Resumen Introducción: El monitoreo de bioindicadores es una herramienta importante para la conservación de áreas naturales protegidas. Diferentes grupos taxonómicos fueron estudiados como bioindicadores por presentar: facilidad de muestreo, respuestas variadas a la perturbación, riqueza asociada a otras especies, y taxonomía accesible. Objetivo: Comparar el potencial de cuatro taxones (Chilopoda, Scarabaeidae, Carabidae y Pompilidae) como bioindicadores ambientales, tomando en cuenta su facilidad de recolección, presencia de cambios en la composición de sus comunidades por perturbaciones, presencia de especies con preferencia por áreas perturbadas o conservadas; y diversidad correlacionada con la diversidad de los otros taxones. Métodos: El trabajo se realizó en la estación Biológica Manu Learning Centre en la Reserva de Biosfera del Manu, que comprende tres áreas en un gradiente de perturbación. Los ejemplares fueron recolectados con trampas pitfall, bandejas amarillas, trampas Malaise y monolitos, de mayo a diciembre del 2021. La facilidad de recolección se midió en términos de riqueza y abundancia; los cambios en la composición de sus comunidades mediante el análisis de similitud, escalamiento no métrico multidimensional, y partición de la diversidad beta; presencia de especies con preferencia con el análisis de correspondencia y el ajuste de bondad G de Williams; y finalmente la correlación de las diversidades con el índice de Spearman. Resultados: De los taxones estudiados, las de más fácil recolección fueron Scarabaeidae y Pompilidae. Existen cambios en la composición en todos los taxones, pero son importantes solo en Chilopoda y Scarabaeidae. En todos los taxones hay especies con preferencia por ambientes perturbados y no perturbados. Existe una alta correlación de las diversidades de Carabidae, Scarabaeidae y Chilopoda. Conclusiones: Todos los grupos responden de diferente forma a los gradientes de perturbación, Scarabaeidae y Chilopoda fueron los que tuvieron mejores características para ser considerados buenos bioindicadores.

Abstract Introduction: Bioindicator monitoring is a crucial conservation strategy within natural protected areas. Various taxonomic groups have been investigated as bioindicators due to their distinctive attributes, including ease of sampling, differential responses to disturbances, associations with species richness, and accessible taxonomy. Objective: To compare the potential of four taxa (Chilopoda, Scarabaeidae, Carabidae, and Pompilidae) as environmental bioindicators, considering their ease of collection, presence of changes in community composition due to disturbances, including species with preferences for disturbed or conserved areas; and to correlate their diversity with the diversity of other taxa. Methods: The study was conducted at the Manu Learning Centre Biological Station in the Manu Biosphere Reserve, which comprises three areas along a disturbance gradient. Specimens were collected using pitfall traps, yellow pan traps, Malaise traps, and monoliths from May to June in 2021. Ease of collection was measured in terms of richness and abundance; changes in the community composition were assessed using similarity analysis, non-metric multidimensional scaling, and beta diversity partitioning; presence of species with preferences was analyzed using correspondence analysis and G. Williams’ goodness-of-fir test; and diversity correlation using the Spearman index. Results: Among the taxa investigated, Scarabaeidae and Pompilidae were the easiest to collect. Changes in composition were observed in all taxa but were significant only in Chilopoda and Scarabaeidae. All taxa exhibited species with preferences for disturbed and undisturbed environments. There was a high correlation in diversities among Carabidae, Scarabaeidae, and Chilopoda. Conclusions: Our findings underscore the diverse responses exhibited by taxa along a disturbance gradient. Notably, Scarabaeidae and Chilopoda emerged as particularly robust bioindicators within the studied ecosystem.

