The potato aphid (Macrosiphum euphorbiae) is of North American origin, but is these days distributed throughout the is a highly polyphagous species with a preference for Solanaceae (particularly potato), but has also been identified on more than plant species from more than 20 families.

Various vegetable and ornamental crops grown in greenhouses are colonized, including. If the traps have more than an average of four wireworms, the level is considered extreme and potatoes should not be planted in that field.

When using chemical treatments for wireworm suppression, pesticide applications should be delayed in the spring as long as possible in order for soil temperatures to increase to a point where wireworms are.

Five aphid species, M. persicae, M. euphorbiae, A. fabae, A. gossypii and A. spiraecola, were identified on potato leaves and in yellow water traps. They are recognized worldwide as potato.

In AphID, entities are the aphid species and morph, for example “Aphis gossypii alata”. The icon to the left of each entity in the Entities Remaining window will open the respective species page. Frequent use of the species pages will help your identification process as you can quickly confirm or.

To make it very simple: g of each product (salt and mustard powder) are added to 10 liters of. Other Aphid Resources: SASA operates four suction traps collecting insects flying at a height of m above the ground to provide a standardized measure of regional aphid activity.

The data are updated weekly for key species and assessments of regional risks of PVY transmission are provided using relative transmission efficiencies that are similar to those used by AHDB potatoes/Fera.potatoes include the peach–potato aphid, potato aphid and glasshouse–potato aphid.

Consequently, the numbers of key aphids caught in the aphid water traps and suction traps should be used as a guide to the risk of aphid movement into potato crops, and the beginning of the aphicide treatmentFile Size: KB.

Losses in potatoes associated with aphids in Washington are estimated at % annually, but can be much higher on individual farms. A key goal of this project is to reduce insecticide usage in potatoes without compromising performance.

The project will also develop comprehensive keys to beneficially important aphid-attacking parasitoids.
