Three different galls of Bruggmannia spp. (Diptera, Cecidomyiidae) on Guapira opposita (Vell.) Reitz. (Nyctaginaceae) were studied at Restinga of Barra de Maricá, State of Rio de Janeiro. Thirty parasitoid species are associated to these galls. Most of them is generalist and solitary. Hyperparasitoidism is common. The trophic relations among gall makers and parasitoids are presented.
