Development of environmentally-friendly insecticides for the Australian livestock industry. Many insects and other arthropods are serious pests of Australian livestock. Australian farmers spend about $300 million per annum on insecticides and acaricides, while Australian consumers spend more than $100 million annually on insecticides for use on pets and around the home and garden. Unfortunately, many of these arthropod pests have developed resistance to chemical insecticides. This aim of this re ....Development of environmentally-friendly insecticides for the Australian livestock industry. Many insects and other arthropods are serious pests of Australian livestock. Australian farmers spend about $300 million per annum on insecticides and acaricides, while Australian consumers spend more than $100 million annually on insecticides for use on pets and around the home and garden. Unfortunately, many of these arthropod pests have developed resistance to chemical insecticides. This aim of this research program is to develop a new generation of environmentally-friendly natural products that can be used to control arthropod pests on farms and around the home and garden.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.
Development of Novel Pesticidal Agents. We have discovered a family of naturally occurring plant proteins called the cyclotides that have potent insecticidal activity against Helicoverpa species, one of the major pests on cotton and corn in Australia and world wide. Preliminary evidence has shown that they also have activity against major pests to livestock in Australia, including sheep blowflies. To develop these proteins as potential pesticidal agents it is necessary to understand the struct ....Development of Novel Pesticidal Agents. We have discovered a family of naturally occurring plant proteins called the cyclotides that have potent insecticidal activity against Helicoverpa species, one of the major pests on cotton and corn in Australia and world wide. Preliminary evidence has shown that they also have activity against major pests to livestock in Australia, including sheep blowflies. To develop these proteins as potential pesticidal agents it is necessary to understand the structural basis for their activity. We will do this by chemically synthesising peptides with selected residues mutated to determine their effects on activity.Read moreRead less
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? 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 develops and how it spreads. 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
Cell-free immune reactions and suppression. Insects pests and insect vectors of diseases are managed by toxic substances, but insects have a cunning ability to persist. How pesticide-tolerant insect pests recognise and inactivate chemical and biological toxins is poorly understood. While vertebrates with a closed circulatory system use coagulation reactions mainly for wound-healing, invertebrates employ cell-free aggregation reactions for the sequestration and inactivation of potentially damagin ....Cell-free immune reactions and suppression. Insects pests and insect vectors of diseases are managed by toxic substances, but insects have a cunning ability to persist. How pesticide-tolerant insect pests recognise and inactivate chemical and biological toxins is poorly understood. While vertebrates with a closed circulatory system use coagulation reactions mainly for wound-healing, invertebrates employ cell-free aggregation reactions for the sequestration and inactivation of potentially damaging objects and substances. We use insect plasma to dissect recognition and inactivation of damaging objects and substances with the aim to understand tolerance and its inhibition to design novel strategies in delaying tolerance to pesticides in insect pests.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
Cellular and molecular interactions of rhabdoviruses with their plant hosts and insect vectors. Viruses cause significant economic losses in agriculture, but little information is available on how plant-adapted rhabdoviruses multiply in both their plant hosts and insect vectors. This project on the localisation, transport and host defence properties of essential viral proteins will identify novel targets for improved disease control.
Generation of bananas with resistance to Fusarium wilt. Bananas are an important fruit crop in Australia, but the industry is continually threatened by numerous diseases such as Fusarium wilt. This project aims to generate transgenic banana plants with resistance to Fusarium wilt, a disease for which no effective control strategies currently exist.
