          Abstract

          An inventory of gall inducing insects and their host plants in the Atlantic forest of Pernambuco, northeastern Brazil is presented. Samples of galls and their host plants were taken in six fragments of Atlantic forest. One hundred thirty-six different morphotypes of insect galls on 79 host plant species belonging to 35 plant families and 53 genera were recorded. The host plant families most attacked by galling insects were: Lecythidaceae, Myrtaceae, and Nyctaginaceae. The most frequent galling taxa were Diptera of the Cecidomyiidae family (95%), followed by Lepidoptera and Coleoptera. Galls occurred most frequently on leaves and stems, had globoid and elliptical shapes, green color and absence of trichomes on the external walls. The data indicate an intermediary richness of gall inducing insects when compared to other Brazilian Atlantic forests.

          Um inventário de insetos galhadores e suas plantas hospedeiras foi realizado para a Mata Atlântica de Pernambuco, Nordeste do Brasil. As galhas e suas plantas hospedeiras foram amostradas em seis fragmentos de Mata Atlântica. Cento e trinta e seis diferentes morfotipos de galhas de insetos em 79 espécies de plantas hospedeiras pertencentes a 35 famílias de plantas e 53 gêneros foram registrados. As famílias de plantas mais atacadas por insetos galhadores foram: Lecythidaceae, Myrtaceae e Nyctaginaceae. O grupo mais frequente de galhador foi Diptera da família Cecidomyiidae (95%), seguido por Lepidoptera e Coleoptera. Galhas ocorreram mais frequentemente sobre as folhas e caules, possuíam um formato globoso e formas elípticas, de cor verde e ausência de tricomas nas paredes externas. Os dados indicam uma riqueza intermediária de insetos indutores de quando comparado com outras florestas atlânticas brasileiras.

            The gall midges (Diptera, Cecidomyiidae) from three restingas of Rio de Janeiro State, Brazil

            One hundred and eight species of Cecidomyiinae (Cecidomyiidae) were found in association with 53 species of plant distributed among 42 genera and 32 families at restingas of Barra de Maricá, Itaipuaçu and Carapebus. Ninety four gall midge species were cecidogenous, four predaceous, five inquilinous of galls and five were free living. Galling species were associated with 47 plant species belonging to 36 genera and 28 families. The majority of the galls occurred on the leaves (N = 63); 13 on buds; nine on inflorescence, closed flower or flower peduncle; three on fruits and one on tendril. Myrtaceae were the richest plant family in number of galls followed by Burseraceae, Nyctaginaceae, Sapotaceae, Erythroxylaceae, Malpighiaceae and Solanaceae. New records of host plants and localities were recorded. Seventy nine Cecidomyiinae species were found at Restinga of Barra de Maricá, 64 at Carapebus and 41 at Itaipuaçu. Sorensen's index revealed that the restingas of Barra de Maricá and Itaipuaçu ate more similar in Cecidomyiinae fauna, confirming a positive relation between geographical proximity and fauna similarity.
