Damage caused

  • Their feeding distorts new growth and can transmit plant viruses. They produce honeydew, which encourages the growth of sooty mould.

Monitoring steps

  • Randomly check young shoots in early and mid Spring for spring flush, and again in late summer through to mid Autumn for the Autumn flush. Check randomly selected young shoots, and examine five to ten young leaves from each shoot for the presence of aphids, honeydew and sooty mould. (NSW DPI)

Controls

  • Control action is needed only when 25% or more of leaf flushes are infested and when the presence of beneficial insects on infested shoots is less than 25%. Appropriate actions include spraying young growth with a specific aphicide.
