Ajene IJ, Heya H, Khamis FM. Evaluating the mitochondrial genomic diversity, global distribution and niche overlap of two invasive Phthorimaea species. Heliyon 2024; 10:e29010. [PMID: 38617910 PMCID: PMC11015427 DOI: 10.1016/j.heliyon.2024.e29010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Revised: 03/21/2024] [Accepted: 03/28/2024] [Indexed: 04/16/2024] Open
Abstract
This study sought to evaluate the genetic diversity of two invasive Phthorimaea species (Phthorimaea operculella Zeller and Phthorimaea absoluta Meyrick), and identify potential niche overlap of both species. The complete mitogenomes of P. operculella and P. absoluta were sequenced and compared. Furthermore, the diversity within the family Gelechiidae was assessed. Subsequently, two species distribution models (MaxEnt and BIOCLIM) were used to identify niche overlaps of both species globally. The complete mitogenomes of both species were similar in size and structure, with a pairwise identity of 92.3%. The models showed a niche overlap of both species and revealed areas of marginal to high suitability for both pests in countries where they have not been reported. Therefore, these results present a compelling case for a deeper genetic and ecological investigation of the Gelechiidae family for taxonomic harmonization, an early warning for surveillance, stricter phytosanitary considerations and preventive management against the spread of the pests.

Phylogenomics including the newly sequenced mitogenomes of two moths (Noctuoidea, Erebidae) reveals Ischyja manlia (incertae sedis) as a member of subfamily Erebinae. Genetica 2023; 151:105-118. [PMID: 36708484 DOI: 10.1007/s10709-023-00180-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2022] [Accepted: 01/17/2023] [Indexed: 01/29/2023]
Abstract
We sequenced the mitogenomes of two Erebid species, namely Ischyja manlia (Cramer, 1776) and Rusicada privata (Walker, 1865) to analyse the phylogenetic relationship and to establish the taxonomic position of incertae sedis members of the family Erebidae. The two circular genomes of I. manlia and R. privata were 15,879 bp and 15,563 bp long, respectively. The gene order was identical, containing 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes, and an A + T-rich region. The nucleotide compositions of the A + T-rich region of both mitogenomes were similar: 80.65% for R. privata, and 81.09% for I. manlia. The AT skew and GC skew were slightly positive in I. manlia and negative in R. privata. In I. manlia and R. privata, except for cox1 which started with CGA and TTG codons, all the other 12 PCGs started with ATN codon. The A + T-rich regions of I. manlia and R. privata were 433 and 476 bp long, respectively, and contained common characteristics of Noctuoidea moths. At present, Ischyja is treated as Erebinae incertae sedis. However, phylogenetic analysis conducted in the present study reveals that the genus Ischyja is most likely to be a member of the subfamily Erebinae.

Characterization of four mitochondrial genomes from superfamilies Noctuoidea and Hyblaeoidea with their phylogenetic implications. Sci Rep 2022; 12:18926. [PMID: 36344589 PMCID: PMC9640664 DOI: 10.1038/s41598-022-21502-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2021] [Accepted: 09/28/2022] [Indexed: 11/09/2022] Open
Abstract
In the present study, the newly sequenced mitogenomes of three Noctuoid and one Hyblaeoid (Insecta: Lepidoptera) species were annotated based on next-generation sequence data. The complete mitogenome lengths of Oraesia emarginata, Actinotia polyodon, Odontodes seranensis, and Hyblaea puera were 16,668 bp, 15,347 bp, 15,419 bp, and 15,350 bp, respectively. These mitogenomes were found to encode 37 typical mitochondrial genes (13 protein-coding, 22 transfer RNA, 2 ribosomal RNA) and a control region, similar to most Lepidoptera species. Maximum likelihood (ML) methods and Bayesian inference (BI) were used to reconstruct the phylogenetic relationships of the moths. This study showed the relationships of Noctuoid families as follows: (Notodontidae + (Erebidae + (Nolidae + (Euteliidae + Noctuidae)))). Furthermore, the species H. puera was separately clustered from the Noctuoidea member groups. Till now, the species from the superfamily Hyblaeoidea have not been discussed for their phylogenetic relationships. In this study, the complete mitochondrial genome of one species from the superfamily Hyblaeoidea was analysed.

