    Characterization of Autographa californica nucleopolyhedrovirus immediate early protein ME53: The role of conserved domains in BV production, viral gene transcription, and evidence for ME53 presence at the ribosome by Robyn Ralph A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Master of Science in Molecular and Cellular Biology Guelph, Ontario, Canada © Robyn Ralph, December, 2018 ABSTRACT CHARACTERIZATION OF AUTOGRAPHA CALIFORNICA NUCLEOPOLYHEDROVIRUS IMMEDIATE EARLY PROTEIN ME53: THE ROLE OF CONSERVED DOMAINS IN BV PRODUCTION, VIRAL GENE TRANSCRIPTION, AND EVIDENCE FOR ME53 PRESENCE AT THE RIBOSOME Robyn Ralph Advisors: University of Guelph, 2018 Dr. Peter Krell Dr. Sarah Wooton The baculovirus AcMNPV early/late gene me53 is required for efficient BV production and is conserved in all alpha and betabaculoviruses. The 449-amino acid protein contains several highly conserved functionally important domains including two putative C4 zinc finger domains (ZnF-N and ZnF-C) whose cysteine residues are 100% conserved. One purpose of this study is to confirm the presence of two zinc binding domains in ME53, as well as determine their role in virus infection and viral gene transcription. Interestingly, deletion of ZnF-C results in an early delay of BV production from 12 to 18 hours post transfection correlating to ME53's cytoplasmic localization. Cytoplasmic functions at early times post-transfection may include translational regulation, which is supported by yeast-2-hybrid data that ME53 interacts with the host 40S ribosomal subunit protein RACK1. In this study the association of ME53 with the ribosomes of virus infected cells was also investigated. iii DEDICATION I dedicate this thesis to my father, Ronald James Ralph.

    ACTA AMAZONICA http://dx.doi.org/10.1590/1809-4392201704721 ORIGINAL ARTICLE Diversity patterns of hawkmoths (Lepidoptera: Sphingidae) in the canopy of an ombrophilous forest in the central Amazon, Brazil Gilcélia Melo LOURIDO1*, Catarina da Silva MOTTA†, Márlon Breno GRAÇA1, José Albertino RAFAEL1 1 Instituto Nacional de Pesquisas da Amazônia (INPA), Coordenação de Biodiversidade (COBIO), Manaus, Amazonas, Brasil † In memoriam * Corresponding author: [email protected] ABSTRACT Sphingidae attracted to light were systematically collected in an Amazonian forest canopy. Sampling occurred at a height of 34 m in an upland primary rainforest plateau in the Cueiras River basin, located within the Experimental Station of Tropical Silviculture, Manaus municipality, Amazonas, Brazil. The hawkmoths were collected using a vertical white sheet illuminated by a 250 W mixed mercury light and a 20 W black-light (BLB) fluorescent tube. Monthly collections were carried out from January to December 2004, during three nights of lunar transition from third quarter moon to new moon between 6 p.m. and 6 a.m. We sampled 1748 specimens, represented by 1485 males and 263 females, belonging to 52 species and 21 genera. Xylophanes comprised the highest number of species (seven), followed by Erinnyis, with six species. The most abundant species were Pseudosphinx tetrio (169 specimens), Pachylia darceta (162), Erinnyis ello ello (154), Isognathus excelsior (151) and Callionima parce (139). The species accumulation curve showed that the species richness tended to stabilize by the eighth month. We also observed that species composition altered significantly throughout the night period. All presented hawkmoth records are new for the canopy in the central Amazon.

