Pacific Pests, Pathogens and Weeds

Summary

  • Narrow distribution. Probably native of Fiji. Hosts are hibiscus, and members of the myrtle family, including Eucalyptus, Melaleuca, and Eugenia.
  • Damage done by adults chewing the flowers. 
  • Eggs coated with faeces drop to the ground. Larvae take very long time to emerge; they live in a case of their own faeces, are nocturnal and feed on dead leaves and bark, but maybe part-time on living plants. Adults with brown head  and black forewings. Often seen 'male-gating' (male on female preventing access to others).
  • Cultural control: hand-pick, checking both night and day.
  • Chemical control: unlikely to be needed, but if they are try biorational first: neem, pyrethrum or chilli.
