Drosofilídeos e seus himenópteros parasitoides em Coffea arabica L.

The objective of this study was to evaluate the occurrence of Drosophilidae and their parasitoids in coffee fruits in Cravinhos, SP, Brazil. The fruits were collected directly from the tree, and a portion was exposed under the canopy. Fifty-nine drosophilid pupae were collected in all, of which 31 adults (including two Ganaspis exemplars) emerged. The survival rate of all pupae was 49.2%. Thirty-five drosopholid pupae were obtained from the fruit trees, 24 of which later emerged, three different species: Zaprionus indianus Gupta, Drosophila nebulosa Sturtevant and D. simulans Sturtevant. From the fruits under the canopy of plants were obtained 24 pupae of four different species: Z. indianus, D. cardini Sturtevant, D. immigrans Sturtevant and D. willistoni Sturtevant. The emergence of two Ganaspis sp. (Hymenoptera: Figitidae) examples, with a parasitism rate of 8.3%, was also observed. Half of the drosophilids collected are introduced species and represented 79% of the adults emerged. Associations between Z. indianus, D. cardini, D. immigrans, D. nebulosa, D. simulans and D. willistoni and the coffee crop are reported herein.Objetivou-se neste estudo avaliar a ocorrência de drosofilídeos e de seus parasitoides em frutos de café em Cravinhos, SP. Foram coletados frutos em estádio de cereja diretamente das plantas e parte deles foi exposta em bandejas sob suas copas, simulando frutos caídos no solo. Foram obtidos 59 pupários de drosofilídeos, dos quais emergiram 29 adultos (viabilidade pupal = 49,2%) e dois exemplares de Ganaspis sp. (Hymenoptera: Figitidae), o que totalizou 31 adultos emergidos. A partir dos frutos coletados diretamente das plantas, foram obtidos 35 pupários, dos quais emergiram 24 drosofilídeos pertencentes a três espécies: Zaprionus indianus Gupta, Drosophila nebulosa Sturtevant e D. simulans Sturtevant. A partir dos frutos mantidos sob a copa das plantas, foram obtidos 24 pupários, de onde emergiram cinco drosofilídeos pertencentes a quatro espécies: Z. indianus, D. cardini Sturtevant, D. immigrans Sturtevant e D. willistoni Sturtevant; também foi observada a emergência de dois exemplares de Ganaspis sp., o que resultou em taxa de parasitismo de 8,3%. A metade das espécies de drosofilídeos encontradas neste estudo é introduzida e representaram 79% do total de adultos emergidos. São relatadas as associações de Z. indianus, D. cardini, D. immigrans, D. nebulosa, D. simulans e D. willistoni com a cultura do cafeeiro

Registro de lepidóptero desfolhador em andirobeira no estado do Acre e parasitoides associados

The crabwood tree, Carapa guianensis Aublet, is a tree of significant socioeconomic importance especially for extractive communities in the North of Brazil, which exploit wood and, mainly, oil extracted from seeds. In January 2016, intense defoliation was observed in crabwood trees located in the municipality of Rio Branco, Acre state, Brazil, caused by lepidopteran caterpillars. Twenty pupa specimens were collected and placed in a screened cage to obtain adults. Five female moths emerged, which were identified as Acharia sp. (Lepidoptera: Limacodidae). In addition, two species of parasitoids were also captured, identified as Baryceros sibine (Cameron) (Hymenoptera: Ichneumonidae) and Conura sibinecola (Blanchard) (Hymenoptera: Chalcididae). Thus, the first record of Acharia sp. in crabwood tree in the state of Acre, as well as the first records of the two species of parasitoids associated with Acharia in the state of Acre, as well as in Brazil.A andirobeira, Carapa guianensis Aublet, é uma árvore de expressiva importância socioeconômica, especialmente para as comunidades extrativistas na região Norte do Brasil, as quais exploram a madeira e, principalmente, o óleo extraído das sementes. Em janeiro de 2016, foi observado um intenso desfolhamento em andirobeiras localizadas no município de Rio Branco, Acre, causado por lagartas de lepidópteros. Vinte espécimes em fase de pupa foram coletados e acondicionados em gaiola telada, visando a obtenção de adultos. Emergiram cinco mariposas fêmeas, as quais foram identificadas como Acharia sp. (Lepidoptera: Limacodidae). Ademais, também foram capturadas duas espécies de parasitoides, identificadas como Baryceros sibine (Cameron) (Hymenoptera: Ichneumonidae) e Conura sibinecola (Blanchard) (Hymenoptera: Chalcididae). Assim, se faz o primeiro registro de Acharia sp. em andirobeira no estado do Acre, bem como os primeiros registros das duas espécies de parasitoides associados a Acharia no estado do Acre, bem como no Brasil

