“…The mitogenome of C. exigua was a closed-circular molecule of 15,262 in length ( Table 1 ), which was within the range observed in the sequenced other Pyraloidea mitogenomes available with the size ranging from 15,110 bp in Maruca testulalis ( Zou et al 2016 ) to 15,594 bp in Ephestia kuehniella ( Zhu et al 2018 ). Annotation of the C. exigua mitogenome indicated that the structure and orientation of the 13 PCGs, 22 tRNA genes, 2 rRNA genes, and a noncoding region (A+T-rich control region) were typical of and similar to the other closely related pyraloid species ( Yang et al 2018 , Zhu et al 2018 ). Nine PCGs ( nad2 , nad3 , nad6 , cox1-3 , atp6 , atp8 , cytb ), 14 tRNAs, and the control region were located on the major J-strand.…”

“…Similar to other pyraloid species, the C. exigua mitogenome nucleotide composition was bias toward adenine and thymine (accounting for 81.6%: A = 40.5%, T = 41.1%, C = 10.9% G = 7.5%) ( Yang et al 2018 , Zhu et al 2018 ). The nucleotide bias was also reflected in the codon usage.…”

“…All the 22 identified tRNA genes in C. exigua mitogenome were folded into the typical clover-leaf structure of mitochondrial tRNAs, except for trnS1 (AGN) in which the dihydrouridine (DHU) arm failed to form a stable stem-loop structure ( Supp Table 3 [online only] ). The exception trnS1 had been observed in many Pyraloidea and other insect mitogenomes ( Zhang et al 2016 , Zhang and Ye 2017 , Yang et al 2018 , Zhu et al 2018 ). The length and base composition of these tRNAs were similar to other pyralids ( Yang et al 2018 , Zhu et al 2018 ).…”

Rice leaffolders are important pests on rice in Asia, Oceania, and Africa, causing serious loss to rice production. There are two main rice leaffolders in China, namely Cnaphalocrocis medinalis (Guenée) and C. exigua (Butler) with the former having the ability of long-distance migration. To reveal the differences in the mitochondrial genomes (mitogenome) between them, we compared the completed mitogenome of C. exigua with three C. medinalis individuals. Although phylogenetic analysis based on the mitogenomic data strongly supported the close relationship between these two species, many differences were still being revealed. The results showed that the mitogenome of C. exigua was shorter in length (15,262 bp) and slight lower in AT content than that of C. medinalis. Except for the different start codons of nad3 and nad6 gene, we also found the cox1 gene had a typical start codon ‘ATG’ which suggested that the starting position of this gene must be reconsidered in the entire superfamily Pyraloidea. All tRNAs have a typical clover-leaf structure, except for the dihydrouridine (DHU) stem losing of trnS1, which has the atypical anticondon ‘TCT’ instead of ‘GCT’ in C. medinalis and most Pyraloidea species. Two intergenic regions (between trnY and cox1, nad3 and trnA) featured by AT repeats were only found in C. medinalis and even rarely appeared in reported Pyraloidea species. Furthermore, regardless of interspecific comparison or intraspecific comparison of these two species, protein coding genes, especially the atp8 genes, had quite different evolutionary rates.

