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
