotyledonous and monocotyledonous families.

Aulacorthum palustre feed on the underside of leaves of plants in the daisy family Asteraceae such as cats ear Hypochaerisoxtongues Picrisand possibly dandelions Taraxacum and hawkbits Leontodon. 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 brown or with brown apices. Their siphunculi are rather long, nearly cylindrical, with a very marked apical flangeand a few rows of flat hexagonal cells under the flange. Cookies on Plantwise Knowledge Bank Like most websites we use cookies.

Aulacorthum solani solani

Although it does not appear to have been used commercially, A. Light infestations of Solain. Indirect control, however, helps to reduce virus transmission. Pheromonal Control Although it aolani not appear to have been used commercially, A. Aulacorthum solani Glasshouse – potato aphid, Foxglove aphid Aulacorthum solani apterae are pear shaped and shiny greenish yellow, usually with a bright green or rust coloured patch at the base of each siphunculus.

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.

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


Aulacorthum solani Glasshouse – potato aphid, Foxglove aphid On this page: In the persistent transmission of viruses, the incubation period is long enough to allow aphicides to control vectors.

Species Aulacorthum solani – Foxglove Aphid –

Their siphunculi are pale with dark tips, long, slender, tapered and distinctly flanged. Gibson reported A. Within a field, aphicides may slightly reduce non-persistent virus transmission, but they cannot prevent it; neither can they control infections brought from outside the field by migrating aphids.

Moreover the cauda of Lipaphis erysimi is 0. With the use of organic insecticides, direct feeding damage has become less serious.

Other aphids on same host: Identification requests David Fenwick, 22 MarchLipaphis Not nice weather today but it improved here and it got to 10C again, warm enough for what looks like Lipaphis erysimi on Thale Cress, Arabidopsis thaliana. Silani, ; Gillespie et al. Further details may be available for individual references in the Distribution Table Details section which can be selected by going to Generate Report.

The antennal tubercles are well developed with near parallel steep-sided inner face cf. Aulacorthum solani can also be a vector of about 40 plant viruses, but its relatively poor virus transmission efficiency makes it unimportant as aulaxorthum virus vector in the field. We have made provisional identifications from high resolution photos of living specimens, along with host plant identity.

The alate Aulacorthum palustre oslani reddish or greenish with a brown or black abdominal dorsal pattern. Views Read Edit View history. The clarified slide mounts below are of adult viviparous female Aulacorthum solani: This results in direct feeding damage to potatoes and peppers. Aulacorthum solani Kaltenbach, They often have aulacorthuk or darker green spots around the bases of the siphunculi.
