ABSTRACT Taphronota thaelephora Stal. 1873 is generating a lot of interest for biological and cytogenetic studies because it has demonstrated the potential for a future veritable pest in Cameroon. The lack of previously established karyotype for the species has necessitated this study. Testes from five adult individuals collected from Balepa - Mbouda in the West Region of Cameroon and treated with 1% colchicine were analyzed using the Lactic-Propionic Orcein squash technique. Mitotic metaphase chromosomes were measured directly from the microscope and pictures taken with the help of the Lietz photomicroscope. Pictures were processed with the Microsoft Office Picture Manager. The species revealed the standard Pyrgomorphidae karyotype of 2n ♂= 19 acrocentric chromosomes. Mean length of the chromosomes ranged from 8.10±1.7 to 3.75±0.0 µm. Analysis of Relative Chromosome Lengths (RCL) revealed three distinct size groups of long, medium and short. The karyotype of T. thaelephora was made up of 2 pairs of long chromosomes (2LL) and the X-chromosome, 6 pairs of medium chromosomes (6MM) and 1 pair of short chromosomes (1SS).

  • Recolonisation Patterns of Orthopteran Species in Successional Stages of Revegetated Coal Mine Sites
    HALTERES, Volume 4, 1-11, 2013 ISSN 0973-1555 © SHBBIR R KHAN AND NEELKAMAL RASTOGI Recolonisation patterns of orthopteran species in successional stages of revegetated coal mine sites Shbbir R Khan and Neelkamal Rastogi * Insect Behavioural Ecology Laboratory, Department of Zoology, Centre of Advanced Study, Banaras Hindu University, Varanasi – 221 005, U.P., India (*e-mail: [email protected]) Abstract The diversity and abundance of insects belonging to the order Orthoptera was studied in coal mine spoils of different ages (0- 10 year old) located in Singrauli and the adjoining border area between Uttar Pradesh and Madhya Pradesh in India. The abundance of the 21 orthopteran species (belonging to 16 genera) showed significant variations in 0-8 year old mine sites relative to the 10 year old reference site. Orthopteran alpha diversity increased sharply in the 2 year old site. The gradual increase in alpha diversity in the 4-10 year old sites did not demonstrate any significant differences. However, abundance and number of grasshopper species showed a clear linear increase with increase with mine site rehabilitation. Overlap in orthopteran rank abundance curves obtained for 4-10 year old sites is probably due to differences in the occurrence, abundance and diversity patterns of grasshopper and cricket species with increase in mine site rehabilitation age. Our results demonstrate that grasshopper species assemblages are highly sensitive to variations in the level of anthropogenically-caused disturbance, due to mining activities. Thus, the abundance patterns of grasshoppers, including those of habitat specialists, may be of significance in evaluation of the restoration progress in degraded ecosystems, such as mine sites.

  • ABSTRACT BUTLER, ERIC MICHAEL. Habitat
    ABSTRACT BUTLER, ERIC MICHAEL. Habitat Selection and Anti-Predator Responses of Acridid Grasshoppers. (Under the direction of Marianne Niedzlek-Feaver and Harold Heatwole.) Most prey species use a variety of defenses to prevent their capture by predators. Habitat can have both direct effects on the effectiveness of these defenses by providing refuges, the backgrounds against which prey species are camouflaged, and, indirectly, by altering exposure to the predator community of the broader region. Grasshoppers are found in multi-species assemblages in geographically-proximate micro-habitats and are subject to a number of predators from a wide variety of taxa. The main defenses of most grasshoppers are the opposed strategies of hiding and fleeing. More structurally-complex habitats should favor hiding while more open habitats should favor fleeing. To test this hypothesis I evaluated the micro-habitat preferences of nine species of sympatric grasshoppers found in fields at Raleigh, North Carolina. While several species had distinct preferences for habitats with taller or shorter vegetation, the presence or absence of vegetative cover was an important factor for nearly all species. Escape behavior was also recorded for all nine species. Species-specific differences were seen in flight-initiation distances and flight distances. Camouflage was evaluated using a computer program in which humans tried to locate camouflaged grasshoppers as rapidly as possible. Because any close correlation between camouflage and habitat assumes that camouflage will be lost if it is superseded by other defenses in a given habitat, this assumption was investigated. Twenty-one island- endemic species of birds and mammals that have few to no predators when compared to their closest relatives on the mainland were located.

