Summary: Orthoptera have the largest genomes among insects. Comparative cytological data of 339 genera and 769 species of Caelifera revealed that chromosome numbers are highly conserved in the grasshopper family Acrididae, but have diverged independently in other groups.

Summary: This study investigates the role of chromosome rearrangements in the evolution and speciation of Grasshoppers in the genus Ronderosia. The findings suggest that chromosome rearrangements play a central role in generating variability in chromosome number and the formation of a neo-sex chromosome system (neo-SCS). The study also highlights the need for further genomic studies to better understand the mechanisms behind these chromosomal rearrangements.

Summary: This study measured the genome size (GS) of 62 grasshopper species using flow cytometry and assembled 10 new mitochondrial genomes for comparative phylogenetic analyses. Some grasshopper species with giant GS exceeding the previous insect record were discovered. The results support the neutral or near-neutral hypotheses of GS evolution, but also indicate heterogeneity in the evolutionary dynamics of GS in grasshoppers.

Summary: The phylogeny of many groups of Orthoptera remains poorly understood. This study utilized transcriptome sequencing to investigate the phylogeny of the Chorthippus biguttulus complex and related Gomphocerinae species. The results highlight the importance of using nuclear multispecies coalescent methods for studying young radiations and underscore the need for further taxonomic revision in Gomphocerinae grasshoppers.

Summary: Chemoreception plays a crucial role in the reproduction and survival of insects. This review focuses on the chemosensory systems and chemical ecology of short-horned grasshoppers, with a discussion on the applications of genome editing and entomopathogenic microorganisms in controlling locusts.

Summary: This study investigated hybridization patterns between two fish species in the central and southern United States and the role of chromosomal rearrangements in reproductive isolation. The results showed significant variation in hybridization rates among different drainages, which were associated with population phylogeography rather than chromosomal fusions, suggesting the importance of population history in explaining hybridization variation.

Summary: The comparative analysis of the internal and external male genitalia of the Abracrini grasshoppers was conducted, including representatives of the type species of the genera, specimens compared with the same or more representative specimens of the genus, and bibliography data. Schematic illustrations pointing to the morphological differences between the genitalia were included, along with a dichotomous key to the 21 Abracrini genera.

Summary: The study investigated the effects of non-Robertsonian translocation with chromosome fusion (N-RBCF) on preimplantation embryos. Results showed that blastocysts from N-RBCF carriers with Y fusion had a low number of unbalanced translocations, while the risk of unbalanced translocation in autosomal N-RBCF was higher than in Robertsonian translocation, especially in male carriers.

Summary: The study focused on the vole species Alexandromys evoronensis, which is endemic to the Russian Far East, specifically looking at its Evoron and Argi chromosomal races. It discovered tandem and Robertsonian rearrangements in both Evoron and Argi chromosomal races, involving different numbers of chromosomes in each race.

Summary: Short-horned grasshoppers play important roles in grassland ecosystems, and some species cause significant damage to rangelands. A recent survey in Oklahoma, combined with examination of museum specimens, resulted in the discovery of five new state records and 734 new county records for short-horned grasshoppers. The data update the distribution of economically important species and species of conservation concern.

Summary: Despite its advantages, DNA barcoding often fails to accurately identify species, and the reasons for this have rarely been tested. In this study, the potential causes for low barcoding performance were explored in four Chorthippus grasshopper species, and nuclear copies of mitochondrial genes (NUMTs), contamination, and recent hybridization were ruled out as possible explanations. The study also estimated the mutation rates of nuclear and mitochondrial genes and found that these grasshoppers did not have a particularly low mitochondrial mutation rate compared to other insects. Coalescence simulation suggested that two demographic scenarios provided a good fit to the mitochondrial genealogies in three of the four species, while the mitochondrial genealogy of Chorthippus mollis indicated an adaptive selection rather than neutral evolution pattern.

Summary: This study aimed to test the effectiveness of the entomopathogenic fungi Beauveria bassiana as a biocontrol agent on six harmful grasshopper species in Argentina. Significant differences in pathogenicity were observed for B. bassiana on third-instar nymphs of different grasshopper species. The results suggest that B. bassiana LPSc 1067 may be a promising biological control agent for Trimerotropis pallidipennis and Dichroplus maculipennis.
