Aphids on Banana Plants
Aphids are small, soft-bodied insects that cluster on new growth, feeding on plant sap. On banana plants, they are found on young, unfurling leaves and around the flower bud. Besides direct feeding damage, aphids are the primary vector for Banana Bunchy Top Virus, making their control especially important in areas where that disease is present.
Identification
Small (1-3mm) green, yellow, brown, or black soft-bodied insects, usually in clusters. They leave behind a sticky residue called honeydew, which often develops black sooty mold.
Treatment
- Strong water spray to physically remove them
- Insecticidal soap or neem oil — repeat every 5-7 days
- Encourage natural predators — ladybugs, lacewings, parasitic wasps
- For heavy infestations, systemic insecticides are effective but use as a last resort
