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

Summary
High throughput orthogonal mass spectrometer for biotechnology research in WA. The new 'orthogonal' mass spectrometer will be housed at the WA State Agricultural Biotechnology Centre at Murdoch University (SABC). The SABC is a multi-user university centre that provides equal access for researchers from all universities, state government and industry to major facilities. The equipment will provide a competitive advantage to researchers undertaking fundamental and applied projects that underpin ....High throughput orthogonal mass spectrometer for biotechnology research in WA. The new 'orthogonal' mass spectrometer will be housed at the WA State Agricultural Biotechnology Centre at Murdoch University (SABC). The SABC is a multi-user university centre that provides equal access for researchers from all universities, state government and industry to major facilities. The equipment will provide a competitive advantage to researchers undertaking fundamental and applied projects that underpin new developments in plant and animal agriculture. Outcomes include: development of new molecular markers to speed crop improvement and quality, animal genetic improvement and health, and support for new biotechnology companies. This will benefit the community through more productive, competitive and sustainable agriculture.Read moreRead less
Peptidic spider toxins: a novel paradigm for control of insect pests. Many insects are serious pests of Australian crops, livestock, and pets. 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 around the home and garden, and on pets. Viruses disseminated by insects are also responsible for diseases such as dengue, Japanese encephalitis, and Ross River fever. Unfortunately, ....Peptidic spider toxins: a novel paradigm for control of insect pests. Many insects are serious pests of Australian crops, livestock, and pets. 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 around the home and garden, and on pets. Viruses disseminated by insects are also responsible for diseases such as dengue, Japanese encephalitis, and Ross River fever. Unfortunately, many of these insect pests have developed resistance to chemical insecticides. The aim of this research program is to develop a new generation of environmentally-friendly natural products and insect-resistant crops that can be used to control insect pests on farms and around the home and garden.Read moreRead less
Orally active spider toxins: a novel paradigm for control of insect pests. Many insects and other arthropods are serious pests of Australian crops, livestock, and pets.

Safeguarding Australia against invasive arthropod pests. An increasingly serious public health issue for Australia is the emergence of infectious diseases disseminated by arthropods such as ticks and mosquitoes. Arthropod-borne viruses are already the major human pathogens in Australia, and they disproportionately affect Aboriginal communities. The aim of this research is to develop environmentally-sustainable methods for controlling arthropods that destroy crops or disseminate human and animal ....Safeguarding Australia against invasive arthropod pests. An increasingly serious public health issue for Australia is the emergence of infectious diseases disseminated by arthropods such as ticks and mosquitoes. Arthropod-borne viruses are already the major human pathogens in Australia, and they disproportionately affect Aboriginal communities. The aim of this research is to develop environmentally-sustainable methods for controlling arthropods that destroy crops or disseminate human and animal disease. These insecticides will not only provide benefits within Australian territories, but will be useful to our defence forces when operating in overseas locations where arthropod pests are a problem (e.g., malarial regions of Iraq).Read moreRead less
