Pest identification
What's eating my australian fan palm?
Scale insects
Signs: Small brown or gray encrustations on fronds and petioles; sap removal causes yellowing fronds and sooty mold from honeydew
Control: Spray horticultural oil or insecticidal soap in spring when crawlers are active; repeat after 2–3 weeks
Rhinoceros beetle (Oryctes species)
Signs: Adults bore into the growing crown, leaving characteristic V-shaped cuts on emerging fronds and can kill the apical meristem
Control: Remove and destroy breeding sites (rotting wood, compost heaps) nearby; apply entomopathogenic fungi (Metarhizium) to breeding material; physical removal of beetles at night
Palm leaf skeletonizer caterpillar
Signs: Larvae feed in groups on both frond surfaces, consuming tissue between veins and leaving dark tube-like skeletonized remains
Control: Spray Bacillus thuringiensis (Bt) on affected fronds; pyrethrin-based insecticide for heavy infestations
