BackgroundAnimal 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… 

Multiple Lines of Evidence from Mitochondrial Genomes Resolve Phylogenetic Relationships of Parasitic Wasps in Braconidae

The strand-asymmetry of base composition in the mitochondrial genomes of braconids is reversed, providing evidence for monophyly of the Braconidae, and multiple uses of mitochondrial genomes for phylogenetic inference in Braconids are illustrated.

The mitochondrial genome of Binodoxys acalephae (Hymenoptera: Braconidae) with unique gene rearrangement and phylogenetic implications

Phylogenetic analysis showed that both Bayesian and maximum-likelihood methods recovered the monophyly of Aphidiinae and suggested that Aphidiinee formed sister clades with the remaining subfamilies and gene clusters tRNATrp-tRNACys-tRNATyr and CR-tRNAIle-t RNAMet were hotspots for gene rearrangement.

Massive gene rearrangements of mitochondrial genomes and implications for the phylogeny of Trichoptera (Insecta)

This study assembles new mitogenomes for 66 species by high‐throughput sequencing and offers new insights into the mechanisms and patterns of mitogenome rearrangements in Insecta at large and into the usefulness ofMitogenomic gene order as a phylogenetic marker within Trichoptera.

Next-Generation Sequencing of Two Mitochondrial Genomes from Family Pompilidae (Hymenoptera: Vespoidea) Reveal Novel Patterns of Gene Arrangement

The genomes presented in this study have enriched the knowledge base of molecular markers, which is valuable in respect to studies about the gene rearrangement mechanism, genomic evolutionary processes and phylogeny of Hymenoptera.

Rapid Evolution of the Mitochondrial Genome in Chalcidoid Wasps (Hymenoptera: Chalcidoidea) Driven by Parasitic Lifestyles

A comparison of all available hymenopteran mitochondrial genomes revealed that the Chalcidoids had dramatic mitochondrial gene rearrangments, involved not only the tRNAs, but also several protein-coding genes.

Accelerated Evolution of Mitochondrial but Not Nuclear Genomes of Hymenoptera: New Evidence from Crabronid Wasps

The results suggest that the ancestral parasitic lifestyle of Apocrita is unlikely to be the major cause for the elevated substitution rates observed in hymenopteran mitochondrial genomes.

Mitochondrial phylogenomics and mitogenome organization in the parasitoid wasp family Braconidae (Hymenoptera: Ichneumonoidea)

Both the mt genome DNA sequence data and gene organization contain valuable phylogenetic signal to elucidate the evolution within Braconidae at different taxonomic levels, and serve as a basis for further investigation of mt gene rearrangements at differentTaxonomic scales within the family.

The mitochondrial genomes of Panorpidae: sequence, structure and phylogenetic analysis

The analyses indicate that the genes nad2 and nad6 can be regarded as potential markers for population genetics and species delimitation in Panorpidae and Panorpa is reconfirmed a paraphyletic group.

The complete mitochondrial genome of Evania appendigaster (Hymenoptera: Evaniidae) has low A+T content and a long intergenic spacer between atp8 and atp6

The complete mitochondrial genome of Evania appendigaster is sequenced; with low A+T content, 77.8%, compared with other hymenopteran species, and four tRNA genes were rearranged, among which remote inversion is the dominant gene rearrangement event.

The complete mitochondrial genome of Diadegma semiclausum (hymenoptera: ichneumonidae) indicates extensive independent evolutionary events.

The results indicate that independent evolutionary events occurred extensively, such as gene rearrangement events, gene rearranged mechanisms, derivation of tRNA variable loops, and tandem repeat region evolutionary processes, all of which likely contribute to the diversified features of hymenopteran mitochondrial genomes.

Simultaneous Molecular and Morphological Analysis of Braconid Relationships (Insecta: Hymenoptera: Braconidae) Indicates Independent mt-tRNA Gene Inversions Within a Single Wasp Family

This phylogeny of the Braconidae is investigated with a much expanded data set compared with that of previous attempts, employing 16S and 28S rDNA gene fragments, together with a suite of morphological characters, from 74 ingroup taxa, and indicates parallel inversions of the mt-tRNAD gene.

Rapidly evolving mitochondrial genome and directional selection in mitochondrial genes in the parasitic wasp nasonia (hymenoptera: pteromalidae).

It is proposed that relatively high rates of amino acid substitution in some mitochondrial genes can be driven by a "Compensation-Draft Feedback"; increased fixation of mildly deleterious mutations results in selection for compensatory mutations, which lead to fixation of additional deleteriously mutations in nonrecombining mitochondrial genomes, thus accelerating the process of amino acids substitutions.

A Comparative Analysis of Mitochondrial Genomes in Coleoptera (Arthropoda: Insecta) and Genome Descriptions of Six New Beetles

Six new complete mitochondrial genome descriptions are presented, including a representative of each suborder, and the evolution of mtgenomes from a comparative framework using all available coleopteran mt Genomes is analyzed.

Mitochondrial genomes of Vanhornia eucnemidarum (Apocrita: Vanhorniidae) and Primeuchroeus spp. (Aculeata: Chrysididae): Evidence of rearranged mitochondrial genomes within the Apocrita (Insecta: Hymenoptera).

Most of the mitochondrial genomes of 2 apocritan taxa: Vanhornia eucnemidarum and Primeuchroeus spp.

The Mitochondrial Genome of the Screamer Louse Bothriometopus (Phthiraptera: Ischnocera): Effects of Extensive Gene Rearrangements on the Evolution of the Genome

Analyses of Bothriometopus demonstrate that louse mt genomes, in addition to being extensively rearranged, differ significantly from most insect species in nucleotide composition biases, tRNA evolution, protein-coding gene structures and putative signaling sites such as the control region.

The complete sequence of the mitochondrial genome of the honeybee ectoparasite mite Varroa destructor (Acari: Mesostigmata).

Complete mitochondrial genome sequences are now available for 28 Arthropoda (see references at), more than for any other invertebrate phylum, and major rearrangements in the gene order were found for two of these ticks: R. sanguineous and B. microplus.

Phylogenetic relationships among the microgastroid wasps (Hymenoptera: braconidae): combined analysis of 16S and 28S rDNA genes and morphological data.

Mapping of lifestyle traits onto this relatively well supported phylogeny indicated that solitary endoparasitism is ancestral for the microgastroids, with a single origin for egg-larval endoparsitism in the Cheloninae + Adeliinae.