Diversidade e métodos de amostragem de Hymenoptera na cultura da melancia no semiárido

The aims of this study were to identify the Hymenoptera fauna associated with watermelon crops and assess the influence of Pitfall, Moericke and McPhail traps in capturing these insects in the semiarid environment of the state of Rio Grande do Norte, Brazil. The survey was conducted between the months of August and September, 2011, in a commercial watermelon cv Crimson Sweet production area. The collection of the Hymenoptera was conducted weekly during the crop cycle. To capture the insects, three types of traps were used, Pitfall, Moericke and McPhail, in densities 20, 20 and 1 trap per hectare, respectively. The traps were installed seven days after seeding and maintained in the area until harvest. A total of 3,123 Hymenoptera were collected, belonging to 10 superfamilies, and 24 families. Formicidae was the most representative, with a total relative abundance of 54.43%, followed by Apidae with 17.96%. The presence of 18 families of parasitoids (18.89%) was also observed, notably Platygastridae (6.60%), Encyrtidae (2.79%), Chalcididae (2.56%), Mymaridae (2.56%), Pompilidae (1.15%) and Trichogrammatidae (1.09%). The occurrence of predators from the families Crabronidae (6.34 %), Vespidae (2.24 %) and Sphecidae (0.10%) is noteworthy. Among the traps, Moericke captured the greatest diversity of Hymenoptera (24 families), followed by Pitfall (11 families) and McPhail (seven families) traps. © 2016, Sociedade de Olericultura do Brasil.

This study reports sap beetles from fruits of a coffee crop in Cravinhos, SP, Brazil. Fruits were collected directly from plants and, in laboratory, from the fruits at the cherry state we obtained 20 adults of three species: Carpophilus nepos Murray, 1864,Colopterus niger Murray, 1864 and Nitops sordidus Erichson, 1847. This is the first report of association between these insects and coffee fruits.Nesse estudo são relatados os nitidulídeos obtidos de frutos de café, provenientes de uma cultura estabelecida em Cravinhos, SP, Brasil. Entre março e junho de 2008 foram coletadas amostras de frutos de café diretamente das plantas e, emlaboratório, foram separados aqueles em estádio de cereja, a partir dos quais foram obtidos 20 adultos de nitidulídeos, de três espécies: Carpophilus nepos Murray, 1864, Colopterus niger Murray, 1864 e Nitops sordidus Erichson, 1847.

Comparative abundance and diversity of Dryininae (Hymenoptera, Dryinidae) in three savannah phytophysiognomies in southeastern Brazil, under three sampling methods

Comparative abundance and diversity of Dryininae (Hymenoptera, Dryinidae) in three savannah phytophysiognomies in southeastern Brazil, under three sampling methods. This study aimed to assess the abundance and diversity of Dryininae in riparian vegetation, Brazilian savannah, and savannah woodland vegetation at the Estação Ecológica de Jataí, in Luiz Antônio, State of São Paulo, Brazil, by using Moericke, Malaise, and light traps. The sampling was carried out from December 2006 to November 2009, and 371 specimens of Dryininae were caught, with the highest frequencies in spring and summer. Fourteen species of Dryinus Latreille, 1804 and one of Thaumatodryinus Perkins, 1905 were identified. The highest frequencies of Dryinus in the riparian vegetation differed significantly from those obtained in the Brazilian savannah and savannah woodland vegetation. In the riparian vegetation, the highest number of Dryinus was collected using light traps and the interactions between abundance and the collection method used were significant. The number of specimens of Dryinus collected in the Brazilian savannah and savannah woodland vegetation using Malaise traps did not differ significantly from those obtained using Moericke traps. Males significantly outnumbered females in the sex ratio of Dryinus. The species diversity of Dryinus based on females collected using Malaise traps was high in the Brazilian savannah. Furthermore, high species richness of female Dryinus was observed in riparian vegetation (six species) and Brazilian savannah (five). The light trap was the most successful method for sampling diversity of Dryininae
