Journal of Threatened Taxa 16, no. 7 (July 26, 2024): 25536–44. http://dx.doi.org/10.11609/jott.8686.16.7.25536-25544.
Full textAbstract:
Orthopterans have emerged as a crucial group of invertebrates for environmental monitoring and assessment. According to available literature the study of Moroccan orthopteran species remains limited in comparison to other countries. In recent years, the field of orthopteran classification has witnessed significant progress thanks to groundbreaking research in taxonomy and phylogeny that have shed new light on relationships and evolutionary history. In Morocco, there are many types of Orthoptera, including grasshoppers, crickets, and locusts, and different regions of the country have not been equally well sampled and studied. Notably the northwestern, particularly the Sidi Kacem region, are little studied. Here we present a taxonomic update of the most abundant orthopterans in Morocco based on field visits between spring and summer 2019. Five species were identified: Dociostaurus maroccanus, Aiolopus strepens, Gryllus bimaculatus, Gryllus campestris, and Nemobius sylvestris. We aim to use this publication as a baseline for future work on Orthopterans from northwestern Morocco.

Orthoptera is a diverse arthropod taxon that includes locusts, grouse locusts, short-horned grasshoppers, long-horned grasshoppers, katydids, crickets and mole crickets. They play crucial roles in food chains, nutrient cycling and pollination. The diversity of orthopterans in agroecosystems and grasslands located in the highlands and lowlands of Central Kerala were studied from December 2019 toMarch 2020. The study was conducted in Avoly of Ernakulam District and Venmony of Idukki District in Kerala by employing random sampling in 10 x10 m quadrats. A total of 35 species of orthopterans, belonging to two suborders, 10 families, 20 subfamilies, and 33 genera were recorded. Family Acrididae with fourteen species was the most dominant family followed by Tettigoniidae. Two species namely, Chitaura indica and Burrinia burri are endemic to the state of Kerala. It was found that the ranges of most of the orthopteran genera reported in our study extend all over the South East Asian countries. The highest number of Orthoptera was reported in December in both locations and it decreased towards March. Simpson’s diversity index value shows that both regions harbour a highly diverse orthopteran community. The diversity index value of Venmony is comparatively higher which might be due to the proximity of the study site to the natural forest ecosystem and fewer disturbances. More studies on the orthopteran fauna of Kerala are recommended which would help control their pest status and exploit their economic potential as food in animal husbandry

Full textAbstract:
Types represent the most important specimens in natural history museums as they define a species and should usually be studied within the framework of revisions and new taxon descriptions, hence their documentation is of high importance. Orthoptera is a medium-size order of insects, but its members are important in many food chains as herbivores and as food for other animals. While the documentation of types in Orthoptera is overall very good thanks to the Orthoptera Species File site, there are still many gaps that need to be filled. The Steinhardt Museum of Natural History in Tel Aviv University holds an interesting collection of orthopterans with a focus on local endemics, which have not or only incompletely been documented in the past. Here, we provide a complete annotated catalogue of the 136 type specimens belonging to 29 orthopteran species in the Museum (SMNHTAU, historically TAU), consisting of 21 holotypes and 115 paratypes. The types of Gryllotalpa tali and Myrmecophilus wahrmani, which should be in the collection according to their original descriptions, were not found despite thorough research, and must be considered lost. This catalogue is an important resource for studies on the local fauna as well as for Orthoptera taxonomic research in general.

Full textAbstract:
There are few studies on the Orthoptera of the floodplains, paddy fields, and levee embankments of Japan’s riparian corridors. The research which has been undertaken indicates a relatively rich fauna (33% of Japan’s grasshopper species recorded) with endangered species (e.g. Eusphingonotusjaponicus) found on gravel floodplains, although diversity is restricted by forest cover and unfavorable land uses (e.g. agriculture). Management should focus on the alteration of levee mowing regimes to benefit orthopterans, and the control of invasive plant species and successional processes along river corridors, which appears to be important for grasshoppers of gravel substrates. Integrated Green Grey Infrastructure (IGGI) measures (levee terraces of Asteraceae plants) may enhance populations of Orthoptera and conserve declining plants such as Astertripolium in Tokyo. More research is required throughout Japan to accurately determine the orthopteran fauna and appropriate conservation measures, particularly along super levees and in paddy fields.

Full textAbstract:
Orthoptera is a good indicator taxon of macroclimate changes. In our case study, we analyzed data of orthopterans, vegetation, and macroclimate collected yearly from 2002 through 2017 in Central European humid grasslands. During the study period, the annual mean temperature increased, while the relative abundance of moderately hygrophilic orthopteran species decreased significantly. On the other hand, the species richness and diversity of the assemblages increased due, mostly, to an increase of graminicole/thermophilic species. According to our results, the conservation of the hygrophilic orthopteran assemblages of Central European humid grasslands under global warming can only be ensured by adequate land management, which can at least mitigate the effects of climate change resulting in the warming and drying of humid habitats.

