In 2014-2019, we conducted six experiments in north-central Georgia an attempt to verify the aggregation pheromone response of ambrosia beetle Gnathotrichus materiarius (Fitch) (Coleoptera: Curculionidae: Scolytinae: Scolytini: Corthylina) sulcatol known be produced by male G. materiarius; failed catch any materiarius. However, did find that another corthyline species Monarthrum mali was attracted (R)-(-)-sulcatol, whereas longhorn Leptostylus asperatus (Haldeman) Cerambycidae: Lamiinae) (S)-(+)-sulcatol.

Full taxonomic characterisation of fungal communities is necessary for establishing ecological associations and early detection pathogens invasive species. Complex fungi are regularly characterised by metabarcoding using the Internal Transcribed Spacer (ITS) Large-Subunit (LSU) gene rRNA locus, but reliance on a single short sequence fragment limits confidence identification. Here we link from ITS2 LSU D1-D2 regions to characterise associated with bark beetles (Scolytinae), likely vectors several tree pathogens. Both markers revealed similar patterns overall species richness response key variables (beetle species, forest type), identification against respective reference databases various classifiers poor resolution towards lower levels, especially level. Thus, Operational Taxonomic Units (OTUs) could not be linked via across ITS fragments. However, phylogenetic trees (focused epidemiologically important Sordariomycetes) placed OTUs obtained either marker relative sequences entire cistron that includes both loci demonstrated largely distribution LSU-derived OTUs. Sensitivity analysis congruence in suggested biologically most defensible threshold values OTU delimitation Sordariomycetes 98% 99% D1-D2. Studies canonical barcode require corroboration additional loci. Phylogenetic aligned full shows higher success rate greater accuracy compared probabilistic classifiers.

Abstract Molecular assays based on qPCR TaqMan Probes were developed to identify three species of the genus Xylosandrus , X. compactus, crassiusculus and germanus (Coleoptera Curculionidae Scolytinae). These ambrosia beetles are xylophagous alien Europe, causing damages many ornamental fruiting trees as well shrubs. DNA extraction was carried out from adults, larvae biological samples derived insect infested plants. For compactus segments galleries in thin twigs cut processed; case raw frass extruded exit holes used, while extracted small wood chips removed around holes. The inclusive for target exclusive all non-target tested. LoD 3.2 pg/µL 0.016 ng/µL woody matrices other two species. Both repeatability reproducibility estimated adults samples, showing very low values ranging between 0.00 4.11. Thus, proposed diagnostic resulted be efficient also used extraction, demonstrating applicability protocol absence dead specimens or living stages.

Identifying alien species is important to ensure the early detection of biological invasions and survey shifts in distributions context global change. Here, we report on three bark ambrosia beetles newly detected Switzerland: Cyclorhipidion distinguendum (Eggers, 1930), C. pelliculosum (Eichhoff, 1878), Hypothenemus eruditus (Westwood, 1834). These were recorded for first time during a comprehensive saproxylic accross major forest types along an altitudinal gradient entire growing season southern Alps, canton Ticino. Their local abundance number occurrences different lowland habitats, including alluvial forests national importance, indicates that all are already naturalized. Given their polyphagy, it likely will become more extensively distributed across Switzerland, with yet unknown environmental impact.

Many bark beetles of the subfamily Scolytinae are most economically important insect pests coniferous forests worldwide. In this study, we sequenced mitochondrial genomes eight beetle species, including Dendroctonus micans, Orthotomicus erosus, Polygraphus poligraphus, Dryocoetes hectographus, Ips nitidus, typographus, subelongatus, and hauseri, to examine their structural characteristics determine phylogenetic relationships. We also used previously published genome sequence data from other species identify localize studied within phylogeny. Their gene arrangement matched presumed ancestral pattern these beetles. Start stop codon usage, amino acid abundance, relative usage frequencies were conserved among Genetic distances between ranged 0.037 0.418, evolutionary rates protein-coding genes 0.07 for COI 0.69 ND2.
