  • Duration of Development and Number of Nymphal Instars Are Differentially Regulated by Photoperiod in the Cricketmodicogryllus Siamensis (Orthoptera: Gryllidae)
    Eur. J.Entomol. 100: 275-281, 2003 ISSN 1210-5759 Duration of development and number of nymphal instars are differentially regulated by photoperiod in the cricketModicogryllus siamensis (Orthoptera: Gryllidae) No r ic h ik a TANIGUCHI and Ke n ji TOMIOKA* Department ofPhysics, Biology and Informatics, Faculty of Science and Research Institute for Time Studies, Yamaguchi University 753-8512, Japan Key words. Photoperiod, nymphal development, cricket,Modicogryllus siamensis Abstract. The effect of photoperiod on nymphal development in the cricketModicogryllus siamensis was studied. In constant long- days with 16 hr light at 25°C, nymphs matured within 40 days undergoing 7 moults, while in constant short-days with 12 hr light, 12~23 weeks and 11 or more moults were necessary for nymphal development. When nymphs were transferred from long to short day conditions in the 2nd instar, both the number of nymphal instars and the nymphal duration increased. However, only the nym­ phal duration increased when transferred to short day conditions in the 3rd instar or later. When the reciprocal transfer was made, the accelerating effect of long-days was less pronounced. The earlier the transfer was made, the fewer the nymphal instars and the shorter the nymphal duration. The decelerating effect of short-days or accelerating effect of long-days on nymphal development varied depending on instar. These results suggest that the photoperiod differentially controls the number of nymphal instars and the duration of each instar, and that the stage most important for the photoperiodic response is the 2nd instar. INTRODUCTION reversed (Masaki & Sugahara, 1992). However, the Most insects in temperate zones have life cycles highlymechanism by which photoperiod controls the nymphal adapted to seasonal change.

Orthoptera, cricket, grasshopper, community ecology, disturbance, grassland, woodland zone, Lazovsky Reserve, Russian Far East, habitat heterogeneity, habitat specifity, Palaearctic Abstract. We investigate orthopteran communities in the natural landscape of the Russian Far East and compare the habitat require- ments of the species with those of the same or closely related species found in the largely agricultural landscape of central Europe. The study area is the 1,200 km2 Lazovsky State Nature Reserve (Primorsky region, southern Russian Far East) 200 km east of Vladi- vostok in the southern spurs of the Sikhote-Alin Mountains (134°E/43°N). The abundance of Orthoptera was recorded in August and September 2001 based on the number present in 20 randomly placed 1 m² quadrates per site. For each plot (i) the number of species of Orthoptera, (ii) absolute species abundance and (iii) fifteen environmental parameters characterising habitat structure and micro- climate were recorded. Canonical correspondence analysis (CCA) was used first to determine whether the Orthoptera occur in ecol- ogically coherent groups, and second, to assess their association with habitat characteristics. In addition, the number of species and individuals in natural and semi-natural habitats were compared using a t test.