Unfolding the mitochondrial genome structure of green semilooper (Chrysodeixis acuta Walker): An emerging pest of onion (Allium cepa L.). PLoS One 2022; 17:e0273635. [PMID: 36040876 PMCID: PMC9426943 DOI: 10.1371/journal.pone.0273635] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2022] [Accepted: 08/12/2022] [Indexed: 11/19/2022] Open
Abstract
Onion is the most important crop challenged by a diverse group of insect pests in the agricultural ecosystem. The green semilooper (Chrysodeixis acuta Walker), a widespread tomato and soybean pest, has lately been described as an emergent onion crop pest in India. C. acuta whole mitochondrial genome was sequenced in this work. The circular genome of C. acuta measured 15,743 base pairs (bp) in length. Thirteen protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes, and one control region were found in the 37 sequence elements. With an average 395 bp gene length, the maximum and minimum gene length observed was 1749 bp and 63 bp of nad5 and trnR, respectively. Nine of the thirteen PCGs have (ATN) as a stop codon, while the other four have a single (T) as a stop codon. Except for trnS1, all of the tRNAs were capable of producing a conventional clover leaf structure. Conserved ATAGA motif sequences and poly-T stretch were identified at the start of the control region. Six overlapping areas and 18 intergenic spacer regions were found, with sizes ranged from 1 to 20 bp and 1 to 111 bp correspondingly. Phylogenetically, C. acuta belongs to the Plusiinae subfamily of the Noctuidae superfamily, and is closely linked to Trichoplusia ni species from the same subfamily. In the present study, the emerging onion pest C. acuta has its complete mitochondrial genome sequenced for the first time.

Abstract
Ecological and life-history data on the Northern European macromoth (Lepidoptera: Macroheterocera) fauna is widely available and ideal for use in answering phylogeny-based research questions: for example, in comparative biology. However, phylogenetic information for such studies lags behind. Here, as a synthesis of all currently available phylogenetic information on the group, we produce a supertree of 114 Northern European macromoth genera (in four superfamilies, with Geometroidea considered separately), providing the most complete phylogenetic picture of this fauna available to date. In doing so, we assess those parts of the phylogeny that are well resolved and those that are uncertain. Furthermore, we identify those genera for which phylogenetic information is currently too poor to include in such a supertree, or entirely absent, as targets for future work. As an aid to studies involving these genera, we provide information on their likely positions within the macromoth tree. With phylogenies playing an ever more important role in the field, this supertree should be useful in informing future ecological and evolutionary studies.

Abstract
Fall armyworm, Spodoptera frugiperda J.E. Smith (Lepidoptera: Noctuidae), is an economically important pest worldwide and has recently been identified in Australia. Morphological identification of S. frugiperda at early larval stages can be difficult often requiring expert microscopy analysis. Rapid and accurate in-field diagnosis is vital for management decision support and there are no tools currently available for this purpose. In this study, a sensitive, specific, and in-field capable loop-mediated isothermal amplification (LAMP) assay was developed to detect S. frugiperda larvae. A primer set based on a highly conserved region of the S. frugiperda cytochrome oxidase subunit 1 (COX1) gene provided detection within 30 min from both total DNA and crude extractions. The crude extraction technique of crushing 10 mg of S. frugiperda material in 50 µl ddH2O and further diluting the homogenate in ddH2O is rapid, simple, and does not require heat blocks, centrifuges, or special buffers increasing its utility as a field-based technique. The primer set detected as little as 24 pg of S. frugiperda DNA and did not cross-react with any other of the lepidopteran species tested that are easily confused with S. frugiperda in Australia. Therefore, this assay could be used in-field to correctly identify the presence of S. frugiperda and thereby greatly assist with timely management decisions.

