The value of regeneration for insect fauna associated with leaf litter in the Brazilian savanna: A comparative study of biomass and trophic structure

open access: yesAnnals of Applied Biology, Volume 188, Issue 3, Page 875-888, May 2026.
This study demonstrates the ecological value of natural regeneration in the Brazilian Cerrado by analysing the biomass, richness and trophic structure of leaf litter insects across pasture (P), regenerating (R) and native (N) areas. We found that R areas supported insect communities more similar to N habitats than to Ps, with higher richness, greater ...

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.

Insects Associated with Michigan Bumblebees (\u3ci\u3eBombus\u3c/i\u3e Spp.) [PDF]

open access: yes, 2017
(excerpt) Studies of insect associates of bumblebees are not new. For example, Tuck (1896, 1897) reported over 50 species of insects associated with nests of British bumblebees. Sladen (1912) discussed nest associates and parasites of European bumblebees,

Preliminary Functional Group Patterns of Arthropods in a Maize Field and Adjacent Cultivated Refuge Strip in South Africa

open access: yesAustral Entomology, Volume 65, Issue 2, May 2026.
ABSTRACT Agricultural intensification is a major driver of global arthropod declines. Habitat management strategies, such as cultivated refuge strips (CRS), can counteract these effects by enhancing biodiversity, promoting conservation biological control and improving agroecosystem resilience.

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 ...

A systematic review on research trends and commercialised entomopathogenic nematodes: A global perspective

open access: yesAgricultural and Forest Entomology, Volume 28, Issue 2, Page 298-313, May 2026.
Out of 136 identified EPNs, only 18 (8 Steinernema and 6 Heterorhabditis) are commercialised globally, highlighting a major gap between discovery and application. High production costs and inconsistent field efficacy are the leading obstacles to the widespread commercialisation of EPN‐based biocontrol products.

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 ...

Molecular Phylogeny and Strain Genotyping of the Bacterial Endosymbiont Wolbachia Associated With Tuta absoluta Populations

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 5, Page 387-397, May 2026.
This study was designed to understand the association between reproductive endosymbiotic bacteria and wild and laboratory‐reared Tuta absoluta populations. The majority of T. absoluta populations showed Wolbachia presence at varying levels of infection, whereas Arsenophonus, Cardinium, and Spiroplasma were not detected. Wolbachia‐positive T.

First record of mitochondrial genome of Teredorus nigropennis (Orthoptera: Tetrigidae) and phylogenetic analysis

open access: yesMitochondrial DNA. Part B. Resources, 2020
The nearly complete mitochondrial genome (mitogenome) of Teredorus nigropennis was determined and analyzed. This mitogenome was 14,652 bp in size and encoded 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes.
