Olivia Reynolds (née Kvedaras) is a research entomologist who completed her PhD with the cotton industry on the influence of host plants on the mating behaviour of Helicoverpa armigera. After spending nearly two years travelling widely in Europe and gaining work experience after the completion of her PhD, Olivia commenced a postdoctoral fellowship in 2004 with the South African Sugarcane Research Institute and the University of Witwatersrand (Wits). Olivia's postdoctoral work with the sugarcane industry of South Africa has led to significant change in grower practice as a result of applied ecological research. Industry is now recommended to apply silicon (Si) to enhance sugarcane resistance to attack by the stem borer, Eldana saccharina Walker.
In December 2006, Olivia was appointed to NSW DPI*. Olivia is based at the Elizabeth Macarthur Agricultural Institute, and is responsible for post-production issues pertaining to fruit fly, with particular emphasis on the Queensland fruit fly, Bactrocera tryoni. Olivia leads two projects, one which aims to optimise sterile fruit fly releases for improved market access and another national project which aims to optimize a strategic trapping system to provide area-wide freedom from fruit flies. Olivia also collaborates on another two fruit fly projects, one of which is looking at developing female lures for fruit flies and one of which will lead to specific management recommendations on optimal environmental conditions, release rates and release locations for sterile fruit flies. Olivia has also continued her work with silicon (Si) based insect-plant interactions and has recently demonstrated, together with colleagues, that Si applied to plants alters the Herbivore Induced Plant Volatile profile induced when attacked by pests, making plants more attractive to natural enemies; an effect that was reflected in elevated biological control in the field. Olivia also supervises a number of postgraduate students.
*NSW Department of Primary Industries became part of the Department of Industry and Investment (Industry & Investment NSW) on July 1, 2009.
