Olivia Reynolds (née Kvedaras) is an applied ecologist 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 3-year postdoctoral fellowship in 2004 with the South African Sugarcane Research Institute and the University of Witwatersrand. 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 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, where her research interest’s centre on investigating biological forms of management of fruit fly, with particular emphasis on the Queensland fruit fly, Bactrocera tryoni Froggatt, and the role of silicon in plant-based defences at three trophic levels (plant, pest & parasitoid/predator). Olivia leads several projects, one which aims to develop a model Area Wide Management program incorporating the Sterile Insect Technique (SIT) to inform the roll-out of future campaigns.
This project is also developing an understanding of the microbial symbionts important in both domesticated and wild-collected larvae, with a view to developing a larval probiotic. Further, a molecular assay is being developed to differentiate between sterile and wild mated female flies (and sterile and wild flies), which will aid determining the success of SIT programs. Olivia is also working closely with industry (Australian Steel Mill Services) and colleagues investigating the mechanisms by which silicon application increases plant resistance to shoot and root pests via direct (e.g. mandibular wear, reduced digestibility) and indirect defence (involving natural enemy attraction via herbivore induced plant volatiles)).
Olivia also collaborates on several national and international projects, including one which is looking at developing female attractants/lures for fruit flies and one which will lead to specific management recommendations on optimal environmental conditions, release rates and release locations for sterile fruit flies. In her role as Jinshan Scholar, Olivia is working on a large international collaborative program of research investigating habitat management, biological control and genetic manipulation of insect pests of subtropical crops, as three novel strategies for ecologically based pest management in support of food security and sustainable crop production. This work will serve as a model for other pest systems. Olivia also supervises several national and international postgraduate students and postdoctoral fellows.
