          Abstract

          Resumo Eugenia dysenterica é uma espécie nativa do Cerrado com potencial para exploração econômica em função do seu uso na alimentação. No entanto, estudos são necessários para possibilitar a domesticação da espécie em plantio comercial. Atualmente, os frutos são obtidos a partir do extrativismo em áreas do Bioma Cerrado. A artropodofauna associada à Eugenia dysenterica é praticamente desconhecida. Assim, o presente estudo teve como objetivo avaliar a artropodofauna associada às folhas de Eugenia dysenterica. Avaliamos quinzenalmente a artropodofauna em plantas de Eugenia dysenterica na coleção de germoplasma ex situ da Escola de Agronomia, UFG. Para tanto, três ramos do terço médio foram amostrados em 16 plantas. Posteriormente, sete folhas/ramo foram selecionadas e analisadas sob microscópio estereoscópio. As cochonilhas foram os artrópodes mais abundantes em Eugenia dysenterica. A presença de folhas novas no mês de outubro coincidiu com a eclosão das ninfas da cochonilha Ceroplastes acutus e com o aparecimento de galhas foliares causadas por dípteros. A superfamília Coccoidea e a família Aleyrodidae foram classificadas como superabundantes e superfrequentes. Duas famílias de Thysanoptera foram encontradas: Thripidae e Phlaeothripidae. Com relação aos ácaros, as espécies fitófagas foram as mais abundantes, seguidas pelos ácaros predadores. As famílias Phytoseiidae e Tenuipalpidae foram as mais representativas nas amostras. Aleirodídeos, dípteros e a cochonilha Ceroplastes acutus estão associados à emissão de novas folhas da cagaiteira. Este é o primeiro relato de ocorrência de espécies de ácaros, tripes e da cochonilha Ceroplastes acutus em Eugenia dysenterica.

          Abstract Eugenia dysenterica is a native species of the Cerrado biome which has potential for economic exploitation due to its economic importance in food. However, further studies are crucial to enable the domestication of this species in commercial plantation. Actually, the fruits are obtained by extractivism in area of the Cerrado vegetation. The arthropodfauna associated to Eugenia dysenterica is practically unknown. Thus, the present study aimed to evaluate the arthropodofauna associated with leaves of Eugenia dysenterica. We evaluated the arthropodfauna biweekly in Eugenia dysenterica plants in the collection of ex situ germoplasm of ‘Escola de Agronomia’, UFG. Three branches of the middle third were sampled in 16 plants. Seven leaves/branch were selected and analyzed under stereomicroscope. Cochineals were the most abundant arthropods in Eugenia dysenterica. The presence of new leaves on the plants, October, coincided with the hatching of the nymphs of the cochineal Ceroplastes acutus and the appearance of leaf galls caused by Diptera. The superfamily Coccoidea and the family Aleyrodidae were classified as superabundant and superfrequent. Two families of Thysanoptera were reported: Thripidae and Phlaeothripidae. In relation to plant mites, phytophagous species were the most abundant ones, followed by predatory mites. Families Phytoseiidae and Tenuipalpidae were the most representative in the samples. Aleyrodidae, Diptera and cochineal Ceroplastes acutus are associated with the emission of new leaves of Cagateira. This is the first report of the occurrence of mite species, thrips and Ceroplastes acutus in Eugenia dysenterica.

            Diversity of insect galls associated with coastal shrub vegetation in Rio de Janeiro, Brazil

            ABSTRACT Surveys in the coastal sandy plains (restingas) of Rio de Janeiro have shown a great richness of galls. We investigated the galling insects in two preserved restingas areas of Rio de Janeiro state: Parque Estadual da Costa do Sol and Reserva Particular do Patrimônio Natural Fazenda Caruara. The collections were done each two months, from June 2011 to May 2012. We investigated 38 points during 45 minutes each per collection. The galls were taken to the laboratory for rearing the insects. A total number of 151 insect galls were found in 82 plant species distributed into 34 botanic families. Most of the galls occurred on leaves and the plant families with the highest richness of galls were Myrtaceae and Fabaceae. All the six insect orders with galling species were found in this survey, where Cecidomyiidae (Diptera) was the main galler group. Hymenoptera and Thysanoptera were found as parasitoids and inquilines in 29 galls. The richness of galls in the surveyed areas reveals the importance of restinga for the composition and diversity of gall-inducing insect fauna.
