National Trade can Drive Range Expansion of Bark- and Wood-Boring Beetles

Journal of Economic Entomology, Journal Year: 2017, Volume and Issue: 111(1), P. 260 - 268

Published: Oct. 19, 2017

Several native species of bark- and wood-boring beetles (Coleoptera) have expanded their range within biogeographic regions in the last years, but role human activity driving this phenomenon has been underinvestigated. Here we analyze 3 yr trapping records (Cerambycidae Scolytinae) collected at 12 Italian ports surrounding forests to help elucidate movement region. We trapped several that occurred either inside or outside distributional Italy. Species richness abundance those found located were most strongly associated with amount forest cover landscape, suggesting they could arrived from nearby forests. The was instead linked national imports arriving port where occurred, likely introduced other parts This study demonstrates sea transportation can favor expansion a country, confirms surround serve as source be potentially moved exports.

DNA barcoding of pear psyllids (Hemiptera: Psylloidea: Psyllidae), a tale of continued misidentifications

Bulletin of Entomological Research, Journal Year: 2020, Volume and Issue: 110(4), P. 521 - 534

Abstract Pear psyllids (Hemiptera: Psylloidea: Psyllidae: Cacopsylla spp.) belong to the most serious pests of pear ( Pyrus spp.). They damage trees by excessive removal phloem sap, soiling fruits with honeydew which, in turn, provides a substrate for sooty mould, and transmission Candidatus Phytoplasma spp., causal agents decline disease. The morphological similarity, presence seasonal dimorphism that affects adult colour, size wing morphology uncritical use species names, led much confusion taxonomy psyllids. As result, have been frequently misidentified. Many entries attributed pyricola other GenBank are misidentifications which additional, unnecessary confusion. Here we analysed DNA barcodes 11 psyllid from eastern Asia, Europe Iran using four mitochondrial gene fragments (COI 658 bp, COI 403 COI-tRNA leu -COII 580 bp 16S rDNA 452 bp). efficiency identification was notably high considerable barcoding gaps were observed all markers.

Genome‐scale phylogeography resolves the native population structure of the Asian longhorned beetle, Anoplophora glabripennis (Motschulsky)

Evolutionary Applications, Journal Year: 2022, Volume and Issue: 15(6), P. 934 - 953

Published: April 11, 2022

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, Journal Year: 2024, Volume and Issue: 202(3)

Published: Feb. 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.

Identification of the Red-Necked Longhorn Beetle Aromia bungii (Faldermann, 1835) (Coleoptera: Cerambycidae) with Real-Time PCR on Frass

Sustainability, Journal Year: 2020, Volume and Issue: 12(15), P. 6041 - 6041

Published: July 28, 2020

Aromia bungii (Faldermann, 1835) (Coleoptera: Cerambycidae), the red-necked longhorn beetle is native to eastern Asia, where it an important wood-borer of fruit and ornamental species genus Prunus. A. a quarantine pest in European Union, following its accidental introduction establishment Germany Italy, currently included list priority pests. To confirm infestations outbreak areas, adult or larval specimens are needed perform morphological molecular analyses. The presence larvae inside attacked trees makes collection particularly difficult. Thus, we present two diagnostic protocols based on frass analysis with real-time PCR (probe SYBR Green). results obtained show that non-invasive approach for detecting this harmful invasive can be reliable accurate alternative tool phytosanitary surveys, as well outline sustainable management strategy.
