Aphids on Faba Beans

Vicia faba L.

Aphids are a dangerous pest of faba beans, causing plant growth suppression and acting as vectors for viral diseases. The primary damage is caused by Aphis fabae, Acyrthosiphum pisum, and Aphis craccivora.

In the reference 9 varieties crop Broad bean, where this is mentioned in the description.

A complex of aphid species parasitizes faba beans, the most significant of which are the bean aphid, the pea aphid, and the cowpea aphid. Pests form colonies on young tissues, sucking sap from the phloem, which leads to leaf deformation, shoot curling, and general suppression of crop development, potentially resulting in seedling death.

Indirect damage is caused by the aphid's ability to transmit mosaic viruses and create favorable conditions for the development of sooty molds on the leaf surface, which feed on honeydew. Since no specific dominant resistance genes have been identified in faba beans, breeding is conducted based on quantitative traits and biochemical characteristics of the plants that influence the crop's attractiveness to the pest.
