What's eating my coconut palm?

Coconut mite / eriophyid mite (Aceria guerreronis)

Signs: Brown triangular lesions under the husk of young coconuts; shriveled, unmarketable fruit.

Control: Apply acaricides (e.g., wettable sulfur) to the crown and developing nuts; release predatory mites (Neoseiulus spp.) as biocontrol.

Rhinoceros beetle (Oryctes rhinoceros)

Signs: V-shaped cuts in emerging fronds; crown boring by adults can destroy the growing point.

Control: Use Oryctes nudivirus (OrNV) biocontrol; set up pheromone traps; apply Metarhizium fungus to breeding sites (rotting logs, compost).

Coconut leaf beetle (Brontispa longissima)

Signs: Adults and larvae scrape and feed inside unfurled spear leaves, causing brown streaking and reduced vigor.

Control: Introduce parasitoid wasps (Asecodes hispinarum) for biological control; apply systemic insecticide to the crown for severe infestations.

Red palm weevil (Rhynchophorus ferrugineus)

Signs: Larval boring in crown and stem; fermenting sap, internal rot, and eventual palm death.

Control: Use pheromone bait traps proactively; inject systemic insecticide at early detection; fell and destroy heavily infested palms.
