Summary
Odorant recognition in insect olfactory system to control insect behaviour. This project seeks to develop new insights into insect’s ability to detect odour and to identify potential attractant compounds to support the development of environmentally safer insect pest control strategies. Insect reliance on senses to detect food has considerable potential for the development of odour-based behaviour control methods. Odorant binding proteins (OBPs) are an ideal molecular target to identify odorant- ....Odorant recognition in insect olfactory system to control insect behaviour. This project seeks to develop new insights into insect’s ability to detect odour and to identify potential attractant compounds to support the development of environmentally safer insect pest control strategies. Insect reliance on senses to detect food has considerable potential for the development of odour-based behaviour control methods. Odorant binding proteins (OBPs) are an ideal molecular target to identify odorant-based insect attractants from a large pool of compounds. However, our understanding of the molecular mechanism that mediates chemoreception in insects is limited. This project may provide valuable insight into the role of OBPs in molecular recognition in insects and develop a new way to screen attractants based on the binding ability of OBPs to compounds.Read moreRead less
Life hanging on a thread; disrupting the structure and function of lepidopteran silking behaviour. The production and use of silk by many invertebrates is vital for their survival. We develop a means of visualising and understanding the role of silking behaviour as a survival mechanism for Helicoverpa larvae (a key world-wide pest) with a view to disrupting silking. This novel project allows us to understand not just where larvae go but what they do along the way. The project outcomes will have ....Life hanging on a thread; disrupting the structure and function of lepidopteran silking behaviour.

We develop a means of visualising and understanding the role of silking behaviour as a survival mechanism for Helicoverpa larvae (a key world-wide pest) with a view to disrupting silking. This novel project allows us to understand not just where larvae go but what they do along the way. The project outcomes will have wide application to the study and control of lepidopteran pests in natural and agricultural ecosystems and is of interest to applied and fundamental projects associated with insect pest control, behaviour and ecology.Read moreRead less
Hidden Enemies of Crop Plants: Developing Novel Methods to Identify Plant Parasitic Nematodes. Plant parasitic nematodes are microscopic worms that invade roots of plants. Globally they cause annual crop losses of $2billion ($400million in Australia), making them the fourth most important plant pathogens worldwide. However, study of these pathogens has been neglected: there are few trained nematologists in Australia. There is thus a need to apply new technologies to identify nematode problems. ....Hidden Enemies of Crop Plants: Developing Novel Methods to Identify Plant Parasitic Nematodes.

However, study of these pathogens has been neglected: there are few trained nematologists in Australia. There is thus a need to apply new technologies to identify nematode problems. In this project a novel approach, that of protein profiling using mass spectroscopy, will be used to develop rapid, cost effective methods to identify nematodes. This will allow advisers and growers to identify nematode problems and so to control them appropriately.Read moreRead less
Safeguarding honeybees: understanding host-parasite interactions at the level of proteins. Parasites are responsible for dramatic declines of honeybee populations resulting in a loss of pollination services and posing a threat to food production and ecosystem stability. This project will study the honeybee immune system and its interactions with bee parasites on the molecular scale, which will be important to guide future bee breeding.
Safeguarding Honeybees: Increasing parasite treatment effectiveness using nanotechnology. There is increasing concern about the exposure of honeybees to pesticides used to control both agricultural pests and diseases. Emerging reports indicate that these chemicals substantially harm bees and therefore contribute to the dramatic declines reported. A widespread bee pathogen, Nosema, will be used to directly quantify the effectiveness of commercially used pesticides on both parasite and honeybee vi ....Safeguarding Honeybees: Increasing parasite treatment effectiveness using nanotechnology. There is increasing concern about the exposure of honeybees to pesticides used to control both agricultural pests and diseases. Emerging reports indicate that these chemicals substantially harm bees and therefore contribute to the dramatic declines reported. A widespread bee pathogen, Nosema, will be used to directly quantify the effectiveness of commercially used pesticides on both parasite and honeybee viability. Furthermore, state-of-the-art nanotechnology will be used to develop benign treatments with enhanced effectiveness and minimal dosage/exposure to the bees. Outcomes of this project can have major impact on future parasite management in commercial honeybees.Read moreRead less

Summary
Assessing pollination services of honey bees in native ecosystems and threats posed by parasites. The European honeybee is our most abundant pollinator but we know little about its role in native Australian ecosystems or how its many diseases may affect its ability to pollinate. This project will determine whether honeybees are important pollinators of native plants and how a common parasite affects their pollination ability.
