Aphids are a small green or brown sucking insect that sit on the new growth and stems of Jasmine. They will suck the water and sap from the Jasmine plant. This will damage the plant over time as it loses moisture and nutrients.
Aphids will release a sticky sweet substance when they feed on the stems. This can attract ants which can transfer other diseases from the soil to the plant. A Jasmine plant infested with aphids can also be quickly covered in ants.
The problem of ants can be as bad as getting all over you, your kids and pets. Dealing with the aphid problem will also deal with the ant problem by taking away their food source.
Without the aphids producing the honeydew, there is nothing that attracts ants to Jasmine, except perhaps the leftover sticky substance.
Sooty mold will form in the areas infected by the aphids as it grows on the areas of the secreted honeydew. Black sooty mold looks dark and horrible and white mold can also form in these areas.
White mold will look fluffy, like it is a creature itself but will form around the area of honeydew. It can be seen where the leaf stem meets the branch.
