Plant volatile compounds are involved in a range of ecological interactions. I study the role of these chemicals in plant-insect and plant-plant interactions and how this knowledge can be applied to the develop- ment of sustainable crop protection strategies.
I study the role of plant volatile organic compounds in signalling within and between plants and between plants and insects. My research aims to enhance the capacity of plants to resist attack by aphid pests, by exploiting chemical signalling between the plants themselves, between plants and aphids, and between plants and aphid natural enemies in order to develop new, more sustainable solutions to aphid control in cereals, primarily barley. Aphids are phloem-feeding insects that are able both to induce and suppress plant defensive response. I study how plant volatile chemicals influence the behaviour of aphids and their natural enemies and how different aspects of aphid behaviour and ecology affect the induction of volatiles in plants.
I study the effects of plant-plant chemical communication on the natural enemies of aphids, primarily ladybirds and parasitic wasps, and investigate tritrophic interactions in mixed genotype cropping.
I work with the volatile chemistry of crop plants, collecting and identifying the volatile blends released by the plants and investigating how they mediate interactions between plants and between plants and insects. The ultimate goals are to discover new ways to manipulate induced resistance against pests and diseases in crop plants, and to design new cropping systems that more effectively use the indirect defence provided by natural enemies.