Resumo O grupo dos insetos é um dos mais diversos do planeta e devido à degradação dos habitats, muitas dessas espécies estão sendo extintas, deixando uma carência de informações sobre a biologia básica de cada uma. Neste estudo, informações inéditas sobre a biologia de nidificação em ninhos-armadilha de Auplopus subaurarius são reveladas. Essa espécie trata-se de uma vespa solitária ectoparasitóide de aranhas, que nidifica em cavidades preexistentes. Utilizamos a metodologia de ninhos-armadilha para amostrar A. subaurarius em dois períodos amostrais diferentes (2017/2018 e 2020/2021), em três tipos de ambientes (floresta, campo e plantação de Eucalyptus). Em nosso estudo, a nidificação de A. subaurarius foi mais frequente nos meses mais quentes do ano (Novembro a Março), com maior abundância encontrada em áreas de floresta nativa e em plantações de Eucalyptus comparados à áreas de campo. Além disso, a espécie apresentou dois tempos de desenvolvimento, um curto (três meses) e um longo (até um ano). Além disso, as fêmeas foram maiores que os machos (peso e tamanho) e a razão sexual da espécie apresentou tendência à produção de fêmeas. Auplopus subaurarius apresentou sete espécies de inimigos naturais: Ceyxia longispina, Caenochrysis crotonis, Photochryptus sp.1, Photochryptus sp.2, Messatoporus sp., Ephuta icema e Sphaeropthalma sp. Ressaltamos a importância de ambientes arborizados para manutenção das populações de A. subaurarius e seus interagentes associados, tanto aranhas quanto inimigos naturais, uma vez que estes ambientes podem apresentar melhores condições de vida comparados à áreas campestres. Além disso, outras vespas solitárias que podem ter o mesmo estilo de vida de A. subaurarius, também podem ser afetadas positivamente pela conservação das florestas naturais e por um bom planejamento de plantações de silvicultura, as quais devem considerar os aspectos ecológicos das paisagens da Mata Atlântica. habitats extintas estudo ninhosarmadilha ninhos armadilha reveladas tratase trata se preexistentes A 2017/2018 20172018 2017 2018 (2017/201 2020/2021, 20202021 2020/2021 , 2020 2021 2020/2021) floresta, (floresta Eucalyptus. .

Abstract The insect group is one of the most diverse on the planet and due to habitat degradation, many of these species are becoming extinct, leaving a lack of information on the basic biology of each one. In this study, previously unseen information about nesting biology is revealed in Auplopus subaurarius trap nests. This is a solitary ectoparasitoid spider wasp that nests in preexisting cavities. We used a trap-nesting methodology to sample A. subaurarius in two different sampling periods (2017/2018 and 2020/2021) in three types of environment (forest, grassland and Eucalyptus plantation). In our study, the A. subaurarius nest building was more frequent during the hottest months of the year (November to March), with its highest abundance found within natural forest areas and in Eucalyptus plantation than in grassland areas. In addition, the species had two development times: a short one (three months) and a delayed one (up to one year). Moreover, females were larger than males (weight and size) and the species’ sex ratio had a tendency toward female production. Auplopus subaurarius presented seven natural enemy species: Ceyxia longispina, Caenochrysis crotonis, Photochryptus sp.1, Photochryptus sp.2, Messatoporus sp., Ephuta icema and Sphaeropthalma sp. We emphasize the importance of wooded environments to maintain the A. subaurarius populations and their associated interactors, both spiders and natural enemies, as these environments can provide better life conditions than grassland areas. Furthermore, other solitary wasps that may have the same lifestyle of A. subaurarius can also be improved by natural forest conservation and by good silviculture plantation planning, which should consider ecological aspects of Atlantic Forest landscapes. degradation extinct study cavities trapnesting A 2017/2018 20172018 2017 2018 (2017/201 2020/2021 20202021 2020 2021 forest, (forest plantation. . plantation) November March, March , March) addition times up year. year) Moreover weight size production longispina crotonis sp1 sp 1 sp.1 sp2 2 sp.2 interactors enemies Furthermore planning landscapes 2017/201 2017201 201 (2017/20 2020/202 2020202 202 2017/20 201720 20 (2017/2 2020/20 202020 2017/2 20172 (2017/ 2020/2 20202 2017/ (2017 2020/ (201 (20 (2 (