Abstract
BACKGROUND The fall armyworm, Spodoptera frugiperda is a native species of the Americas. First detected in western and central Africa in early 2016, it has become one of the most serious invasive lepidopteran pests in many African and Asian countries. S. frugiperda has spread very quickly; however, there are no molecular-based, simple and accurate diagnostic tools for identification of this species in the field. Methods to identify invasive S. frugiperda are urgently needed because farmers and agricultural managers have no prior experience with this pest. RESULTS Based on mitochondrial genome sequence alignment, a S. frugiperda-specific sequence region was identified in the transfer RNA-coding region between NADH dehydrogenase, ND3, and ND5. Using this unique region, species-diagnostic primers were designed and applied in a loop-mediated isothermal amplification (LAMP) assay and a conventional polymerase chain reaction to identify field-collected samples of S. frugiperda. The optimal incubation conditions for the LAMP assay were 61°C for 90 min with four LAMP primers; an additional loop primer increased the amplification efficiency. A response was obtained for a wide range of DNA concentrations in the LAMP assay and the minimum detectable DNA concentration was 10 pg. CONCLUSIONS We developed a new LAMP-based molecular diagnostic method that it is easy to use and accurate. The LAMP assay was used with a DNA-releasing technique for larval and adult samples, without a DNA extraction step, by incubating the tissue sample at 95°C for 5 min. This method can be applied in intensive field monitoring of S. frugiperda and its ecological studies. © 2021 Society of Chemical Industry.

Comparative mitochondrial genome analysis of Eudocima salaminia (Cramer, 1777) (Lepidoptera: Noctuoidea), novel gene rearrangement and phylogenetic relationship within the superfamily Noctuoidea. Mol Biol Rep 2021; 48:4449-4463.

Abstract
The species Eudocima salaminia (Cramer, 1777) commonly known as the fruit-piercing moth belongs to family Erebidae. Its distribution varies from India and across South-east Asia, pacific islands and parts of Australia. The insect is a devastating pest of citrus, longans and lychees. In the present study, complete mitochondrial genome of Eudocima salaminia was sequenced and analyzed using Illumina sequencer. The phylogenetic tree was reconstructed based on nucleotide sequences of 13 PCGs using Maximum likelihood method-General Reversible mitochondrial (mtREV) model. The mitogenome has 15,597 base pairs (bp) in length, comprising of 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes and A + T-rich region. All protein-coding genes (PCGs) initiate with canonical start codon ATN. The gene order (trnQ-trnI-trnM) of tRNA shows a different rearrangement compared to ancestral insect gene order (trnI-trnQ-trnM). Almost all tRNAs have a typical cloverleaf secondary structure except for trnS1 (AGN) which lacks the dihydrouridine arm. At the beginning of the control region, we observed a conserved polyT", motif "ATTTA" and microsatellite (TA)n element. There are 21 intergenic regions and five overlapping regions ranging from 1 to 73 bp and 1 to 8 bp, respectively. The phylogenetic relationships based on nucleotide sequences of 13 PCGs using Maximum likelihood method showed the family level relationships as (Notodontidae + (Euteliidae + Noctuidae + (Erebidae + Nolidae))). The present study represents the similarity to phylogenetic analysis of Noctuoidea mitogenome. Moreover, the family Erebidae is the sister to the families of (Euteliidae + Noctuidae + Nolidae).

Abstract
In this study, the complete mitochondrial genome of a white tussock moth, Laelia suffusa (Walker, 1855) (Lepidoptera: Erebidae, Lymantriinae), was sequenced and annotated. The genome sequence was 15,502 bp in length and comprised 13 PCGs, 2 rRNAs, 22 tRNAs, and a single noncoding control region (CR). The nucleotide composition of the genome was highly A + T biased, accounting for 79.04% of the whole genome and with a slightly positive AT skewness (0.015). Comparing the gene order with the basal species of Lepidoptera, a typical trnM rearrangement was detected in the mitogenome of L. suffusa. Besides, the trnM rearrangement was found at the head of trnI and trnQ, rather than at the back. The 13 PCGs used ATN as their start codons, except for the cox1 which used CGA. Out of the 22 tRNAs, only 1 tRNA (trnS1) failed to fold in a typical cloverleaf secondary structure. The conserved motif 'ATAGA + poly-T' was detected at the start of the control region which was similar to other Lepidoptera species. In total, 10 overlapping regions and 19 intergenic spacers were identified, ranging from 1 to 41 and 2 to 73 bp, respectively. Phylogenetic analysis showed that Lymantriinae was a monophyletic group with a high support value and L. suffusa was closely related to tribe Orgyiini (Erebidae, Lymantriinae). Moreover, the phylogenetic relationship of Noctuoidea (Lepidoptera) species was reconstructed using two datasets (13 PCGs and 37 genes) and these supported the topology of (Notodontidae + (Erebidae + (Nolidae + (Euteliidae + Noctuidae)))).

