Abstract

The mitochondrial (mt) genome of Eumeta variegata Snellen (Psychidae) has been sequenced and annotated. The mt genome has a total length of 15,793 bp, consisting of 13 protein-coding genes, 22 tRNA, two rRNA genes, and an AT-rich control region (GenBank accession no. MN242985). The nucleotide composition was extremely AT-rich, and the AT content is 81.57%. The gene order is consistent with other sequenced mt genome of moths and butterflies from Ditrysia. The sequence similarity of E. variegate mt genomes between the specimen of China and South Korea is 98.38%, whereas the similarity between the specimen of China and Japan is 90.61%. The sequence of PCGs and rRNAs among different specimens are similar, and many differences are detected at the region of A + T-rich region and the tRNA block ‘ARNS ₁EF’.

Towards a mitogenomic phylogeny of Lepidoptera.

Martijn Timmermans, David Lees, Thomas J Simonsen (2014)

The backbone phylogeny of Lepidoptera remains unresolved, despite strenuous recent morphological and molecular efforts. Molecular studies have focused on nuclear protein coding genes, sometimes adding a single mitochondrial gene. Recent advances in sequencing technology have, however, made acquisition of entire mitochondrial genomes both practical and economically viable. Prior phylogenetic studies utilised just eight of 43 currently recognised lepidopteran superfamilies. Here, we add 23 full and six partial mitochondrial genomes (comprising 22 superfamilies of which 16 are newly represented) to those publically available for a total of 24 superfamilies and ask whether such a sample can resolve deeper lepidopteran phylogeny. Using recoded datasets we obtain topologies that are highly congruent with prior nuclear and/or morphological studies. Our study shows support for an expanded Obtectomera including Gelechioidea, Thyridoidea, plume moths (Alucitoidea and Pterophoroidea; possibly along with Epermenioidea), Papilionoidea, Pyraloidea, Mimallonoidea and Macroheterocera. Regarding other controversially positioned higher taxa, Doidae is supported within the new concept of Drepanoidea and Mimallonidae sister to (or part of) Macroheterocera, while among Nymphalidae butterflies, Danainae and not Libytheinae are sister to the remainder of the family. At the deepest level, we suggest that a tRNA rearrangement occurred at a node between Adeloidea and Ditrysia+Palaephatidae+Tischeriidae.

Evolution of the mitochondrial cytochrome oxidase II gene among 10 orders of insects.

Hong. Liu, Andrew T. Beckenbach (1992)

We examine the complete nucleotide sequences of the mitochondrial cytochrome oxidase II gene of 13 species of insects, representing 10 orders. The genes range from 673 to 690 bp in length, encoding 226 to 229 amino acids. Several insertion or deletion events, each involving one or two codons, can be observed. The 3' end of the gene is extremely variable in both length and sequence, making alignment of the ends unreliable. Using the first 639 nucleotide positions, for which unambiguous alignments could be obtained, we examine the neighbor-joining trees based on nucleotide divergences and based on conserved subsets of that data, including transversion and amino acid and second codon position divergences. Each of these subsets produces different trees, none of which can be easily reconciled with trees constructed using morphology and the fossil record. Bootstrap analysis using second codon positions strongly supports affinities between the order Blatteria (cockroaches) and the order Isoptera (termites) and between a wasp and the published honeybee sequence (Order Hymenoptera). The divergence of insect orders is very ancient and may have occurred too rapidly for easy resolution using mitochondrial protein sequences. Unambiguous resolution of insect orders will probably require analysis of many additional taxa, using the COII gene and other conserved sequences.

Detecting Deep Divergence in Seventeen Populations of Tea Geometrid (Ectropis obliqua Prout) in China by COI mtDNA and Cross-Breeding

Gui-Hua Zhang, Zhi-Jun Yuan, Chuan-Xi Zhang … (2014)

The tea geometrid (Ectropis obliqua Prout, Lepidoptera: Geometridae) is a dominant chewing insect endemic in most tea-growing areas in China. Recently some E. obliqua populations have been found to be resistant to the nucleopolyhedrovirus (EoNPV), a host-specific virus that has so far been found only in E. obliqua. Although the resistant populations are morphologically indistinguishable from susceptible populations, we conducted a nationwide collection and examined the genetic divergence in the COI region of the mtDNA in E. obliqua. Phylogenetic analyses of mtDNA in 17 populations revealed two divergent clades with genetic distance greater than 3.7% between clades and less than 0.7% within clades. Therefore, we suggest that E. obliqua falls into two distinct groups. Further inheritance analyses using reciprocal single-pair mating showed an abnormal F1 generation with an unbalanced sex ratio and the inability to produce fertile eggs (or any eggs) through F1 self-crossing. These data revealed a potential cryptic species complex with deep divergence and reproductive isolation within E. obliqua. Uneven distribution of the groups suggests a possible geographic effect on the divergence. Future investigations will be conducted to examine whether EoNPV selection or other factors prompted the evolution of resistance.
