The Isolation and Genetic Characterisation of a Novel Alphabaculovirus for the Microbial Control of Cryptophlebia Peltastica and Closely Related Tortricid Pests
RHODES UNIVERSITY Where leaders learn The isolation and genetic characterisation of a novel alphabaculovirus for the microbial control of Cryptophlebia peltastica and closely related tortricid pests Submitted in fulfilment of the requirements for the degree of DOCTOR OF PHILOSOPHY At RHODES UNIVERSITY By TAMRYN MARSBERG December 2016 ABSTRACT Cryptophlebia peltastica (Meyrick) (Lepidoptera: Tortricidae) is an economically damaging pest of litchis and macadamias in South Africa. Cryptophlebia peltastica causes both pre- and post-harvest damage to litchis, reducing overall yields and thus classifying the pest as a phytosanitary risk. Various control methods have been implemented against C. peltastica in an integrated pest management programme. These control methods include chemical control, cultural control and biological control. However, these methods have not yet provided satisfactory control as of yet. As a result, an alternative control option needs to be identified and implemented into the IPM programme. An alternative method of control that has proved successful in other agricultural sectors and not yet implemented in the control of C. peltastica is that of microbial control, specifically the use of baculovirus biopesticides. This study aimed to isolate and characterise a novel baculovirus from a laboratory culture of C. peltastica that could be used as a commercially available baculovirus biopesticide. In order to isolate a baculovirus a laboratory culture of C. peltastica was successfully established at Rhodes University, Grahamstown, South Africa. This is the first time a laboratory culture of C. peltastica has been established. This allowed for various biological aspects of the pest to be determined, which included: length of the life cycle, fecundity and time to oviposition, egg and larval development and percentage hatch. -

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. -

Larva of Thaumatotibia leucotreta (T. Grove Taxonomic Position and W. Styn, bugwood.org). Class: Insecta, Order: Lepidoptera, Family: Tortricidae Reason for Inclusion CAPS Target: AHP Prioritized Pest List - 2003 through 2014 Pest Description Eggs: Eggs are flat, oval (0.77 mm long by 0.60 mm wide) shaped discs with a granulated surface. The eggs are white to cream colored when initially laid. They change to a reddish color before the black head capsule of the larvae becomes visible under the chorion prior to hatching (Daiber, 1979a). 1 Larvae: First instar (neonate) larvae approximately 1 to 1.2 mm (< /16 in) in length with dark pinacula giving a spotted appearance, fifth instar larvae are orangey-pink, 1 becoming more pale on sides and yellow in ventral region, 12 to 18 mm (approx. /2 to 11 /16 in) long, with a brown head capsule and prothoracic shield (Fig. 1). [Note this coloration is only present in live specimens.] The last abdominal segment bears an anal comb with two to ten “teeth.” The mean head capsule width for the first through fifth instar larvae has been recorded as: 0.22, 0.37, 0.61, 0.94 and 1.37 mm, respectively (Daiber, 1979b). Diagnostic characters would include the anal comb with two to ten teeth in addition to: L pinaculum on T1 enlarged and extending beneath and beyond (posterad of) the spiracle; spiracle on A8 displaced posterad of SD pinaculum; crochets unevenly triordinal, 36-42; L-group on A9 usually trisetose (all setae usually on same pinaulum) (Brown, 2011). -
Probing the Physics of Narrow Line Regions in Active Galaxies II: the Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7)
Probing the Physics of Narrow Line Regions in Active Galaxies II: The Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7) Michael A.

Ramya 3, Chichuan Jin6, Julie Banfield7, Ingyin Zaw8, St´ephanie Juneau9, Bethan James10 & Shweta Srivastava11 [email protected] ABSTRACT Here we describe the Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7) and present results on 64 galaxies drawn from the first data release. The S7 uses the Wide Field Spectrograph (WiFeS) mounted on the ANU 2.3m telescope located at the Siding Spring Observatory to deliver an integral field of 38×25 arcsec at a spectral resolution of R = 7000 in the red (530−710nm), and R = 3000 in the blue (340 − 560nm). From these data cubes we have extracted the Narrow Line Region (NLR) spectra from a 4 arc sec aperture centred on the nucleus. We also determine the Hβ and [O III] λ5007 fluxes in the narrow lines, the nuclear reddening, the reddening-corrected relative intensities of the observed emission lines, and the Hβ and [O III] λ5007 luminosities determined 1RSAA, Australian National University, Cotter Road, Weston Creek, ACT 2611, Australia 2Astronomy Department, King Abdulaziz University, P.O.

Integral Field Unit Spectroscopy of 10 Early Type Galactic Nuclei: I-Principal
Mon. Not. R. Astron. Soc. 000, 1–?? (2002) Printed 10 October 2018 (MN LaTEX style file v2.2) Integral field unit spectroscopy of 10 early type galactic nuclei: I - Principal component analysis Tomography and nuclear activity T.V. Ricci,1? J.E. Steiner,1 R.B. Menezes1 1Instituto de Astronomia, Geofísica e Ciências Atmosféricas, Universidade de São Paulo, 05508-900, São Paulo, Brazil Released 2002 Xxxxx XX ABSTRACT Most massive galaxies show emission lines that can be characterized as LINERs. To what extent this emission is related to AGNs or to stellar processes is still an open question. In this paper, we analysed a sample of such galaxies to study the central re- gion in terms of nuclear and circumnuclear emission lines, as well as the stellar compo- nent properties. For this reason, we selected 10 massive (σ >200 km s−1) nearby (d < 31 Mpc) galaxies and observed them with the IFU/GMOS (integral field unit/Gemini Multi-Object Spectrograph) spectrograph on the Gemini South Telescope. The data were analysed with principal component analysis (PCA) Tomography to assess the main properties of the objects. Two spectral regions were analysed: a yellow region (5100-5800 Å), adequate to show the properties of the stellar component, and a red region (6250-6800 Å), adequate to analyse the gaseous component. We found that all objects previously known to present emission lines have a central AGN-type emitting source. They also show gaseous and stellar kinematics typical of discs. Such discs may be co-aligned (NGC 1380 and ESO 208 G-21), in counter-rotation (IC 1459 and NGC 7097) or misaligned (IC 5181 and NGC 4546). -

If unopposed by a heating mechanism, the gas will radiatively 4 À1 cool to temperatures P10 K at a rate proportional to LX /TX , typically 0.03–1 M yr . We can test whether gas is cooling through the 3 ; 105 K range by observing the O vi doublet, whose luminosity is proportional to the cooling rate. -
