2. 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

3. Heterologous expression and mutagenesis of recombinant Vespa affinis hyaluronidase protein (rVesA2)
Abstract Background: Crude venom of the banded tiger waspVespa affinis contains a variety of enzymes including hyaluronidases, commonly known as spreading factors. Methods: The cDNA cloning, sequence analysis and structural modelling of V. affinis venom hyaluronidase (VesA2) were herein described. Moreover, heterologous expression and mutagenesis of rVesA2

4. 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

5. 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

6. Foraging behavior of two egg parasitoids exploiting chemical cues from the stink bug Piezodorus guildinii (Hemiptera: Pentatomidae)
Abstract: Several parasitoids attacking the same host may lead to competition. Adult parasitoids’ abilities to find, parasitize and defend hosts determine resource’s retention potential. In soybean, two egg parasitoid species, Telenomus podisi and Trissolcus urichi (Hymenoptera: Platygastridae), compete on the egg masses of Piezodorus guildinii (Hemipter

7. First record of the parasitoid wasp Lymeon sp. (Ichneumonidae: Cryptinae) associated with spider eggs-sac of Araneus vincibilis (Araneae: Araneidae) in Northeastern Brazil
Resumo Lymeon Förster, 1869 é um grande gênero de Cryptinae (Ichneumonidae) com distribuição predominantemente neotropical, onde fêmeas atacam pequenos casulos de vários grupos de insetos e ovissacos de aranha. No presente estudo, relatamos o primeiro registro da interação entre a vespa parasitoide Lymeon sp. (Ichneumonidae), com o ovissaco da aranh

8. Cotesia invirae, sp. nov., from South Brazil: a new gregarious microgastrine wasp (Hymenoptera: Braconidae) reared from Opsiphanes invirae (Nymphalidae) feeding on palms
Abstract A new species of microgastrine wasp, Cotesia invirae Salgado-Neto & Whitfield, sp. nov., is described from southern Brazil in Santa Maria, Rio Grande do Sul. This species is a koinobiont gregarious larval endoparasitoid and spins a common mass of cocoons underneath the host caterpillars of Opsiphanes invirae (Huebner, 1818) (Lepidoptera: Nymphalidae

9. Ant fauna associated with Microgramma squamulosa (Kaulf.) de la Sota (Polypodiaceae) fern galls
Abstract Galls are neoformed plant structures created by cell hyperplasia and hypertrophy induced by a number of organisms, especially insects. After adult insects hatch, senescent galls may remain on the host plant and be occupied by a succession of fauna, the most important and dominant being ants. This study aimed at characterizing the ant fauna successor

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. 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

12. 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