In the 1990s, the Dione juno nucleopolyhedrovirus (DijuNPV) was isolated from larvae of the major passionfruit defoliator pest Dione juno juno (Nymphalidae) and described at ultrastructural and pathological levels. In this study, the complete genome sequence of DijuNPV was determined and analyzed. The circular genome presents 122,075 bp with a G + C content of 50.9%. DijuNPV is the first alphabaculovirus completely sequenced that was isolated from a nymphalid host and may represent a divergent species. It appeared closely related to Orgyia pseudotsugata multiple nucleopolyhedrovirus (OpMNPV) and other Choristoneura-isolated group I alphabaculoviruses. We annotated 153 open reading frames (ORFs), including a set of 38 core genes, 26 ORFs identified as present in lepidopteran baculoviruses, 17 ORFs unique in baculovirus, and several auxiliary genes (e.g., bro, cathepsin, chitinase, iap-1, iap-2, and thymidylate kinase).

  • Insects Associated with Guettarda Scabra in Everglades National Park, Florida
    CASTANEA 85(1): 155–158 April Copyright 2020 Southern Appalachian Botanical Society Scientific Note: Insects associated with Guettarda scabra in Everglades National Park, Florida Suzanne Koptur Florida International University, Department of Biological Sciences, Miami, FL 33199 ABSTRACT Guettarda scabra leaves are consumed by a variety of moth caterpillars, some with adults that visit the flowers and may serve as pollinators. Flower-opening is hastened by eager flower-flies, and during the night the flowers are visited by hawk moths (Sphingidae); in the morning they are visited by butterflies. Key words: butterflies, floral visitors, flower flies, herbivores, moths, pine rocklands, pollinators, velvetseed In pine rocklands of the Everglades, one of the most abundant and conspicuous woody plants is the rough-leaved velvetseed, Guettarda scabra (L.) Vent. (Rubiaceae). Though plants reach reproductive size at 1 m or less in height, they can grow to 6 m in hardwood hammocks (Koptur and Garcia 2017). Pine rockland G. scabra plants bear many leaves that mature to be tough and small in the bright sun of the pine rockland, whereas their counterparts in hammocks produce fewer leaves that are larger and softer (Koptur and Garcia 2017.). The plants are deciduous, and most individuals spend a month or more leafless, though some retain their old leaves while producing new leaves, then dropping the older ones (Koptur unpublished data). The species was categorized as “tropical summer- flowering” (Tomlinson 1980), and plants in Everglades National Park begin blooming in late May, with the last individuals finishing flowering in July; peak flowering is in June (Loope 1980, Gunderson et al.

  • The Characterisation of a Nucleopolyhedrovirus Infecting the Insect Trichoplusia Ni
    The characterisation of a nucleopolyhedrovirus infecting the insect Trichoplusia ni by Michael Tobin Thesis submitted in fulfilment of the requirements for the degree Master of Science in Biomedical Sciences In the Faculty of Health and Wellness Sciences at the Cape Peninsula University of Technology Supervisor: Prof Sehaam Khan Co-supervisor: Prof Wesaal Khan Bellville January 2019 CPUT copyright information The dissertation/thesis may not be published either in part (in scholarly, scientific or technical journals), or as a whole (as a monograph), unless permission has been obtained from the University i DECLARATION I, Michael Tobin, declare that the contents of this dissertation/thesis represent my own unaided work, and that the dissertation/thesis has not previously been submitted for academic examination towards any qualification. Furthermore, it represents my own opinions and not necessarily those of the Cape Peninsula University of Technology. Signed Date ii ABSTRACT Background: Baculoviruses have great potential as alternatives to conventional chemical insecticides. The large scale adoption of such agents has however been hampered by the slow killing times exhibited by these bio-insecticides, limitation to single target insect and difficulty of large scale production of these preparations. Trichoplusia ni single nucleopolyhedrovirus (TnSNPV), initially identified in the Eastern Cape region of South Africa, has potential as a biocontrol agent as it possesses a higher speed of kill compared to other baculoviruses. Aims and methods: The main objective of this study was the identification, molecular characterisation and cloning of a structural core gene (polyhedrin) and three auxiliary genes, the inhibitor of apoptosis (iap2 and iap3) and the ecdysteroid UDP-glucosyltransferase (egt) genes, from TnSNPV in order to delineate its phylogenetic relationship to a Canadian isolate of the same virus and to other baculoviruses.
