SCARAB : development of a rugged, low cost, inspection-class robotic platform
This dissertation details the design and development of a prototype of a new robotic platform designed to carry a variety of sensors into environments that are too dangerous or confined for human workers, and forms part of a series of three concurrent M.Sc(Eng) dissertations which will integrate …

Parasitism of Scarabaeidae by Parasitoid Flies in British Columbia and Western USA: Informing Biological Control Programs Against Popillia japonica with Crowd-sourced Records of Non-target Scarab Beetles
… to suppress a population of the invasive scarab beetle Popillia japonica, I used crowd-sourced online data (44,200 observations in BC and Western USA) to determine: scarab species occurrence; which species may be attacked by parasitoid flies; whether any bore eggs that resemble I. …

Tropical Pyramids: Dung Beetle Richness, Abundance, and Biomass
… (P < 0.0001) and 12 Neotropical genera of scarabs, of which 11 were highly significant. The effect of short term (< 1 year) alcohol storage on volume was negligable. I found scarab volume on geologically old soils in the Amazon was one-third that of the geologically young Amazon (P < …

Design of the communication, power management and interchangeable sensor payload system for an inspection-class robotic platform
… a platform to fulfil this requirement, with the Scarab (Figure 0-1) - a low-cost, man-packable, throwable inspection-class robotic platform with interchangeable payloads. The system was designed to create a 1:1 human-to-robot ratio which improves the efficiency of rescue operations. Once the …

Design of a man-wearable control station for a robotic rescue system
… Rescue (USAR). The complete system, dubbed the "Scarab", is the 1st generation developed and built in the Robotics and Agents Research Laboratory (RARL) at the University of Cape Town (UCT), and was a joint effort between three MSc students. Robots have found a place in USAR as replaceable units …

Discovery and Phylogeny of the Odorant Binding and Chemosensory Proteins of Diabrotica Virgifera Virgifera (Coleoptera: Chrysomelidae) and Rhagoletis (Diptera: Tephritidae)
… except that OBP 1 is a putative orthologue of scarab pheromone-binding proteins. Nine OBPs and two CSPs were recovered from R. suavis; all are putative orthologues of Drosophila melanogaster proteins. Two R. suavis OBPs, KAR and SAR, were used to investigate the phylogeny of the R. pomonella …

Micro- and nanoscale features of insect cuticle and their impacts on wetting, friction, and optical properties
… were examined in carabid, staphylinid, and scarab beetles. No differences were found in the ability to match the color of various substrates or to linearly polarize light between iridescent and noniridescent beetles. The ability for diffraction gratings to modify cuticle wettability varied …

Aspects of the root ecology of Neotyphodium endophytes in Lolium perenne
… or survival of root-feeding larvae of the scarab Costelytra zealandica. Endophyte infection had no discernible adverse effects on populations of Collembola, oribatid mites or dorylaimid nematodes. Higher root aphid populations were associated with higher populations of Collembola and lower …

Molecular Systematics of the Entomopathogenic Bacteria Bacillus popilliae, Bacillus lentimorbus, and Bacillus sphaericus
… of milky disease in Japanese beetles and related scarab larvae, have been differentiated based upon a small number of phenotypic characteristics, but they have not previously been examined at the molecular level. Thirty-four isolates of these bacteria were examined for DNA similarity. Three …

A taxonomic study of Sorocephalus and Spatalla
… were the most important pollen vectors. Certain Scarab beetles, particularly Anisonyx ursus and. Trichostetha spp. · were found to play a significant but less important role in pollen transfer due to their short seasonal activity. Phytogeographic studies showed that although the distribution …