Abstract
Mitochondrial genomes (mitogenomes) have been widely used for studies on phylogenetic relationships and molecular evolutionary biology. Here, the complete mitogenome sequence of Spilosoma lubricipedum (Noctuoidea: Erebidae: Arctiinae) was determined (total length 15,375 bp) and phylogenetic analyses S. lubricipedum were inferred from available noctuid sequence data. The mitogenome of S. lubricipedum was found to be highly A + T-biased (81.39%) and exhibited negative AT- and GC-skews. All 13 protein-coding genes (PCGs) were initiated by ATN codons, except for cox1 with CGA. All tRNAs exhibited typical clover-leaf secondary structures, except for trnS1. The gene order of the S. lubricipedum mitogenome was trnM-trnI-trnQ-nad2. The A + T-rich region of S. lubricipedum contained several conservative features common to noctuid insects. Phylogenetic analysis within Noctuoidea was carried out based on mitochondrial data. Results showed that S. lubricipedum belonged to Erebidae and the Noctuoidea insects could be divided into five well-supported families (Notodontidae + (Erebidae + (Nolidae + (Euteliidae + Noctuidae)))).

Abstract
In this study, the mitochondrial genome (mitogenome) of Holothuria fuscocinerea was unraveled to be 15,890 bp in length, containing 13 protein-coding genes (PCGs), 22 tRNA genes, and 2 rRNA genes. The PCGs were initiated by four initiation codons (ATG, TAC, ATC, and ATA). Only one PCG (nad6) and five tRNA genes (tRNASer(UCN), tRNAGln, tRNAAla, tRNAVal, and tRNAAsp) were encoded on the light chain, and the other genes were encoded on the heavy chain. A phylogenetic tree constructed with 16S rRNA sequences showed that H. fuscocinerea is most closely related to H. leucospilota.

Ascoviruses are large, enveloped DNA viruses that induce remarkable changes in cellular architecture during which the cell is partitioned into numerous vesicles for viral replication. Previous studies have shown that these vesicles arise from a process resembling apoptosis yet which differs after nuclear lysis in that mitochondria are not degraded but are modified by the virus, changing in size, shape, and motility. Moreover, infection does not provoke an obvious innate immune response. Thus, we used in vivo RNA sequencing to determine whether infection by the Spodoptera frugiperda ascovirus 1a (SfAV-1a) modified expression of host mitochondrial, cytoskeletal, and innate immunity genes. We show that transcripts from many mitochondrial genes were similar to those from uninfected controls, whereas others increased slightly during vesicle formation, including those for ATP6, ATP8 synthase, and NADH dehydrogenase subunits, supporting electron microscopy (EM) data that these organelles were conserved for virus replication. Transcripts from 58 of 106 cytoskeletal genes studied increased or decreased more than 2-fold postinfection. More than half coded for mitochondrial motor proteins. Similar increases occurred for innate immunity transcripts and their negative regulators, including those for Toll, melanization, and phagocytosis pathways. However, those for many antimicrobial peptides, such as moricin, increased more than 20-fold. In addition, transcripts for gloverin-3, spod_x_tox, Hdd23, and lebocin, also antimicrobial, increased more than 20-fold. Interestingly, a phenoloxidase inhibitor transcript increased 12-fold, apparently to interfere with melanization. SfAV-1a destroys most fat body cells by 7 days postinfection, so innate immunity gene transcripts apparently occur in remaining cells in this tissue and possibly other major tissues, namely, epidermis and tracheal matrix.IMPORTANCE Ascoviruses are large DNA viruses that infect insects, inducing a cellular pathology that resembles apoptosis but which differs by causing enormous cellular hypertrophy followed by cleavage of the cell into numerous viral vesicles for replication. Previous EM studies suggest that mitochondria are important for vesicle formation. Transcriptome analyses of Spodoptera frugiperda larvae infected with SfAV-1a showed that mitochondrial transcripts were similar to those from uninfected controls or increased slightly during vesicle formation, especially for ATP6, ATP8 synthase, and NADH dehydrogenase subunits. This pattern resembles that for chronic disease-inducing viruses, which conserve mitochondria, differing markedly from viruses causing short-term viral diseases, which degrade mitochondrial DNA. Though mitochondrial transcript increases were low, our results demonstrate that SfAV-1a alters host mitochondrial expression more than any other virus. Regarding innate immunity, although SfAV-1a destroys most fat body cells, certain immunity genes were highly upregulated (greater than 20-fold), suggesting that these transcripts may originate from other tissues.