Abstract Background: The composition of the venom from solitary wasps is poorly known, although these animals are considered sources of bioactive substances. Until the present moment, there is only one proteomic characterization of the venom of wasps of the family Pompilidae and this is the first proteomic characterization for the genus Pepsis. Methods: To elucidate the components of Pepsis decorata venom, the present work sought to identify proteins using four different experimental conditions, namely: (A) crude venom; (B) reduced and alkylated venom; (C) trypsin-digested reduced and alkylated venom, and; (D) chymotrypsin-digested reduced and alkylated venom. Furthermore, three different mass spectrometers were used (Ion Trap-Time of Flight, Quadrupole-Time of Flight, and Linear Triple Quadruple). Results: Proteomics analysis revealed the existence of different enzymes related to the insect’s physiology in the venom composition. Besides toxins, angiotensin-converting enzyme (ACE), hyaluronidase, and Kunitz-type inhibitors were also identified. Conclusion: The data showed that the venom of Pepsis decorata is mostly composed of proteins involved in the metabolism of arthropods, as occurs in parasitic wasps, although some classical toxins were recorded, and among them, for the first time, ACE was found in the venom of solitary wasps. This integrative approach expanded the range of compounds identified in protein analyses, proving to be efficient in the proteomic characterization of little-known species. It is our understanding that the current work will provide a solid base for future studies dealing with other Hymenoptera venoms.

ABSTRACT Atopopompilus Arnold, 1937 is a small genus of Pompilini. Most species are distributed in the Afrotropical Region, but there are a few in the Oriental region. In this contribution, the taxonomy of Atopopompilus from China is addressed, to ascertain species diversity and distribution in the country. One new species, Atopopompilus robusticarinatus Yang & Ma, sp. nov., is described from Yunnan and Tibet. The new species is similar to Atopopompilus daedalus daedalus (Bingham, 1896), but can be distinguished by the facial carina, the posterior margin of the pronotum and the male SGP and genitalia. In addition, the geographic distribution of and a key to the world species of Atopopompilus are updated. This study increased the number of known species Atopopompilus, and expanded the known distribution of the genus to the Palearctic region.

Abstract Introduction: Ephuta Say is a widespread New World genus of mutillid wasp whose ecology is poorly understood. Objective: The objective of this study was to determine how Ephuta species abundance varies annually and seasonally driven by weather conditions and hosts. Methods: Ephuta specimens, located in the “old forest” at Barro Colorado Island, were examined from weekly samples (2001-2006) of ten Malaise traps. The monthly abundance of each Ephuta species was compared with monthly average humidity, solar radiation, temperature and rainfall. Results: Nine species and ten morphospecies were identified. Most specimens were collected from March to June. April was the month reported with the greatest abundance. Of the four abiotic variables measured, only average monthly temperature was correlated with Ephuta abundance. Months with the highest number of Ephuta specimens were correlated with suspected host abundance, as indicated by the monthly abundance of Pompilidae (Hymenoptera) captured during the year 2007. Conclusions: We concluded that Ephuta display strong seasonal variation in abundance, with the peaks occurring during the end of the dry season and beginning of the rainy season, which correlate broadly with temperature and the abundance of their pompilid hosts.

Resumen Introducción: Ephuta es un género de avispas mutílidas ampliamente distribuido en el Nuevo Mundo y cuya ecología es poco conocida. Objetivo: El objetivo de este trabajo fue determinar cómo varía la abundancia de especies de Ephuta anualmente y estacionalmente debido a las condiciones climáticas y sus hospederos. Métodos: Se examinaron especímenes de Ephuta tomados de muestras semanales (2001-2006) de diez trampas Malaise, ubicadas en el “bosque viejo” de Isla Barro Colorado. La abundancia mensual de cada especie de Ephuta se comparó con el promedio mensual de la humedad, la radiación solar, la temperatura y las precipitaciones. Resultados: Se identificaron nueve especies y diez morfoespecies. La mayoría de los especímenes fueron recolectados de marzo a junio. La mayor abundancia mensual promedio se dio en abril. De las cuatro variables abióticas medidas, solo la temperatura mensual promedio se correlacionó con la abundancia de Ephuta. Los meses con el mayor número de especímenes de Ephuta se correlacionan con la sospechosa abundancia del huésped, como lo indica la abundancia mensual de Pompilidae (Hymenoptera) capturada durante el 2007. Conclusiones: Ephuta muestra una fuerte variación estacional en la abundancia, con picos durante el final de la estación seca y el comienzo de la temporada de lluvias. Esta se correlaciona ampliamente con la temperatura y la abundancia de sus huéspedes pompílidos.

