(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. -

A new genus and species, Yuripopovina magnifica, belonging to a new coreoid family, Yuripopovinidae (Hemiptera: Pentatomomorpha), is described and illustrated from the Lower Cretaceous amber of Lebanon. The species represents the first definitive Mesozoic record for the Coreoidea. A cladistic analysis of Coreoidea, including the new family, is undertaken. KEY WORDS: Pentatomomorpha, Coreoidea, Yuripopovinidae, fam. n., gen. n., sp. n., Lebanon, phylogeny. INTRODUCTION The Pentatomomorpha with its 14 000 known living species (WEIRAUCH & SCHUH 2011) is the second largest of the seven heteropteran infraorders (SCHAEFER 1993, ŠTYS & KERZHNER 1975) (Enicocephalomorpha, Dipsocoromorpha, Gerromorpha, Nepomorpha, Leptodomorpha, Cimicomorpha, and Pentatomorpha). Most authors recognize five superfamilies within Pentatomomorpha, but there remains controversy regarding the 628 Polish Journal of Entomology 80 (4) composition of these superfamilies (SCHAEFER 1993, ŠTYS 1961). -
Senecio Brasiliensis E Alcaloides Pirrolizidínicos: Toxicidade Em Animais E Na Saúde Humana

Nesse contexto, no Rio Grande do Sul, o gênero Senecio, especialmente S. brasiliensis Lessing, merece maior destaque por ser a principal causa de mortes de bovinos adultos. A toxicidade causada por esse gênero vegetal ocorre devido à presença dos alcaloides pirrolizidínicos, os quais sofrem biotransformação no fígado, gerando metabólitos tóxicos: os pirrois. Esses compostos tóxicos podem também ser nocivos para o homem através do consumo de produtos comestíveis, de origem animal, contaminados ou pelo uso dessa planta na medicina popular. Assim, o presente artigo traz uma revisão, em particular de S. brasiliensis com ênfase nos seus princípios ativos tóxicos e no mecanismo pelo qual se desenvolve a patogenia, além de abordar outras plantas que contêm os mesmos princípios tóxicos e que causam efeitos nocivos à saúde humana.

TRICEROMYCES: WITH A DESCRIPTION OF MONOECIOUS-DIOECIOUS DIMORPHISM IN THE GENUS RICHARD K. BENJAMIN Rancho Santa Ana Botanic Garden Claremont, California 91711 ABSTRACf Six species of Triceromyces (Laboulbeniales), including the type, T. balazucii (on Hebridae), parasitic on semiaquatic Hemiptera, were studied at the light-microscopic level. Descriptions are provided for all of the taxa, and features of developmental morphology are described, compared, and illustrated with photographs and line drawings. Four species are described as new: T. hebri (on Hebridae), T. hydrometrae (on Hydrometridae), and T. bi/ormis and T. bullatus (on MesoveJiidae). The species growing on Hebridae and Hydrometridae are monoecious. The two species on Mesoveliidae develop monoecious and dioecious morphs, which occur together on the same host individual. This phenom enon is recognized and described for the first time in the Laboulbeniales. Two species, Autophagomyces poissonii and Dioicomyces mesoveliae, previously described from a species ofMesoveliidae, are shown to represent the monoecious and dioecious forms of a species of Triceromyces and are transferred to this genus as T. -

Acta Musei Moraviae, Scientiae biologicae (Brno) 95(2): 11–18. – The following new or confirmed records of West and Central Palaearctic Hebridae are given: Hebrus kiritshenkoi Kanyukova, 1997 from Afghanistan, Hebrus montanus Kolenati, 1857 from Greece, Jordan, Lebanon, and Morocco, Hebrus pilipes Kanyukova, 1997 from Afghanistan, and Hebrus oxianus Kanyukova, 1997 from Afghanistan and Iran. The records from Afghanistan are the first representatives of the family Hebridae from this country. Keywords. Heteroptera, Hebridae, Hebrus, faunistics, Afghanistan, Azerbaijan, Greece, Iran, Jordan, Lebanon, Morocco, Uzbekistan, Palaearctic Region Introduction The velvet water bugs or sphagnum bugs, family Hebridae, make up one of the basal groups of the infraorder Gerromorpha (DAMGAARD 2008). These small bugs (1.3–3.7 mm) are predatory on small arthropods. Primarily terrestrial, the bugs inhabit moist microhabitats on the banks of bodies of water (humid litter, moss), and marginal aquatic habitats (sphagnum bogs, sedge marshes), while some tropical representatives live on the surface of water covered with floating plants, sometimes entering the water; the Oriental genus Nieserius Zettel, 1999 is obligatorily subaquatic. -

Pyrrhocoris Apterus L. (Hemiptera: Pyrrhocoridae), a Newly Introduced Family, Genus, and Species to Ontario and Canada
Pyrrhocoris apterus , newly introduced to Ontario and Canada JESO Volume 149, 2018 PYRRHOCORIS APTERUS L. (HEMIPTERA: PYRRHOCORIDAE), A NEWLY INTRODUCED FAMILY, GENUS, AND SPECIES TO ONTARIO AND CANADA P. J. OVIEDO RojAS1* AND M. D. JACKsoN1 1University of Guelph: 50 Stone Road East, Guelph, Ontario, Canada N1G 2W1 email, [email protected] Scientific Note J. ent. Soc. Ont. 149: 27–32 The family Pyrrhocoridae (Hemiptera: Pentatomomorpha) has a widespread range, having its greatest diversity in the tropics yet also containing members endemic to the Holarctic region (Schuh and Slater 1995), although none are native to Canada. Dysdercus Guérin-Méneville (Hemiptera: Pyrrhocoridae), which includes the economically important cotton stainers, is the only pyrrhocorid genus with members native to the New World, but is chiefly tropical and more diverse in the Old World (Schaefer 2015). One species has been recorded from as far north as South Carolina and Georgia, USA (Henry 1988a). Pyrrhocoris apterus L. (Hemiptera: Pyrrhocoridae), commonly known as the European firebug, linden bug, or red soldier bug, is found natively throughout Europe and neighbouring regions of Asia. Pyrrhocoris apterus has also been recorded historically from Costa Rica (Distant 1880–1893) and reported in New Jersey, USA in 1896 (Barber 1911; Henry 1988a), though it was not considered established in North America until it was found in Utah, USA in 2008 (Hodgson 2008). This paper will describe the first account of P. apterus, and the family Pyrrhocoridae, in Canada, with evidence that the species has become locally established. The first author first noticed P. apterus in a backyard in Etobicoke, Ontario near the intersection of Martin Grove Road and The Westway (43°41’N 79°34’W) in August 2017.
