Cowpea ( Vigna unguiculata (L.) Walp.), as an economical crop, is one of the important pillar industries of rural revitalization strategy in China. However, cowpea planting in China is often infested and damaged by many insects during growth, especially in Hainan region with a warm and wet tropical climate. Traditional monitoring methods with techn...

Micromelalopha sieversi (Staudinger, 1892) is a significant pest of Poplar trees in China. In this study, we used high-throughput sequencing to sequence the whole mitochondrial genome of M. sieversi. The length of the genome was 15,373 base pairs. The nucleotide composition was 39.8%, 11.5%, 8.0%, and 40.7% for A, C, G, and T, respectively. We used...
We performed the first sequencing of the complete mitogenome of Botyodes diniasalis by high-throughput sequencing. A circular DNA molecule of 15,219 bp in size, encoding 2 rRNAs, 22 tRNAs, and 13 PCGs, contains a non-coding AT-rich region. The overall nucleotide composition of the genome is A (39.5%), T (41.3%), C (11.3%), and G (7.8%). Phylogeneti...
The small, relict-like moth family Endromidae is well-established within the superfamily Bombycoidea, but relationships within the family have remained vague for the last decade, primarily due to very limited taxon sampling. This resulted in the explicit removal of all internal suprageneric classification by Zwick et al. (2011) when they synonymize...
As one of the largest single-radiation sources of phytophagous insects, the higher level phylogeny of lepidopteran lineages has been debated for decades, especially the early divergences of nonditrysia. Here, we use 74 mitochondrial genomes representing seven nonditrysian superfamilies, including the newly sequenced mitochondrial genomes of eight f...
Gene families, which are parts of a genome’s information storage hierarchy, play a significant role in the development and diversity of multicellular organisms. Several studies have focused on the characteristics of gene families, such as function, homology, or phenotype. However, statistical and correlation analyses on the distribution of gene fam...
Background
A robust and stable phylogenetic framework is a fundamental goal of evolutionary biology. As the third largest insect order following by Diptera and Coleoptera in the world, lepidoptera (butterflies and moths) play a central role in almost every terrestrial ecosystem as the indicators of environmental change and serve as important models...
Lepidoptera has rich species including many agricultural pests and economical insects around the world. The mitochondrial genomes (mitogenomes) were utilized to explore the phylogenetic relationships between difference taxonomic levels in Lepidoptera. However, the knowledge of mitogenomic characteristics and phylogenetic position about superfamily-...
The subfamily Bombycinae Latreille, [1802] is an important silk‐producing group, including well‐known economical insects. Although there are many studies on the development of these economic insects, the relationships between genera/species of this subfamily are still unclear. Two data sets of mitochondrial genomes, 13 protein‐coding genes (13PCGs)...

Parapoynx crisonalis (Walker, 1859) (Lepidoptera: Crambidae) is a major pest of aquatic vegetables and aquatic landscape plants. It has been responsible for causing considerable economic damage to water chestnut (Trapa natans) plants. In the Changsha vicinity of China, P. crisonalis has five generations a year. Populations of P. crisonalis were rel...

The larvae of Parapoynx crisonalis (Walker, 1859) is an important pest in China, causing significant damage on the aquatic crops. To improve the management of P. crisonalis and demonstrate the phylogenetic relationships amongst Pyraloidea, the complete mitochondrial genome (mitogenome) sequences of four aquatic pyralid moths, which belong to three...

Parapoynx crisonalis is an important pest of many aquatic vegetables including water chestnuts. Understanding the relationship between temperature variations and the population growth rates of P. crisonalis is essential to predicting its population dynamics in water chestnuts ponds. These relationships were examined in this study based on the age-s...

... A nonstandard initiation codon GTA was observed in ND1 in the mitogenome of white N. patrioticus. Unusual initiation codons have previously been reported in many animals, including ND2 of Sellanucheza jaegeri, which starts with TTG, and COXI of Botyodes diniasalis, which starts with CGA [35,36]. The termination codons of the two mitogenomes are identical; 10 PCGs (COXI, COXII, ATP8, ATP6, COXIII, ND6, CYTB, ND4L, ND4, ND2) used TAN (TAA, TAG) as termination codon, and the other PCGs (ND3, ND1, ND5) used T as the termination codon. ...
... This is the first phylogenetic study (using the mt genome) of A. conjugella in the Argyresthiidae family, which belongs to the Yponomeutoidea superfamily. Various studies tried to resolve phylogenetic tree of Lepidoptera using mitochondrial genomes, nucleotide alignments, amino acid alignments and transcriptomes and target enrichment approaches [6,7,9,[17][18][19][20][21]58]. However, inadequate node support hindered research that attempted to unravel relationships among superfamilies [17][18][19][20][21]. ...

... Mitochondria, which possess their own genomes, are distinctive organelles present in almost all eukaryotic cells (Osellame et al. 2012;Chen et al. 2022). Animal mitogenome is a double-stranded circular DNA molecule that encodes 37 conserved genes, including 13 protein-coding genes (PCGs), 2 ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and a control region (A + T-rich region) that regulate its transcription and replication (Boore 1999;Taanman 1999;Cameron 2014). ...

... It cannot be ruled out that similar adaptations occurred multiple times within the Crambidae. A recent study by Chen et al. (2017a), involving molecular data, suggests that the Nymphula-type caterpillar (with hydrophobic cuticle and open spiracle system) evolved from the Parapoynx-type larva (with tracheal gills and closed spiracles). Although the current state of biodiversity inventories in different regions of the world preclude the completion of any comprehensive zoogeographical studies; it is worth mentioning that only two genera, Parapoynx and Elophila, are cosmopolitan (Mey and Speidel, 2008). ...

... In order to develop and implement appropriate management strategies, it becomes essential to accurately predict the population dynamics of this pest under various environmental conditions. Numerous environmental factors, such as relative humidity (Broufas et al. 2009) and photoperiod (Chen et al. 2017a), play a significant role in shaping the population dynamics of insects, with temperature being one of the most critical factor (Chen et al. 2017b). Temperature exerts profound effects on the development, survival, fecundity, and intrinsic rate of most insect populations (Broufas et al. 2009). ...
