Enhancement of plant proteinase inhibitors for the protection of crop plants against insect attack. The aim of this project is to characterise the interactions between various known plant proteinase inhibitors and the major digestive enzymes of insects by structural and dynamic studies and to utilise mutational studies to design new inhibitors that more effectively bind to target proteinases. The outcomes will be the knowledge to design specific inhibitors to give optimal inhibition of specific ....Enhancement of plant proteinase inhibitors for the protection of crop plants against insect attack. The aim of this project is to characterise the interactions between various known plant proteinase inhibitors and the major digestive enzymes of insects by structural and dynamic studies and to utilise mutational studies to design new inhibitors that more effectively bind to target proteinases. The outcomes will be the knowledge to design specific inhibitors to give optimal inhibition of specific insect proteinases. This knowledge will lead to novel approaches to protect economically important crops, such as cotton, from insect pests in Australia - potentially saving tens of millions of dollars per annum in chemical pesticide use and enhancing crop production in Australia and internationally.Read moreRead less
Development of environmentally-friendly bioinsecticides for control of Australian crop pests. Insect pests cause over $3 billion of damage each year to Australian crops. Current insecticides are becoming less effective, and they often have adverse environmental impacts. This project aims to develop a new generation of environmentally-friendly insecticides that can be used to control insect pests on farms and around the home and garden.
Benign strategies to engineer nematode resistance in plant crops. Applications to other plant pests. Control of plant pests relies on the heavy use of chemical insecticides that cause an extraordinary impact on the environment. Some insect pests have been controlled by the production of toxins (like BT) by the plant. We will combine newly discovered RNA interference and genomics methods to develop innovative solutions to nematode resistance and insect control. Our methods can be tailored to any ....Benign strategies to engineer nematode resistance in plant crops. Applications to other plant pests. Control of plant pests relies on the heavy use of chemical insecticides that cause an extraordinary impact on the environment. Some insect pests have been controlled by the production of toxins (like BT) by the plant. We will combine newly discovered RNA interference and genomics methods to develop innovative solutions to nematode resistance and insect control. Our methods can be tailored to any pest with wide or narrow spectrum of action and does not require the production of toxins by the plant. The novelty of our approach will generate a large amount of intellectual property.Read moreRead less

Be(e) friendly venomous spiders! Novel biopesticides from arachnid venoms. The overall aim of this project is to improve global honeybee health by developing novel bee-friendly bioinsecticides as well as treatments against honeybee parasites such as varroa mites and small hive beetles. This project seeks to significantly improve existing insecticidal lead peptides from spider venoms to increase their oral toxicity and make them more pest-specific. Expected outcomes of this project include a pane ....Be(e) friendly venomous spiders! Novel biopesticides from arachnid venoms. The overall aim of this project is to improve global honeybee health by developing novel bee-friendly bioinsecticides as well as treatments against honeybee parasites such as varroa mites and small hive beetles. This project seeks to significantly improve existing insecticidal lead peptides from spider venoms to increase their oral toxicity and make them more pest-specific. Expected outcomes of this project include a panel of biologically degradable venom peptides that are active against selected pest and parasite species and that can be economically produced in large scale. This would not only provide significant environmental, social and economical benefits on a global scale, but also boost the Australian agrochemical research sector.Read moreRead less
To move or not to move: are insect movement strategies driven by plant-induced defences? Plants change chemically when damaged by insects. By showing how movement and feeding is related to these induced defences we can manipulate plant defences to resist insect attack in a more focused way. Our target insects are major pests against which we use large amounts of insecticide. Our research will decrease insect damage to crops using existing genetic machinery of plants as opposed to inserting 'nove ....To move or not to move: are insect movement strategies driven by plant-induced defences? Plants change chemically when damaged by insects. By showing how movement and feeding is related to these induced defences we can manipulate plant defences to resist insect attack in a more focused way. Our target insects are major pests against which we use large amounts of insecticide. Our research will decrease insect damage to crops using existing genetic machinery of plants as opposed to inserting 'novel' toxin-expressing genes. This project builds on Australia's strong record of achievement in agricultural and natural resource research by increasing understanding of the interplay between plant traits and insects. We will build cross-disciplinary research capacity training a new generation of biologists in an exciting area of science.Read moreRead less
Novel compounds as natural herbicides for weed management. The development by weeds of herbicide resistance has undermined these systems and limited prospect for development of new chemicals with different modes of actions through traditional methods. Such methods of searching for new herbicides are yielding diminishing returns and the associated costs are becoming prohibitive.

Such methods of searching for new herbicides are yielding diminishing returns and the associated costs are becoming prohibitive.
This project aims to develop herbicides by evaluating, isolating and identifying novel natural compounds present in a range of weeds and crop plants.
The outcomes will be reduced herbicide inputs, and the development of a new group of natural herbicides to counteract the threat imposed by the development of herbicide resistance.

Does the origin of Helicoverpa punctigera populations explain their susceptibility to agricultural insecticides? By establishing the geographic origin, and migration pattens of H. punctigera populations (by gene-flow), and directly relating it to the occurrence and persistence of insecticide resistance in Australia (by describing the movement of insects with known insecticide susceptible/resistant status), this research will greatly advance our understanding of how insecticide resistance develop ....Does the origin of Helicoverpa punctigera populations explain their susceptibility to agricultural insecticides?

This knowledge will enable the agricultural industry to use insecticides so as to reduce the frequency of insecticide spray failures, and reduce crop losses caused by insecticide resistant pest outbreaks.Read moreRead less