The Orthoptera have inhabited the Earth for ca 300 million years and today include about 25,000 described species. Although orthopterans are mainly known to the general public by their most conspicuous species such as rangeland grasshoppers, locusts, katydids and crickets, they include an amazing diversity of forms and life-styles. In this review, I bring together a series of facts about orthopteran biology that demonstrate their enormous biodiversity, concentrating on ecological and evolutionary characteristics such as habitat variation, modes of feeding, defense mechanisms and phase transformation. In a second part of this review I will consider subjects of more direct human interest as their use as food, their importance in folk medicine and their role as entertainment.

Full textAbstract:
European flood defense embankments form an excellent habitat for Orthoptera. To be effective against storms, these vegetated earth embankments have to be managed by grazing or mowing. However, grazing can impact invertebrates such as grasshoppers and crickets (Orthoptera). This management can lead to dispersal toward undisturbed grassland and reductions in the quality of habitat, food resources and oviposition sites. In most cases, orthopteran insects require heterogeneous vegetation patches with swards of varying height. The impact of grazing depends on the type of livestock; it is very important to choose appropriate animals, timing and intensity. Sheep grazing in late summer (September-October) at a moderate intensity seems to be favorable for Orthoptera. If grazing is carefully monitored, it can promote Orthoptera conservation while maintaining flood defense integrity.

Full textAbstract:
Orthoptera comprise an order of common insects, most of which are phytophagous, but there are also predatory orthoptera. They are found all over the world and adapt to the environmental conditions in which they are found. Orthoptera insects are pests of vegetable plants, destroying large areas, so vegetable growers are familiar with them. The research was carried out in the Amărăștii de Jos stationary in 2020 in vegetable crops. The aim of the research was to identify orthoptera species in vegetable crops and two methods were used to collect them: the beer trap method and the Barber soil trap method). Orthopteran insects were identified with the help of specialized determiners, then classified by family down to species level. Orthoptera currently identified in the stationary studied included six species, namely: Gryllotalpa gryllotalpa, Gryllus campestris, Gryllus desertus, Acrida hungarica, Dociostaurus maroccanus and Calliptamus italicus. The species with the most specimens is Gryllotalpa gryllotalpa (42 specimens) and the species with the fewest specimens is Dociostaurus maroccanus (3 specimens).

Full textAbstract:
Due to its climatic peculiarities, Dobrogea is an area suitable for the development of particular orthopteran populations. Abiotic factors influence the Orthoptera, limiting the number of generations and the abundance. Longitude, latitude and altitude determine the geographical spread of the species, but the main abiotic factors that influence orthopteran populations are the temperature and humidity. Although most species have wide tolerance limits on humidity and temperature variations, these factors directly influence affect the way they feed and reproduce.

Full textAbstract:
A new species of Orthoptera,Parapleurites morrisonensis, is described from the upper Jurassic Morrison Formation of Colorado, USA. This is the first insect described from the Morrison Formation and the first orthopteran described from the Jurassic of North America. No other members of the family Locustopsidae have been described in North America previously, and the other species ofParapleuritesare only known from Siberia. The lack of Jurassic Orthoptera in North America is likely due to a combination of taphonomic variables and collector bias. The discovery ofParapleurites morrisonensisand the potential for finding other Jurassic Orthoptera are important to understanding the evolution of this diverse and widely distributed group.

Orthopteran communities (Insecta, Orthoptera) in grasslands of Eastern Humid Chaco, Argentina Species diversity and abundance of Orthoptera communities were estimated in two grasslands of Eastern Humid Chaco from 2006 to 2007. The greatest species diversity was recorded in the grassland with intensive livestock grazing and predominance of native plant species, whereas the abundance values were higher in the grassland without grazing and characterized by introduced plant species. In total, 25 Orthoptera species were collected during the study. Acrididae (Caelifera) was the most abundant and diverse family recorded. Staurorhectus longicornis, Dichromorpha australis and Orphulella punctata were the most abundant species; the last two species being recorded during the entire sampling period. The greatest abundance was recorded in December 2006. Abundance did not show any correlation with climatic variables.

The data on the distribution and habitat confinement of one Mantodea species and44 Orthoptera species in the Mordovia State Nature Reserve are given. Of these, one species of Orthoptera (Calliptamus italicus) isrecorded for the first time for the Mordovia State Nature Reserve, four species (Mantis religiosa, Phaneroptera falcata, Conocephalusfuscus, Tettigonia caudata) are recently penetrated, one species (Conocephalus fuscus) is reported in the Republic of Mordovia for thefirst time. In the fauna of mantids and orthopterans of the Mordovia Reserve, three ecological groups were identified: polytopic, notconfined to certain biotopes (14 species), hygrophilous representatives of intrazonal habitats (5 species) and xerophiles. Among thelatter, there are species of extrazonal habitats (13 species) and confined to dry pine forests (7 species). The steppe group was notrepresented. For the three key habitats with the largest number of identified species, brief botanical descriptions are given. Factorsinfluencing the species composition and current state of fauna of mantises and orthopterans of the Mordovia Reserve are discussed, andmeasures are proposed for the conservation of vulnerable species.

