Fedor, Jaroslav Holu5a, Oto Majzlan and Pavol Prokop Abstract The Heath Bush-cricket (Gampsocleis glabra) can be considered as a really xerothermophilous species preferring dry and warm steppe-like formations, quite intolerant to different or changed ecological conditions. Although this Euro-Asian bush-cricket occurs in many European countries, the distribution in Slovakia can be still classified as "mystic and unclear". However several records have been published on its presence from Slovakia (E and SW) and the Czech Republic (N). The references hinted at the fact that G. g/abra seemed to appear just in Eastern Slovakia on its South close to the boundary with Hungary. However in the 90's the species was collected in South-Western Slovakia, especially in the surround- ings of the Danube River. Due to a lack of sufficient information on the occur- rence of G. glabra in Slovakia as well as in the Czech Republic it seems to be difficult to define the exact ecosozological status of the species and to determine relevant activities for its conservation. Since the main threat seems to be con- nected with the destruction of real and potential localities, conservation efforts should be proposed from this point of view. Zusammenfassung Die Heideschrecke (Gampsocleis glabra) ist eine ausgesprochen xerothermo- phile Art, die trockenwarme, steppendhnliche Lebensriiume bewohnt und sehr empfindlich auf Anderungen der Habitatbedingungen reagiert. Obwohl diese eu- rasische Laubheuschrecke in einigen Ldndern Europas vorkommt, ist ihre Verbreitung in der Slowakischen und Tschechischen Republik noch weitgehend unklar. Es liegen einzelne publizierte Nachweise der Art aus beiden Ldndern vor. UrsprUnglich wurde angenommen, G. glabra kdme in der Slowakei nur im Osten nahe der ungarischen Grenze vor. In den 1990er-Jahren gelangen jedoch Auf- sammlungen der Art im Stidwesten des Landes in den Donauniederungen. Die nach wie vor unklare Verbreitungssituation in beiden Ldndern erschwert eine ge- naue Bestimmung des Gefiihrdungsstatus und die Formulierung geeigneter Schutz- und FdrdermaBnahmen. Da die Gefaihrdungsursachen frir die Art zu ei- nem erheblichen Teil in der Zerstorung bestehender und potenziell geeigneter Lebensrdume liegen dtirften, sollten sich Schutzbemuhungen fiir G. glabra v.a. auf diese Problematik konzentrieren. 130.11.20041 ARTICULATA 19 (2) ARTTcULATA 19 (2) [30.11.2004] Deutschen Gesellschaft für Orthopterologie e.V.; download http://www.dgfo-articulata.de/ in lntroduction cially the surroundings of the Danube river.

The studied species showed two distinct karyotypes, with 2n = 31 (male) and 2n = 23 (male) chromosomes. The drastic reduction in chromosome number observed in the latter case suggests multiple translocations and fusions as the main responsible that occurred during chromosome evolution. Two groups of rDNA distribution were found in Gampsocleis representatives analyzed.

  • Central Mechanism of Hearing in Insects
    J. Exp. Biol. (1961), 38, 545-558 ttA 5 text-figuret Printed in Great Britain CENTRAL MECHANISM OF HEARING IN INSECTS BY NOBUO SUGA AND YASUJI KATSUKI Department of Physiology, Tokyo Medical and Dental University (Received 31 January 1961) INTRODUCTION The electrical responses to sound stimuli have already been recorded from the auditory nerve bundle in several kinds of insect, in Orthoptera by Pumphrey & Rawdon- Smith (1936) and Haskell (1956, 1957), in Lepidoptera by Haskell & Belton (1956) and Roeder & Treat (1957), and in Hemiptera by Pringle (1953). The central mechanism of hearing, however, has not so far been much explored. Quite recently the present authors (Katsuki & Suga, 1958, i960) studied electrophysiologically the problems of directional sense and frequency analysis in the tympanic organ of an insect by re- cording activities of the peripheral auditory neurons. The central mechanism has been further studied, and this paper is concerned with the experimental results. Three problems have particularly been posed: frequency analysis of sound, directional sense and central inhibition. MATERIAL AND METHOD The experiments were performed on Gampsocleis buergeri (Tettigoniidae), because of its large size and ready availability. The insect was pinned on its back on a cork board and the ventral exoskeleton covering the nerve cord was removed. The tracheae distributing along the nerve cord were separated from the latter and the non-auditory inputs were also severed. The operated animal was placed about 50 cm from the loud-speakers and the sound was delivered from its left side in a sound-proofed room which was air-conditioned at about 260 C.

  • THE CURRENT STATUS of ORTHOPTEROID INSECTS in BRITAIN and IRELAND by Peter G
    THE CURRENT STATUS OF ORTHOPTEROID INSECTS IN BRITAIN AND IRELAND by Peter G. Sutton, Björn C. Beckmann & Brian Nelson INTRODUCTION This article provides an overview of the changes that have occurred within the orthopteroid fauna of Britain and Ireland since the last distribution atlas was published in 1997 (Haes & Harding, 1997). It provides the current IUCN status of the scarce and threatened species in Britain in accordance with their recent reassessment (Sutton, 2015a) and discusses the future prognosis for this group of insects in Britain and Ireland. It also highlights recent developments of the Orthoptera Recording Scheme with particular reference to the collection of distribution map data using new technologies. Changes to the orthopteroid fauna of Britain and Ireland have been assessed in the landmark publications by Ragge (1965), Marshall & Haes (1988), Haes & Harding (1997) and more recently, Benton (2012), and have also been comprehensively reviewed by Marshall (1974, 2001, 2010). In addition, a regular and ongoing summary of these changes has been provided by the Grasshoppers and Relatives section of British Wildlife magazine (Haes, 1990‒1995; Widgery 1995‒2002; Sutton, 2002‒2016), and in the Orthoptera Recording Scheme newsletters (1‒22 (Haes, 1979‒1995); 23‒28 (Widgery, 1996‒2002) and 29‒33 (Beckmann & Sutton, 2013‒2016)).

