First record of mitochondrial genome of Teredorus nigropennis (Orthoptera: Tetrigidae) and phylogenetic analysis

Mitochondrial DNA. Part B. Resources, 2020
The nearly complete mitochondrial genome (mitogenome) of Teredorus nigropennis was determined and analyzed. This mitogenome was 14,652 bp in size and encoded 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes.

Social media highlights the overlooked impact of cats on arthropods

Insect Conservation and Diversity, EarlyView.
The impact of domestic cats on vertebrate biodiversity is unequivocal; however, we still know little about their effects on arthropods. By analysing over 17,000 photos and videos from social media platforms (iStock and TikTok), we documented 550 predation events of cats on arthropods.

Arthropod niche differentiation linked to grazing‐induced sward islets in intensively managed agricultural pasture

Insect Conservation and Diversity, EarlyView.
In a given number of samples, grassland sward islets contain more species of arthropods than the surrounding sward. When corrected for abundance, there is no difference in species richness, suggesting that the effect of islets might purely be to concentrate arthropods. The community structure differences indicated by non‐metric multidimensional scaling

Requirement of group I lytic polysaccharide monooxygenase for turnover of chitinous cuticle during moulting in two forest pest beetles, Monochamus alternatus and Psacothea hilaris

Insect Molecular Biology, EarlyView.
Group I LPMO15‐1 cDNAs from two economically important forest insect pests, M. alternatus and P. hilaris, were cloned. MaLPMO15‐1 and PhLPMO15‐1 show a similar pattern of expression during late stages of development. RNAi for LPMO15‐1 causes failure of adult eclosion in both M. alternatus and P. hilaris.

Does Karyotype Structure Co‐Occurrence Patterns in a Chromosomally Diverse and Species‐Rich Clade of Lizards (Genus Sceloporus)?

Journal of Biogeography, EarlyView.
ABSTRACT Aim We investigated the biogeographic consequences of chromosomal speciation, or structural changes in chromosome arrangement that lead to reproductive isolation, an intriguing speciation mechanism with implications for the phylogenetic and geographic distribution of species and chromosomal diversity. Location. North and Central America. Taxa.

Ecology and abundance of a relict population of the bush cricket Saga pedo in the Northern Apennines, Italy

Ecology and Evolution
The expansion of forest cover and intensification of agriculture represent the main threats to the bush cricket Saga pedo, currently listed as Vulnerable globally by the IUCN and included in Annex IV of the European Union Habitats Directive.

Determining Terminal Velocities of Selected Insects and Substitute Materials to Develop Future Test Procedures for Insect‐Friendly Mowing Technology

Journal of Applied Entomology, EarlyView.
ABSTRACT Agricultural grasslands are vital habitats for insects that provide key ecosystem services. However, conventional rotary mowers are proposed to cause significant insect mortality due to the high rotational speed of their blades and the resulting airflow.

Development of a non‐lethal stomach content analysis method for freshwater eels: An empirical evaluation of the tube method for Anguilla marmorata

Journal of Fish Biology, EarlyView.
Abstract Understanding the feeding habits of predatory fish is essential for unravelling food web structures and implementing conservation strategies in riverine ecosystems. However, conventional lethal stomach content analysis methods are not necessarily appropriate for long‐term dietary studies, particularly for threatened species, as they require ...

Nutrient landscape of a cricket nymph: How dietary protein and carbohydrate shape intake, performance, and body composition in the two‐spotted cricket, Gryllus bimaculatus

Physiological Entomology, EarlyView.
Survival of Gryllus bimaculatus nymphs was highest on protein‐biased diets (P:C = 3.86:1), whereas growth and body mass were maximized on slightly carbohydrate‐biased diets (P:C = 1:1.47). Maximum body protein and lipid contents were attained at P:C ratios of 1.14:1 and 1:5.56, respectively. When given a food choice, G. bimaculatus nymphs self‐selected

Revision of the Poecilimon ornatus group (Orthoptera: Phaneropteridae) with particular reference to the taxa in Bulgaria and Macedonia

European Journal of Entomology, 2010
The Poecilimon ornatus group has an exclusively European distribution and includes the largest species in the genus. A revision of the taxa belonging to this group in Bulgaria and Macedonia (Central and Eastern Balkan Peninsula) is presented.
