| Abstract Background: Wasp venoms constitute a molecular reservoir of new pharmacological substances such as peptides and proteins, biological property holders, many of which are yet to be identified. Exploring these sources may lead to the discovery of molecules hitherto unknown. This study describes, for the first time in hymenopteran venoms, the identification of an enzymatically inactive phospholipase A2 (PLA2) from the venom of the social wasp Polybia occidentalis. Methods: P. occidentalis venom was fractioned by molecular exclusion and reverse phase chromatography. For the biochemical characterization of the protein, 1D and 2D SDS-PAGE were performed, along with phospholipase activity assays on synthetic substrates, MALDI-TOF mass spectrometry and... |

| The wasps of the "Proctotrupoidea complex" (Ceraphronoidea, Proctotrupoidea y Platygasteroidea) are a very large and diverse group of parasitic Hymenoptera. It is a relatively old group, with fossils from the Jurassic period. All of them are parasitoids or hiperparasitoids of other arthropods, attacking most groups of terrestrial insects as well as centipeds and spiders. The present study summarizes the knowledge of this complex in Brazil. A total of 221 species are listed; they are distributed in the families Ceraphronidae (1), Megaspilidae (1), Diapriidae (84), Monomachidae (9), Pelecinidae (2), Proctotrupidae (12), Platygastridae (20), Scelionidae (92). Taxonomy, fossil records, distribution and hosts are reviewed. |

| The salivary system of the Hymenoptera consists of the mandible, hypopharynx and thoracic salivary glands. It is very important because it is related to various aspects of the life of the insects, such as pheromone production, feeding the young, food digestion and nest building. Adult Polistes versicolor (Olivier) individuals were dissected, the thoracic salivary glands removed and processed for scanning electronic microscopy and histological examination. The P. versicolor thoracic salivary gland presents alveolar secretory units, consists of pseudoacines and does not have a reservoir. Four types of cells are present in the gland. The T1 and T2 cells make up the pseudoacines and differ mainly by the many secretory vessels in T2. There is a cluster of T3... |

| 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... |

| ABSTRACT A taxonomic revision of the genus Scolia Fabricius, 1775 (Hymenoptera: Scoliidae) from Central America is presented. Two species of Scolia are present in Central America: S. (Discolia) guttata Burmeister, 1853 and S. (Hesperoscolia) rufiventris Fabricius, 1804, the latter representing the first record for Costa Rica, Panama and Colombia. The male of S. rufiventris is described and illustrated for the first time. Seasonal flight activity for S. guttata from two years of continuous Malaise trapping in Barro Colorado Island, Panama, is described. |
