  • The Wing Venation of Odonata
    International Journal of Odonatology, 2019 Vol. 22, No. 1, 73–88, https://doi.org/10.1080/13887890.2019.1570876 The wing venation of Odonata John W. H. Trueman∗ and Richard J. Rowe Research School of Biology, Australian National University, Canberra, Australia (Received 28 July 2018; accepted 14 January 2019) Existing nomenclatures for the venation of the odonate wing are inconsistent and inaccurate. We offer a new scheme, based on the evolution and ontogeny of the insect wing and on the physical structure of wing veins, in which the veins of dragonflies and damselflies are fully reconciled with those of the other winged orders. Our starting point is the body of evidence that the insect pleuron and sternum are foreshortened leg segments and that wings evolved from leg appendages. We find that all expected longitudinal veins are present. The costa is a short vein, extending only to the nodus, and the entire costal field is sclerotised. The so-called double radial stem of Odonatoidea is a triple vein comprising the radial stem, the medial stem and the anterior cubitus, the radial and medial fields from the base of the wing to the arculus having closed when the basal sclerites fused to form a single axillary plate. In the distal part of the wing the medial and cubital fields are secondarily expanded. In Anisoptera the remnant anal field also is expanded. The dense crossvenation of Odonata, interpreted by some as an archedictyon, is secondary venation to support these expanded fields. The evolution of the odonate wing from the palaeopteran ancestor – first to the odonatoid condition, from there to the zygopteran wing in which a paddle-shaped blade is worked by two strong levers, and from there through grade Anisozygoptera to the anisopteran condition – can be simply explained.

  • (Pentatomidae) DISSERTATION Presented
    Genome Evolution During Development of Symbiosis in Extracellular Mutualists of Stink Bugs (Pentatomidae) DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Alejandro Otero-Bravo Graduate Program in Evolution, Ecology and Organismal Biology The Ohio State University 2020 Dissertation Committee: Zakee L. Sabree, Advisor Rachelle Adams Norman Johnson Laura Kubatko Copyrighted by Alejandro Otero-Bravo 2020 Abstract Nutritional symbioses between bacteria and insects are prevalent, diverse, and have allowed insects to expand their feeding strategies and niches. It has been well characterized that long-term insect-bacterial mutualisms cause genome reduction resulting in extremely small genomes, some even approaching sizes more similar to organelles than bacteria. While several symbioses have been described, each provides a limited view of a single or few stages of the process of reduction and the minority of these are of extracellular symbionts. This dissertation aims to address the knowledge gap in the genome evolution of extracellular insect symbionts using the stink bug – Pantoea system. Specifically, how do these symbionts genomes evolve and differ from their free- living or intracellular counterparts? In the introduction, we review the literature on extracellular symbionts of stink bugs and explore the characteristics of this system that make it valuable for the study of symbiosis. We find that stink bug symbiont genomes are very valuable for the study of genome evolution due not only to their biphasic lifestyle, but also to the degree of coevolution with their hosts. i In Chapter 1 we investigate one of the traits associated with genome reduction, high mutation rates, for Candidatus ‘Pantoea carbekii’ the symbiont of the economically important pest insect Halyomorpha halys, the brown marmorated stink bug, and evaluate its potential for elucidating host distribution, an analysis which has been successfully used with other intracellular symbionts.

GRIMALDI & KUMAR KRISHNA Abstract A brief overview and dichotomous key is provided for those termites (Isoptera) occurring in middle Eocene (Lutetian) Baltic amber. Ten species in seven genera are presently docu- mented from Baltic amber, these being as follows: Garmitermes succineus n. gen. n. sp., Ter- mopsis bremii (HEER), T. ukapirmasi n. sp., Archotermopsis tornquisti ROSEN, Proelectroter- mes berendtii (PICTET-BARABAN), Electrotermes affinis (HAGEN), E. girardi (GIEBEL), Reti- culitermes antiquus (GERMAR), R. minimus SNYDER, and Parastylotermes robustus (ROSEN). Garmitermes succineus n. gen. n. sp. is the first Mastotermes-like termite discovered in Baltic amber. Hemerobites GERMAR, a senior synonym of Reticulitermes HOLMGREN, is designated as a nomen oblitum under the ICZN rules. Maresa GIEBEL, another senior synonym of Reti- culitermes, is tentatively suppressed pending a petition to the ICZN to preserve the latter name.