Resumen En el presente estudio se dan a conocer por primera vez, datos sobre la interacción entre ejemplares de avispas de la especie Epipompilus platensis Roig Alsina, 2017 (Hymenoptera, Pompilidae) y arañas de la especie Ariadna mollis (Holmberg 1876) (Araneae, Segestriidae), en las localidades de Punta Lara (partido de Ensenada) y José Hernández (partido de La Plata), ambas pertenecientes a la provincia de Buenos Aires. Se recolectaron varios ejemplares de A. mollis en el mes de abril del 2015, y se seleccionaron aquellos que presentaban un huevo o una pequeña larva adherida al dorso del abdomen. Se mantuvieron bajo observación en bioterio hasta completar el desarrollo al estado adulto de la avispa. Del total de las arañas colectadas, el 9.6% se encontró parasitado por avispas. De ese porcentaje, cuatro larvas de E. platensis llegaron al estado adulto (tres hembras y un macho). Los resultados obtenidos contribuyen al conocimiento de una nueva interacción entre avispas y arañas.

Abstract In the present study, data on the interaction between wasp specimens of the species Epipompilus platensis Roig Alsina, 2017 (Hymenoptera, Pompilidae) and spiders of the species Ariadna mollis (Holmberg 1876) (Araneae, Segestriidae) are presented for the first time. Present in the localities of Punta Lara (Partido de Ensenada) and José Hernández (Partido de La Plata), both belonging to the province of Buenos Aires. Several specimens of A. mollis were collected on april 2015, and those that presented an egg or a small larva attached to the back of the abdomen were selected. They were kept under observation in a bioterium until completing the development of the wasp's adult state. Of the total spiders collected, 9.6% were parasitized by wasps. Of that percentage, four larvae of E. platensis reached the adult stage (three females and one male). The results obtained contribute to the knowledge of a new interaction between wasps and spiders.

Resumen Las avispas depredadoras o cazadoras son importantes en los ecosistemas ya que regulan las poblaciones de otros insectos y arañas. En este trabajo se determinó la diversidad espacial y temporal de avispas depredadoras en los 2 tipos de vegetación principales del estado de Yucatán: selva baja caducifolia y selva mediana subcaducifolia. El material revisado proviene de trampas Malaise colocadas en áreas de los tipos de vegetación, que estuvieron activas 1 año y de recolectas con red aérea. Se revisaron 877 individuos pertenecientes a 4 familias de avispas depredadoras (Crabronidae, Pompilidae, Sphecidae y Vespidae), se identificaron 68 especies, siendo Crabronidae la familia con mayor riqueza (26) y Pompilidae la de mayor abundancia (458 individuos). En la selva baja caducifolia se encontró mayor abundancia y riqueza de especies (86% y 91%, respectivamente) que en la selva mediana subcaducifolia (48% y 13%). No hubo diferencias en la riqueza de especies y la abundancia entre temporadas del año, pero la composición de especies tuvo baja similitud. Se encontraron 10 nuevos registros de especies para Yucatán. Se sugieren otros estudios de estas avispas en el neotrópico, en especial en México, y se indica la importancia de su biodiversidad en los ecosistemas estudiados para su conservación y posible uso.

