Aphids on Passion Fruit Vines

Commonly affects: Passiflora edulis (Passion Fruit)

Clusters of small soft-bodied insects gather on new growth and flower buds, leaving sticky honeydew and sometimes transmitting woodiness virus.

Potential Causes

  1. 1Warm weather and tender new vine growth attracting colonisation
  2. 2Ants farming and protecting aphid colonies
  3. 3Aphids also spreading passion fruit woodiness virus between plants

Solution Steps

  1. 1Spray colonies off with a strong jet of water
  2. 2Apply insecticidal soap or neem oil to new growth, repeating every 5-7 days
  3. 3Encourage ladybugs and lacewings as natural predators
  4. 4Control ants nearby, since they protect aphids from predators

Prevention Tip

Aphid control matters doubly on passion fruit since they're also the main vector for woodiness virus — treat promptly.
