Human-assisted movement has allowed the Asian longhorned beetle (ALB, Anoplophora glabripennis (Motschulsky)) to spread beyond its native range and become a globally regulated invasive pest. Within of China Korean peninsula, human-mediated dispersal also caused cryptic translocation insects, resulting in population structure complexity. Previous studies used genetic methods detangle this complexity but were unable clearly delimit populations which is needed develop downstream biosurveillance tools. We genome-wide markers define historical ALB contemporary between regions. genotyping-by-sequencing generate 6102 single-nucleotide polymorphisms (SNPs) amplicon sequencing genotype 53 microsatellites. In total, we genotyped 712 individuals from ALB's distribution. observed six distinct clusters among populations, with clear delineation northern southern groups. Most South Korea China. Our results indicate divergence suggest limited large-scale admixture, did identify restricted number cases identified SNPs under selection describe clinal allele frequency pattern missense variant associated glycerol kinase, an important enzyme utilization insect cryoprotectant. further demonstrate that small numbers can assign geographic regions high probability, paving way for novel

Molecular identification of immature Cerambycinae (Coleoptera: Cerambycidae): revisiting the significance of immature morphologies

Zoological Journal of the Linnean Society, Год журнала: 2024, Номер 202(3)

Опубликована: Фев. 2, 2024

Abstract The microstructure of immature insect forms plays a crucial role in systematics, especially inferring phylogenetic relationships and designating the morphological basis for taxonomic units. However, longhorn beetle larvae pupae is poorly understood, owing to difficulties obtaining them technical limitations. Among 90 80 collected photographed, 31 15 remained unidentified after bionomical evidence-based identification. Cytochrome c oxidase I sequences were amplified successfully from 68 59 pupae. Molecular identification using tree-based analysis identified 28 undetermined (90.3%) 14 (93.3%) species level. We highlight usefulness DNA barcoding identifying cerambycid beetles filling gaps public databases. This study also demonstrates how can clarify polyphyletic taxa on phylogeny emphasizes significance stages systematics.

Validating a variable-instar, climate-based phenology model for the Asian longhorned beetle (Coleoptera: Cerambycidae) using field data from South Carolina

Abstract The Asian longhorned beetle, Anoplophora glabripennis (ALB, Coleoptera: Cerambycidae), is a federally regulated invasive species capable of infesting several different genera hardwood trees. Accurate knowledge ALB’s phenology critical for the effective implementation management and eradication plans. We updated ALBLT prediction model used empirical data collected in South Carolina, USA to validate v. 2.0. new largely agreed with ALB life stages found field collections, except late instars pupae. also ran at 8 other potentially high-risk cities contiguous United States latitudes ranging from 28°N (Tampa, FL) 41°N (Chicago, IL) predict how long single generation might take develop these environments. Model predictions ranged 2–3-yr lifecycle Chicago potential cycle < 1 yr Tampa. These can help inform managers specialists should be environments, aid developing an adequate plan.

Shape as a Key to Taxonomy: Morphometric Analysis of Tetropium Species (Coleoptera: Cerambycidae)

Insects, Год журнала: 2025, Номер 16(4), С. 386 - 386

Опубликована: Апрель 4, 2025

The study of shape by the use geometric morphometrics has been an important tool for addressing taxonomic challenges in complex groups like genus Tetropium Kirby, 1837 (Coleoptera, Cerambycidae). This insect includes 28 species, 8 which are found North America, with invasive T. fuscum (Fabricius) posing a significant quarantine risk as pest coniferous trees. present evaluated to analyze pronotum females nine species genus, showing effectiveness this distinguishing between species. Even if some overlaps were research highlights potential GM developing monitoring, managements, and integrated management programs. Our findings suggest that comprehensive database landmarks, encompassing broader geographic ecological diversity, could further improve identification at ports entry facilitate trade.
