          Abstract

          Our goal was describe the gall richness through the characterization of their external shapes and occurrence patterns in their host plants from Parque Estadual da Serra do Cabral. In a universe of 34 families, 64 genera and 89 plant species, 47 gall-inducing insects in 21 families, 32 genera and 39 host plant species were recorded. The families, which hosted higher gall richness, were those with highest abundance. Asteraceae represented 33% of the species collected followed by Malpighiaceae 8% and Fabaceae 8%, each one concentrating 25%, 19% and 8% of gall-inducing insects, respectively. The organ most attacked was the leaf (51%), followed by the stem (42%) and the terminal branch (4%). Ninety-six percent (96%) of galls were glabrous. Only 25.5% of the galls described in our study have been already recorded in previous studies, reinforcing the need to increase the sampling effort toward a better understanding of the richness, distribution, and natural history of gall-inducing insects from Brazil.

          Objetivo deste estudo foi descrever a riqueza de morfotipos de galha por meio da caracterização de suas formas e os padrões de ocorrência em suas plantas hospedeiras no Parque Estadual da Serra do Cabral. Num universo de 34 famílias, 64 gêneros e 89 espécies de plantas, foram registradas 47 espécies de galhas induzidas por insetos em 21 famílias, 32 gêneros e 39 espécies de plantas hospedeiras. As famílias que concentraram maior riqueza de insetos galhadores foram as famílias mais abundantes. A família Asteraceae representou 33% das espécies coletadas, seguida das Malpighiaceae 8% e Fabaceae 8%, cada uma concentrando 25%, 19% e 8% das espécies de insetos galhadores, respectivamente. O órgão mais atacado foi a folha (51%), seguido do caule (42%) e ramo terminal (4%). Noventa e seis por cento (96%) das galhas foram glabras. O fato de apenas 25% das galhas descritas neste estudo já terem sido registradas em trabalhos prévios, reforça a necessidade em aumentar o esforço amostral na direção de um maior conhecimento sobre a riqueza, distribuição e história natural dos insetos indutores de galhas no Brasil.

          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.

            Are gall midge species (Diptera, Cecidomyiidae) host-plant specialists?

            Despite the speciose fauna of gall-inducing insects in the Neotropical region, little is known about their taxonomy. On the other hand, gall morphotypes associated with host species have been extensively used as a surrogate of the inducer species worldwide. This study reviewed the described gall midges and their galls to test the generalization on the use of gall morphotypes as surrogates of gall midge species in the Brazilian fauna. We compiled taxonomic and biological data for 196 gall midge species recorded on 128 host plant species. Ninety two percent of those species were monophagous, inducing galls on a single host plant species, whereas only 5.6% species were oligophagous, inducing galls on more than one congeneric host plant species. Only four species induced galls on more than one host plant genus. We conclude that gall morphotypes associated with information on the host plant species and attacked organs are reliable surrogates of the gall-inducing species.

              Insect galls from Serra de São José (Tiradentes, MG, Brazil)

              One hundred thirty-seven morphotypes of insect galls were found on 73 plant species (47 genera and 30 families) in Serra de São José, in Tiradentes, MG, Brazil. Fabaceae, Myrtaceae, Asteraceae, and Melastomataceae were the plant families that supported most of the galls (49.6% of the total). Galls were mostly found on leaves and stems (66.4% and 25.5%, respectively). Galls were induced by Diptera, Lepidoptera, Coleoptera, Hemiptera (Sternorrhyncha), Hymenoptera, and Thysanoptera. The majority of them (73.7%) were induced by gall midges (Cecidomyiidae: Diptera). Besides the gall inducers, other insects found associated with the galls were parasitoids (Hymenoptera), inquilines (Coleoptera, Lepidoptera, Diptera, and Hemiptera), and predators (Diptera).
