They may produce sexuales in autumn and overwinter as eggs, or they may overwinter parthenogenetically as viviparae. Chemical Control In non-persistent transmission of viruses, aphids transmit viruses faster than common aphicides can react to kill the vector. The siphunculi are straight and pale, 1.
There are 48 species of Aulacorthum aphids, on sollani great variety of hosts. Aulacorthum solani is extremely polyphagousit will colonise plants in may different dicotyledonous and monocotyledonous families. Furthermore, plants that are infected early become more efficient sources for further virus spread than plants infected later in the season.
Its importance is much greater in glasshouses.

Aulacorthum aphids are not ant attended. Bermudez recommends setting up of field units for data collecting on aphid population in principal potato areas used for seed potato production. IPM Direct control of virus spread is not feasible. In the great majority of cases, identifications have been confirmed by microscopic examination of preserved specimens.
Unusually for an aphid, Aulacorthum solani can go through the sexual soalni 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. Indirect damage is caused by honeydew production and virus transmission. Seed potatoes are very susceptible to infection at this stage, and so potato stores should be fumigated when migration has finished, ensuring even distribution of smoke.
Belousov, ; Gillespie et al.
Aulacorthum palustre Wax-banded daisy aphid Adult apterae of Aulacorthum palustre are whitish green, pale green or pinkish with black tips to the antennae and legs. Examples of biological control agents used against A. Light infestations of A.
Mizukoshi and Kakizaki reported the trapping of early instars of A. Articles with incomplete citations from September All articles ssolani incomplete citations Articles with ‘species’ microformats Articles lacking in-text citations from February All articles lacking in-text citations.
Indirect control, however, helps to reduce virus transmission. Extracts of the weed Artemisia vulgaris have shown toxicity to potato aphids Metspalu and Hiiesar, When several references are cited, they may give conflicting information on the status. Although it does not appear to have been used commercially, A. Their siphunculi are ahlacorthum with dark tips, long, slender, tapered and distinctly flanged.
The alate Aulacorthum palustre is reddish or greenish with a brown or black abdominal dorsal pattern. Retrieved from ” https: Distribution Maps Top of page You can pan and zoom the map. Fenthion and etofenprox were used by Okubo b during early stages of soyabean growth. Vols 1 and 2. Their siphunculi are rather long, nearly cylindrical, with a very marked apical flangeand solanl few rows of flat hexagonal cells under the flange.
Kibata describes an integrated control approach which has been successful in Kenya. Harvesting time After a viruliferous aphid has fed on potato foliage, the virus aulacorthu time to infect the tubers.
Immature Aulacorthum palustre have serial cross bands of whitish wax powder around the solsni see pictures below of fourth instar nymphsbut these are apparently lost by the adult stage. Dried tobacco leaf smoke showed some effectiveness against aphid pests, including A.
Aulacorthum solani – Wikipedia
Yellow, flowering weeds and any other host plants within and around the field should also be removed. Knowledge Bank home Change location. Aphid populations are generally low in areas with low temperature, abundant rainfall and high wind velocity. Its distribution is virtually cosmopolitan.
Any errors in identification or information are ours alone, and aulacorthmu would be very grateful for any corrections. In other projects Wikimedia Commons Wikispecies.
It has one of the broadest host ranges of any aphid in the world, where they both hosts on dicots and monocots. The aphid also transmits other viruses, including Cucumber mosaic virus Contangelo et al. They often have rust-coloured or darker green spots around the bases of the siphunculi.
Adams is tolerant to infection by Soybean dwarf virus SbDV in the field and exhibits antibiosis to A. Seed production areas ideally should be completely separated from commercial potato production.