  • Molecular Evoloutionary Genetic Studies of Orthopteroid Insects
    MOLECULAR EVOLUTIONARY GENETIC STUDIES OF ORTHOPTEROID INSECTS: A BIBLIOGRAPHY. Since my last review of this topic (Chapco 1997), there has been a virtual explosion in the number of population genetics studies and phylogenetic analyses of grasshoppers, katydids and their kin in which molecular markers (e.g. RAPDs, AFLPs, microsatellites, partial mitochondrial and nuclear sequences and, more recently, complete genomic sequences) have been used as traits. To perform an up-to-date review at this time would be a somewhat daunting task. Instead, I am providing a list of references that have appeared since 1997 and which may prove useful to other researchers. The style I’ve chosen more or less follows that set out by the Journal of Orthoptera Research. Some references, strictly speaking, are not molecular in scope but ones in which comparisons with molecular phylogenetic findings are made (e.g. Cigliano and Amédégnato 2010). Others deal with molecular aspects of development (e.g. Dearden and Akam 2000), which, it is expected, will have phylogenetic implications in the future.

Orthoptera, Caelifera, Ensifera, dispersal, diversity, fl ooding, niche breadth, reproductive potential Abstract. The Tisza River Basin is an important area as it is a green corridor in which there are highly endangered habitats and a high level of biodiversity. The patterns in the species richness of invertebrates and the environmental conditions affecting these patterns are poorly studied in the grassy habitats in the lower reaches of the Tisza River Basin. The present study focuses on the effects of fl ooding, habitat and landscape features on the species richness of orthopterans at 24 grassland sites in two different landscapes. The relations between the explanatory variables and the pattern of diversity of orthopterans with different life-history traits were studied, using ordination and Generalized Linear Mixed Models. Although the infl uential factors for the different trait groups differed, we suggest that landscape features are the most important in shaping orthopteran assemblages, whereas habitat characteristics and fl ooding have comparatively little effect.

    ARTICULATA 2013 28 (1/2): 69‒90 FAUNISTIK The Orthoptera fauna of Cserhát Hills and its surroundings (North Hungary) Gergely Szövényi, Krisztián Harmos & Barnabás Nagy Abstract Cserhát is an orthopterologically relatively less studied region of the North Hun- garian Mountains. After a faunistic research conducted here, the Orthoptera fauna of the Cserhát region is summarized. The pool of formerly known 33 spe- cies is raised to 67, which is about 53% of the total Orthoptera fauna of Hungary. Seven of them (Acrida ungarica, Isophya modesta, Leptophyes discoidalis, Poly- sarcus denticauda, Poecilimon fussii, Saga pedo, Tettigonia caudata) are legally protected and two (Isophya costata, Paracaloptenus caloptenoides) strictly pro- tected in Hungary. Others (Aiolopus thalassinus, Chorthippus dichrous, Oedaleus decorus, Pachytrachis gracilis, Pezotettix giornae, Platycleis affinis, Rhacocleis germanica, Ruspolia nitidula, Tessellana veyseli) are zoogeographically also valuable here, near their northern-northwestern areal limit. Zusammenfassung Der Orthopteren-Fauna der nördlichen Mittelgebirge Ungarns ist ziemlich gut er- forscht, aber die Hügellandschaft Cserhát, in den westlichen Teil der Nördlichen Mittelgebirge, bildete bisher eine Ausnahme. Basierend auf unsere Untersuchun- gen, durchgeführt zwischen 1963 und 2011, hat sich die Artenzahl hier auf 67 erhöht (= 53% der Orthopteren-Arten Ungarns). Sieben Arten davon stehen in Ungarn unter gesetzlichem Naturschutz (Acrida ungarica, Isophya modesta, Lep- tophyes discoidalis, Polysarcus denticauda, Poecilimon fussii, Saga pedo, Tetti- gonia caudata), zwei sogar unter noch strengerem Naturschutz (Isophya costata, Paracaloptenus caloptenoides). Es gibt noch auch weitere, zoogeographisch in- teressante Arten (Aiolopus thalassinus, Chorthippus dichrous, Oedaleus deco- rus, Pachytrachis gracilis, Pezotettix giornae, Platycleis affinis, Rhacocleis germanica, Ruspolia nitidula, Tessellana veyseli), von denen manche hier am nördliche Rand ihres Verbreitungsgebiet vorkommen.

In dit netwerk formuleren onderzoekers en terreinbeheerders samen onderzoekideeën om tot concrete beheermaatregelen voor natuurherstel te komen. Nederland is een van de kleinere lidstaten van Europa. Toch heeft Nederland binnen Europa een relatief groot areaal heidelandschap en ook een belangrijke internationale verantwoordelijkheid vanwege het voorkomen van een aantal zeer bijzondere heide typen (zoals HT 2140*, HT 2310, HT 2320, HT 4010, HT 4030).
