The early evolutionary history of neo-sex chromosomes in Neotropical grasshoppers, Boliviacris noroestensis (Orthoptera: Acrididae: Melanoplinae) [PDF]

open access: yesEuropean Journal of Entomology, 2014
Neo-sex chromosomes are an important component of chromosome variation in Orthoptera, particularly South American Melanoplinae species, which have proven to be outstanding experimental model system to study the mechanism of sex chromosome evolution in ...

Phenotypic pattern over centric fusion clinal variation in the water-hyacinth grasshopper, Cornops aquaticum (Orthoptera: Acrididae) [PDF]

open access: yesEuropean Journal of Entomology, 2018
The water-hyacinth grasshopper, Cornops aquaticum, occurs in freshwater environments in the New World between latitudes 23°N and 35°S. At the southernmost margin of this distribution the populations are polymorphic for three centric fusions (Robertsonian

New records of exotic crickets in Europe: Homoeogryllus species (Orthoptera: Gryllidea: Phalangopsidae) [PDF]

open access: yesJournal of Orthoptera Research, 2020
This short note lists new records of exotic crickets belonging to the genus Homoeogryllus (Orthoptera: Gryllidea: Phalangopsidae) in Europe (Poland and Belgium) and discusses the most probable scenarios of their arrival from tropical regions. Photographs

Distribution Patterns of Grasshoppers and Their Kin over the Eurasian Steppes

open access: yesInsects, 2021
The main aims of this paper are to reveal general patterns of Orthoptera distribution in the Eurasian steppes, to evaluate long-term trends of changes in distribution of taxa and populations, and to estimate the potential for population changes relative ...

The response of Orthoptera to grazing on flood defense embankments in Europe [PDF]

open access: yesJournal of Orthoptera Research, 2018
European flood defense embankments form an excellent habitat for Orthoptera. To be effective against storms, these vegetated earth embankments have to be managed by grazing or mowing.

Notes on feeding, locomotor activity rhythms and orientation in the pygmy mole cricket Afrotridactylus cf. usambaricus in Kenya (Orthoptera: Tridactyloidea)

open access: yesEuropean Journal of Entomology, 2021
Immature individuals of Afrotridactylus cf. usambaricus (Sjöstedt, 1910) were recorded on a marine sandy beach probably feeding on bacteria, microalgae and mesopsammic organisms.

MtOrt: an empirical mitochondrial amino acid substitution model for evolutionary studies of Orthoptera insects

open access: yesBMC Evolutionary Biology, 2020
Background Amino acid substitution models play an important role in inferring phylogenies from proteins. Although different amino acid substitution models have been proposed, only a few were estimated from mitochondrial protein sequences for specific ...

Fauna and landscape-zonal distribution of Orthoptera in the Komi Republic (Russia) [PDF]

open access: yesКавказский энтомологический бюллетень, 2020
Orthoptera is a promising model group of insects for large-scale zoogeographic studies. The Komi Republic (Russia, West Siberia) is a suitable region for such kind of work, because it has meridional orientation, coinciding with the global trend of ...

Diversity of mariner-like elements in Orthoptera

open access: yesВавиловский журнал генетики и селекции, 2020
Mariner-like elements (MLEs) are among the most widespread DNA transposable elements in eukaryotes. Insects were the first organisms in which MLEs were identified, however the diversity of MLEs in the insect order Orthoptera has not yet been addressed ...
