Pacific Pests, Pathogens & Weeds - Mini Fact Sheet EditionCoconut spike moth (111)
Summary
- Narrow distribution. Southeast Asia. On coconut and oil palm, mostly. There are conflicting views on whether this moth is a pest. Nut fall occurs naturally, with the number adjusted to reserves of the palm; if the moth accounts for 10% then natural nutfall will be less, so that the overall effect on yield is negligible.
- Eggs are laid at the base of flowers and leaves; the larvae bore into female flowers causing them to fall.
- Natural enemies: wasp parastoids are known.
- Cultural control: in the Philippines MAWA hybrids are thought to be more susceptible.
- Chemical control: none recommended: unlikely to be economic, and insecticides will kill the parasitoids. Additionally, the pest status of this insect is uncertain
Common Name
Coconut spike moth, oil palm bunch moth
