Characterization of 67 mitochondrial tRNA gene rearrangements in the Hymenoptera suggests that mitochondrial tRNA gene position is selectively neutral.
It is found that the vast majority of mitochondrial gene rearrangements are independently derived, and that there are an enormous number of alternative mitochondrial genome organizations possible and that mitochondrial genome organization is, for the most part, selectively neutral. Expand
Evolutionary dynamics of a mitochondrial rearrangement "hot spot" in the Hymenoptera.
Findings are consistent with the view that during the evolution of the Hymenoptera, rearrangements increased at the same time that the rate of point mutations and compositional bias also increased, and may direct investigations into mitochondrial genome plasticity in other invertebrate lineages.

Phylogeny of the parasitic microgastroid subfamilies (Hymenoptera: Braconidae) based on sequence data from seven genes, with an improved time estimate of the origin of the lineage.
This work represents a more extensive attempt to resolve the microgastroid relationships, using seven genes (16S rRNA, cytochrome oxidase I (CO1), 28S r RNA, arginine kinase (ArgK), long wavelength rhodopsin (Ops), elongation factor 1 alpha (EF1a) and wingless) and a greater taxonomic representation.

Phylogenetic relationships among the major groups of hymenopteran insects were investigated by using comparative sequence information from the mitochondrial 16S rRNA gene, and strong evidence was found for the monophyly of the Ichneumonomorpha and the sister-group relationship between the Aculeata (Vespomorpha) and the Ich pneumorpha.

Systematics, evolution, and biology of scelionid and platygastrid wasps.
The Trissolcus basalis-Nezara viridula parasitoid-host association has become a favored model system in ecological, behavioral, and physiological research on insects. Expand
Molecular phylogeny of the apocritan wasps: the Proctotrupomorpha and Evaniomorpha
Phylogenetic relationships among the apocritan wasps were investigated using comparative sequence data from the mitochondrial 16S rRNA gene, and relationships that were not sensitive to the alignment procedure are discussed. Expand
Synopsis of Australasian Microgastrinae (Hymenoptera : Braconidae), with a key to genera and description of new taxa
The genera of microgastrine braconid wasps present in the Australasian region are reviewed, and the generic placement of all species recorded from the region is reassessed since a recent generic reclassification of the subfamily left most of theAustralasian species incorrectly placed. Expand
Comparison of preservation techniques for DNA extraction from hymenopterous insects
Two species of parasitic wasp were killed and preserved by various methods used for Hymenoptera and in mass‐collecting devices, and genomic DNA was subsequently extracted and a 524 bp fragment of the mitochondrial 16s ribosomal RNA gene amplified by PCR. Expand
Frequent Mitochondrial Gene Rearrangements at the Hymenopteran nad3–nad5 Junction
The organization of mitochondrial genes from a diverse range of hymenopterans was characterized, and local inversions were relatively common, i.e., rearrangements characterized by the movement of genes from one mitochondrial strand to the other, opposite or close to their ancestral position. Expand
