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.
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.
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.
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.
Molecular phylogeny of the insect order Hymenoptera: apocritan relationships.
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.
Simultaneous analysis of 16S, 28S, COI and morphology in the Hymenoptera: Apocrita – evolutionary transitions among parasitic wasps☆
The recovery of the ectoparasitic-containing proctotrupomorphs (Chalcidoidea and, in some analyses, Ceraphronoidea) as apical lineages argues that these biologies are reversals.
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.
The function of spider egg sacs in relation to parasitoids and predators, with special reference to the Australian fauna

Information presented supports the hypothesis that egg sacs are an effective barrier against scavenging predators (generalists), while coevolution between spiders and their specialized (highly adapted) parasitoids and predators is responsible for the specificity displayed by the latter two groups and the structural diversity evident of Egg sacs.
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.
Systematics of the world genera of Cardiochilinae (Hymenoptera : Braconidae)
The genera of Cardiochilinae are revised on the basis of a phylogeneticanalysis of qualitative and morphometric characters and 169 of the182 described species are placed in the new generic classification.
