Abstract Background Metazoan adenosine-to-inosine (A-to-I) RNA editing resembles A-to-G mutation and increases proteomic diversity in a temporal-spatial manner, allowing organisms adapting to changeable environment. The editomes many major animal clades remain unexplored, hampering the understanding on evolution adaptation of this essential post-transcriptional modification. Methods We assembled chromosome-level genome Coridius chinensis belonging Hemiptera, fifth largest insect order where has not been studied yet. generated ten head RNA-Seq libraries with DNA-Seq from matched individuals. Results identified thousands high-confidence sites C. . Overrepresentation nonsynonymous was observed, but conserved recoding across different orders very rare. Under cold stress, global efficiency down-regulated general transcriptional processes were shut down. Nevertheless, we found an interesting site “conserved non-conserved recoding” potassium channel Shab which significantly up-regulated cold, serving as candidate functional response temperature stress. Conclusions largely recodes proteome. first editome Hemiptera indicates independent origin beneficial during evolution, advances our conservation, editing.

Untangling the patterns and drivers behind diversification extinction of highly diversified lineages remains a challenge in evolutionary biology. While insect has been widely studied through "Big Four" orders (Coleoptera, Hymenoptera, Lepidoptera Diptera), fifth most diverse order, Hemiptera, often overlooked. Hemiptera exhibit rich fossil record are present-day ecosystems, with many closely associated to their host plants, making them crucial group for studying how past ecological shifts-such as mass extinctions floral turnovers-have influenced diversification. This study leverages birth-death models Bayesian framework estimate diversity dynamics. Our results reveal that global changes flora over time significantly shaped trajectories Hemiptera. Two major faunal turnovers particularly diversification: (i) aftermath Permo-Triassic (ii) Angiosperm Terrestrial Revolution. analyses suggest clades was driven by floristic shifts combined competitive pressures from overlapping niches. Leveraging extensive allowed us refine our understanding across hemipteran lineages.

Abstract Plant-sucking insects have intricate associations with a diverse array of microorganisms to facilitate their adaptation specific ecological niches. The midgut phytophagous true bugs is generally structured into four distinct compartments accommodate microbiota. Nevertheless, there limited understanding regarding the origins these gut microbiomes, mechanisms behind microbial community assembly, and interactions between microbiomes insect hosts. In this study, we conducted comprehensive survey communities within bean bug Riptortus pedestris , soybean plant, bulk soil across 12 geographical fields in China, utilizing high-throughput sequencing 16 S rRNA gene. Our findings illuminated that microbiota plant-sucking predominantly originated from surrounding environment, plants also play subordinate role mediating acquisition for insects. Furthermore, our investigation suggested composition microbiome was probably shaped by host selection and/or microbe-microbe at compartment level, marginal influence factors. Additionally, had unveiled noteworthy dynamic core bacterial taxa, particularly Burkholderia which were initially sourced environment subsequently enriched compartments. This enrichment played significant enhancing reproduction. These contribute evolving insect-plant-soil ecosystem, shedding additional light on underpin significance partnerships adaptation.

Adenosine-to-inosine (A-to-I) RNA editing, mediated by metazoan ADAR enzymes, is a prevalent post-transcriptional modification that diversifies the proteome and promotes adaptive evolution of organisms. The Drosophila Adar gene has an auto-recoding site (termed S>G site) forms negative-feedback loop stabilizes global editing activity. However, evolutionary trajectory in many other insects remains largely unknown, preventing us from deeper understanding on significance this auto-editing mechanism. In study, we retrieved well-annotated genomes 375 arthropod species including five major insect orders (Lepidoptera, Diptera, Coleoptera, Hymenoptera Hemiptera) several outgroup species. We performed comparative genomic analysis site. found ancestral state was uneditable serine codon (unSer) maintained Hymenoptera. editable (edSer) appeared common ancestor Lepidoptera, Diptera Coleoptera almost fixed three orders. Interestingly, Hemiptera possessed comparable numbers unSer edSer codons, few 'intermediate codons', demonstrating multi-step trace unSer-to-edSer with non-synchronized mutations at positions. argue best evidence supporting 'proteomic diversifying hypothesis' editing. Our work deepens our which activity controls transcriptomic diversity.

