Symptoms and damage

Eriophyid mites are sap-sucking insects. When the mites feed, they cause plant abnormalities including:

  • galls
  • blisters
  • distortion of new growth
  • discolouration of foliage
  • witches broom (deformed growth that resembles a broom)
  • felty patches on leaves.

Damage can be found on leaves, stems, or flower buds depending on the species of mite and host species. The damage is mainly aesthetic.

Prevention and control tips

  • Biological control organisms.
  • Chemical insecticides.
  • Miticides.