Full textAbstract:
ABSTRACT Orthopterans are an important component of the food chain. The species belonging to the order Orthoptera are herbivores or predators, and several behave as opportunistic predators. However, their predatory habits are not well understood. Here we report the predation of a Chactopsis sp. scorpion by a Hyperomerus sp. katydid in a fragment of terra firme forest in the western Brazilian Amazon. The specimens were found on a 60-cm tall bush. The scorpion showed spasmodic motions of the metasoma while it was being devoured by the katydid. This is the first report of a predator-prey interaction between an orthopteran and a scorpion in the Amazon biome. We believe that records of this type are important to allow a better understanding of predator-prey interactions in tropical invertebrate communities.

Full textAbstract:
The complete 15,599-bp mitogenome ofAcrida cinereawas determined and compared with that of the other 20 orthopterans. It displays characteristic gene content, genome organization, nucleotide composition, and codon usage found in other Caelifera mitogenomes. Comparison of 21 orthopteran sequences revealed that the tRNAs encoded by the H-strand appear more conserved than those by the L-stand. All tRNAs form the typical clover-leaf structure excepttrnS(agn), and most of the size variation among tRNAs stemmed from the length variation in the arm and loop of TΨC and the loop of DHU. The derived secondary structure models of therrnSandrrnLfrom 21 orthoptera species closely resemble those from other insects on CRW except a considerably enlarged loop of helix 1399 ofrrnSin Caelifera, which is a potentially autapomorphy of Caelifera. In the A+T-rich region, tandem repeats are not only conserved in the closely related mitogenome but also share some conserved motifs in the same subfamily. A stem-loop structure, 16 bp or longer, is likely to be involved in replication initiation in Caelifera and Grylloidea. A long T-stretch (>17 bp) with conserved stem-loop structure next torrnSon the H-strand, bounded by a purine at either end, exists in the three species from Tettigoniidae.

Full textAbstract:
Hard-bodied orthopteran adults, in particular Acrididae, are an important source of insect contaminants in mechanically harvested leafy greens, Brassica spp. Because contaminants are usually detected after greens are fully processed, rejection of these value-added loads can be economically severe. A survey was conducted to determine the level of orthopteran species occurring in and around leafy greens fields prior to mechanical harvesting. This survey demonstrated that the vast majority of individual Orthoptera occurred around the edges of the field prior to harvest. In the second year of the survey, growers were already applying Sevin XLR™ (Aventis CropScience, Research Trangle Park, NC) insecticide to grassy border areas in order to prevent acridid adults from moving into the field before harvest. The main taxonomic groups in Orthoptera found in this survey included Orchelimum sp. (Tettigonidae) (68.8%), Melanoplinae (Acrididae) (18.5%), other Acrididae (5.4%), Schistocerca americana (Drury) (Acrididae) (3.4%), Dissosteira Carolina (Linnaeus) (Acrididae) (2.4%), and other Tettigonidae (1.6%). Insecticide treatment of border areas prior to harvest provided a 94% reduction in Acrididae in the field prior to harvest.

Full textAbstract:
The effect of grazing on Orthoptera assemblages has long been the focus of research worldwide due to the high sensitivity of orthopterans to changes in vegetation structure. According to previous studies, grazing has individual, spatially-different effects on orthopteran assemblages. The current case study was carried out between 2012 and 2016 in a subarea dominated by open sandy grasslands in the Carpathian Basin. The ~70 ha study area was grazed by 250–300 sheep in 2012. In the beginning of 2014, the overgrazing pressure was overall reduced, for the most part, in the examined grassland patches. The study aimed to answer how the complete abandonment of grazing and moderate grazing influences the species richness, diversity and density of the orthopteran assemblages. Investigations in Central European sand steppes confirmed that both intense grazing and the abandonment of grazing have a detrimental effect on the structure of orthopteran assemblages: (a) the Shannon diversity index was higher on moderately grazed sites than on grazed and ungrazed ones; (b) the number of habitat specialists of sandy grasslands was higher on moderately grazed patches than in grazed habitats; and (c) the frequency of geophilic species was higher on grazed patches than on moderately grazed and grazing-abandoned ones.

Order Orthoptera is one of the largest and most important invertebrate groups for environmental monitoring and assessment. Orthoptera faunal composition was carried out at Bharathi Park, Coimbatore, Tamil Nadu, India to evaluate the present status of various species. PAST software was used to perform various statistical analyses to estimate the Orthoptera composition. Overall, 334 individuals belonging to 22 species, 19 genera, 17 tribes under 10 subfamilies, and four families of Orthoptera were recorded. Species richness (59.09%) and species abundance (70.06%) were recorded highest in the Acrididae family followed by Pyrgomorphidae, Tettigoniidae, and Gryllidae. Oedipodinae was the most species-rich (27.27%) and the most abundant subfamily, accounting for 30.24% of the total collected individuals. During the study period, 10 dominant, five intermediate dominance, four incidental, and three rare species were observed. Among these, Spathosternum prasiniferum was found to be the most dominant species (D=18.26) and the least dominant (D = 0.6) species was Euconocephalus pallidus. Based on the principal component analysis, the distribution of species along with the first two PCs (PC1= 33.87% and PC2=28.68%) accounted for the highest variance of the total variances. Cluster analysis showed that Acrotylus humbertianus and Teleogryllus mitratus, Conocephalus maculates and Gryllus bimaculatus Orthopterans were similar to each other. The value of the Shannon diversity index (2.27), Simpson index (0.87), Margalef index (2.2), and α-diversity (5.75) were higher in Acrididae when compared with other families. Value of Evenness (0.93) was highest in Gryllidae. Statistical analysis infers that the richness and abundance percentage of Orthopterans significantly varied between species to species and family to family.

