The Effects of Diet on the Expression of Male Dimorphic Colouration and Weaponry in a Species of Neotropical Katydid. [PDF]

Ecol Evol
Male alternative reproductive tactics are widespread, often involving distinct morphs influenced by genetics or the environment. This study confirms two male morphs in the bush cricket Satizabalus jorgevargasi—larger, more colourful majors and smaller, duller minors—and tests how diet affects their development.

Evolutionary history and divergence times of Tettigoniidae (Orthoptera) inferred from mitochondrial phylogenomics [PDF]

Frontiers in Genetics
BackgroundAdvances in high-throughput sequencing technology have led to a rapid increase in the number of sequenced mitochondrial genomes (mitogenomes), ensuring the emergence of mitochondrial phylogenomics, as a powerful tool for understanding the ...

Replicated Differential Expression Analysis in a Green-Brown Polymorphic Grasshopper Reveals Role of Beta-Carotene-Binding Protein in Body Coloration. [PDF]

Mol Ecol
ABSTRACT Orthoptera provide a well‐documented case of transspecies colour polymorphism, with green and brown morphs coexisting in many species. This colour polymorphism is likely under long‐term balancing selection, but the genetic and molecular mechanisms underlying the variation remain poorly understood.

Evolutionary Dynamics of Satellite DNA Repeats across the Tettigoniidae Family: Insights from Genomic Analysis [PDF]

Biomolecules
Satellite DNA repeats are repetitive DNA sequences found in eukaryotic genomes, typically consisting of short DNA motifs repeated in tandem arrays. Despite the vast body of literature on satellite DNA repeats in other taxa, investigations specifically ...

Identifying Key Biodiversity Areas Based on Distinct Genetic Diversity. [PDF]

Mol Ecol Resour
ABSTRACT Key Biodiversity Areas (KBAs) are sites that contribute significantly to the global persistence of biodiversity. Distinct genetic diversity has been introduced as one of the metrics to estimate whether a site holds a threshold proportion of a species' global genetic diversity during the KBA identification process.

Different steps in the evolution of neo-sex chromosomes in two East African Spalacomimus species (Orthoptera: Tettigoniidae: Hetrodinae)

European Journal of Entomology, 2015
Two orthopteran species belonging to the East African genus Spalacomimus, S. verruciferus and S. talpa (Tettigoniidae: Hetrodinae), were investigated using both molecular cytogenetic techniques, including fluorescence in situ hybridization with 18S rDNA ...

Lack of correlation between vertical distribution and carrier frequency, and preference for open spaces in arboreal katydids that use extreme ultrasound, in Gorgona, Colombia (Orthoptera: Tettigoniidae) [PDF]

Revista de Biología Tropical, 2014
Los machos de Tettigoniidae producen sonido frotando las alas anteriores para atraer a sus hembras coespecíficas con fines reproductivos (mecanismo conocido como estridulación).

Two new host records for Centrodora italica Ferrière (Hymenoptera, Aphelinidae) from eggs of Tettigoniidae (Orthoptera, Ensifera) in northeastern Italy [PDF]

ZooKeys, 2023
The egg parasitoid Centrodora italica Ferrière is reported for the first time from sentinel eggs of two species of Tettigoniidae (Orthoptera), Pachytrachis gracilis (Brunner von Wattenwyl) and Eupholidoptera schmidti (Fieber). In Italy, only two hosts of

Experimental evidence for density-determined wing dimorphism in two bush-crickets (Ensifera: Tettigoniidae)

European Journal of Entomology, 2009
Macroptery is common in many species of Orthoptera, but the causes are still discussed. Besides the assumption that macroptery is genetically determined, there is evidence that wing dimorphism is induced by environmental factors, particularly population ...