  • Phylogeny of Ensifera (Hexapoda: Orthoptera) Using Three Ribosomal Loci, with Implications for the Evolution of Acoustic Communication
    Molecular Phylogenetics and Evolution 38 (2006) 510–530 www.elsevier.com/locate/ympev Phylogeny of Ensifera (Hexapoda: Orthoptera) using three ribosomal loci, with implications for the evolution of acoustic communication M.C. Jost a,*, K.L. Shaw b a Department of Organismic and Evolutionary Biology, Harvard University, USA b Department of Biology, University of Maryland, College Park, MD, USA Received 9 May 2005; revised 27 September 2005; accepted 4 October 2005 Available online 16 November 2005 Abstract Representatives of the Orthopteran suborder Ensifera (crickets, katydids, and related insects) are well known for acoustic signals pro- duced in the contexts of courtship and mate recognition. We present a phylogenetic estimate of Ensifera for a sample of 51 taxonomically diverse exemplars, using sequences from 18S, 28S, and 16S rRNA. The results support a monophyletic Ensifera, monophyly of most ensiferan families, and the superfamily Gryllacridoidea which would include Stenopelmatidae, Anostostomatidae, Gryllacrididae, and Lezina. Schizodactylidae was recovered as the sister lineage to Grylloidea, and both Rhaphidophoridae and Tettigoniidae were found to be more closely related to Grylloidea than has been suggested by prior studies. The ambidextrously stridulating haglid Cyphoderris was found to be basal (or sister) to a clade that contains both Grylloidea and Tettigoniidae. Tree comparison tests with the concatenated molecular data found our phylogeny to be significantly better at explaining our data than three recent phylogenetic hypotheses based on morphological characters. A high degree of conflict exists between the molecular and morphological data, possibly indicating that much homoplasy is present in Ensifera, particularly in acoustic structures. In contrast to prior evolutionary hypotheses based on most parsi- monious ancestral state reconstructions, we propose that tegminal stridulation and tibial tympana are ancestral to Ensifera and were lost multiple times, especially within the Gryllidae.

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000).

  • Two New Species of the Genus Scottiola Uvarov (Orthoptera: Gryllidae: Nemobiinae) from Pakistan
    INT. K. BIOL. BIOTECH., 6 (3): 103-108, 2009. TWO NEW SPECIES OF THE GENUS SCOTTIOLA UVAROV (ORTHOPTERA: GRYLLIDAE: NEMOBIINAE) FROM PAKISTAN Nasreen Khan and Syed Kamaluddin Department of Zoology, Federal Urdu University of Arts, Science and technology, Gulshan-E-Iqbal Campus, University Road Karachi-75400, Pakistan. ABSTRACT Two new species of the genus Scottiola Uvarov are described to accommodating one already described species in detail with reference to their genital components. A key to the Pakistani species is formulated and the cladistic relationship of included texa is also discussed by using their apomorphies. Key words: New species, Scottiola, Orthoptera, Gryllidae, Pakistan. INTRODUCTION The representatives of the genus Scottiola of sub family Nemobiinae are distributed mostly in tropical region. Both sexes of the genus are apterous. Chopard (1969) described the fauna of India and adjacent countries in which he discussed from Pakistan on the basis of their external morphology. Quayyoom et al. (1987) worked on the phonetic approach to the taxonomy of Gryllidae of Faisalabad on generic level. Sinzo (1978) also discussed climatic adaptation and species status in the lawn ground cricket. Hinton (1949) described the common insect, pests of stored food products. Kamaluddin and Khan (2005) described three new species of the genus Pteronemobius from Pakistan and Khan and Kamaluddin (2006) discussed the detailed morphology of Pteronemobius indicus Walker of the sub family Nemobiinae. MATERIALS AND MATHODS A few specimens were collected from grasslands of Thatta; Sindh by the sweeping technique from insects net and with the help of light trap, later identified with the help of Chopard (1969) and other collected literature.

We propose the first phylogenetic hypothesis for the evolu- tion of crickets sensu lato, based on analysis of 205 species, representing 88% of the subfamilies and 71% tribes currently listed in the database Orthoptera Species File (OSF). We reconstructed parsimony, maximum likelihood and Bayesian phylogenies using fragments of 18S, 28SA, 28SD, H3, 12S, 16S, and cytb (~3600 bp). Our results support the monophyly of the cricket clade, and its subdivision into two clades: mole crickets and ant-loving crickets on the one hand, and all the other crickets on the other (i.e. crickets sensu stricto). Crickets sensu stricto form seven monophyletic clades, which support part of the OSF fami- lies, “subfamily groups”, or subfamilies: the mole crickets (OSF Gryllotalpidae), the scaly crickets (OSF Mogoplistidae), and the true crickets (OSF Gryllidae) are recovered as monophyletic.