Full textAbstract:
Orthoptera fauna and assemblages of natural and semi-natural grasslands of the Hungarian Lowland are well-known, however, little is known about assemblages living in agricultural and anthropogenic habitats such as arable lands, roadsides, hedges, and riverbanks. Due to climate change, intensification of agriculture, and change of habitat use, these habitat types become increasingly important. To collect data on these mainly unknown habitat types, a three-year study was carried out on the Orthoptera fauna and assemblages of the firth region of the Tisza and Sajó rivers. This area was mainly unknown, and our research contributes to increasing knowledge and provides a base for further investigations. In the 40 sampling sites of the studied region, an occurrence of 30 Orthoptera species was recorded based on 2241 sampled individuals. In this study, we provide 540 new distribution data records of orthopterans that means an almost eightfold increase of the known data. Orthoptera assemblages of different agricultural habitat types showed significant differences considering both species richness and composition. Data suggested that non-cultivated habitat patches of dirt-roads, roadsides and stubble fields and even extensively used pastures, hayfields and alfalfa, red clover, and even wheat fields can preserve relatively species-rich Orthoptera assemblages. Contrary weedy sites of these cultivars and intensively used arable lands (maize, sunflower and rape fields) showed extremely low species diversity.

Sakaerat Biosphere Reserve is one of the four Biosphere Reserves in Thailand. It is situated at Khorat Plateau and comprises of mainly dry evergreen forest and dry dipterocarp forest. Despite studies that document its rich biodiversity, there was no concerted study on the orthopteran diversity. Recent sampling by the authors in Sakaerat led to the discovery of numerous undescribed species. A checklist, first for the place, is also reported here, each species represented with a habitus photograph. In total, 128 species of Orthoptera from 11 families were recorded. Caelifera (grasshoppers) were represented with five families and Ensifera (crickets and katydids) were represented with six families, making up 10 of the 16 lineages in the orthoptera phylogeny.

Cyphoderris strepitans, is a primitive orthopteran which survives only in the mountains of Wyoming and Colorado (Morris and Gwynne 1978). The males rub their forewings together to produce a calling song. This stridulation is presumed to function, as in other acoustic Orthoptera, in attracting conspecific fema1es for mating and in maintaining a broadcast territory around each singer.

Environment is the predominant factor for deciding the appropriation and abundanceof Orthoptera species globally. During present study, the impact of major environmental factors on abrupt occurrence of Orthoptera species was examined. Orthopterans landed on vast agricultural fields of cotton, wheat, maize, sugarcane and other standing crops in fertile parts and sandy regions of district Rahim Yar Khan, Punjab, Pakistan. The survey on different localities of district Rahim Yar Khan, Punjab was conducted from January to December 2019, special attention was paid during rainy season. The total 4908 specimens of order Orthoptera, suborder Caelifera belonged to 8 species were collected from different localities of tehsils Sadiqabad, Rahim Yar Khan, Khanpur and Liaqatpur of district Rahim Yar Khan. The highest number of population, 2080 belonged to Schistocerca gregaria and lowest number of individuals belonged to Acrida exaltata were 135. However, other six species i.e., Peokilocerus pictus, Oxya hyla hyla, Sphingonotus savignyi, Heteracris littoralis, Aiolopus thalassinus thalassinus, Diabolocatantops innotabilis were 1090, 480, 386, 355, 195, 187 respectively. Among them 3472 were males and 1436 were females. The % relative abundance of Orthoptera species recoded from agricultural areas was 61.63 and 38.36 from desert areas. The species diversity indices, richness and equity of agricultural areas were 0.7766, 5.0377, 2.0110 and 0.8600 and sandy areas were 0.5132, 2.3663, 1.5268 and 0.6595 respectively. The highest numbers of specimens collected in the month of October were 1084 due to favourable environmental factors while lowest 112 specimens in the month of January due to unfavourable conditions. The abundance of Orthoptera populations were coincidence with different environmental factors i.e., temperature, humidity and rainfall in different months of year.

