Adventive Thysanoptera Species in the Hawaiian Islands: New Records and Putative Host Associations

Fifteen adventive species of Thysanoptera, comprising eight Thripidae and seven Phlaeothripidae, are recorded for the first time from the Hawaiian Islands. Four of these are native Australian species, seven are native to south- eastern Asia, with one species known only from Costa Rica and one known from several sites around the Caribbean. New host and locality records are given for a further 15 species, and the situation is noted that some species established on the Hawaiian Islands are pests in other parts of the world but have failed to become problematic here