  • Grasshopper Country Before and After: a Resurvey of Ken Key's Collecting
    bs_bs_banner Austral Entomology (2020) ••, ••–•• Grasshopper country before and after: a resurvey of Ken Key’s collecting expeditions in New South Wales, Australia, 70 years on Michael R Kearney,1* Md Anwar Hossain,1 Steve J Sinclair2 and Hojun Song3 1School of BioSciences, The University of Melbourne, Parkville, Vic. 3010, Australia. 2Arthur Rylah Institute for Environmental Research, Department of Environment, Land, Water and Planning, Heidelberg, Vic. Australia. 3Department of Entomology, Texas A&M University, College Station, TX USA. Abstract Recent reports of insect declines across Europe and other parts of the world have emphasised the generally poor baseline that exists for assessing changes in biodiversity. One important source of untapped baseline distribution data is field notebooks, which are often associated with the collection activities of museums and other scientific institutions and may be decades or even centuries old. Over 220 field notebooks are associated with the grasshopper (Caelifera) collection in the Australian National Insect Collection, containing detailed notes on the times and places species were collected as well as vegetation and soil descriptions. In 2019, we resurveyed 45 locations from three of these notebooks from the 1940s, to assess the potential value of larger-scale efforts in the future. We found substantial differences in grasshopper species richness and composition between the surveys; richness was generally higher in our survey, and some species showed dramatic increases in range and occurrence, whereas others remained relatively static. There was also evidence for vegetation state transitions in some areas, including increased weediness and shrub thickening, which may be associated with changes in the grasshopper fauna.

This species is endemic to NSW, the ACT and Victoria. The main reasons for this species being eligible are i) inferred restricted geographical range (AOO = 124 km2), ii) severe fragmentation, iii) historical and inferred ongoing decline in abundance, habitat availability and quality and iv) ongoing threats (and poorly understood management requirements). This species was the focus of early chromosomal research (see Grodwohl 2017 for a summary) and unlike many insects, there was extensive survey work performed in the past which along with recent surveys of known sites, allows an historical assessment of the species’ decline. This species is now locally extinct at many previously known locations. Description and Taxonomy Keyacris scurra (Rehn 1952) Key’s Matchstick Grasshopper is a small (females ~25 mm, males ~18mm), slender, wingless grasshopper characterised by its slanted face, splayed hind femora and ensiform antennae. This species occurs in several colour forms, with brown being the most common (Farrow 2018).

II Male germ line karyotypic instability in Gastrimargus§ H CHANNAVEERAPPA* and H A RANGANATH† Department of Studies in Zoology, University of Mysore, Manasagangotri, Mysore 570006, India *Government College for Women, Mandya 571401, India MS received 26 April 1996; revised 20 September 1996 Abstract. Gastrimargus africanus orientalis, an acridid grasshopper has revealed the existence of karyotypic mosaicism in the male germ line cells of a few individuals with 2n = 23, 19, 21, 25 and 27 chromosomes. Details of this chromosomal instability are presented in this paper. Keywords. Karyology; south Indian acridids; male germ line; karyotypic instability; Gastrimargus africanus orientalis. 1. Introduction The karyotype is an important asset of a species. In spite of 'polymorphism', the architecture and composition of a species karyotype is relatively stable. The karyology of acridid grasshoppers presents a very stable phenotype over a wide range of species. It is often quoted as an example for "karyotypic conservatism" (White 1973; Ashwath 1981; Yadav and Yadav 1993). But Gastrimargus, an acridid, illustrates a facet of 'karyotypic dynamism' with a rare phenomenon of aneuploids in the male germ line and the same is presented in this paper. 2. Materials and methods The individuals of Gastrimargus africanus orientalis Saussure were collected from Mandya (Karnataka) during 1993-95. A total of 128 individuals (94 males and 34 females) were analised. Adult testis/ovarian follicles and intestinal caecae were removed and fixed in 3:1 methanol and glacial acetic acid.