The assessment of anthropogenically determined dynamics of entomocomplexes, including a number of economically important and biocenotically significant groups of insects inhabiting open biocenoses of the Pripyat floodplain (Belarusian Polesie) has been given. Some patterns in the formation of hortobiont arthropods complexes in natural and transformedhabitats have been established. There have been registered the representatives of 2 classes -insects (Insecta) and arachnids (Arachnoidea) - in the studied territory. The insects are represented by 9 orders (and 22 families): dragonflies (Odonata), orthopterans (Orthoptera), homopterans (Homoptera), semi-coleopterans (Hemiptera), coleopterans (Coleoptera), neuropterans (Neuroptera), hymenopterans (Hymenoptera), dipterans (Diptera) and lepidopterans (Lepidoptera). The most widespread representatives of 6 orders of insects are Diptera, Coleoptera, Orthoptera, Homoptera, Hemiptera. Dipterans predominate in all biotopes, their proportion is up to 40 % of all insects. Orthopterans dominate by biomass everywhere. The structure of entomocomplexes in the studied biocenoses has been established: qualitative composition and quantitative characteristics (abundance and biomass). It is shown that the number of Coleoptera is reduced by almost 2.5 times on pastures compared to the control, while for Hemiptera and Orthoptera, on the contrary, increased. Hygrophiles are replaced by more meso- and xerophilous species. A high number of white-banded filly Chorthippus albomarginatus (De Geer, 1773), a well-known pest of farmland, has been recorded in agrocenoses (an order of magnitude higher than in natural meadows). The disappearance of grasshoppers (indicators of reserved state) from communities has been noted as the anthropogenic load on biogeocenoses increases. The tendency of changes in the structural and functional organization of entomocomplexes has been revealed, it manifests itself in the change of species differing in hygropreferendum. Thus, hygrophilous stenobionts are replaced by mesophilic and mesoxerophilic species and elements of steppe (Stenobothrus lineatus), semi-desert (Gomphocerippus rufus) and even desert (Bryodemella tuberculata) fauna. The bioindicational significance of individual groups and species of insects, demonstrated on orthopterans, has been established.

Rice fields are one of the most important ecosystems because rice fields can produce staple food which is very important for humans. The condition of the rice fields in Ngabean Village, Secang District, is where many Orthoptera are found. The potential of the environment can be used as a learning resource, but currently it is still not optimal. The unidentification of Orthoptera in the rice fields of Ngabean Village, Secang District is something that has the potential to be developed. So it is necessary to identify the Orthoptera order in the rice fields in Ngabean Village, Secang District as a reference book. This research aims to determine the results of Orthoptera identification, the abiotic factors that influence it, and the feasibility of the biology reference book being developed. This research uses mixed method research which is divided into two stages, namely exploratory qualitative research and Research and Development (R&D) development research with the 4-D development model. However, this research only reached the third stage, namely develop. Data collection was carried out by Ortopthera exploration in the rice fields of Ngabean Village, Secang District. Analysis of the feasibility of reference books was carried out with validation from material experts and media experts. Apart from that, readability tests were carried out by entomology lecturers and students. The research results found 15 species of Orthopthera.

An annotated list of 42 species in 26 genera and four families of Orthoptera recorded from Beringia (Northeast Yakutia, Chukotka, Magadan region, and Kamchatka in Russia, Alaska in USA, Yukon and the Northwestern Territories in Canada) is given. The distribution of species is clarified. The exchange of orthopteran faunas between Asia and America by the Bering Land Bridge in Pleistocene was strongly limited. The only three species, Tetrix subulata (Linnaeus, 1761), Melanoplus frigidus (Boheman, 1846), and Stethophyma grossum (Linnaeus, 1758), are recorded from both Asian and American parts. The orthopteran fauna of Beringia is not original. Majority of Beringian species are widespread throughout either Asia or North America. There are only four endemic grasshoppers, namely two Asian subspesies, Melanoplus frigidus kamtchatkae (Sjosted, 1935) and Aeropedellus variegatus gelidus Mistshenko, 1951, and two American species, A. arcticus Hebard, 1935 and Bruneria yukonensis Vickery, 1969. Composition of the regional faunas is briefly discussed. The monotypic genus Bohemanella Ramme, 1951 is again considered as a synonym of Melanoplus Stål, 1873, where a type species of the former genus, Melanoplus frigidus (Boheman, 1846) comb. resurr., forming its own species group.

Full textAbstract:
Abstract The native bracken fern (Pteridium aquilinum (L.) Kuhn) has become increasingly invasive in abandoned or undergrazed Alpine grasslands. Bracken stands are generally assumed to be poor in species, but there is still very little information about the impact on the fauna. We recorded Orthoptera communities of 24 sample plots with varying bracken cover. Compared to plots with only sparse or medium bracken cover, species richness was highly significantly lower in densely overgrown plots, while the former two did not differ markedly. Multivariate ordination analyses revealed gradients with unequal orthopteran communities, showing distinct patterns of bracken cover clustering. Based on indicator values, 13 of 23 Orthoptera species turned out to be significantly or marginally significantly associated with a single bracken cover stratum or a combination of two strata, whereby all nine Red List species were primarily restricted to sparse or medium bracken cover. However, some generalist species were found to favor denser bracken stands, such as Tettigonia viridissima, contributing to the local Orthoptera beta diversity. Our data suggest that ongoing rotational sheep grazing with temporary paddocks is regarded as the most preferable management system. However, selected parts of the study area, which have only sparse vegetation and no pressure of bracken or scrub overgrowth, are recommended to be alternately left ungrazed for a few years to allow for the coexistence of different successional stages. Low-intensity bracken control measures, situationally by mowing or uprooting, are considered appropriate and should be pursued. Implications for insect conservation Even though most specialized and rare Orthoptera species in Western Europe tend to prefer sparsely vegetated areas, subareas with medium to even dense vegetation cover might promote certain generalist species, leading to a higher local species richness.

