Dr Helen Nahrung has over seventeen years' experience working on pest–insect biology and ecology towards sustainable pest management methods in plantation forestry. Her research focus is primarily on insect–plant co-evolutionary interactions, including host location mechanisms and host defence.
Helen was one of the last Honours graduates from the Department of Entomology at The University of Queensland. She worked for four years on the biological control of weeds at the Alan Fletcher Research Station, and moved to Hobart in 1999 where she completed her PhD through the University of Tasmania and Cooperative Research Centre for Sustainable Production Forestry on one of the state’s most serious hardwood pests. She then undertook a postdoctoral fellowship at Queensland University of Technology, also in the field of forest entomology, and subsequently worked for six years on hardwood plantation pests with the Queensland Department of Primary Industries in the Forest Health Group. She has been at the University of the Sunshine Coast since early 2012, where she is involved in the ongoing development and conduct of empirical research towards understanding the interactions between, and developing effective management methods for, forestry pests in Queensland. Her expertise is in insect–plant interactions, but she has also worked extensively with natural enemies, development of predictive population models, and insect reproductive ecology. She is also interested in the applied use of semiochemicals/chemical ecology for pest monitoring and management.
Helen works between the USC Sippy Downs campus and the EcoSciences Precinct in Brisbane on several projects in hardwood, softwood and high-value timber plantations from Stanthorpe to the tropics, including chemical and landscape ecology, invasion characteristics, biological control, and population modelling.
