Phylogenomics resolves the timing and pattern of insect evolution
The phylogeny of all major insect lineages reveals how and when insects diversified and provides a comprehensive reliable scaffold for future comparative analyses of evolutionary innovations among insects.
Evolutionary History of the Hymenoptera
Functional and Evolutionary Insights from the Genomes of Three Parasitoid Nasonia Species
Key findings include the identification of a functional DNA methylation tool kit; hymenopteran-specific genes including diverse venoms; lateral gene transfers among Pox viruses, Wolbachia, and Nasonia; and the rapid evolution of genes involved in nuclear-mitochondrial interactions that are implicated in speciation.

Beetles diversity appears to have resulted from multiple factors, including low extinction rates over a long evolutionary history, codiversification with angiosperms, and adaptive radiations of specialized herbivorous beetles following convergent horizontal transfers of microbial genes encoding PCWDEs.
Pancrustacean phylogeny in the light of new phylogenomic data: support for Remipedia as the possible sister group of Hexapoda.
This is the first time that a sister group relationship of Remipedia and Hexapoda has been inferred using a comprehensive phylogenomic data set that is based on EST data, and shows that selecting data subsets with increased overall signal can help to identify and prevent artifacts in phylogenetic analyses.
Orthograph: a versatile tool for mapping coding nucleotide sequences to clusters of orthologous genes
A new software pipeline, Orthograph, is presented that applies a best reciprocal hit approach to reference-based orthology prediction for coding nucleotide sequences such as RNAseq data and enables researchers to conveniently and reliably delineate orthologs and paralogs from transcriptomic and genomic sequence data.

Gene networks involved in generating key differences between the queen and worker castes show signatures of increased methylation and suggest that ants and bees may have independently co-opted the same gene regulatory mechanisms for reproductive division of labor.
Cytonuclear Genic Incompatibilities Cause Increased Mortality in Male F2 Hybrids of Nasonia giraulti and N. vitripennis
The observed MTRD in adult hybrids is ascribed to cytonuclear genic incompatibilities causing differential mortality during development since hybrid embryos did not show MTRS, which accounts for most of the intrinsic hybrid inviability in this cross.
Towards an 18S phylogeny of hexapods: accounting for group-specific character covariance in optimized mixed nucleotide/doublet models.
Behavioural and genetic analyses of Nasonia shed light on the evolution of sex pheromones
It is suggested that new pheromone compounds can persist in a sender’s population, without being selected against by the receiver and without the receiver having a pre-existing preference for the new phersomone phenotype, by initially remaining unperceived.