Madagascar has a long history of using Orthoptera as food and feed. Our understanding of the biological diversity of this resource, its contemporary use, and its future potentials in Madagascar is extremely limited. The present study contributes basic knowledge of the biological diversity and local uses of edible Orthoptera in Malagasy food cultures. Data was collected with key informants in 47 localities covering most of the ecoregions of Madagascar and corresponding to 12 of the 19 ethnic groups. Orthoptera are consumed throughout Madagascar. We report 37 edible Orthoptera species, of which 28 are new species records of edible Orthoptera in Madagascar and 24 are new species records of edible Orthoptera in the world. Most species are endemic and occur in farming zones. Children are the primary collectors and consumers of edible Orthoptera. The insects are eaten both as snacks and main meals. Edible Orthoptera are primarily collected casually and marketing is rare, with the notable exceptions of the large cricket Brachytrupes membranaceus colosseus and during locust outbreaks (e.g., Locusta migratoria). The use of Orthoptera as feed seems rare. Further investigations of cultural and personal preferences are required to assess the future potential roles of Orthoptera in Malagasy food habits.

Sword-tailed crickets of the genus Amusurgus Brunner von Wattenwyl, 1893 (Orthoptera: Trigonidiidae: Trigonidiinae) from Southeast Asia is still poorly known and its taxonomy requires a revision. Many species are still awaiting discovery and formal description. Based on newly-acquired materials from the mangrove in Singapore, a new species of Amusurgus is described: Amusurgus (Amusurgus) caerulus sp. nov. This discovery also demonstrates that even in a small country like Singapore, we still do not have a comprehensive understanding of its orthopteran diversity.

Full textAbstract:
The X0♂/XX♀ sex chromosome system prevails in most Orthopteran species. The X chromosome stands as one of the largest chromosomes within the complement, and is characterized by its heterochromatic nature. Variations of this model were found in some species of grasshoppers, crickets, and katydids, based on X/autosome rearrangements, giving rise to new sex chromosome systems, such as neo-XY♂/XX♀ and neo-X1X2Y♂/X1X1X2X2♀. The sex chromosome system neo-X1X20♂/X1X1X2X2♀ is rare in Orthoptera, and was observed only in two cricket species. In this study, we present the first multiple chiasmatic sex chromosome system in Orthoptera, found in the tree cricket Oecanthus rubromaculatus Zefa, 2022 from two distinct locations in the State of Rio Grande do Sul, Brazil. In one location, individuals exhibited a karyotype with 2n = 12, X1X2Y1Y2♂/X1X1X2X2♀, while in the other a karyotype of 2n = 12, X1X2X3Y1Y2Y3♂/X1X1X2X2X3X3♀ was observed. We proposed a model to explain the evolutionary steps in the formation of these karyotypes, based on chromosomal information of the Neotropical Oecanthus’ species. In this context, we proposed a hypothesis to explain the chromosome reorganization in O. rubromaculatus, starting from an ancestral karyotype of 2n = 21, X0♂, like the karyotype found in Oecanthus pictus Milach & Zefa, 2015, resulting in a significant reduction to 2n = 12 in O. rubromaculatus. This reorganization has led to the emergence of the novel multiple sex chromosome system in Orthoptera.

Abstract The Carpathian Mountains, particularly the Eastern Carpathians, represent an area with a high diversity and endemism in grasshoppers and bush-crickets. The well-preserved mountain grassland habitats are populated by diverse orthopteran assemblages. During the second half of July 2013, we visited 24 sites in Romanian Carpathians within altitudes ranging from 237 to 1700 m a.s.l. and found 71 Orthoptera species (36 Ensifera and 35 Caelifera). These represent 37.3% of the 190 species known to occur in Romania. Nine Carpathian endemics (Isophya stysi, Pholidoptera frivaldskyi, Pholidoptera transsylvanica, Miramella ebneri, Pseudopodisma transilvanica, Isophya harzi, Isophya nagyi, Isophya sicula, Zubovskya banatica), of which the last four are endemic to Romania and Eastern Carpathians, were recorded. Four environmental characteristics, i.e. habitat type, altitude, mean temperature and precipitation on sampled sites, are used to examine the structure of orthopteran assemblages by using DCA. Also, more detailed information on the occurrence of rare and endemic species is given.

Full textAbstract:
Among insects orders, Blattodea and Orthoptera are characteristic with their high significance to human habitation, as posing medical and agricultural problems. Representatives of Blattodea have an important role as carriers of a number of infectious diseases in humans and animals, and are directly related to human life and activities. On the other hand Orthoptera are very significant as agricultural pests that cause great damage to plants. The study of the mechanisms of immune defense and the processes related to the response against pathogenic infections in these two orders is of interest in order to more fully clarify the possibilities for management and control of their populations. This review summarizes the information on the defense mechanisms (hemocytes, antimicrobial peptides, pathogen recognition, signaling patways, immune and antiviral responses) studied in representatives of these two orders. The list includes 30 species of cockroaches and termites and 59 orthopteran species, and focuses on species with medical significance (Periplaneta americana, Blattella germanica) and insect pests for agriculture such as Locusta migratoria and Schistocerca gregaria.

