Aphid Infestation

Aphids are small, soft-bodied insects that pierce the citrus leaves to suck out sap, excreting a sugary substance known as honeydew. This residue makes the Satsuma mandarin leaves feel sticky and can lead to the growth of black sooty mold.

Very Common

How to confirm: Inspect the undersides of new leaves and tender shoots for tiny, green or black moving insects.

Scale Insects

Scale insects attach themselves to citrus branches and leaves, feeding on the plant's vascular fluids. Similar to aphids, they excrete honeydew which creates a persistent sticky film on the foliage.

Very Common

How to confirm: Look for small, raised bumps or shell-like structures firmly attached to the stems or leaf veins.

Whitefly Infestation

Whiteflies congregate on the underside of citrus leaves and feed on the sap, leaving behind sticky honeydew. A sudden cloud of tiny white insects may appear when the plant is disturbed.

Common

Mealybugs

Mealybugs are slow-moving insects covered in a white, waxy substance that feed on citrus sap and produce honeydew. They often hide in the crevices of the stem junctions where sticky residue accumulates.

Common
