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.

e realizó un estudio de Monomachus (Hymenoptera, Monomachidae) con cinco trampas Malaise por área, en cinco áreas del bosque lluvioso Atlántico en el Estado de São Paulo, Brasil, entre octubre de 2009 y diciembre de 2011. El esfuerzo de muestreo en todas las localidades ascendió a 9.900 trampas-día. Se obtuvo un total de 304 ejemplares de Monomachus: 66 hembras y 238 machos. La mayor ocurrencia de Monomachus fue entre junio y septiembre, con pico de frecuencia en julio, siendo más frecuentes en el Parque Estadual Morro do Diabo (PEMD) (350 m sobre el nivel del mar), donde el esfuerzo de muestreo para capturar cada ejemplar fue de 65,1 trampas-día. Del total de hembras de Monomachus capturadas del Parque Estadual Intervales, Parque Estadual da Serra do Mar/Núcleo Santa Virgínia (PESM/NSV), PEMD y Estação Ecológica Juréia Itatins entre diciembre 2009 y diciembre 2010 se reconocieron dos especies: M. fuscator (N = 58 / 87,9 %) y M. cubiceps (8,0 / 12,1 %). En muestreos adicionales en 2011 en PESM/NSV se obtuvieron dos ejemplares de M. klugii sólo registrada para el Estado de Río de Janeiro, y ahora su distribución se extiende al Estado de São Paulo.

A survey of Monomachus (Hymenoptera, Monomachidae) was carried out with five Malaise traps/area in five areas of Atlantic Rainforest in São Paulo State, Brazil. The sampling effort in all localities amounted to 9,900 traps-day. Data were obtained from a total of 304 exemplars of Monomachus: 66 females and 238 males. The highest occurrence of Monomachus was observed between June and September with a frequency peak in July, and they were most frequent in Parque Estadual Morro do Diabo (PEMD) (350 m above sea level), where the sampling effort to catch each exemplar was 65.1 traps-day. From the sample of females of Monomachus captured in the Parque Estadual Intervales, Parque Estadual da Serra do Mar/Núcleo Santa Virgínia (PESM/NSV), PEMD and Estação Ecológica Juréia Itatins, between December 2009 and December 2010, two species were recognized: M. fuscator (N = 58 / 87.9 %) and M. cubiceps (8 / 12.1 %). In additional samplings in 2011 at PESM/NSV two exemplars of M. klugii recorded only from Rio de Janeiro State, Brazil were obtained, showing that its distribution has extended to São Paulo State.

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.

El objetivo de este estudio fue reportar los Orgilinae obtenidos en Coffea arabica cv. Obatã, en Cravinhos, São Paulo, Brasil, evaluar la fluctuación poblacional de Orgilus niger, así como correlacionar su población con los métodos de muestreo, con las poblaciones de Leucoptera coffeella, pluviosidad y media de las temperaturas máximas y mínimas. Los orgilinos fueron recolectados semanalmente entre mayo de 2005 y abril de 2007 con trampas Moericke y luminosa. Las siguientes especies fueron identificadas: O. niger (757 ejemplares; 88,0% del total colectado), Orgilus sp. 1 (71; 8,3%) y Stantonia longicornis (32; 3,7%). Las mayores frecuencias de los orgilinos ocurrieron entre mayo de 2005 y abril de 2006 (693; 80,6%) y para O. niger entre mayo y octubre de 2005, con un pico entre agosto y septiembre de 2005. Las trampas Moericke capturaron la totalidad de los ejemplares de O. niger, S. longicornis y la mayoría de los Orgilus sp. 1. Las trampas Moericke instaladas en la altura del tercio inferior de las plantas capturaron el mayor promedio de O. niger, el cual difirió significativamente de las instaladas en el tercio medio. Entre mayo de 2005 y abril de 2006, las correlaciones entre la población de O. niger y el número de larvas vivas y galerías de L. coffeella disponibles para parasitismo fueron positivas y significativas y, negativas y significativas con la pluviosidad y las temperaturas mínima y máxima, lo que indica que periodos de sequía y de menor temperatura en el año favorecen el aumento de la población de L. coffeella y de su parasitoide O. niger.

The aim of this study was to document the Orgilinae species found in Coffea arabica L. at Cravinhos, at São Paulo State, Brazil; to evaluate the population fluctuation of Orgilus niger, and to correlate it population with the sampling methods employed, with populations of Leucoptera coffeella, rainfall, and the average maximum and minimum temperatures. Orgilinids were collected weekly between May 2005 and April 2007 with Moericke and light traps. The following species were identified: O. niger (757 specimens; 88.0% of the total collected), Orgilus sp. 1 (71; 8.3%), and Stantonia longicornis (32; 3.7%). The highest frequency of Orgilinae was recorded between May 2005 and April 2006 (693; 80.6%), and O. niger between May and October 2005, with a peak population between August and September 2005. Moericke traps captured all the specimens of O. niger, S. longicornis and most Orgilus sp. 1; traps installed at the height of the lower third of the plants captured the highest average of O. niger, which differed significantly from those installed in the middle third. Between May 2005 and April 2006, the correlations between the population of O. niger and the number of larvae and mines of L. coffeella available for parasitism were positive and significant and negative and significant with the rainfall and minimum and maximum temperatures, indicating that periods of drought and lower temperature in the year favor the increase of the population of L. coffeella and its parasitoid O. niger.

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.

Este estudio tuvo como objetivo caracterizar los Hemerobiidae (Neuroptera) asociados al "Cerrado" sensu stricto y bosque de galería, en el estado de Minas Gerais, Brasil. El muestro de hemeróbidos se realizó quincenalmente con auxilio de trampas Malaise entre noviembre de 2003 y octubre de 2004. En las dos áreas de estudio se capturaron 181 ejemplares de hemeróbidos de cinco especies. Las especies: Nusalala tessellata, Megalomus impudicus, Hemerobius bolivari y Notiobiella sp., se encontraron en ambos sitios; la quinta especie Sympherobius sp. se encontró únicamente en Pedra do Indaiá. La diversidad de especies (índice de Shannon-Wiener) y la equitatividad (J) de Hemerobiidae fueron similares para las áreas Cerrado sensu stricto y bosque de galería (H' = 0,47 - 0,49 y J = 0,78 - 0,69) y las diferencias observadas entre los sitios de colecta no fueron significativas.

This study aimed to identify the Hemerobiidae (Neuroptera) associated to Brazilian savannah and gallery forest, in Minas Gerais State, Brazil. The sampling was carried every two weeks at Brazilian savannah (Cerrado) in Divinópolis and at gallery forest in Pedra do Indaiá, both in Minas Gerais State, Brazil. Collecting was carried out between November 2003 and October 2004, with Malaise traps. A total of 181 specimens of five species of Hemerobiidae were collected. The species Nusalala tessellata, Megalomus impudicus, Hemerobius bolivari and Notiobiella sp. were collected in the two sites; the fifth species Sympherobius sp. was found only in Pedra do Indaiá. The species of diversity (index of Shannon-Wiener) and the equitability (J) of Hemerobiidae were similar in the areas of Brazilian savannah and gallery forest (H' = 0.47 - 0.49, respectively, and J = 0.78 - 0.69, respectively), and the differences observed between the two locations were not significant.