Thanks to scientific expeditions and entomological missions, 2155 Orthoptera belonging to 118 species of five subfamilies of Tettigoniidae have currently been studied. Examined material is here listed with its known distribution. New genera and species have been found and here described: Eurycoplangiodes sanghaensis Massa, n. gen. and n. sp. Paraeulioptera emitflesti Massa, n. gen. and n. sp., Paraeurycorypha Massa, n. gen. ocellata Massa et Annoyer, n. sp., Arantia (Arantia) gretae Massa, n. sp., Arantia (Euarantia) syssamagalei Massa et Annoyer, n. sp. and Dapanera brevistylata Massa, n. sp. Overall, from 2012 to 2020, the study of the orthopteran material collected in the scientific expeditions to Central Africa carried out since 1984, enabled the description of 6 new genera and 27 new species. They represent 22.8% of the total amount of species currently recorded in the protected areas where this scientific activity has been carried out. This demonstrates that these areas still hold a high number of new species, representing a biodiversity hotspot.

Full textAbstract:
Exhibiting manifold ecological impacts on terrestrial biota, roads have become a major driver of environmental change nowadays. However, many insect groups with high indication potential, such as grasshoppers and crickets (Orthoptera), have been largely neglected in road ecology research from a functional perspective. Using two complementary sampling methods, we have investigated the spatial dynamics of functional diversity and six functional traits in orthopteran assemblages, with respect to motorway proximity and the associated environmental factors, in a grassland habitat in the Lika region, Croatia. This research shows, for the first time, that road proximity can facilitate an increase in the functional diversity of orthopteran assemblages, with shifts in functional traits related to mobility, feeding habits and lifestyle being primarily driven by changes in vegetation height. Our findings also suggest that our ability to detect road-related patterns depends on the choice of a diversity measure and sampling method, since different components of orthopteran assemblages (plant-dwelling vs. ground-dwelling) exhibit different functional responses to road proximity.

To understand how farmlands help maintain biodiversity, we investigated the relationship between habitat heterogeneity and Orthoptera community composition on multiple spatial scales. First, we determined the impact of 12 environmental variables on the Orthoptera community diversity by sampling 37 quadrats in uncultivated fields over a broad spatial scale. Canonical correspondence analysis (CCA) demonstrated that environmental parameters influenced species composition. The first two canonical axes were associated with forest cover, grass (including harvested dried grass in some cases), bare or paddy fields, and plants with tall stems. Secondly, we conducted a local-scale survey of Orthoptera assemblages in an operational farm unit consisting of paddy fields, fallow fields, marginal grass fields, and secondary forests. Eleven Orthoptera species (46%) were found exclusively on specific vegetation types. Thirdly, we carried out a habitat-scale survey to elucidate the correspondence between consecutive spatial changes in vegetation and Orthoptera community composition in a paddy field and surrounding marginal fields. Even within narrower ranges, the compositional habitat heterogeneity induced changes in the dominant Orthoptera species composition. These results indicate that a high degree of habitat segregation occurs among Orthoptera species in field margins and in uncultivated fields, and that farmland management significantly affects spatial distribution of Orthoptera.

The Orthoptera, comprising grasshoppers, crickets, and katydids, is diverse and species rich in tropical Southeast Asia, including the island of Borneo. However, not every part of Southeast Asia is equally well sampled and studied. This includes Brunei Darussalam, specifically at the Kuala Belalong Field Studies Centre (KBFSC) within the Ulu Temburong National Park. We present here an annotated and illustrated checklist of Orthoptera from the primary dipterocarp forest around Kuala Belalong based on three field trips in 2016 and 2017. We provide notes on their taxonomy (including how each species was identified) and natural history of species. In total, 72 species were recorded, representing eight of the 16 monophyletic orthopteran superfamilies. In total, 73.6% of all species recorded were singletons and doubletons, indicating that many species are probably rare. The collection led to the discovery of ten species new to science already published separately, with more expected to be described from pending material and confirmation. More species, including undescribed ones (at least four new species), are expected with continued sampling effort. Despite the 21 day-long surveying efforts from three trips around KBFSC, we believe that the species list provided here is non-exhaustive and only a preliminary one.

Full textAbstract:
The Balkan peninsula is an important biogeographic region of Europe which houses the Dinaric Alps, a mountain range rich in biodiversity. The fauna of Orthoptera has, in recent years, been an important subject of study in Croatia, but many of the Dinaric mountains in Croatia remain poorly sampled. Bosnia and Herzegovina, with the exception of some foreign expeditions, remains almost completely unknown with regards to the distribution of Orthoptera. This paper presents the inventory of the orthopteran faunas of Dinara, Svilaja, Kamešnica, and Troglav mountains and Livanjsko polje, with research conducted in Croatia and Bosnia and Herzegovina in 2021 and 2022. A total of 67 localities were visited and 115 species were recorded. For each species in each locality, a simple abundance estimation was carried out and is reported here. A comparative checklist of species is provided, combining the literature and newly gathered data. Although many species were recorded, most of the visited areas would benefit from more research. Recently, with the establishment of Dinara Nature Park, conservation efforts in Croatia have increased but the same cannot be said for Bosnia and Herzegovina, where more conservation work is required.

