Question
I am looking for possible treatment for sheplera plant parsites There is a shiny sticky residue on the leaves and insects. I don't know how they call them in English.

Answer
Hello Silvyia,

The insects are most likely scale insects which appear as small, circular/oval (circa 3 to 5mm diameter).  The juvenile stage of these insects are mobile and appear as small white (cotton-like) insects.  Mealybugs also produce the sticky residue, called honeydew.

Either can be controlled with insecticidal soaps, but once the mature scale insects establish feeding sites on the plant, they are very hard to control.  If you have a small infestation, you may use a discarded toothbrush to apply the insecticidal soap, using the toothbrush to loosen the insects.

Good Luck!

John
