Pests
Aphids on Pumpkin Vines
Commonly affects: Cucurbita pepo, C. maxima, C. moschata (Pumpkin)
Clusters of small, soft-bodied insects gather on new growth and the underside of young leaves, often leaving sticky honeydew residue and causing curling of affected foliage.
Potential Causes
- 1Warm weather and vigorous new vine growth attracting aphid colonisation
- 2Ants farming and protecting aphid colonies for their honeydew
- 3Nearby infested plants seeding new colonies onto pumpkin vines
Solution Steps
- 1Spray affected shoot tips with a strong jet of water to dislodge colonies.
- 2Apply insecticidal soap or neem oil, focusing on new growth and leaf undersides, repeating every 5-7 days.
- 3Encourage ladybugs and lacewings, which feed heavily on aphids, by avoiding broad-spectrum pesticides.
- 4Control ant activity nearby, since ants protect aphid colonies from natural predators.
Prevention Tip
Check new vine tips regularly during warm weather â aphids target the softest, fastest-growing parts of the vine first.
