ABOVE: Close-up of adult and juvenile melon aphids.
ABOVE: Aphid colony feeding on young noni leaves. Young leaves are curled and distorted due to heavy feeding by the aphids.
Aphids are sap-feeding insects. Their feeding damage to noni is usually not significant, but can result leaf distortion or the formation of black sooty mold on noni leaves.
