ABSTRACT

This study characterizes the diversity of Sisyridae in an area of riparian forest (21°36'47"S; 47°49'4"W) at the Estação Ecológica de Jataí, in the municipality of Luiz Antônio, State of São Paulo, Brazil. The geographic ranges of Climacia carpenteri Parfin & Gurney, 1956 and Sisyra panama Parfin & Gurney, 1956 are expanded to include the State of São Paulo.

ABSTRACT

In this study, the Gasteruptiidae (Hymenoptera, Evanioidea) collected in three environments at the Department of Rocha, in Eastern Uruguay, were documented based on a survey carried out with Malaise traps between December 2014 and December 2016. During the samplings, four species of Gasteruption Latreille, 1796 were captured, being 14 females and three males of Gasteruption brachychaetun Schrottky, 1906; eight females and five males of Gasteruption brasiliense (Blanchard, 1840); one female of Gasteruption helenae Macedo, 2011 and one female of Gasteruption brandaoi Macedo, 2011. Gasteruption brachychaetun, G. helenae and G. brandaoi are recorded by the first time from Uruguay.

ABSTRACT

In this study, the Gasteruptiidae species found at the Estação Ecológica de Jataí (EEJ), in Luiz Antonio, São Paulo, Brazil, were documented, based on a survey carried out with Malaise, Moericke and light traps that lasted for three years, between January 2007 and December 2009. During the samplings at EEJ, 13 female specimens of Gasteruption Latreille, 1796 were captured: six of G. bispinosum Kieffer, 1904, six of G. brasiliense (Blanchard, 1840) and a single specimen of G. helenae Macedo, 2011 that is the first record for São Paulo state.

ABSTRACT

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.

ABSTRACT

Seasonality of Pelecinus polyturator (Drury) (Hymenoptera, Pelecinidae) in the Atlantic Rainforest of São Paulo State, Brazil. A survey of the parasitoid wasp Pelecinus polyturator (Drury, 1773) (Hymenoptera, Pelecinidae) was carried out with five Malaise traps/area in five areas in the Atlantic Rainforest of São Paulo State, Brazil, between November 2009 and October 2010. The sampling effort in each locality amounted to 1,825 trap-days. Data were obtained from a total of 317 exemplars of P. polyturator, corresponding to 108 females and 209 males. The average sex ratio of the studied population was 0.52. The highest occurrence of P. polyturator was observed between November and March with frequency peak in January; about 95% of the specimens studied were captured at altitudes close to 1,000 m above sea level.

ABSTRACT

Três novas espécies de Prodecatoma obtidas a partir de galhas em frutos de Psidium cattleianum Sabine e Psidium cinereum Mart. ex DC.(Myrtaceae) são descritas a partir de material obtido no Paraná e Rio Grande do Sul, Brasil. Duas das novas espécies, Prodecatoma carpophaga sp. nov. e Prodecatoma petrodoma sp. nov. são descritas como indutoras das galhas. Prodecatoma ferruginea sp. nov. e Prodecatoma spermophaga Costa-Lima são apontadas como inquilinas das galhas ou parasitóides. São incluídos também comentários sobre a morfologia macroscópica da galha e a biologia das vespas.