Abstract Representatives of the subfamily Cylapinae (Insecta: Heteroptera: Miridae) mostly inhabit subtropics and tropics. The group currently comprises five tribes: Bothriomirini, Cylapini, Fulviini, Rhinomirini, Vanniini. Additionally, Psallopinae are sometimes included in this as a tribe. interrelationships within unknown, monophyly is doubtful, phylogenetic study focusing on entire has never been published. molecular fossil data analyses show that Miridae occurred at least Jurassic. divergence dates for Cyalpinae tribes unknown. We performed analysis based morphological data, addition to combined dataset. calibrated trees with data. results suggested non-monophyly Cylapinae. Bothriomirini was confirmed. Cylapini were rendered non-monophyletic. Cylapus complex formed clade Vanniini, Vanniini doubtful. Fulviini recovered non-monophyletic, representatives fell into two separate well-supported clades. Dating showed groups suprageneric level distributed across different continents diverged near boarder between Mesosoic Cenosoic, also true Asian South American complex. Australian genera Cenozoic.

The phytophagous Halyomorpha halys (Hemiptera: Pentatomidae) is a global agricultural pest that damages many crops. Conversely, the predatory Arma chinensis shows promise as biological control agent against lepidopteran and coleopteran pests. A. are closely related species with different feeding habits, confirmed via genomic morphological analyses. However, no study investigating implications of these differences has been reported. Herein, 16S rRNA sequencing technology was employed to analyze microbiota diversity function in tissues (salivary glands, gut, sperm, ovaries) H. elucidate from microbial perspective. Additionally, adult male-to-female ratio organs statistically similar, while not. Based on dominance symbionts two bug species, we inferred Sodalis involved reproduction digestion chinensis, Spiroplasma Pantoea play essential roles digestion. We analyzed data laying foundation for further understanding symbiosis halys, which may inform development strategies.

Abstract Urostylididae, a phytophagous heteropteran family that feeds on the sap of various trees and shrubs, comprises 8 genera 173 species. Its phylogeny has received little attention, no studies have revealed its generic monophyly or relationships. We present first molecular Urostylididae based complete mitogenomes nuclear ribosomal genes from almost all representative species, using maximum likelihood analysis Bayesian inference. All phylogenetic results showed overall consistent topological relationships, indicating polyphyly three most speciose genera, Urolabida , Urochela Urostylis . Among monotypic Chelurotropella formed stable relationship with wui in trees, Cobbenicoris was sister group fici but position variation among Urochellus cuneata species two more different trees. The smaller genus Tessaromerus always to tricarinata their positions varied Thus, currently recognized are unreliable. Furthermore, our suggested some incongruence produced analytical methods data sets, mainly deep internal nodes, short branches low support values. Given quartet‐based evaluation system branch patterns, underwent rapid radiation resulting incomplete lineage sorting introgression making analyses sensitive method used. Moreover, might caused morphological homoplasy diagnostic characters leading taxonomic confusion for Urostylididae. Therefore, thorough revision this is needed.

The majority of non-native animal species globally are insects, though some insect more successful invaders than others. These differences can be attributed, in part, to among dominant trophic groups. Previous analyses indicate that herbivores generally over-represented while other groups, such as predators, under-represented. Here we explore how invasion success varies taxa and We quantify over-representation grouped by taxon (order or family) larval group (herbivore, detritivore, predator, parasite, brood carer); over- under-representation is computed comparing proportional representation groups 12 world regions with total numbers these same globally. Although the most non-natives, found their vary taxonomic groups: Hemiptera, Diptera, Thysanoptera Hymenoptera, but under-represented Lepidoptera Orthoptera; similar patterns seen at family-level within orders. Even after accounting for group, orders were still over-represented. Within this pattern appeared strongest herbivores, where predominantly parthenogenetic families belonging Hemiptera assemblages, Polyneoptera Over time (1850s 2000s), fractions certain have varied, parasites, a considerable turnover took place from mostly bird-lice (Psocodea) 19 th century parasitic wasps (Hymenoptera) 20 century. It thus likely factors associations pathways (e.g., plants, wood packaging), cause observed different
