DNA barcodes for Nearctic Auchenorrhyncha (Insecta: Hemiptera). [PDF]

PLoS ONE, 2014
BACKGROUND:Many studies have shown the suitability of sequence variation in the 5' region of the mitochondrial cytochrome c oxidase I (COI) gene as a DNA barcode for the identification of species in a wide range of animal groups.

The Endosymbiont Consortia of Two Cixiidae Planthoppers Reveal an Ancient Symbiosis With 'Candidatus Mirabilia Symbiotica'. [PDF]

Environ Microbiol Rep
Many insects harbour ancient beneficial endosymbionts that produce essential nutrients. Two planthopper species from the Cixiidae family harbour different tripartite endosymbiont consortia, including a previously unknown and likely ancient Gammaproteobacterium in addition to Karelsulcia and Vidania.

Phylogenomics Resolves the Evolution of Sternorrhyncha (Insecta: Hemiptera). [PDF]

Ecol Evol
Phylogeny of Sternorrhyncha based on Matrix2 under PMSF (LG+C60+F+R) model. ABSTRACT Sternorrhyncha, one of the four major suborders of Hemiptera, represents a phytophagous insect clade comprising nearly 18,000 described species. While recent phylogenomic studies have made significant efforts to elucidate the internal phylogenetic relationships within ...

Are Findings of Key Insect Metrics Generalizable Across Different Taxa in Malaise Trap Samples? [PDF]

Ecol Evol
Malaise traps are increasingly used for global insect monitoring. However, it remains unclear whether patterns in total insect biomass from these traps reflect only changes in dominant taxa, or whether they reflect changes in other key community metrics and taxonomic groups.

The loss of the urea cycle and ornithine metabolism in different insect orders: An omics approach. [PDF]

Insect Mol Biol
Among urea cycle enzymes, only the nitric oxide synthase gene is universally present across insect genomes. All Hemiptera species lack the enzymes needed to convert citrulline to arginine, and some also lack the pathway from arginine to ornithine. Putrescine and spermidine synthesis is conserved in all insects, but aphids lack the capability to produce

Primary and Secondary Symbionts of Cambodian Cicadellidae and the Role of Parasitisation. [PDF]

Environ Microbiol Rep
Leafhoppers are key agricultural pests, and their interactions with parasitoids may be influenced by microbial symbionts. In this study, we characterized the bacterial communities of six Cambodian leafhopper species and their parasitoids, finding that while Sulcia dominates leafhopper microbiotas, parasitoids exhibit higher microbial diversity.

A dichotomous key and checklist for Mexican Athysanini leafhopper genera (Hemiptera: Cicadellidae) with a new species from the Oaxacan dry tropical forest

European Journal of Entomology, 2021
Most Neotropical forest-dwelling leafhopper species are rare and exhibit limited distributions. The Mexican leafhopper fauna is known to be highly diverse and identification of genera and species is difficult because no attempts have been made to provide

Effects of the timing of grazing on insect diversity and insect-plant interactions in mountain grasslands. [PDF]

Ecol Appl
Abstract Grazing is the common agricultural land‐use in mountain regions. It is of high socioeconomic importance but also essential for conservation as extensive mountain pastures are hotspots of biodiversity. Climate change is causing earlier growing seasons, prompting earlier livestock turnout.

Erhebung von Zikaden (Hemiptera: Auchenorrhyncha) in Kräuteranbauflächen Südtirols

Julius-Kühn-Archiv, 2023
Im Kräuteranbau kommen verschiedene Arten von Zikaden (Auchenorrhyncha) vor, die als Pflanzensaftsauger, vor allem an Lamiaceaen, Schäden verursachen. Da es in Südtirol noch keine Daten über die Zikadenfauna im Arznei-und Gewürzpflanzenanbau gibt, wurde ...
