  • Widespread distribution. Tropical Asia, Africa, Oceania. On citrus, but also tea and roses. An important pest.
  • Eggs laid in spirals on under surface; 'crawlers' at first, and then flattened dark legless larvae; pupae with fringe of cottony wax.
  • Damage is done by sucking sap, and blackening leaves as fungi grow on honeydew excreta.
  • Natural enemies: parasitoid wasps.
  • Cultural control: prune infested branches; apply nutrients to assist growth; use hot water to destroy ants (ants protect whitefly from biocontrol agents).
  • Chemical control: use soap, white or horticultural oils. Use synthetic pyrethroids to kill ants.
