What's eating my jamaican tall coconut?

Jamaican Tall Coconut palms are most seriously threatened by the coconut rhinoceros beetle and red palm mite outdoors. In landscape settings, palm weevils can devastate the growing tip, and mealybugs cluster at leaf bases. Act early — once a weevil bores into the crown, the palm rarely recovers.

Silvery-bronze streaking on the undersides of fronds; premature frond drop and reduced fruit set. Spray with horticultural oil or a miticide (abamectin) at first sign; repeat every 7–10 days. Predatory mites (Neoseiulus baraki) give biological control.

Characteristic V-shaped cuts in unopened fronds; entry holes packed with fibrous frass at the crown. Remove and destroy breeding sites (dead logs, compost heaps). Apply entomopathogenic virus (OrNV) bait or neem-based insecticide to crown. Pheromone traps reduce adult populations.

Wilting and collapse of the spear leaf; larvae tunnel into the crown, causing rotting and palm death. Prevent wounds from tools or pruning during beetle flight periods. Apply systemic insecticide (imidacloprid) preventatively in high-pressure areas. Infested crowns usually cannot be saved.

White cottony masses at leaf bases and on fruit stalks; sooty mold follows heavy infestations. Dislodge colonies with a strong water jet; treat with insecticidal soap or neem oil, covering all crevices. Introduce Cryptolaemus beetles for large-scale control.