Abstract
Phauda flammans Walker belongs to Phaudidae (Lepidoptera), which is a holometabolous and leaf-eating pest that harms trees. So far, there is no mitochondrial (mt) genome reported of Phaudidae. Herein, we sequenced and annotated the complete mt genome of P. flammans representing the first mt genome of Phaudidae and predicted the secondary structures of its RNAs in this study. This mt genome is 15470 bp long consisting of 13 protein coding genes (PCGs), 22 tRNAs, 2 rRNAs and the control region, which are usually conserved in insects. Most PCGs used the standard ATN start codons and complete TAA/TAG termination codons. Almost all of tRNA genes exhibited cloverleaf secondary structures except that the dihydorouridine (DHU) arm of tRNASer(AGN) was absent. The phylogenetic analyses using both Bayesian inference (BI) and maximum likelihood (ML) methods all supported that Phaudidae was a single family being the sister group to Zygaenidae. More mt genomes are needed to better understand the phylogenetic relationships within Zygaenoidea in the future.

Abstract
The Trigonidiidae, a family of crickets, comprises 981 valid species with only one mitochondrial genome (mitogenome) sequenced to date. To explore mitogenome features of Trigonidiidae, six mitogenomes from its two subfamilies (Nemobiinae and Trigonidiinae) were determined. Two types of gene rearrangements involving a trnN-trnS1-trnE inversion and a trnV shuffling were shared by Trigonidiidae. A long intergenic spacer was observed between trnQ and trnM in Trigonidiinae (210-369 bp) and Nemobiinae (80-216 bp), which was capable of forming extensive stem-loop secondary structures in Trigonidiinae but not in Nemobiinae. The anticodon of trnS1 was TCT in Trigonidiinae, rather than GCT in Nemobiinae and other related subfamilies. There was no overlap between nad4 and nad4l in Dianemobius, as opposed to a conserved 7-bp overlap commonly found in insects. Furthermore, combined comparative analysis and transcript verification revealed that nad1 transcripts ended with a U, corresponding to the T immediately preceding a conserved motif GAGAC in the superfamily Grylloidea, plus poly-A tails. The resultant UAA served as a stop codon for species lacking full stop codons upstream of the motif. Our findings gain novel understanding of mitogenome structural diversity and provide insight into accurate mitogenome annotation.

Abstract
Scytalidium auriculariicola is the causative pathogen of slippery scar disease in the cultivated cloud ear fungus, Auricularia polytricha. In the present study, the mitogenome of S. auriculariicola was sequenced and assembled by next-generation sequencing technology. The circular mitogenome is 96,857 bp long and contains 56 protein-coding genes, 2 ribosomal RNA genes, and 30 transfer RNA genes (tRNAs). The high frequency of A and T used in codons contributed to the high AT content (73.70%) of the S. auriculariicola mitogenome. Comparative analysis indicated that the base composition and the number of introns and protein-coding genes in the S. auriculariicola mitogenome varied from that of other Leotiomycetes mitogenomes, including a uniquely positive AT skew. Five distinct groups were found in the gene arrangements of Leotiomycetes. Phylogenetic analyses based on combined gene datasets (15 protein-coding genes) yielded well-supported (BPP = 1) topologies. A single-gene phylogenetic tree indicated that the nad4 gene may be useful as a molecular marker to analyze the phylogenetic relationships of Leotiomycetes species. This study is the first report on the mitochondrial genome of the genus Scytalidium, and it will contribute to our understanding of the population genetics and evolution of S. auriculariicola and related species.