To understand mitogenome characteristics and reveal phylogenetic relationships of the genus Ostrinia, including several notorious pests of great importance for crops, we sequenced the complete mitogenomes of four species: Ostrinia furnacalis (Guenée, 1854), Ostrinia nubilalis (Hübner, 1796), Ostrinia scapulalis (Walker, 1859) and Ostrinia zealis (Guenée, 1854). Results indicate that the four mitogenomes-O. furnacalis, O. nubilalis, O. scapulalis, and O. zealis-are 15,245, 15,248, 15,311, and 15,208 bp in size, respectively. All four mitogenomes are comprised of 37 encoded genes and a control region. All 13 protein-coding genes (PCGs) initiate with ATN and terminate with TAN, with the exception of cox1 that starts with CGA, and cox1, cox2, and nad5 that terminate with an incomplete codon T. All transfer RNA genes (tRNAs) present the typical clover-leaf secondary structure except for the trnS1 (AGN) gene. There are some conserved structural elements in the control region. Our analyses indicate that nad6 and atp6 exhibit higher evolution rates compared to other PCGs. Phylogenetic analyses based on mitogenomes using both maximum likelihood (ML) and Bayesian inference (BI) methods revealed the relationship (O. palustralis + (O. penitalis + (O. zealis + (O. furnacalis + (O. nubilalis + O. scapulalis))))) within Ostrinia. Insects 2020, 11, 232 2 of 15East Asia, and Northwestern Africa. Within this third species group, three subgroups are recognized according to the differences in male mid-tibia. The first subgroup contains four species including O. nubilalis and O. furnacalis with smaller mid-tibia and lacking any groove or scales. The second subgroup includes two species, namely O. kurentzovi (Mutuura and Munroe, 1970) and O. narynensis (Mutuura and Munroe, 1970), with a moderately dilated tibia and a fringe of enlarged curved scales. The third subgroup consists of four species, including O. scapulalis and O. zealis, possessing a strongly dilated tibia and massive scales in the groove. Mutuura and Munroe (1970) stated that the three species groups within the genus Ostrinia are monophyletic and indicated that O. penitalis is the most primitive species. The second group was defined as monophyletic because the members share potential synapomorphies in male genitalia [2]. The third species group has been intensively studied on the basis of their morphology, pheromones, and DNA sequence. Based on the complexity of the male tibia, Mutuura and Munroe (1970) considered that the species with the smallest tibia is the most primitive, then the species with the medium tibia are intermediate, and finally, the species with the large tibia and massive tuft are the most derived.Frolov (1981, 1984) stated that the variation in the male mid-tibia was determined by two alleles. The Mt and Mt + were two alleles located on autosomes and controlled the size of the mid-tibia, while i and i + were two alleles located on Z-sex-linked chromosomes and controlled the groove appearance. Mt/Mt + and i/i + follow a Mendelian inheritance pattern ...

Loxostege turbidalis, Loxostege aeruginalis, Pyrausta despicata, and Crambus perlellus belong to Crambidae, Pyraloidea. Their mitochondrial genomes (mitogenomes) were successfully sequenced. The mitogenomes of L. turbidalis, L. aeruginalis, P. despicata, and C. perlellus are 15 240 bp, 15 339 bp, 15 389 bp, and 15 440 bp. The four mitogenomes all have a typical insect mitochondrial gene order, including 13 protein‐coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and one A + T rich region (control region). The PCGs are initiated by the typical ATN codons, except CGA for the cox1 gene. Most PCGs terminate with common codon TAA or TAG, the incomplete codon T is found as the stop codon for cox2, nad4, and nad5. Most tRNA genes exhibit typical cloverleaf structure, except trnS1 (AGN) lacking the dihydrouridine (DHU) arm. The secondary structure of rRNA of four mitogenomes were predicted. Poly‐T structure and micro‐satellite regions are conserved in control regions. The phylogenetic analyses based on 13 PCGs showed the relationships of subfamilies in Pyraloidea. Pyralidae, and Crambidae are monophyletic, respectively. Pyralidae comprises four subfamilies, which form the following topology with high support values: (Galleriinae + ((Pyralinae + Epipaschiinae)+ Phycitinae)). Crambidae includes seven subfamilies and is divided into two lineages. Pyraustinae and Spilomelinae are sister groups of each other, and form the “PS clade.” Other five subfamilies (Crambinae, Acentropinae, Scopariinae, Schoenobiinae, and Glaphyriinae) form the “non‐PS clade” in the Bayesian inference tree. However, Schoenobiinae is not grouped with the other four subfamilies and located at the base of Crambidae in two maximum likelihood trees.
