In this study, 37 morphologically different types of insect galls was obtained in 22 tree and shrub species from one secondary successional area at the Campus-Pampulha of Universidade Federal de Minas Gerais, Belo Horizonte, Minas Gerais - Brazil, from august 1980 to december 1982. The cecidomiids are the most important gall-makers. They are founded in the leaves in all the plant species surveyed. The galls external morphologies are highly variable, however the inside aspect are uniform. The gall numbers are variable a mong the plant species. However, the cavity and larvae per cavity numbers is commonly one. Several dipterocecidian parasitoid families are also included in this survey.
