1. Proteomic analysis of the venom of the social wasp Apoica pallens (Hymenoptera: Vespidae)
ABSTRACT Wasps are a diverse group of insects that possess a sting apparatus associated with a venom gland, which is used for predation and colony defense. The biochemistry of Hymenoptera venom has been evaluated in relation to allergy and immunology, and proteomics has been shown to be a powerful tool for the identification of compounds with pharmacological

2. Diversity of wasps (Hymenoptera: Aculeata: Vespidae) along an altitudinal gradient of Atlantic Forest in Itatiaia National Park, Brazil
ABSTRACT Surveying the diversity of stinging wasps (Hymenoptera: Aculeata) provides an important information base to assist in biodiversity conservation and the management of forest reserves, as wasps depend on and maintain the population balance of several other groups of insects. In accordance, this paper presents an altitudinal survey of wasps (Hymenopter

3. A phylogenetic investigation of the Neotropical genus Alphamenes van der Vecht, 1977 (Hymenoptera, Vespidae, Eumeninae)
ABSTRACT Advances in potter wasp systematics have been achieved recently, with classificatory changes resulting from analyses based upon large scale molecular datasets. For the Neotropics, recent hypotheses point to the occurrence of an exclusive clade recognized within the tribe Eumenini. In this group, several contributions regarding taxonomy and systemati

4. Taxonomic notes on social wasps of the groups of Mischocyttarus wagneri (Buysson 1908) and M. barbatus Richards 1945 (Hymenoptera, Vespidae, Polistinae)
ABSTRACT Taxonomic revisionary notes and identification keys are presented for two species-groups of wasps of the genus Mischocyttarus, subgenus Phi. Material of the M. wagneri and M. barbatus groups, including types, was examined in several collections, resulting in description of one new species for the first mentioned group (M. camanducaia sp. nov.), and

5. Type specimens of Pompiloidea, Thynnoidea and Vespoidea (Hymenoptera) deposited in the Museu de Zoologia da Universidade de São Paulo, Brazil
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 to

6. Levantamento de vespas sociais (Hymenoptera, Vespidae, Polistinae) em fragmentos de floresta Amazônica no Acre, Brasil
RESUMO O estado do Acre é parte da Amazônia Ocidental brasileira, uma área que abriga uma grande biodiversidade e alto grau de endemismos. Contudo, poucos estudos investigaram a diversidade de vespas sociais nesta região. Este trabalho apresenta os resultados de uma amostragem de vespas sociais (Hymenoptera,Vespidae, Polistinae) em três fragmentos de fl

7. Variation of cuticular chemical compounds in three species of Mischocyttarus (Hymenoptera: Vespidae) eusocial wasps
Abstract The social wasps have a remarkable system of organization in which chemical communication mediate different behavioral interactions. Among the compounds involved in this process, cuticular hydrocarbons are considered the main signals for nestmate recognition, caste differentiation, and fertility communication. The aims of this study were to describe

8. Inventário de vespas (Hymenoptera, Vespidae) no Mato Grosso do Sul, Brasil
RESUMO Este levantamento preliminar de vespas (Vespidae), realizado em pontos representativos dos biomas do Mato Grosso do Sul: Pantanal, Chaco, Cerrado e Mata Atlântica, abrange períodos de coletas entre 2006 a 2011, sendo a primeira tentativa de quantificar a fauna de Vespidae para o estado. A amostragem concentrou-se basicamente em áreas com bom estado

9. Nectarinella manauara, new species and record of the genus from Brazilian Amazonia (Hymenoptera, Vespidae, Polistinae)
ABSTRACT Nectarinella manaura sp. nov. is described, representing the first record of the genus from Brazilian Amazonia. Its description raises richness for Nectarinella from two to three species, and extends the range of characteristics for the genus, especially in terms of body size and color patterns. Discovery of the new species may shed new light into t

12. Note on predation of the brood of Mischocyttarus injucundus (de Saussure) by another social wasp in Caxiuanã, Pará, Brazil, with new records of species for the Ferreira Penna Research Station (Hymenoptera, Vespidae, Polistinae)
ABSTRACT Predation of the brood of Mischocyttarus injucundus by another polistine social wasp is reported from an Amazonian rainforest locality. This is the first report for the American tropics of naturally occurring predation by one social wasp on the brood of another. Three species are added to the list of the Ferreira Penna Research Station, raising know
