“…The families that added the most gall (51.8%) in the formation of restinga studied also stand out in the flora of the PEA as those with the greatest species richness, or with species of greater representativeness in the community structure of the restinga formations of this park (MELO JÚNIOR & BOEGER, 2015). In this way, the greater diversity presented or the greater abundance of a given taxon can be positively related to the supply of host plants (MENDONÇA JR., 2007;ARAÚJO, 2011). In the herbaceous formation of the PEA, 15 morphospecies of gall were recorded, occurring in 8 species of host plants (ARRIOLA et al, 2015), a number considerably lower than that recorded in this study.…”

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-...

“…The main reason for the great gall richness hosted by these families is its high number of plant species (Mendonça et al, 2008;Araújo et al, 2014), since there is a positive correlation between the number of plant species and galling species (Araújo, 2011). In the present study, Fabaceae and Asteraceae hosted insect galls mainly in the savanna.…”

“…We performed four bi-monthly samplings between December 2009 and June 2010 in the two vegetation types. The insect gall sampling was done through active searches, with duration of 01h30min, along four fixed transects, being two in each vegetation type (Araújo et al, 2011). In each transect, we sampled every plant that hosted insect galls, including trees, shrubs and herbs.…”

“…Insect galls were classified into morphotypes using the host plant species and external morphology (organ of occurrence, form, colour, pubescence and size) (Araújo et al, 2011). Gall morphotypes were used as a surrogate for species of gall-inducing insects because there is a consensus in the literature about host-specificity and morphologicalfidelity of insect galls (reviewed in Carneiro et al, 2009).…”

“…Plants under environmental stress condition of xeric habitats tend to accumulate higher concentrations of secondary metabolites (Araújo et al, 2014). Because galling insects can sequester the plant secondary metabolites during gall formation as a protection mechanism against natural enemies (Cuevas-Reyes et al, 2004, 2011Gonçalves-Alvim & Fernandes, 2001), evidences pointed that this high defense investment of xeric habitat plants favors insect gall occurrence (Fernandes & Price, 1988;Gonçalves-Alvim et al, 2001;Lara et al, 2002).…”

ABSTRACT. We investigated the insect gall distribution along savanna (xeric) and forest (mesic) vegetation in the Floresta Nacional de Silvânia, Goiás, Brazil. We tested if the insect gall diversity is higher in the xeric vegetation than in the mesic vegetation, as predicted by the hygrothermal stress hypothesis. The insect gall fauna was surveyed between December 2009 and June 2010 in two transects established each vegetation type. In total we found 186 insect gall morphotypes, distributed on 35 botanical families and 61 plant species. Cecidomyiidae (Diptera) induced the most insect galls (34.1%), and the plant family Fabaceae had the greatest richness of insect gall morphotypes (18). We recorded 99 insect gall morphotypes in the forest and 87 morphotypes in the savanna vegetation, being that none insect gall morphotype occurred in both habitats. We found that the insect gall richness and abundance did not diff er between forest and savanna transects. On the other hand, the estimated insect gall richness was higher in the forest than in the savanna. Our fi ndings contrary the hygrothermal stress hypothesis possibly because forest habitats have higher plant architecture complexity and occurrence of super-host taxa than the savanna habitats.KEYWORDS. Cecidomyiidae, Cerrado, Fabaceae, plant-insect interaction.RESUMO. Distribuição de galhas de insetos em habitats xéricos e mésicos da Floresta Nacional de Silvânia, Brasil. Foi inventariada a distribuição de galhas de insetos ao longo de vegetações savânicas (xéricas) e fl orestais (mésicas) na Floresta Nacional de Silvânia, Goiás, Brasil. O estudo testou se a diversidade de insetos galhadores é maior na vegetação xérica do que na vegetação mésica, como predito pela hipótese do estresse higrotermal. A fauna de galhadores foi amostrada entre dezembro de 2009 e junho de 2010 em dois transectos estabelecidos em cada tipo de vegetação. No total foram encontrados 186 morfotipos de galhas de insetos, distribuídos em 35 famílias e 61 espécies de plantas. Cecidomyiidae (Diptera) induziu a maioria das galhas de insetos (34,1%) e a família Fabaceae teve a maior riqueza de morfotipos de galhas (18). Foram registrados 99 morfotipos de galhas de insetos na fl oresta e 87 morfotipos no cerrado, sendo que nenhum morfotipo de galha ocorreu em ambos os habitats. A riqueza e a abundância de galhas de insetos não diferiram entre os transectos de fl oresta e cerrado. Por outro lado, a riqueza estimada de galhas de insetos foi maior na fl oresta do que no cerrado. Esses resultados contrariam a hipótese do estresse higrotermal possivelmente devido aos habitats fl orestais apresentarem maior complexidade arquitetônica das plantas e ocorrência de táxons super-hospedeiros do que os hábitats savânicos.PALAVRAS-CHAVE. Cecidomyiidae, Cerrado, Fabaceae, interação inseto-planta.
