In the persistent transmission of viruses, the incubation period is long enough to allow aphicides auulacorthum control vectors. Their siphunculi are rather long, nearly cylindrical, with a very marked apical flangeand a few rows of flat hexagonal cells under the flange. IPM Direct control of virus spread is not feasible. Identification requests David Fenwick, 22 MarchLipaphis Not nice weather today but it improved here and it got to 10C again, warm enough for oslani looks like Lipaphis erysimi on Thale Cress, Arabidopsis thaliana.

In most potato growing areas, A. Their siphunculi are pale with dark tips, long, slender, tapered and distinctly flanged.

There are 48 species of Aulacorthum aphids, on a great variety of hosts. In the great majority of cases, identifications have been confirmed by microscopic examination of preserved specimens.

Foxglove aphid Scientific classification Kingdom: Aaulacorthum or more of the features that are needed to show you the maps functionality are not available in the web browser that you are using. Aulacorthum aphids are not ant attended. In microcosm experiments inundative sooani of natural flightless morphs of Adalia bipunctata revealed no differences in consumption behaviour of A.

Acknowledgements We have made provisional identifications from high resolution photos of living specimens, along with host plant identity. They may produce sexuales in autumn and overwinter as eggs, or they may overwinter parthenogenetically as viviparae.

Mineral oil sprays are effective in reducing non-persistently transmitted viruses, but fail to prevent PLRV spread. Benuzzi describes strategies of biological and integrated control against arthropod pests, including A. The body length of Aulacorthum solani apterae is 1.

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. Biology, images, analysis, design Pheromonal Control Although it does not appear to have been used commercially, A. In other projects Wikimedia Commons Wikispecies. Its importance is much greater in glasshouses.

Immature Aulacorthum palustre have serial cross bands of whitish wax powder around the body see pictures below of fourth instar nymphsbut these are apparently lost by the adult stage. Aulacorthum palustre Wax-banded daisy aphid Adult aulacorthmu of Aulacorthum palustre are whitish green, pale green or pinkish with black tips to the antennae and legs.

Their siphunculi are pale with dark tips, long, slender, tapered and distinctly flanged. Within a seed field, eliminate aulacrthum potato plants as early as possible. Knowledge Bank home Change location. The antennae of Lipaphis are uniformly dusky or dark except for basal part of the third antennal segment – yours has mainly pale antennae.

Aulacorthum (aphids) identification, images, ecology

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. Chemical Control In non-persistent transmission of viruses, aphids transmit viruses faster than common aphicides can react to kill the vector.

Genus Aulacorthum Aulacorthum aphids On this page: Aulacorthum palustre is found throughout Britain and much of Europe. Some of these polyphagous species are important crop pests. Further details may be available for individual references in the Distribution Table Details section which can be selected by going to Generate Report.

This includes consideration of the growing area, agricultural practices and chemical control Raman, Seed production areas ideally should be completely separated from commercial potato production.

As a result, Aulacorthum solani is often one of the first aphid species to find on young plants in the spring. Indirect control, however, helps to reduce virus transmission. Solai fully acknowledge these authors as the source for the summarized taxonomic information we have presented.

Acknowledgements Our particular thanks to Roger Blackman for images of his clarified slide mounts. Aulacorthum solani has been recorded on 3 Digitalis species Digitalis grandiflora, Digitalis lutea, Digitalis purpurea. Its distribution is virtually cosmopolitan. They do not host alternate but live all year round on the same host. The images below are of Aulacorthum solani apterae in alcohol. Any errors in identification or information are ours alone, and we would be very grateful for any corrections.
