Banana Aphids

Commonly affects: Musa acuminata, M. balbisiana (Banana)

Small dark aphids cluster on the underside of young leaves and around the base of the pseudostem, feeding on sap and potentially transmitting bunchy top virus.

Potential Causes

  1. 1Banana aphids (Pentalonia nigronervosa) colonising new growth and leaf bases
  2. 2Warm, humid conditions favouring rapid reproduction
  3. 3Ants farming aphid colonies for honeydew

Solution Steps

  1. 1Spray colonies with insecticidal soap or neem oil, reaching into leaf bases where aphids hide
  2. 2Remove heavily infested suckers if bunchy top virus symptoms are also present
  3. 3Control ants nearby, since they protect and spread aphid colonies
  4. 4Inspect new suckers before transplanting them to other areas

Prevention Tip

Banana aphid control matters beyond the insects themselves, since they're the sole vector for the far more serious bunchy top virus.