Abstract
Five species of noctuid moths, Helicoverpa armigera, H. punctigera, H. assulta, H. zea, and H. gelotopoeon, are major agricultural pests inhabiting various and often overlapping global distributions. Visual identification of these species requires a great deal of expertise and misidentification can have repercussions for pest management and agricultural biosecurity. Here, we report on the complete mitochondrial genomes of H. assulta assulta and H. assulta afra, H. gelotopoeon, H. punctigera, H. zea, and H. armigera armigera and H. armigera conferta' assembled from high-throughput sequencing data. This study significantly increases the mitogenome resources for these five agricultural pests with sequences assembled from across different continents, including an H. armigera individual collected from an invasive population in Brazil. We infer the phylogenetic relationships of these five Helicoverpa species based on the 13 mitochondrial DNA protein-coding genes (PCG's) and show that two publicly available mitogenomes of H. assulta (KP015198 and KR149448) have been misidentified or incorrectly assembled. We further consolidate existing PCR-RFLP methods to cover all five Helicoverpa pest species, providing an updated method that will contribute to species differentiation and to future monitoring efforts of Helicoverpa pest species across different continents. We discuss the value of Helicoverpa mitogenomes to assist with species identification in view of the context of the rapid spread of H. armigera in the New World. With this work, we provide the molecular resources necessary for future studies of the evolutionary history and ecology of these species.

Abstract
The mitochondrial genome (mitogenome) plays an important role in revealing molecular evolution. In this study, the complete mitogenome of Grammodes geometrica (G. geometrica) (Lepidoptera: Erebidae) was sequenced and characterized. The nucleotide composition of the genome is highly A + T biased, accounting for 80.49%. Most protein-coding genes (PCGs) are initiated by ATN codons except for the cytochrome oxidase subunit 1 (cox1) gene, which was initiated by CGA. The order and orientation of genes with the order trnM-trnI-trnQ-nad2 is a typical rearrangement compared with those ancestral insects in which trnM is located between trnQ and nad2. Most tRNA genes were folded into the typical cloverleaf structure except for trnS1 (AGN). The A + T-rich region contains the conserved motif "ATAGA" followed by a 19 bp poly-T stretch, which was also observed in other Noctuoidea species. In addition, we reconstructed phylogenetic trees among the nucleotide alignments of five families of Noctuoidea species except the Oenosandridae. Finally, we achieved a well-supported tree, which showed that G. geometrica belongs to the Erebidae family. Moreover, the relationships at the family-level can be displayed as follows: (Notodontidae + (Erebidae + (Nolidae + (Euteliidae + Noctuidae)))).

Abstract
In this study, mitogenome of Somena scintillans (Lepidoptera: Erebidae) were sequenced and compared with other Noctuoidea species. The mitogenome is 15,410 base pairs in length. All 13 protein-coding genes (PCGs) are initiated by ATN codons except cox1 with CGA and all of PCGs terminate with TAA except nad4 with TAG. The codons ACG and CGC are absent. All the tRNA genes could be folded into the typical cloverleaf secondary structure except the trnS1 which not only loses dihydrouridine (DHU) arm but also mutates its anticodon into TCT. In the AT-rich region of the mitogenome the motif 'ATAGA' mutates to 'ATATA' and two copies of 161 bp-tandem repeats and two 'TA' short tandem repeats are founded. Phylogenetic analyses showed that S. scintillans is clustered into subfamily Lymatriinae. The phylogenetic relationships within Noctuoidea is (((Nolidae + (Euteliidae + Noctuidae)) + Erebidae) + Notodontidae).

