The mitochondrial (mt) genome is, to date, the most extensively studied genomic system in insects, outnumbering nuclear genomes tenfold and representing all orders versus very few. Phylogenomic analysis methods have been tested extensively, identifying compositional bias and rate variation, both within and between lineages, as the principal issues confronting accurate analyses. Major studies at both inter- and intraordinal levels have contributed to our understanding of phylogenetic relationships within many groups. Genome rearrangements are an additional data type for defining relationships, with rearrangement synapomorphies identified across multiple orders and at many different taxonomic levels. Hymenoptera and Psocodea have greatly elevated rates of rearrangement offering both opportunities and pitfalls for identifying rearrangement synapomorphies in each group. Finally, insects are model systems for studying aberrant mt genomes, including truncated tRNAs and multichromosomal genomes. Greater integration of nuclear and mt genomic studies is necessary to further our understanding of insect genomic evolution.

- Long‐range PCR allows sequencing of mitochondrial genomes from environmental DNA (2017, background): “…in a single PCR has inherent time and cost advantages over amplification of multiple fragments, reduces the potential complications of nuclear- encoded mitochondrial pseudogenes (NUMTs) and avoids the rearrangement of targeted priming sites in mitogenomes with altered gene order (Cameron, 2014).”
- Mitochondrial DNA as a Molecular Marker in Insect Ecology: Current Status and Future Prospects (2021, background): “It contains 37 genes including 13 mitochondrial proteincoding genes (MPCGs), two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and a noncoding region (referred to as the control region, CR) which may control its replication and transcription (Boore 1999, Cameron 2014) (Table 2).”
- How to sequence and annotate insect mitochondrial genomes for systematic and comparative genomics research (2014, background): “1), the majority of insect species share this arrangement (see Cameron, 2014, for a full discussion of genome rearrangements found in insects).”