Abstract Predatory wasps or hunters are important in ecosystems because they regulate the populations of other insects and spiders. In the state of Yucatán, these insects have been studied very little and in this work, their spatial and temporal diversity was determined in the 2 main vegetation types of Yucatán, low deciduous forest and the medium subcaducifolia forest. The material reviewed comes from Malaise traps placed in areas of vegetation types, which were active one year and from collections with aerial networks. We reviewed 877 individuals belonging to 4 families of predatory wasps (Crabronidae, Pompilidae, Sphecidae and Vespidae), 68 species were identified, being Crabronidae the richest family (26) and Pompilidae the most abundant (458 individuals). In the low deciduous forest, the highest abundance and species richness was found (86% and 91%, respectively) than in the medium subcaducifolia forest (48% and 13%). There were no differences in species richness and abundance between seasons of the year but the composition of species had low similarity. Ten new species records were found for Yucatán. Other studies of these wasps are suggested in the neotropics, especially in Mexico, and the importance of their biodiversity in the studied ecosystems is indicated for their conservation and possible use.

Abstract The Hymenoptera collection of the Museu de Zoologia da Universidade de São Paulo, Brazil (MZSP) houses one of the most important collections for the Brazilian and Neotropical wasp faunas. The present catalogue lists the type specimens of Pompiloidea, Thynnoidea and Vespoidea (Insecta, Hymenoptera) deposited in the MZSP. The collection includes a total of 422 type specimens (66 holotypes, 28 lectotypes, 278 paratypes, 45 paralectotypes, and five syntypes), being 91 Pompiloidea (40 Mutillidae type specimens of 10 genera and 25 species, 51 Pompilidae type specimens of 4 genera and 27 species), 191 Vespoidea (15 genera and 86 species of Vespidae), and 18 Thynnoidea (eight genera and 12 species of Thynnidae). All information written in labels was compiled and is presented along with additional data from the original descriptions, MZSP records and other sources. We provide Specimage links to high-resolution photographs of holotypes and lectotypes at the Hymenoptera image database of the Ohio State University.

ABSTRACT: 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 área. 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.

En este trabajo se presenta la información faunística de avispas depredadoras, reunida en un año de recolectas en 6 áreas naturales protegidas (ANP) del estado de Yucatán, México. Los resultados se compararon con la información publicada para el estado y se determinó la similitud en la composición de las especies entre las ANP. Se determinaron 1,145 ejemplares pertenecientes a 4 familias, los cuales se encuentran depositados en la Colección Entomológica Regional de la Universidad Autónoma de Yucatán. Se registraron 78 especies y morfoespecies; 26 especies son nuevos registros para Yucatán y la península de Yucatán. La familia Vespidae fue la mejor representada (68% de los ejemplares), seguida de Pompilidae (23%), Crabronidae (8%) y Sphecidae (1%). Las ANP con el mayor número de especies fueron Yalahau y Tabi (43 y 32 especies, respectivamente). La mayor similitud, en la composición de especies, se encontró entre las ANP Kabah y Tabi (57%). Los resultados indican que se requieren más estudios encaminados a conocer la fauna de avispas depredadoras en la región tropical de México.

This paper provides faunistic information of predatory wasps collected during one year of field work in 6 Natural Protected Areas (NPAs) from the state of Yucatán, Mexico. The results are compared with published information for the state and the similarity was determined in the species composition between NPAs. The study included 1,145 specimens belonging to 4 families, which are deposited in the Entomological Collection Regional Autonomous University of Yucatán. We recorded 78 species and morphospecies; 26 species are new records for Yucatán and the Yucatán Peninsula. Vespidae had the highest number of specimens (68%), followed by Pompilidae (23%), Crabronidae (8%) and Sphecidae (1%). NPAs with the highest number of species were Yalahau and Tabi (43 and 32 species, respectively). Highest similarity was found between NPAs Tabi and Kabah (57%). The results indicate that more studies are needed in order to know the predatory wasps' fauna of tropical areas in Mexico.

