A new species of thrips (Klambothrips myopori) has recently been discovered attacking naio (Myoporum sandwicense) on Hawaii Island. These insects have been injuring and killing other species of Myoporum in
California and have now arrived in Hawaii. The insects cause gall-like
damage in young leaves and may eventually kill the
tree. They initially were found on cultivated naio papa at resort areas
in the South Kohala and North Kona districts and Waikoloa Village and
have spread to natural naio populations in Kau and Hawaii Volcanoes
National Park and has been found on landscape plantings in Hilo. These
thrips only attack naio (
Myoporum spp.) To prevent this pest
from spreading to neighbor islands, please do not move naio off Hawaii
Island. If you find these insects attacking naio on other islands,
especially wild populations, please notify Cynthia King, Hawaii Division
of Forestry and Wildlife Entomologist, (808) 587-0019, or by email at
firstname.lastname@example.org, or call the Hawaii Pest Hotline 643-PEST.
