Description: The black twig borer (Xylosandrus compactus Eichhoff), first discovered in Hawaii in 1961, has become widespread on many host plants throughout the islands. Beetle infestations have caused heavy damage to trees but only recently have attacks been associated with death of apparently vigourous trees in forest stands. The beetle and its associated micro-organisms have been identified as associated with the death of five tree species in planted forests on Oahu.

Keywords: Xylosandrus compactus, Tristania conferta, Syncarpia glomulifera, Melaleuca leucadendron, Eucalyptus sideroxylon, plantations stands, Eucalyptus pilularis, insect damage, Hawaii, crown mortality, tree mortality
