[6] Plants located under pecan or hickory trees are particularly susceptible to sooty mold, because honeydew-secreting insects often inhabit ...
Deposits of sooty mold caused by the fungus Scorias spongiosa build up below the colonies, growing on the copious amounts of honeydew the insects exude. [3] Multiple ant species are attracted, gleaning honeydew beneath aphid feeding areas at beech trees and tending aphids at the cypress tree sites.
Sooty moulds grow in thin black layers on leaves on which aphids, witefly or other sap-sucking insects have deposited their honeydew. It does not grow parasitically but it harms plants indirectly and is also unsightly. The mould coats the leaves and this blocks out light and makes photosynthesis less effective.

[1]
In addition to weakening the plant by sucking sap, they act as vectors for plant viruses and disfigure ornamental plants with deposits of honeydew and the subsequent growth of sooty moulds. Because of their ability to rapidly increase in numbers by asexual reproduction and telescopic development, they are a highly successful group of organisms ...
