- Excrete honeydew on which sooty mould develops covering affected parts with a thin superficial black coating that hinders photosynthetic activity of leaves resulting in stunted growth of plants.
- In addition, they also act as vectors, for transmitting several viral diseases.

Description
- A relative humidity of 66+2.8% and 11-140°C temperature are ideal for development of this aphid.
