Chromosome-Level Genome Assembly of Voss (Coleoptera: Attelabidae): Insights into Evolution and Behavior.

Attelabidae insects have attracted much attention due to their unique leaf rolling behavior before oviposition. However, the lack of genomic data makes it difficult to understand the molecular mechanism behind their behavior and their evolutionary relationship with other species. To address this gap, we utilized Illumina and Nanopore sequencing platforms along with Hi-C technology to establish a highly accurate whole genome of at the chromosome level.

The first chromosome-level genome of the stag beetle Dorcus hopei Saunders, 1854 (Coleoptera: Lucanidae).

Stag beetles (Coleoptera: Lucanidae) represent a significant saproxylic assemblage in forest ecosystems and are noted for their enlarged mandibles and male polymorphism. Despite their relevance as ideal models for the study of exaggerated mandibles that aid in attracting mates, the regulatory mechanisms associated with these traits remain understudied, and restricted by the lack of high-quality reference genomes for stag beetles. To address this limitation, we successfully assembled the first chromosome-level genome of a representative species Dorcus hopei.

Complete mitogenome and phylogenetic significance of Metoecus javanus (Pic, 1913) (Coleoptera: Ripiphoridae) from Southwest China, with notes on morphological traits of adult and immature stages.

Wedge-shaped beetles (Ripiphoridae) not only exhibit enigmatic morphological and biological traits but also disputable phylogenetic positions. At present, however, genetic information regarding this family remains limited. In this study, we report on the complete mitogenome of one ripiphorid beetle, Metoecus javanus (Pic, 1913), from Southwest China, as well as its different developmental stages, populations, and morphological variability.

Genome-wide survey of open chromatin regions in two swallowtail butterflies Papilio machaon and P. bianor.

Papilio machaon was assigned as the type species for all butterflies by Linnaeus and P. bianor is a congener but exhibits a great difference in morphology (especially larva and adult color pattern) and larval host plants from P. machaon.

High-quality reference genomes of swallowtail butterflies provide insights into their coloration evolution.

Swallowtail butterflies (Papilionidae) are a historically significant butterfly group due to their colorful wing patterns, extensive morphological diversity, and phylogenetically important position as a sister group to all other butterflies and have been widely studied regarding ecological adaption, phylogeny, genetics, and evolution. Notably, they contain a unique class of pigments, i.e.

 sp. nov.: A new twisted-wing parasite species (Strepsiptera, Xenidae) from Gaoligong Mountains, Southwest China.

Here we report a new twisted-wing parasite species of the family Xenidae based on both morphological and molecular evidence. By using nearly complete mitogenomes, we confirmed the twisted-wing parasites on two wasps ( and ) (China: Yunnan) as the same species, and associated its neotenic females and alate males. Combining the mitogenomic data () and morphological traits, this species was identified to be a new species of the genus , namely Dong, Liu & Li, Detailed descriptions and illustrations are provided for the new species.

Chromatin accessibility profiling provides insights into larval cuticle color and adult longevity in butterflies.

Butterflies are diverse in virtually all aspects of their ontogeny, including morphology, life history, and behavior. However, the developmental regulatory mechanisms underlying the important phenotypic traits of butterflies at different developmental stages remain unknown. Here, we investigated the developmental regulatory profiles of butterflies based on transposase accessible chromatin sequencing (ATAC-seq) at three developmental stages in two representative species ( and ).

The mitochondrial genome of a leaf insect (Phasmatodea: Phylliidae) in Southeast Asia.

The nearly complete mitochondrial genome (mitogenome) of , a typical leaf mimic insect in Phasmatodea, was obtained in this study. This mitogenome is 17,222 bp in length and contains 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs) and almost complete control regions. All PCGs initiate with 'ATN' except for that uses 'TTG' as the start codon, and terminate with 'TAA' except for that uses a single 'T' residue as the stop codon.

The mitochondrial genome of one 'twisted-wing parasite' cf. (Insecta, Strepsiptera, Xenidae) from Gaoligong Mountains, Southwest of China.

The nearly complete mitochondrial genome (mitogenome) of cf. , one twisted-wing parasite on wasp from Southwest of China, is described in this study. The total length of this mitogenome is 16,717 bp, containing 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs) and an incomplete A + T-rich control region .

Genome-wide SNP discovery and genetic diversity evaluation of Liangshan cattle in China.

Liangshan cattle are a very small indigenous breed with adult weight of less than 300 Kg and have been mainly distributed in the Liangshan Yi Autonomous Prefecture of Southwestern Sichuan, China. Due to its long-term adaptation to local environments, Liangshan cattle is a valuable genetic resource and should be paid with more attentions. However, the genetic diversity of Liangshan cattle have not been specifically investigated yet, which would be required when designing the appropriate conservation and utilization programs.
