Abstract

Guandaushi forest ecosystem is a long-term ecological research (LTER) site in central Taiwan. There are totally 326 vascular plant species in which 27 species belonging to 16 families bear insect-induced galls. Among these host plants, 8 species are vines and 19 species are woody trees. Six species of Lauraceae and four species of Fagaceae have galls. Forty-five morphologically different insect-induced galls were found. About 60% are prosoplasmatic galls based on Küster classification; 50% are covering galls based on Dreger-Jauffret and Shorthouse classification. The gall makers of Cecidomyiidae (Diptera) induced 9 different galls.
