Forest Pests: Insects And Disease

Chair: Robert Hauff, DLNR Division of Forestry and Wildlife, Honolulu, HI

Wednesday, August 3, 10 AM - 12 PM, Room 313A

Forest pests damage Hawai‘i’s forest ecosystems, both native and non-native, reducing their biological, cultural, and economic values. In the past decade several significant pests have been accidently introduced to Hawai‘i raising public concern. Perhaps the most concerning is the introduction of guava rust or ‘ohia rust’ (Puccinia psidii) which has an unusually wide host range in the Myrtaceae family. Researchers have been documenting the existence of multiple strains worldwide to support establishment of quarantine rules to safeguard Hawai‘i’s most important forest tree. Insect pests such as the Erythrina gall wasp (Quadrastichus erythrinae) and Myoporum thrips (Klambothrips myopori), also recently introduced, have damaged forest resources in throughout the state. Since options for control of many forests pests are limited once they are established in the state, prevention is of paramount importance.
