DAMAGE
Direct feeding damage is of little importance, as the
aphids do not form dense colonies. However, honeydew
is often a problem on pot plants, and the presence of cast
nymphal skins on foliage and flowers is unsightly.

),
Begonia, Calceolaria
, calla lily (
Zantedeschia
aethiopica
), carnation (
Dianthus caryophyllus
) and pink
