Pest identification
What's eating my mangrove date palm?
Red palm weevil (Rhynchophorus ferrugineus)
Signs: Spear leaf collapses and rots; larvae excavate the crown; distinctive fermenting odor from tunneling
Control: Trunk injection with imidacloprid or emamectin benzoate; pheromone trapping for early detection; apply wound paste after pruning
Rhinoceros beetle (Oryctes rhinoceros)
Signs: Triangular feeding cuts on emerging fronds; crown entry holes where adults excavate to feed
Control: Manual removal of beetles; Oryctes virus biocontrol; eliminate nearby breeding sites (rotting logs, compost heaps)
Scale insects
Signs: White or grey waxy deposits on fronds and stems; sap loss weakens growth; honeydew promotes sooty mold
Control: Horticultural oil spray; targeted removal; improve airflow around the palm's canopy where possible
