What's eating my papaya?

Papaya is most severely damaged by the papaya mealybug, which transmits papaya mosaic and leaf distortion viruses. Spider mites cause leaf bronzing in dry conditions, and whiteflies spread papaya ringspot virus — the single most economically damaging disease of papaya worldwide. Reflective mulches and insecticidal soap help manage both.

White cottony masses on stems, leaf undersides, and fruit; yellowing, leaf curl, and stunting; transmits papaya mosaic and leaf distortion viruses. Release parasitic wasps (Acerophagus papayae, Anagyrus loecki) where available; apply neem oil or insecticidal soap. Quarantine new plants; do not move infested material.

Yellowing leaves with sticky honeydew and black sooty mould; primary vector of Papaya Ringspot Virus (PRSV), causing mosaic, distorted leaves, and ring-spotted fruit. Use reflective silver mulch to deter adults; apply yellow sticky traps; neem oil or insecticidal soap for direct control. Remove and destroy virus-infected plants to reduce inoculum.

Fine bronze stippling on leaf upper surfaces; webbing on undersides; severe infestations cause premature leaf drop. Increase watering and humidity; spray undersides of leaves with neem oil, horticultural oil, or introduce predatory mites.

Female stings immature green fruit to oviposit; larvae rot the fruit from inside; premature fruit drop with dark sting marks visible on skin. Harvest fruit promptly when mature; use protein bait sprays (spinosad + hydrolysed protein); bag developing fruit with paper or fine-mesh bags.
