Statistic data and reports in specialized literature point to very frequent reactions to Hymenoptera venom; moreover the present stage of knowledge gained in the field of immunology allows us to establish the cases with local toxic reactions and those which involve a mechanism of allergical reaction. The Hymenoptera provided with a vulnerable sting apparatus consist of three families of social ...
Complex social behaviour in Hymenoptera has been hypothesized to evolve by co-opting reproductive pathways (the ovarian ground plan hypothesis, OGPH) and gene networks (the reproductive ground plan hypothesis, RGPH). In support of these hypotheses, in eusocial Hymenoptera where there is reproductive division of labour, the yolk precursor protein vitellogenin (Vg) influences the expression of wo...
Karyotypes of Entedon cionobius Thomson, 1878 and Entedon cioni Thomson, 1878 (Hymenoptera: Eulophidae) were studied using DNA-binding ligands with different base specificity (propidium iodide, chromomycin A3, methyl green and DAPI; all these ligands, except for the last one, were used for the first time in parasitic wasps), C-banding, fluorescence in situ hybridization (FISH) with a 45S rDNA p...
Fauna Europaea provides a public web-service with an index of scientific names (including important synonyms) of all living European land and freshwater animals, their geographical distribution at country level (up to the Urals, excluding the Caucasus region), and some additional information. The Fauna Europaea project covers about 230,000 taxonomic names, including 130,000 accepted species and...
Additions to the Iranian fauna of Ichneumonidae (Hymenoptera: Ichneumonoidea) with first records two genera and 13 species
The sting apparatus of aculeate Hymenoptera is derived from the ovipositor and their most prominent apomorphy. In contrast to frequently analysed sclerites apparatus, associated musculature has largely been neglected. this study, we use micro-computed tomography present a detailed description Ampulex compressa (Ampulicidae) Sceliphron destillatorium (Sphecidae). We found that 12 15 muscles corr...
A new species of Megischus Brullé from China, Megischus aplicatussp. n.,is described and illustrated. A key to the Chinese species of Megischus is added. The holotype is deposited in the Parasitic Hymenoptera Collection of Zhejiang University, Hangzhou.
Two new species of Encarsia Förster (Hymenoptera: Aphelinidae) are described from China, Encarsia floralis Wang, Huang & Polaszek, sp. nov. and Encarsia maculiformis Wang, Huang & Polaszek, sp. nov., and the male of Encarsia plana Viggiani & Ren (1987) is newly described.
Entedon magnificus (Girault & Dodd) (Hymenoptera: Eulophidae, Entedoninae) is recorded as a gregarious larval endoparasitoid of Gonipterus weevils (Coleoptera: Curculionidae), significant pests of Eucalyptus trees. Entedon magnificus is re-described and illustrated based on females and males from Australia and Tasmania.
Long-chain cuticular hydrocarbons (CHCs) are common components of the epicuticle of terrestrial arthropods. CHC serve as a protective barrier against environmental influences but also act as semiochemicals in animal communication. Regarding the latter aspect, species- or intra-functional group specific CHCs composition and variation are relatively well studied. However, comparative knowledge ab...
