Black Bean Aphid (Aphis fabae)
Dark aphid species attacking beans, ornamentals and many field crops.
Black bean aphid (Aphis fabae) forms dense black colonies on stems, shoot tips and flower buds of beans, dahlias and many ornamentals. It causes distortion, reduced flowering and heavy honeydew production that supports sooty mould. Biological control relies on parasitoids such as Aphidius ervi and predators including Aphidoletes aphidimyza and ladybirds. Removal of strong weed hosts such as Fat Hen and early biological introductions are key IPM tools.
