The 'Symphyta' is a paraphyletic assemblage at the base of the order Hymenoptera, comprising 14 families and about 8,750 species. All have phytophagous larvae, except for the Orussidae, which are parasitoids. This study presents and evaluates the results of DNA barcoding of approximately 5,360 specimens of 'Symphyta', mainly adults, and 4,362 sequences covering 1,037 species were deemed of suitable quality for inclusion in the analysis. All extant families are represented, except for the Anaxyelidae. The majority of species and specimens are from Europe, but approximately 38% of the species and 13% of the specimens are of non-European origin...

BACKGROUND: The sawfly family Pergidae is best represented in South America, and it is the third largest family in the suborder Symphyta. Tequus is a Neotropical genus that has been reported in association with host plants of the genus Solanum (Solanaceae), with little information about the life history of its members. Tequus schrottkyi (Konow, 1906) was described from Paraguay, without any information about its biology and host plant. NEW INFORMATION: We report the first record of T...

The Symphyta is traditionally accepted as a paraphyletic group located in a basal position of the order Hymenoptera. Herein, we conducted a comparative analysis of the mitochondrial genomes in the Symphyta by describing two newly sequenced ones, from Trichiosoma anthracinum, representing the first mitochondrial genome in family Cimbicidae, and Asiemphytus rufocephalus, from family Tenthredinidae. The sequenced lengths of these two mitochondrial genomes were 15,392 and 14,864 bp, respectively. Within the sequenced region, trnC and trnY were rearranged to the upstream of trnI-nad2 in T...

Chemical communication is the oldest form of communication, spreading across all forms of life. In insects, cuticular hydrocarbons (CHC) function as chemical cues for the recognition of mates, species, and nest-mates in social insects. Although much is known about the function of individual hydrocarbons and their biosynthesis, a phylogenetic overview is lacking. Here, we review the CHC profiles of 241 species of Hymenoptera, one of the largest and most important insect orders, which includes the Symphyta (sawflies), the polyphyletic Parasitica (parasitoid wasps), and the Aculeata (wasps, bees, and ants)...

Landscape structure as well as local vegetation influence biodiversity in agroecosystems. A study was performed to evaluate the effect of floristic diversity, vegetation patterns, and landscape structural connectivity on butterflies (Lepidoptera: Papilionoidea and Hesperiidae), carabids (Coleoptera: Carabidae), syrphids (Diptera: Syrphidae), and sawflies (Hymenoptera: Symphyta). Vegetation analysis and insect samplings were carried out in nine sites within an intensively farmed landscape in northern Italy. Plant species richness and the percentage of tree, shrub, and herb cover were determined by means of the phytosociological method of Braun-Blanquet...

The mitochondrial genome sequence of Tenthredo tienmushana (Takeuchi, 1940) (Hymenoptera: Tenthredinidae) (GenBank accession KR703581) was reported. The length of the sequenced region of this mitochondrial genome is 14,943 bp, with 13 protein-coding, two rRNA, 19 tRNA (the trnI, trnQ, and trnM were failed to sequence) genes and a partial A + T-rich region. As in most other sequenced mitochondrial genomes of the suborder "Symphyta", there is no gene rearrangement in the sequenced region compared with the pupative ancestral gene arrangement of insects...

Two species of the Empria candidata species complex, E. candidata (Fallén, 1808) and E. magnicornis (Eversmann, 1864) spec. rev., comb. nov., are revised and redescribed. The males and larvae of both species are identified, described and the males are associated with the corresponding females. The species are redefined based on the revision of the available types. Lectotypes are designated for Tenthredo (Allantus) repanda Klug, 1816 and Tenthredo (Macrophya) magnicornis Eversmann, 1864.

BACKGROUND: Nygmata are prominent glandular structures on the wings of insects. They have been documented in some extant insects, including several families of Neuroptera and Mecoptera, the majority of Trichoptera, and a few of the hymenopteran Symphyta. However, because nygmata are rarely preserved in compression fossils, their early development and evolution are still enigmatic. For example, the only documented nygmata in the Hymenoptera are on the forewings of the Triassic xyelids Asioxyela paurura and Madygenius primitives...