  • The Mesosomal Anatomy of Myrmecia Nigrocincta Workers and Evolutionary Transformations in Formicidae (Hymeno- Ptera)

Published online at www.senckenberg.de/arthropod-systematics on May 17, 2019. Published in print on June 03, 2019. Editors in charge: Andy Sombke & Klaus-Dieter Klass. Abstract. The mesosomal skeletomuscular system of workers of Myrmecia nigrocincta was examined. A broad spectrum of methods was used, including micro-computed tomography combined with computer-based 3D reconstruction. An optimized combination of advanced techniques not only accelerates the acquisition of high quality anatomical data, but also facilitates a very detailed documentation and vi- sualization. This includes fne surface details, complex confgurations of sclerites, and also internal soft parts, for instance muscles with their precise insertion sites. Myrmeciinae have arguably retained a number of plesiomorphic mesosomal features, even though recent mo- lecular phylogenies do not place them close to the root of ants. Our mapping analyses based on previous morphological studies and recent phylogenies revealed few mesosomal apomorphies linking formicid subgroups. Only fve apomorphies were retrieved for the family, and interestingly three of them are missing in Myrmeciinae. Nevertheless, it is apparent that profound mesosomal transformations took place in the early evolution of ants, especially in the fightless workers.

Because H. undalis is difficult to control by chemical insecticides and microbiological control techniques have not been established, we investigated the biology, the pathogenicity and transmission of this pathogen found in H. undalis. An average of 16% of larvae obtained from crucifer fields in Nueva–Ecija displayed microsporidian infections and 75% of infected H. undalis died during larval development. Histopathological studies revealed that the infection is initiated in the midgut and then spreads to all organs. The microsporidium has two different sporulation sequences: a disporoblastic development pro- ducing binucleate free mature spores and an octosporoblastic development forming eight uninucleate spores. These two discrete life cycles imply its taxonomic assignment to the genus Vairimorpha. The size of the binucleate, diplokaryotic spores as measured on Giemsa-stained smears was 3:56 Æ 0:29lm in length and 2:18 Æ 0:21lm in width, whereas the uninucleate octospores measured 2:44 Æ 0:20 Â 1:64 Æ 0:14lm.

  • 1 It's All Geek to Me: Translating Names Of
    IT’S ALL GEEK TO ME: TRANSLATING NAMES OF INSECTARIUM ARTHROPODS Prof. J. Phineas Michaelson, O.M.P. U.S. Biological and Geological Survey of the Territories Central Post Office, Denver City, Colorado Territory [or Year 2016 c/o Kallima Consultants, Inc., PO Box 33084, Northglenn, CO 80233-0084] ABSTRACT Kids today! Why don’t they know the basics of Greek and Latin? Either they don’t pay attention in class, or in many cases schools just don’t teach these classic languages of science anymore. For those who are Latin and Greek-challenged, noted (fictional) Victorian entomologist and explorer, Prof. J. Phineas Michaelson, will present English translations of the scientific names that have been given to some of the popular common arthropods available for public exhibits. This paper will explore how species get their names, as well as a brief look at some of the naturalists that named them. INTRODUCTION Our education system just isn’t what it used to be. Classic languages such as Latin and Greek are no longer a part of standard curriculum. Unfortunately, this puts modern students of science at somewhat of a disadvantage compared to our predecessors when it comes to scientific names. In the insectarium world, Latin and Greek names are used for the arthropods that we display, but for most young entomologists, these words are just a challenge to pronounce and lack meaning. Working with arthropods, we all know that Entomology is the study of these animals. Sounding similar but totally different, Etymology is the study of the origin of words, and the history of word meaning.

