Aphids on Orchid Flower Spikes
Commonly affects: Phalaenopsis spp. and other Orchidaceae (Orchid)
Small soft-bodied insects cluster on tender new flower spikes and buds, sometimes causing distorted bud development and sticky honeydew residue.
Potential Causes
- 1Aphids attracted to the soft, tender tissue of developing flower spikes
- 2Introduction from a nearby infested plant
- 3Ants farming aphid colonies for honeydew
Solution Steps
- 1Rinse spikes gently with lukewarm water to dislodge light infestations
- 2Apply diluted insecticidal soap carefully to avoid damaging delicate flower buds
- 3Isolate the affected plant from other orchids
- 4Inspect new flower spikes regularly, since this is where aphids target first
Prevention Tip
Check new flower spikes weekly as they develop â aphids target this soft, tender growth before spreading elsewhere on the plant.
