• Unknown distribution. In Oceania, Fiji. A serious pest of Pandanus.
• Damage: larvae web tips of young leaves together and feed on the surface layers, which become silvery and withered as the leaves mature.
• Larva with flattened yellow body, red-brown head; pupa bordered by crescent-shaped mass of chewed leaf; adults light-brown, with hindwings fringed with thick hairs.
• Natural enemies: unknown.
• Cultural control: cut of tips of the leaves, and destroy the larvae.
• Chemical control: biorational pesticides: (i) botanicals (chillies, neem, derris, pyrethrum); (ii) microbials e.g., spinosad, Bt (Bacillus thuringiensis subspecies kurstaki) against young caterpillars; (iii) synthetic pyrethroids - avoid, if possible, as they are likely to destroy natural enemies, if present. Spot-spray damaged shoots rather than 'blanket' spray.
