“…Galls in roots were recorded only in the epiphytic species Philodendron surinamense (Araceae), occurring in adventitious roots. In general, root-induced insect galls are poorly recorded, although they occur in roots of epiphytic species of other families such as Orchidaceae and Polypodiaceae (TANOUE et al, 2004;MAIA & SANTOS, 2015). Underground roots aggregate gallers from other organisms, such as bacteria and nematodes (MANI, 1964) and are often the focus of agronomic science studies.…”

The restingas are coastal ecosystems over the sandy Quaternary plains. Their vegetation present flora and structure conditioned mainly by edaphic factors. They vary from grasslands, shrub lands up to woody forests. Their environmental conditions, such as water stress and high solar irradiance, may be associated to a high richness of galling. This study aims to identify the insect-plant interactions of the gall type, in a shrub-tree restinga formation at the Acaraí State Park, situated in São Francisco do Sul, Santa Catarina State. The survey was conducted in four plots of 250 x 5 m (5,000 m²) of the PELD/PPBio module, with a sample effort of 32 hours. There were found 56 morphospecies of galls in 31 species of host plants. Lauraceae, Myrtaceae, Melastomataceae, Nyctaginaceae and Calophyllaceae showed the highest number of interactions. Guapira opposita (Nyctaginaceae) and Calophyllum brasiliense (Calophyllaceae) were the major super-hosts. There was a predominance of isolated globoid galls on leaves, induced by Diptera -Cecidomyiidae. Galls on stems were less abundant. The focus of this inventory was restricted to the aerial parts of the plants, which limited the galls records on roots, for which there were records only in adventitious roots of the epiphyte Philodendron surinamense. The richness of galls seems to be proportional to the richness of plant species in this restinga formation. Keywords: Cecidomyiidae; coastal vegetation; plant-insect interaction; super-hosts. RESUMOAs restingas são ecossistemas costeiros que ocupam as planícies quaternárias arenosas. Sua vegetação apresenta flora e estrutura condicionada por fatores edáficos em maior grau. Variam de formações herbáceas, arbustivas, arbustivo-arbóreas a florestas. Suas características ambientais estressantes, como a baixa disponibilidade hídrica e a alta radiação solar, propiciam uma elevada riqueza de insetos galhadores. O objetivo deste estudo foi reconhecer as interações inseto-planta, do tipo galha, na formação arbustivo-arbórea da restinga do Parque Estadual Acaraí, situado em São Francisco do Sul, Santa Catarina. O levantamento foi realizado em quatro parcelas de 250 x 5 m (5.000 m²) do módulo PELD/ PPBio, com esforço amostral de 32 horas. Encontraram-se 56 morfoespécies de galhas em 31 espécies de plantas hospedeiras. As famílias com maior número de interações foram Lauraceae, Myrtaceae, Melastomataceae, Nyctaginaceae e Calophyllaceae. As espécies Guapira opposita (Nyctaginaceae) e Calophyllum brasiliense (Calophyllaceae) foram as principais super-hospedeiras. Houve predominância de galhas globoides isoladas em folhas, induzidas por Diptera -Cecidomyiidae. Galhas em caules foram menos abundantes. O foco do inventário restringiu-se às partes aéreas das plantas, o que limitou o registro de galhas em raízes, sendo registradas apenas em raízes adventícias da epífita Philodendron surinamense. A riqueza de galhas parece ser proporcional à riqueza de espécies vegetais nessa formação de restinga. Palavras-chave: Cecidomyiidae; interação inseto-...

“…In Brazil, galls have been recorded on 16 of the 1,144 fern species cataloged (Flora do Brasil 2020), a ratio of 0.013. However, the inducer was identified at species level in only three gall morphotypes from three fern species (Maia & Santos 2011, 2015. To date, no lycophyte species have been recorded as hosting galls in Brazil and Costa Rica.…”

“…More recently, Maia & Santos (2011, 2015 recorded two stem gall morphotypes in Microgramma vacciniifolia, one ellipsoid-shaped (fusiform) induced by the microlepidoptera Tortrimosaica polypodivora ( Figure 1A), and the other spherical (globoid) and induced by the Cecidomyiidae: Diptera Primadiplosis microgrammae ( Figure 1B). Two species of parasitoid wasps (Hymenoptera) were also observed: Torymidae and Tetrastichinae (Eulophidae).…”

Galls are neo-formed plant structures induced by species-specific interaction between an inducing organism and a host plant. Lycophytes and ferns are two distinct plant lineages historically lumped together as pteridophytes. A number of authors suggest low gall frequency in lycophytes and ferns, compared to angiosperms. This study aimed at compiling an updated overview of fern galls in Brazil, providing information on hosts, gall-inducing organisms and associated fauna. The synopsis was compiled using existent data and by updating scientific names and gathering new information obtained by the authors in fieldwork. To date, galls have been recorded on 16 fern species but none on lycophytes. However, the inducer was identified at species level in only three gall morphotypes from three fern species, with a doubtful inducer for Pteridium sp. Galls are induced by mites (Eriophyidae) and insects of the orders Diptera, Lepidoptera, Thysanoptera, and Hemiptera, Cecidomyiidae (Diptera) being the most frequent galler insect. Keywords: Pteridophytes, lycophytes, galls, Neotropical, Cecidomyiidae. Sinopse de galhas em samambaias no BrasilResumo: Galhas são estruturas vegetais neoformadas induzidas por interações espécie-específicas entre um organismo indutor e uma planta hospedeira. Licófitas e samambaias são duas linhagens de plantas historicamente classificadas juntas como pteridófitas. Diversos autores sugerem que há uma baixa frequência de galhas em licófitas e samambaias, em comparação com as angiospermas. Este trabalho tem como objetivo fornecer um panorama atualizado sobre as galhas em samambaias no Brasil, disponibilizando informações sobre espécies hospedeiras, galhadores e fauna associada. A sinopse foi realizada compilando-se os dados existentes, atualizando os nomes científicos e agregando informações novas obtidas pelos autores em trabalhos de campo. Até o momento, foram registradas galhas em 16 espécies de samambaias e nenhum registro em licófitas. Contudo, em apenas três morfotipos de galhas, de três espécies de samambaias, o indutor foi identificado a nível de espécie, com um indutor duvidoso para Pteridium sp. As galhas são induzidas por ácaros (Eriophyidae) e insetos das ordens: Diptera, Lepidoptera, Thysanoptera, Hemiptera, sendo Cecidomyiidae (Diptera) o galhador mais frequente.

“…Santos et al, 2011;Maia and Silva, 2016). Comparatively few galls have been reported on ferns (e.g., Houard, 1933;Kraus et al, 1993;Balick et al, 1978;Maia and Santos, 2015), although ferns are the second largest group of vascular plants and are especially abundant in tropical forest understories (Sharpe et al, 2010). Consequently, ferns might have been underestimated as host plants of galling insects, due to the lack of adequate sampling (Mehltreter, 2010).…”
