The skeletomusculature of the head and mesosoma parasitoid wasp family Scelionidae is reviewed. Representatives 27 scelionid genera are examined together with 13 non-scelionid taxa for comparison. Terms employed other groups Hymenoptera reviewed, a consensus terminology proposed. External characters redescribed correlated corresponding apodemes, muscles putative exocrine gland openings; their phylogenetic importance discussed. 229 skeletal structures were termed defined, from which 84 newly...
The bacteriophage T7 RNA polymerase gene was integrated into the fowlpox virus genome under control of vaccinia early/late promoter, P7.5. recombinant virus, fpEFLT7pol, stably expressed in avian and mammalian cells, allowing transient expression transfected genes promoter. expressing offers an alternative to widely used vTF7-3, or recently developed modified Ankara (MVA) recombinant, a highly attenuated strain with restricted host-range. Recombinant viruses have advantage that as no...
We discuss the taxonomy of oak gallwasps (Hymenoptera: Cynipidae: Cynipini) whose lifecycle involves only Palaearctic oaks (Quercus subgen. Quercus) in section Cerris. Recent phylogenetic reconstructions support a deep split between such Cerris-associated species genera Aphelonyx, Dryocosmus, Plagiotrochus, Neuroterus, Pseudoneuroterus and associated with Quercus sensu stricto. reappraise generic limits genera, proposing new for establishing genus Cerroneuroterus, elevating Latuspina to...
Aims: Water activity (aw) and pH are probably the most important environmental parameters affecting activities of mycoparasitic Trichoderma strains. Therefore it is to collect information on effects these factors mycelial growth in vitro extracellular enzymes involved nutrient competition (e.g. β‐glucosidase, cellobiohydrolase β‐xylosidase) mycoparasitism N‐acetyl‐β‐glucosaminidase, trypsin‐like protease chymotrypsin‐like protease) strains with biocontrol potential. Methods Results:...
The recently identified Nimrod superfamily is characterized by the presence of a special type EGF repeat, NIM located right after typical CCXGY/W amino acid motif. On basis structural features, nimrod genes can be divided into three types. proteins encoded Draper-type have an EMI domain at N-terminal part and only one copy motif, followed variable number EGF-like repeats. products B-type C-type (including eater gene) different kinds domains, lack repeats but contain Draper (but not B-type)...
Cynipid gallwasps comprise 1364 species worldwide, predominantly in temperate regions of the Holarctic. The vast majority recorded are from Nearctic and Western Palaearctic, both which long-standing centers research on taxonomy biology this group. In contrast, Eastern Palaearctic Oriental Region faunas much less studied, but potentially extremely rich. Previously richness cynipid groups probably represents a significant underestimate. This is particularly marked for associated with oaks...
The construction of a full-length clone the avian coronavirus infectious bronchitis virus (IBV) defective RNA (D-RNA), CD-91 (9,080 nucleotides [Z. Penzes et al., Virology 203:286-293]), downstream bacteriophage T7 promoter is described. Electroporation in vitro T7-transcribed into IBV helper virus-infected primary chick kidney cells resulted production as replicating D-RNA subsequent passages. Three deletion mutants were constructed--CD-44, CD-58, and CD-61--in which 4,639, 3,236, 2,953...
Abstract. Several unanswered questions remain regarding the taxonomy and phylogeny of inquiline gallwasps (Cynipidae: Synergini), obligate inhabitants plant galls induced primarily by other Cynipini Diplolepidini). Here we use morphological molecular data to revise genus Synophrus , members which are notable for extensively modifying structure oak gallwasp hosts on oaks in section Cerris Quercus subgenus Western Palaearctic. Previous taxonomic treatments have recognized three Palaearctic...
Abstract Approximate Bayesian computation ( ABC ) is a powerful and widely used approach in inference of population history. However, the computational effort required to discriminate among alternative historical scenarios often limits set that compared those considered more likely priori. While justifiable, this will fail consider unexpected but well‐supported histories. We hierarchical tournament approach, which subsets are first round analyses winners second analysis, reconstruct history...
Abstract Oak gallwasps (Hymenoptera; Cynipidae, tribe Cynipini) are cyclically parthenogenetic insects that induce galls on specific plant hosts in the family Fagaceae. Understanding processes underlying evolution of oak associations requires knowledge phylogenetic relationships among gallwasp genera. Although three major lineages have been identified, status and several species‐poor but biologically significant genera remain unresolved. Two such Chilaspis Dryocosmus , whose western...
Eight new species of cynipid inquilines, Synergus abei Melika & Schwéger, S. belizinellus Schwéger Melika, changtitangi formosanus ishikarii kawakamii Tang khazani and symbioticus from the Eastern Palaearctic are described. Descriptions, diagnoses, biology, host associations for a key to all known given. All taxa supported by morphological molecular data. We discuss status previously described species, provide validation synonymization some species.
Male ornaments, such as plumage coloration, frequently serve signals. The signalling function of similar ornaments in females has, however, received much less attention despite the fact that conspicuousness their is often comparable to those males. In this study we tested a trait present both sexes Eurasian Tree Sparrow Passer montanus . black throat patch has been repeatedly found have signal closely related House domesticus , where only males bear ornamental trait. However, species...
Fourteen new species of oak gallwasps, Andricus istvani, assarehi, schoenroggei, csokai, chodjaii, megatruncicolus, coriariformis, libani, stellatus, Andricuspseudoaries, sadeghii, atkinsonae, pujadevillari and Dryocosmus caspiensis (Hymenoptera: Cynipidae: Cynipini) are described from Iran. Data on the diagnosis, distribution biology given.
The Nimrod gene superfamily is an important component of the innate immune response. majority its member genes are located in close proximity within Drosophila melanogaster genome and they lie a larger conserved cluster (“Nimrod cluster”), made up non‐related groups (families, superfamilies) genes. This has been part Arthropod genomes for about 300–350 million years. available data suggest that functional module insect
Abstract Previous phylogenetic studies of the tribe Synergini were focused on Palaearctic material, in which genus Synergus was recovered as monophyletic, despite evidence non-monophyly when global sampling is considered. A molecular phylogeny Synergini, including sequenced material from Nearctic and Neotropical realms, presented herein for first time. We assembled DNA data 120 specimens: 104 representing all genera belonging to except rare monospecific Agastoroxenia (ingroup), 16 five other...
