Venoms represent a huge and essentially unexplored reservoir of bioactive components that may cure diseases that do not respond to currently available therapies. This review select advances reported in the literature from 2000 to the present about the new scenario of Hymenoptera venom composition. On account of new technologies in the proteomic approach, which presents high resolution and sensitivity, the combination of developments in new instruments, fragmentation methods, strategic analysis, and mass spectrometry have become indispensable tools for interrogation of protein expression, molecule interaction, and post- translational modifications. Thus, the biochemical characterization of Hymenoptera venom has become a major subject of research in the area... |

Sol i 2 is a potent allergen in Solenopsis invicta venom, and most humans exhibit reactivity to it. The Sol gem 2 allergen found in the venom of the Thai tropical fire ant Solenopsis geminata was analysed in the present study. The protein was present in higher amounts than other proteins, as determined by SDS-PAGE, and presumably has allergenic properties similar to those of Sol i 2. Sol gem 2 molecular weight is 28 and 15 kDa, respectively, under non-reducing and reducing conditions, indicating that its native form is a dimer. LC-MS/MS analysis confirmed its similarity to Sol i 2. The mono/dimeric form of Sol gem 2 was determined to be relevant by proteomic approach and immunoblotting. An anti-Sol gem 2 antibody was produced in mice, with a titer greater... |

Hymenoptera venoms are complex mixtures containing simple organic molecules, proteins, peptides, and other bioactive elements. Several of these components have been isolated and characterized, and their primary structures determined by biochemical techniques. These compounds are responsible for many toxic or allergic reactions in different organisms, such as local pain, inflammation, itching, irritation, and moderate or severe allergic reactions. The most extensively characterized Hymenoptera venoms are bee venoms, mainly from the Apis genus and also from social wasps and ant species. However, there is little information about other Hymenoptera groups. The Apis venom presents high molecular weight molecules - enzymes with a molecular weight higher than... |

Achterberg, C. van. |
The genera of the subfamilies Betylobraconinae, Hormiinae, Lysiterminae, Pambolinae-Chremylini, and Doryctinae-Ypsistocerini are revised. A key is given to the genera of groups belonging to the cyclostome grade including species with shortened and/or (partly) widened fore tarsus. Sixteen new genera and 62 new species are described and illustrated. The new genera concern: Mannokeraia gen. nov. (type species: M. apterus spec. nov. from Australia), Masona gen. nov. (type species: M. prognatha spec. nov. from U.S.A.), Anachyra gen. nov. (type species: A. setosipes spec. nov. from Australia), Pseudochremylus gen. nov. (type species: P. angulifer spec. nov. from Australia), Chremyloides gen. nov. (type species: C. cardaleae spec. nov. from Australia), Apoavga... |
