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. -

THE MACADAMIA INDUSTRY IN NEW ZEALAND A Thesis for the Degree of Master of Philosophy At Massey University Palmerston North Bernard Coleman Whangarei 2005 ABSTRACT The New Zealand macadamia industry has been characterised by many small plantings, lifestyle blocks up to 1500 trees and two commercial plantations with more than 10000 trees. Completed research programmes have been few, mainly because government funding in horticulture has been channelled to the needs of the major crops such as kiwifruit. Changes in political policy affected funding for minor horticultural crops and spasmodic cuts in finance severely hindered long-term research projects. Because of its small size the macadamia industry had limited funds available from members but some research programmes have been completed including pest control, tree nutrition, basal stain and future research needs. A private consultant, Ian Gordon has carried out variety trials on a local selection. Several selections have been planted in different locations and have proven to be useful in pollination of Beaumont, the main variety planted in New Zealand. Within the limits, set by climatic factors, the suitable growing areas are north of a line from New Plymouth to Gisbome. Both of those areas are marginal for commercial planting but sites on the sheltered north facing positions could grow satisfactory yields. Yields per tree, generally have been below commercial requirements. -

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. -
Thaumatotibia Leucotreta
Thaumatotibia leucotreta Scientific Name Thaumatotibia leucotreta (Meyrick) Synonyms: Cryptophlebia leucotreta (Meyrick), Cryptophlebia roerigii Zacher Olethreutes leucotreta Meyrick Thaumatotibia roerigii Zacher Common Name(s) False codling moth, citrus codling moth, orange moth, and orange codling moth Type of Pest Moth Figure 1. 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). -