Abstract
The fall armyworm (FAW) Spodoptera frugiperda (J. E. Smith) is a species native to the Americas. This polyphagous lepidopteran pest was first reported in Nigeria and the Democratic Republic of São Tomé and Principe in 2016, but its presence in eastern Africa has not been confirmed via molecular characterisation. In this study, FAW specimens from western and central Uganda were identified based on the partial mtDNA COI gene sequences, with mtDNA COI haplotypes matching those identified in Nigeria and São Tomé. In this study, we sequence an additional partial mtDNA Cyt b gene and also the partial mtDNA COIII gene in Ugandan FAW samples. We detected identical mitochondrial DNA haplotypes for both the mtDNA Cyt b and COI partial genes, while combining the mtDNA COI/Cyt b haplotypes and mtDNA COIII haplotypes enabled a new maternal lineage in the Ugandan corn-preferred FAW samples to be identified. Our results suggested that the African incursions of S. frugiperda involved at least three maternal lineages. Recent full genome, phylogenetic and microsatellite analyses provided evidence to support S. frugiperda as likely consisted of two sympatric sister species known as the corn-preferred and rice-preferred strains. In our Ugandan FAW populations, we identified the presence of mtDNA haplotypes representative of both sister species. It is not known if both FAW sister species were originally introduced together or separately, and whether they have since spread as a single population. Further analyses of additional specimens originally collected from São Tomé, Nigeria and throughout Africa would be required to clarify this issue. Importantly, our finding showed that the genetic diversity of the African corn-preferred FAW species is higher than previously reported. This potentially contributed to the success of FAW establishment in Africa. Furthermore, with the additional maternal lineages detected, there is likely an increase in paternal lineages, thereby increasing the diversity of the African FAW population. Knowledge of the FAW genetic diversity will be needed to assess the risks of introducing Bt-resistance traits and to understand the FAW incursion pathways into the Old World and its potential onward spread. The agricultural implications of the presence of two evolutionary divergent FAW lineages (the corn and the rice lineage) in the African continent are further considered and discussed.

The complete mitochondrial genome of Euproctis similis (Lepidoptera: Noctuoidea: Erebidae) and phylogenetic analysis. Int J Biol Macromol 2017; 105:219-227. [PMID: 28698080 DOI: 10.1016/j.ijbiomac.2017.07.033] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2017] [Revised: 07/05/2017] [Accepted: 07/05/2017] [Indexed: 11/22/2022]
Abstract
The mitochondrial genome (mitogenome) can provide information for phylogenetic analyses and evolutionary biology. We sequenced, annotated, and characterized the mitogenome of Euproctis similis. The complete mitogenome is 15,437bp in length, containing 13 protein-coding genes (PCGs), 22 transfer RNA genes, two ribosomal RNA genes, and a control region (A+T-rich region). The A+T content in the mitogenome was 80.16%. All PCGs use standard ATN as a start codon, with the exception of cytochrome c coxidase 1 (cox1) with CGA. A gene rearrangement (trnM) was found. All transfer RNA (tRNA) genes have a typical clover-leaf structure except for trnS1 (AGN). Phylogenetic analysis was performed using Bayesian Inference and Maximum Likelihood based on the amino acid and nucleotide sequences of 13 mitochondrial PCGs. The well-supported phylogenetic relationships can be generally described as: Notodontidae+(Erebidae+(Nolidae+(Euteliidae+Noctuidae))). The tree support that E. similis shares a close ancestry with Erebidae insects. Our results indicate that Erebidae is a sister group to the other families (Euteliidae, Nolidae, and Noctuidae).

A transfer RNA gene rearrangement in the lepidopteran mitochondrial genome. Biochem Biophys Res Commun 2017; 489:149-154.

