Effect of temperature and species of plant on the consumption of leaves by three species of Orthoptera under laboratory conditions

open access: yesEuropean Journal of Entomology, 2013
In the Mediterranean area the orthopterans Calliptamus barbarus barbarus, Dociostaurus maroccanus and Tettigonia viridissima are considered to be pests of major economic importance crop plants.

Spatial prediction of Melanoplus differentialis using an ensemble of multiple species distribution models

open access: yesInsect Conservation and Diversity, EarlyView.
Ensemble model using multiple niche models was constructed to globally identify regions at high risk for Melanoplus differentialis distribution under climate change. The occurrence possibility was found to be particularly high in its native region, the United States, and high invasion risk was identified in non‐native regions, particularly in Europe ...

The development of insect diversity and ecosystem complexity on green roofs: A review

open access: yesInsect Conservation and Diversity, EarlyView.
A classification system of different roof types is presented to improve consistency in green roof research. Landscape and green roof characteristics influence ecosystem development, but can be further explained by ecological concepts, like neutral and niche theory.

Chromosome fusion polymorphisms in the grasshopper, Dichroplus fuscus (Orthoptera: Acrididae: Melanoplinae): Insights on meiotic effects

open access: yesEuropean Journal of Entomology, 2015
Robertsonian fusions account for many of the changes in the evolution of the orthopteran karyotype; in their origin, a centric fusion is involved between two acro-telocentric chromosomes, forming a single bi-armed chromosome.

Spreading of recently introduced North American sand dropseed (Sporobolus cryptandrus) threatens European native dry grassland arthropods

open access: yesInsect Conservation and Diversity, EarlyView.
The effects of sand dropseed (Sporobolus cryptandrus) invasion on arthropods depended on its density and varied between habitat types and arthropod groups. Vegetation‐dwelling, primarily herbivorous orthopterans and true bugs were most sensitive to invasion. Sand dropseed negatively affected the arthropod species of high natural value.

The occurrence in the migratory locust, Locusta migratoria (Orthoptera: Acrididae), of a short-winged morph with no obvious fitness advantages over the long-winged morph

open access: yesEuropean Journal of Entomology, 2013
A short-winged morph, whose occurrence is controlled by a simple recessive Mendelian unit, was recently discovered in Locusta migratoria. The existence of trade-offs between flight capability associated with wing length and other fitness-related traits ...

Invasive insect colonisation shapes the population distribution of an island‐endemic scaly cricket

open access: yesInsect Conservation and Diversity, EarlyView.
I assessed whether non‐native insect colonisation altered the population distribution of one case study island‐endemic insect: Discophallus ascension of volcanic Ascension Island in the South Atlantic. Invasive ants and crickets had strongly reduced D.

Comparative analysis of the location of rDNA in the Palaearctic bushcricket genus Isophya (Orthoptera: Tettigoniidae: Phaneropterinae)

open access: yesEuropean 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 ...

Native insect species should be selected for classroom rearings

open access: yesInsect Conservation and Diversity, EarlyView.
Rearing insects in the school classroom can build positive attitudes towards insects among schoolchildren, which is becoming increasingly important as insect populations decline. Identified frequent use of non‐native insect species, raising environmental and ethical concerns after classroom rearing ends.
