  • Main crops attacked are ornamentals, cotton and vegetables, especially transplants and seedlings of greenhouse vegetables
  • Nymphs or ‘crawlers’ range from pale green to brown and resemble scale insects
  • Adults (1.5 mm long) resemble tiny moths, with pale yellow wings that are held flat
  • Key impact of infestation is the production of honeydew, which encourages the development of sooty mould
  • Heavy infestations can result in leaf wilting and failure to set seed
  • Spread with infested plant material, on people and by wind