Abstract
Gene arrangements in the mitochondrial genomes (mitogenomes) of insects are conserved across the major lineages, but can be rearranged within derived groups and may provide valuable phylogenetic characters. In this study, we sequenced the entire mitogenome of Parasa consocia, a moth of the family Limacodidae (Lepidoptera: Zygaenoidea). Compared with other lepidopterans and ancestral insects, the P. consocia mitogenome features a transfer RNA gene arrangement novel among lepidopterans between the ND3 and ND5 genes: RANSEF (the underline signifies an inverted gene), which differs from the ARNSEF arrangement of ancestral insects. This rearrangement can be explained by the tandem duplication-random loss model. We inferred a phylogenetic hypothesis for the lepidopteran superfamily based on mitochondrial amino-acid sequences using the Bayesian-inference and maximum-likelihood methods. Our results showed that P. consocia belongs to the Zygaenoidea superfamily and supported the following phylogenetic relationship: Yponomeutoidea + (Tortricoidea + Zygaenoidea + (Papilionoidea + (Pyraloidea + (Noctuoidea + (Geometroidea + Bombycoidea)))))). Comparative analyses indicated that mitogenomes are a useful phylogenetic tool at the subfamily level within the order Lepidoptera. Our findings also suggest that mitogenomes are likely to represent a valuable tool for systematics in other groups of lepidopterans.

Abstract
The bluish yellow lappet moth, Trabala vishnou guttata is an extraordinarily important pest in China. The complete mitochondrial genome is sequenced and determined firstly, which is based on traditional PCR amplification and primer walking methods with a length of 15,281 bp, including 13 protein-coding (PCG) genes, 22 transfer RNA (rRNA) genes, two ribosomal RNA (tRNA) genes, and an A + T-rich region. The gene order and orientation of the T. vishnou guttata mitogenome were identical to the other sequenced Lasiocampidae species. The overall nucleotide composition of T. vishnou guttata is A (40.27 %), T (40.59 %), C (11.58 %) and G (7.56 %), respectively. All the PCGs initiate with the three orthodox start codons ATN except for coxI with CGA start codon. Three PCGs (coxI, coxII and nad4) used incomplete stop codon T, while the other 10 PCGs terminate with complete stop codon TAA. All tRNA genes have a typical clover-leaf structure except for the absence of a dihydrouridine arm in trnS (AGN). The length of A + T-rich region is 383 bp. Phylogeny is established to reveal the genetic relationship between T. vishnou guttata and other lepidopteran species based on 13 PCGs nucleotide sequences of the sequenced species (32 taxa) by Maximum likelihood and Bayesian methods. Phylogenetic analyses presents that T. vishnou guttata and its closely related species (Dendrolimus taxa) are clustered on Lasiocampidae group. It is a sister clade relationship between Lasiocampidae and other families in Bombycoidea with a bootstrap value of 83 % and a posterior probability of 0.75. This study supports that Lasiocampidae may be independent from Bombycoidea.

Abstract
The mitochondrial genome (mitogenome) provides important information for understanding molecular evolution and phylogeny. To determine the systematic status of the family Limacodidae within Lepidoptera, we infer a phylogenetic hypothesis based on the complete mitogenome of Monema flavescens (Lepidoptera: Limacodidae). The mitogenome of M. flavescens is 15,396 base pairs (bp), and includes 13 protein-coding genes (PCGs), two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and a control region (CR). The AT skew of this mitogenome is slightly negative and the nucleotide composition is also biased towards A + T nucleotides (80.5%). All PCGs are initiated by ATN codons, except for the cytochrome c oxidase subunit 1 (cox1) gene, which is initiated by CGA. All tRNAs display the typical clover-leaf structure characteristic of mitochondrial tRNAs, with the exception of trnS1 (AGN). The mitogenome CR is 401 bp and consists of several features common to Lepidoptera. Phylogenetic analysis using Bayesian Inference (BI) and Maximum Likelihood (ML) based on nucleotide and amino acid sequences of 13 mitochondrial PCGs indicates that M. flavescens belongs to Zygaenoidea. We obtain a well-supported phylogenetic tree consisting of Yponomeutoidea + (Tortricoidea + Zygaenoidea + (Papilionoidea + (Pyraloidea + (Noctuoidea + (Geometroidea + Bombycoidea))))).
