European Journal of Entomology, 2011 The present study focused on the evolution of the karyotype in 21 taxa of the genus Isophya, which was done by mapping the location on the chromosomes of ribosomal RNA (rRNA) coding genes using fluorescence in situ hybridization (FISH) with an 18S rDNA ...

Assessing the Impact of Urbanization on Grasshopper Behaviour—A Fieldwork Approach
Journal of Applied Entomology, EarlyView.ABSTRACT Urbanization is one of the most significant land‐use changes globally, profoundly impacting biodiversity across taxa. Insects, including grasshoppers (Orthoptera), are particularly sensitive to urban pressures, often exhibiting both morphological and behavioural adaptations.

Sex- and season-dependent behaviour in a flightless insect, the Auckland tree weta (Hemideina thoracica) [PDF]
, 2013 In a polygynous mating system, males frequently compete by locating and defending sites with resources essential to female survival and reproduction. We investigated seasonal changes in site occupancy in a sexually dimorphic, harem-forming insect, the ...

Importance of Morphological Features in Orthoptera Identification [PDF]
, 2020 This article analyzes the problems of implementing image recognition methods and algorithms for identifying biological objects. The Orthoptera group was chosen as a biological object. Orthoptera is a taxonomic order of insects that includes grasshoppers,

Journal of Systematics and Evolution, EarlyView.Our ancestral state reconstruction in tree crickets reveals multiple independent and irreversible losses of sound‐producing and ‐receiving structures, supporting the convergent evolution of the silent phenotype. We demonstrate strong evolutionary integration between forewings and tympana, although the discovery of ‘silent listeners′ and ‘deaf singers ...

Sound signalling in orthoptera [PDF]
, 2002 The sounds produced by orthopteran insects are very diverse. They are widely studied for the insight they give into acoustic behaviour and the biophysical aspects of sound production and hearing, as well as the transduction of sound to neural signals in the ear and the subsequent processing of information in the central nervous system.

Defecation in preparation for ecdysis drives microplastic clearance in cricket nymphs
Physiological Entomology, EarlyView.In preparation for ecdysis, cricket nymphs cease feeding and gradually clear their gut contents via frass production, which removes most ingested MPs from their digestive tract. Following exoskeletal moulting, the foregut lining, including any remaining MPs, is shed and excreted alongside frass approximately 6 h later.

Molecular Ecology Resources, Volume 26, Issue 7, October 2026.ABSTRACT With the massive increase in genomic resources, it is becoming increasingly popular to analyse thousands of loci across many species. However, many of the available genomes are not annotated, which hinders an efficient search for orthologous protein‐coding genes.
