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 and interesting Orthoptera from the Arabian Peninsula and Socotra [PDF]

open access: yesZooKeys, 2017
This paper reports on some interesting taxa recently found in the Arabian Peninsula and the island of Socotra. Among them is a new species of brachypterous grasshopper Sphodromerus carapezzanus sp. n.

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 ...

The central-marginal hypothesis in acridid Orthoptera: A critique of Colombo's (2012) article [PDF]

open access: yesEuropean Journal of Entomology, 2013
We discuss and criticise the contention of Colombo (2012) that the central-marginal model does not apply to three species of chromosomally polymorphic acridid grasshoppers, and that chromosomal clines in these species are a consequence of temperature ...

Drivers of insect herbivory resistance and tolerance to plant damage in the Brachypodium distachyon species complex. [PDF]

open access: yesAm J Bot
Abstract Premise Insect herbivory is a major biotic factor shaping plant populations and driving the evolution of defensive traits. Polyploidy (whole‐genome duplication) often induces substantial phenotypic and genotypic changes that may affect species interactions, including herbivory.

Fungal-Based Biopesticide Formulations to Control Nymphs and Adults of the Desert Locust, Schistocerca gregaria Forskål (Orthoptera: Acrididae): A Laboratory and Field Cage Study

open access: yesAgronomy, 2022
This is the first field study in which we have tested the efficacy of four different entomopathogenic fungal (EPF) formulations together in single study—i.e., Green Muscle, Green Guard, Metarhizium anisopliae, and an isolate of Beauveria bassiana ...

Transcriptomic data reveals nuclear-mitochondrial discordance in Gomphocerinae grasshoppers (Insecta: Orthoptera: Acrididae).

open access: yesMolecular Phylogenetics and Evolution, 2022
The phylogeny of many groups of Orthoptera remains poorly understood. Previous phylogenetic studies largely restricted to few mitochondrial markers found many species in the grasshopper subfamily Gomphocerinae to be para- or polyphyletic, presumably ...

Evolution of chromosome number in grasshoppers (Orthoptera: Caelifera: Acrididae)

open access: yesOrganisms Diversity & Evolution, 2022
Orthoptera have some of the largest genomes of all insects. At the same time, the architecture of their genomes remains poorly understood. Comparative cytological data across a wide range of taxa, even for basic parameters such as chromosome number, may ...
