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. A new fossil species of the crabronid wasp genus Tracheliodes (Hymenoptera: Crabronidae) from Dominican amber
ABSTRACT The first fossil species of the wasp genus Tracheliodes from Dominican amber is described. Tracheliodes grimaldii sp. nov. is based on a single female specimen exhibiting a somewhat generalized morphology compared to the extant fauna. While the new species resembles the Neotropical species in a few characters, it does not possess the many specialize

3. A literature review of the pollination strategies and breeding systems in Oncidiinae orchids
ABSTRACT Oncidiinae is an exclusively Neotropical orchid subtribe with about 1600 described species and an impressive array of vegetative and floral morphological adaptations. We present the results of a literature survey on the pollination strategies and breeding systems of this orchid subtribe. The flowers are pollinated by a wide range of insects (mostly

4. Diversity of parasitoid wasps in conventional and organic guarana (Paullinia cupana var. sorbilis) cultivation areas in the Brazilian Amazon
RESUMO Pesquisamos vespas parasitoides (Hymenoptera) em duas plantações de guaraná na Amazônia central brasileira (uma convencional e outra manejada organicamente), bem como em florestas adjacentes e áreas de borda entre cultivo e floresta. Avaliamos as diferenças entre os sistemas de manejo na diversidade e abundância de parasitoides e a importância

5. Floral biology, pollination requirements and behavior of floral visitors in two species of pitaya
RESUMO O presente trabalho objetivou estudar a biologia floral, os requerimentos de polinização e o comportamento de visitantes florais em duas espécies de pitaia, Hylocereus undatus e H. polyrhizus no Nordeste do Brasil. O experimento foi conduzido com observações diurnas e noturnas e pelo uso de flores ensacadas ou acessíveis aos visitantes. Os resul

6. Two new species of Platydoryctes Barbalho and Penteado-Dias, 2000 (Hymenoptera: Braconidae: Doryctinae) from Brazil, with an identification key for species
Resumo Platydoryctes Barbalho and Penteado-Dias 2000 é um pequeno gênero Neotropical de vespas parasitoides (Hymenoptera: Braconidae: Doryctinae), com quatro espécies descritas até o presente. Duas novas espécies do gênero são descritas para o Brasil e uma chave para espécies é apresentada neste trabalho.Abstract Platydoryctes Barbalho and Penteado-

7. Social wasps (Vespidae: Polistinae) on carcasses of Rattus norvegicus (Mammalia: Muridae) in the Central Amazonia, Brazil: possible forensic implications
ABSTRACT We evaluated the occurrence of social wasps in the decomposition process in tropical rainforest in central Amazonia (Ducke Reserve, Manaus, Brazil), using cadavers of rats as attractants, exposed in suspended cages. Ten species, in three genera, of social wasps were collected only in the initial stages of decay (fresh and bloated). Five species were

8. 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

9. 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

10. 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

11. Are native bees and Apis mellifera equally efficient pollinators of the rupestrian grassland daisy Aspilia jolyana (Asteraceae)?
ABSTRACT Most angiosperms rely on animals for pollination, and insects, especially bees, are being the most frequent pollinators. Many native Neotropical plants are frequently visited by the invasive honeybee (Apis mellifera), but its role in the pollination of these plants has been little investigated. We assessed the contribution of various floral visitors

12. Nests of “caba-leão” wasps (Sceliphron sp., Sphecidae) used in traditional medicine by riverine communities of the Jaú and Unini Rivers, Amazon, Brazil: ethnopharmacological, chemical and mineralogical aspects
ABSTRACT This research contributes to the study of substances present in homemade remedies used by the riverine communities of the Amazon, which are the result of insect–mineral–vegetable oil-interaction. The results of the analyses show the main components (inorganic and organic components) of the “caba-leão” wasps nests (Sceliphron sp., Sphecidae)
