CMV Infection Affects Bumblebee Pollination Behaviour and Plant Reproductive Success
Viruses can affect plant-insect interactions by altering emission of plant volatile organic compounds (VOCs). Previous work in the lab suggested that VOCs emitted by tomato (Solanum lycopersicum) plants infected with cucumber mosaic virus (CMV) were more attractive to bumblebees (Bombus terrestris) …

Behavioral Responses of Diabroticite Beetles to Selected Olfactory and Visual Cues (Coleoptera: Chrysomelidae)
… (Smith and Lawrence, 1967) for identifying host plants, and to identify interactions among these cues. Combinations of plant volatile kairomones were used to examine species differences in response to different mixtures: indole with methoxycinnamaldehyde; indole with methoxyphenethanol; and the …

Ecological and evolutionary aspects of interactions between microbes coinfecting plants
… pathogen fitness. In the research reported here, plant virus systems were used to explore the effects of coinfection on pathogen populations and host responses. Chapter 1 addresses the importance of coinfection timing using Barley yellow dwarf virus (BYDV-PAV) and Barley stripe mosaic virus. …

The application of novel mass spectrometric techniques for the analysis of volatile organic compounds in different environments
Volatile organic compounds (VOCs) are released into the atmosphere from numerous anthropogenic and biogenic sources. Traditionally VOCs have been measured using offline techniques such as Gas Chromatography-Mass Spectrometry (GC-MS). The development of the proton transfer reaction mass spectrometer …

Effects of Cucumber Mosaic Virus on Plant-Pollinator Relationships
The interactions between plants and associated insects are complex and often mediated by volatile organic chemicals (VOCs). Infection by viruses alter plant volatile signatures and consequently affect how insects interact with plants. In previous flight arena experiments in the Carr lab, cucumber …

Investigating host plant selection of harlequin bug, Murgantia histrionica (Hahn), in order to improve a trap cropping system for its management
… olfactometer choice tests, male HB responded to plant volatiles of bean, collard and mustard, but preferred Brassica volatiles over those from bean. Female response to plant volatiles alone was weak and inconsistent. Both males and females preferred volatiles from other males feeding on Brassica …