  • Management of Sweet Potato Weevil, Cylas Formicarius: a World Review
    ® Fruit, Vegetable and Cereal Science and Biotechnology ©2012 Global Science Books Management of Sweet Potato Weevil, Cylas formicarius: A World Review Rajasekhara Rao Korada1* • Samir Kanti Naskar2 • Archana Mukherjee1 • Cheruvandasseri Arumughan Jayaprakas2 1 Regional Centre of Central Tuber Crops Research Institute, Bhubaneswar - 751 019, India 2 Central Tuber Crops Research Institute, Sreekariyam, Thiruvananthapuram - 695 017, India Corresponding author : * [email protected] ABSTRACT Sweet potato is infested by many insect pests. Sweet potato weevil (SPW) Cylas formicarius (Fab.) is the important insect pest throughout the world, wherever it is grown. The weevil is managed by a package of practices together called integrated pest management (IPM). In India, a few genotypes of sweet potato have shown durable resistance throughout 2006 to 2011. A new screening method of germplasm, volatile-assisted selection (VAS), was developed to identify resistance/susceptibility in sweet potato genotypes based on the volatile chemicals that are released. Transgenic sweet potato was not successful at the field level. Farmers in Asia practice intercropping of sweet potato with ginger, bhendi, taro and yams to reduce the incidence of pests as well as to conserve soil moisture. Entomopathogenic fungi and nematodes are used successfully to control C. formicarius in the West and Latin America. Female sex pheromone (Z)-3-dodecen-1-ol (E)-2-butenoate has changed the pest dynamics in the field and has become an important tool in C. formicarius IPM. It was used to monitor and trap male weevils, thus reducing the reproductive success of female weevils. A number of botanical pesticides are available and their use is limited in developed countries.

Sex pheromones of tropical insectsUNESCO that have been identified to– date EOLSS are mainly used for detection and population monitoring. Another strategy termed mating disruption, has been used in the control of the tomato pinworm, Keiferia lycopersicella, and the Guatemalan potato moth, Tecia solanivora. Research into other semiochemicals such as kairomones in tropical insects SAMPLErevealed evidence of their presence CHAPTERS in coleopterans. However, additional studies are necessary in order to confirm these laboratory results. In fruit flies, the isolation of potential attractants (kairomone) from Spondias mombin for Anastrepha obliqua was reported recently. The use of semiochemicals to control insect pests is advantageous in that it is safe for humans and the environment. The extensive use of these kinds of technologies could be very important in reducing the use of pesticides with the consequent reduction in the level of contamination caused by these products around the world.

  • Arthropods of Elm Fork Preserve
    Arthropods of Elm Fork Preserve Arthropods are characterized by having jointed limbs and exoskeletons. They include a diverse assortment of creatures: Insects, spiders, crustaceans (crayfish, crabs, pill bugs), centipedes and millipedes among others. Column Headings Scientific Name: The phenomenal diversity of arthropods, creates numerous difficulties in the determination of species. Positive identification is often achieved only by specialists using obscure monographs to ‘key out’ a species by examining microscopic differences in anatomy. For our purposes in this survey of the fauna, classification at a lower level of resolution still yields valuable information. For instance, knowing that ant lions belong to the Family, Myrmeleontidae, allows us to quickly look them up on the Internet and be confident we are not being fooled by a common name that may also apply to some other, unrelated something. With the Family name firmly in hand, we may explore the natural history of ant lions without needing to know exactly which species we are viewing. In some instances identification is only readily available at an even higher ranking such as Class. Millipedes are in the Class Diplopoda. There are many Orders (O) of millipedes and they are not easily differentiated so this entry is best left at the rank of Class. A great deal of taxonomic reorganization has been occurring lately with advances in DNA analysis pointing out underlying connections and differences that were previously unrealized. For this reason, all other rankings aside from Family, Genus and Species have been omitted from the interior of the tables since many of these ranks are in a state of flux.