Abstract We present the species checklist of Orthoptera in the Forest Area with Special Purpose/KHDTK Aek Nauli, Simalungun Regency, North Sumatra, Indonesia. The checklist is provided as a basic information on the grasshopper diversity and species assemblage in the forest region. KHDTK Aek Nauli is classified into a tropical montane forest with an elevation of 1,100–1,750 m a.s.l dominated by the pine species and intended as an ex situ conservation for Sumatran Elephant (Elephas maximus sumatranus). Sampling of grasshoppers was conducted for four consecutive days using two methods namely pit fall trap and sweeping net with a total of 12 sampling points. Approximately of 21 orthopteran species from 97 individuals belonging to suborder Ensifera (12 species) and suborder Caelifera (9 species) were documented. The highest Importance Value Index (IVI) orthopteran species was obtained from Paratettix curtipennis (102.92), followed by Teleogryllus emma (79.04), Oxya intricata (69.67), and etc. All grasshoppers were commonly identified for Asiatic region to worldwide distribution.

The higher taxa classification and phylogeny of the insect order Orthoptera have long been controversial. Hexamerin, as a member of the highly conserved arthropod hemocyanin superfamily, has been shown to be a good marker for the phylogenetic study of insects. However, few studies have used hexamerins on the phylogeny of Orthoptera. In this study, we determined twenty-seven different hexamerin subunit type sequences in seventeen speices of Orthoptera. In order to infer the phylogenetic relationships among the superfamilies within Orthoptera and test the monophyly of Orthoptera, phylogenic trees were reconstructed using Neighbor-Joining (NJ) and Bayesian inference (BI) methods with two dipluran and three hymenopteran hexamerin sequences as outgroups. The result supported the monophyly of Orthoptera, which includes two monophyletic suborders Caelifera and Ensifera. The Caelifera includes Acridoidea, Eumastacoidea, Tetrigoidea and Tridactyloidea, and the Ensifera includes Tettigonioidea, Grylloidea and Gryllotalpoidea. Our study is basically consistent with the study of morphological classification. In addition, our study indicates that a relatively comprehensive taxa sampling is essential to solve some problems in phylogenetic reconstruction.

AbstractOrthopterans are well known to represent the majority of insect biomass in many grassland ecosystems. However, the verification of a relationship between the traditional descriptors of orthopteran assemblage structure and plant community patterns is not straightforward. We explore the usefulness of the concept of life forms to provide insights on such ecosystem level relationship. For this purpose, thirty sample sites in semi-natural calcareous grasslands were classified according to the relative proportion of dominant herbaceous plant life forms. Orthopteran species were grouped in four categories, based on the Bei-Bienko’s life form categorization. The association among plant communities, orthopteran assemblages and environmental factors was tested by means of canonical correspondence analysis. Orthoptera groups were found to be associated with distinct plant communities, also indicating the effect of vegetation change on orthopteran assemblages. In particular, geobionta species were associated with all the most disturbed plant communities, while chortobionta and thamnobionta seemed to be dependent on better preserved grassland types. Therefore, the use of life forms could help informing on the relationships of orthopteran assemblages with grassland conservation state. Information on such community relationships at the local scale could also assist managers in the interpretation of habitat change maps in terms of biodiversity changes.

In the Southern-Mezőföld the different sized and mosaic-like patches of various surfaces of sandy and loess grasslands, marshes and marshy fields are an lesser-known area for entomologist. There are rich Orthoptera fauna: 45 species were detected between 2005 and 2008. The Orthoptera assemblages of the marshy fields and sandy grasslands were separated in the CoA scattergram. Tree diagram of the Orthoptera species made by cluster analysis shows four correlated groups on the basis of their occurrence rates. Correlation between the degradation and homogeneity of the habitats and the number and density of the Orthoptera species were also observed.

Full textAbstract:
After the revision of several fossils and observations of recent taxa, we propose a new interpretation of the wing venation pattern for the ‘orthopteroid lineage’. The Orthoptera and several taxa previously assigned to the paraphyletic group ‘Protorthoptera’ are included in a common clade, Archaeorthoptera taxon nov. The Orthoptera and some closest relative groups are included in the Panorthoptera sensu nov. These assignments are based on new autapomorphies based on venation patterns. A cladistic phylogenetic analysis of the Orthoptera is performed for the first time on the fossil record of this group, based on 74 characters (131 informative states). Three taxa assigned to the Archaeorthoptera nec Panorthoptera compose the outgroup. The ingroup is composed of three Panorthoptera nec Orthoptera and 63 Orthoptera, mainly from the Palaeozoic and Mesozoic. Following this initial phylogeny, we propose several nomenclatural changes; the Ensifera are redefined and the relationships between Caelifera and Ensifera sensu nov., and those between the major clades of modern Ensifera sensu nov., are clarified. Relationships within the ‘oedischioid’ stem-group remain unclear. The evolution of the venational structures within the Orthoptera is discussed and in this analysis the Orthoptera were not clearly affected by the Permo-Triassic biodiversity “crisis”. The capacity of the fossil taxa to be used in phylogenetic analyses is discussed, using the example of the ‘orthopteroid’ insects.