Ventral glands are common in nematine larvae (Hymenoptera: Symphyta), but they show various degrees of development and are functional for defense only in some species. In those species, volatile irritants are produced which are effective against ants. Alternative or complementary mechanisms against ants are the pubescence ofTrichiocampus spp., the foam pillars constructed byStauronema compressicornis, various movements of the abdomen, which occur independently of the glandular secretion in several species, immobility of the flat larvae ofNematinus luteus, and burrowing within plant tissues in gallicolous larvae or miners...

Externally feeding phytophagous insect larvae (i.e., caterpillars, here, larval Lepidoptera and sawflies, Hymenoptera: Symphyta) are important canopy herbivores and prey resources in temperate deciduous forests. However, composition of forest trees has changed dramatically in the eastern United States since 1900. In particular, browsing by high densities of white-tailed deer (Odocoileus virginianus) has resulted in forests dominated by browse-tolerant species, such as black cherry (Prunus serotina), and greatly reduced relative abundance of other tree species, notably pin cherry (Prunus pensylvanica) and birches (Betula spp...

In Digelasinus diversipes, spermatozoa are maintained in bundles, with 74 spermatozoa on average, in the seminal vesicle. These spermatozoa are very short (20 μm) and consist of a head and flagellum. The head includes an acrosome (perforatorium covered by the acrosomal vesicle) and a nucleus. A regular electron-lucent region separates the acrosomal vesicle from the perforatorium, which is inserted parallel to the anterior ending of the nucleus. The small flagellum is composed of two symmetrical mitochondrial derivatives, a centriolar adjunct, an axoneme (9 + 9 + 2), and two accessory bodies...

BACKGROUND: Enormous molecular sequence data have been accumulated over the past several years and are still exponentially growing with the use of faster and cheaper sequencing techniques. There is high and widespread interest in using these data for phylogenetic analyses. However, the amount of data that one can retrieve from public sequence repositories is virtually impossible to tame without dedicated software that automates processes. Here we present a novel bioinformatics pipeline for downloading, formatting, filtering and analyzing public sequence data deposited in GenBank...

Each of the interior mandibular surfaces of Australian sawfly larvae in the subfamily Perginae is equipped with a soft, brush-like scopa mandibularis. These insects are associated with oil-rich Myrtaceae, including Eucalyptus, and the scopa is involved in separating leaf oils from nutritive plant matter. The oil is stored internally in a diverticulum and is emitted during defense reactions. However, this is known only from mature larvae and the mandibular structure has been investigated and partially illustrated in only one genus of pergines, Pergagrapta...

Larvae of nine species of sawflies (Symphyta) were fed with the foliage of three birch species, after which the larval hemolymph composition was studied by HPLC-DAD and HPLC-ESI-MS. The hemolymph of sawfly larvae contained high concentrations of flavonol oligoglycosides (tri-, tetra-, penta-, and hexaglycosides) that could not be found in the larval foliar diet. In addition, there were significant between-sawfly species differences in both flavonoid composition and concentration (from 0.6 to 12.3 mg/ml) of the hemolymph...

BACKGROUND: Animal mitochondrial genomes are potential models for molecular evolution and markers for phylogenetic and population studies. Previous research has shown interesting features in hymenopteran mitochondrial genomes. Here, we conducted a comparative study of mitochondrial genomes of the family Braconidae, one of the largest families of Hymenoptera, and assessed the utility of mitochondrial genomic data for phylogenetic inference at three different hierarchical levels, i.e., Braconidae, Hymenoptera, and Holometabola...

An in-depth proteomic study of previously unidentified two-dimensional polyacrylamide gel electrophoresis spots of honey bee (Apis mellifera, Hymenoptera) venom revealed a new protein with a C1q conserved domain (C1q-VP). BlastP searching revealed a strong identity with only two proteins from other insect species: the jewel wasp, Nasonia vitripennis (Hymenoptera), and the green pea aphid, Acyrthosiphon pisum (Hemiptera). In higher organisms, C1q is the first subcomponent of the classical complement pathway and constitutes a major link between innate and acquired immunity...