Neste trabalho realizamos um inventário da fauna de vespas predadoras (Hymenoptera, Vespoidea) do Parque Nacional da Serra da Bodoquena (PNSB), municípios de Bodoquena, Bonito, Jardim e Porto Murtinho, em 42 dias descontínuos de amostragens entre fevereiro de 2007 a dezembro de 2008. Sete expedições de campo foram realizadas em áreas de Floresta Estacional Decidual e Floresta Estacional Semidecidual. As técnicas empregadas foram: coletas ativas com rede entomológica, armadilha de Malaise, bandejas amarelas (armadilha de Möericke) e coleta manual. Trezentos e sessenta e um indivíduos de Vespoidea foram capturados, representados por 107 espécies, em 59 gêneros, distribuídos nas seguintes famílias: Vespidae, Pompilidae, Mutillidae, Tiphiidae e Scoliidae. Vespidae foi o grupo mais freqüente. Pompilidae foi bem representado por um amplo conjunto de métodos de coleta, entretanto a maioria dos gêneros foi amostrada por uma técnica exclusiva. Scoliidae foi representado apenas por três indivíduos. As espécies Polybia (gr. occidentalis) e Agelaia multipicta (Vespidae) foram as mais abundantes dentre todas as vespas aculeadas amostradas. Sessenta e uma espécies capturadas estão representadas por apenas um único indivíduo (singletons). Estes dados acrescentam novos registros de distribuição de espécies de vespas para a região Centro-Oeste do Brasil de interesse biogeográfico.

This work aims at performing the inventory of predator wasps' fauna (Hymenoptera, Vespoidea) from Serra da Bodoquena National Park, Brazil, municipalities of Bodoquena, Bonito, Jardim and Porto Murtinho; with a discontinuous period of 42 days of collecting, between February/2007 to December/2008. Seven expeditions were undertaken in the field in areas of deciduous and semi deciduous seasonal forest. The techniques employed in faunal inventory were: active collection with entomological net, Malaise traps, Möericke traps and hand collecting. Three-hundred sixty one specimens in Vespoidea group were captured, represented by 107 species in 59 genera, distributed in the following families: Vespidae, Pompilidae, Mutillidae, Tiphiidae and Scoliidae. Vespidae were the most frequently sampled group. Pompilidae presented a wider range of records in relation to collection methods; however most genera are sampled by an exclusive technique. Scoliidae was only represented by tree individuals. Polybia (gr. occidentalis) and Agelaia multipicta (Vespidae) were the most abundant between all the Aculeata wasps sampled. Sixty one species was sampled with only one individual (singletons). This data input new records of distribution of wasp's species to Central Western Brazil with biogeographical interest.

Temperate forests of south Chile and Argentina treasure high levels of diversity and endemicity. However, there are few studies that quantify diversity patterns of higher species richness taxa like insects in these ecosystems., one of the less studied groups in spite of their high diversity are insect parasitoids. In this study we analyzed richness and diversity patterns of one group of parasitoids with higher endemicity pompilids (Hymenoptera: Pompilidae). We sampled four evergreen coastal forest habitats using Malaïse traps in Valdivia province along 21 dates and we obtained a total of 9 pompilid species within 3 genera. Despite of the low number of species collected, all species collected are endemics of Central Chilean and Subantarctic Subregions.

Los bosque templados del sur de Chile y Argentina mantienen altos niveles de diversidad y endemicidad. A pesar de ello pocos son los estudios centrados en cuantificar los patrones de diversidad de los taxa de mayor riqueza específica como los insectos en estos ecosistemas. uno de los grupos menos estudiados a pesar de su alta diversidad es el de los insectos parasitoides. En este trabajo se analizan los patrones de riqueza y diversidad de uno de los grupos de parasitoides con mayor endemicidad, los pompílidos (Hymenoptera: Pompilidae). Se muestrearon utilizando trampas Malaïse, cuatro hábitats de bosque siempreverde costero en la provincia de Valdivia durante 21 fechas, obteniéndose 9 especies de pompílidos pertenecientes a 3 géneros. A pesar del bajo número de individuos, todas las especies colectadas son endémicas de las Subrregiones Chilena Central y Subantártica.
