Preparatory processes in rapid interceptive action. This project investigates the nature of the processes involved in preparing to act in response to a moving object: actions that elite sportspeople perform with amazing precision: timing to within a few thousandths of a second is routine when hitting a ball in tennis and cricket. The average person can be capable of something similar and it means being ready to make the right movement at the right time.

This project investigates the nature of the processes involved in preparing to act in response to a moving object: actions that elite sportspeople perform with amazing precision: timing to within a few thousandths of a second is routine when hitting a ball in tennis and cricket. The average person can be capable of something similar and it means being ready to make the right movement at the right time. Understanding the preparatory processes involved will be a significant scientific advance and knowledge of their workings and limits can contribute to the development of strategies for improving safety in dynamic environments such as city roads. This project will put an Australian laboratory at the cutting edge in this area of research.Read moreRead less
Insect host/vector genetic responses to rhabdovirus infection. Rhabdoviruses cause important diseases in humans, animals and plants. These viruses are transmitted by insect vectors in which they persist and propagate, an intimate and specific association. Insect-rhabdovirus interactions will be studied at the molecular level using a planthopper-maize rhabdovirus model. Insect genes specifically induced by rhabdovirus infection as well as the viral genes themselves will be identified and characte ....Insect host/vector genetic responses to rhabdovirus infection. Rhabdoviruses cause important diseases in humans, animals and plants. These viruses are transmitted by insect vectors in which they persist and propagate, an intimate and specific association. Insect-rhabdovirus interactions will be studied at the molecular level using a planthopper-maize rhabdovirus model. Insect genes specifically induced by rhabdovirus infection as well as the viral genes themselves will be identified and characterized using genomics and bioinformatics tools. We will extend the same approaches to a comparative analysis of these planthopper genes with other insect-rhabdovirus systems under investigation in our institutes. Identification of viral genes expressed in insects, the insect genes that respond to virus infection, and interpretation of the roles of these genes in insects, may indicate new opportunities to control serious plant and animal diseases through control of virus transmission.Read moreRead less

Understanding an exotic disease: Initiation of sex and infection by the sugarcane smut Ustilago scitaminea. Australian sugar exports generate almost $2 billion in annual sales, making the sugar industry a critical facet of the Australian economy. In 2006, Australia's primary sugar producing region came under threat when an outbreak of sugarcane smut caused by the fungus Ustilago scitaminea first appeared in Queensland. Management of this potentially devastating disease has focused on breeding pr ....Understanding an exotic disease: Initiation of sex and infection by the sugarcane smut Ustilago scitaminea. Australian sugar exports generate almost $2 billion in annual sales, making the sugar industry a critical facet of the Australian economy. In 2006, Australia's primary sugar producing region came under threat when an outbreak of sugarcane smut caused by the fungus Ustilago scitaminea first appeared in Queensland. Management of this potentially devastating disease has focused on breeding programmes aimed at developing resistant sugarcane cultivars, a complex process hampered by a lack of information about the mechanisms of smut resistance. Our research will provide key insight into the mechanisms by which U. scitaminea infects sugarcane, directing future breeding efforts and protecting this valuable industry against further outbreaks.Read moreRead less

Australians are increasingly exposed to insect-transmitted diseases such as dengue fever. Novel biocontrol methods using the bacterium Wolbachia aim to control insect populations to reduce disease transmission. Our research will be the first to investigate genomic variation and the process of adaptation to new insect hosts in Wolbachia. The novel data and understanding of evolutionary processes we generate will be critical for screening bacterial biocontrol candidates and designing biocontrol release strategies. It will also strengthen the position of Australian research as a world-leader in the fusion of post-genomics and applied microbiology. Read moreRead less
Host provisioning by Wolbachia: re-examining the invasion potential of a common invertebrate endosymbiont. Wolbachia are often described as reproductive parasites that manipulate their host for their own gain. This study will determine for the first time how Wolbachia can help its insect host during periods of nutritional stress. As Wolbachia are able to infect host populations it will be used in the near future to control insects that transmit disease or are commercial pests. Understanding how ....Host provisioning by Wolbachia: re-examining the invasion potential of a common invertebrate endosymbiont. Wolbachia are often described as reproductive parasites that manipulate their host for their own gain. This study will determine for the first time how Wolbachia can help its insect host during periods of nutritional stress. As Wolbachia are able to infect host populations it will be used in the near future to control insects that transmit disease or are commercial pests. Understanding how Wolbachia interacts with its host, as a parasite or beneficial, will improve its application in the field. Knowing how benefits are provided to the host will improve human health in the future. As Wolbachia are needed for filarial nematode development, disrupting the beneficial mechanisms identified in this study will improve filariasis control programsRead 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.

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
Insect age: an ecological genomics approach to understanding host-parasite interactions. The importance of insect age (or the age structure of a population of insects) in understanding relationships between insects and their abiotic and biotic environment has been stressed in many theoretical studies but seldom directly tested. This is because few tools exist that can accurately measure the age of a wild-caught insect with any accuracy. In this proposal we plan to use a genomics approach to deve ....Insect age: an ecological genomics approach to understanding host-parasite interactions. The importance of insect age (or the age structure of a population of insects) in understanding relationships between insects and their abiotic and biotic environment has been stressed in many theoretical studies but seldom directly tested. This is because few tools exist that can accurately measure the age of a wild-caught insect with any accuracy. In this proposal we plan to use a genomics approach to develop tools that can be used to efficiently determine the age of an insect and then apply these tools to better understand the relationship between insect age and the ability of an insect to transmit pathogens to humans, livestock or plants. These tools will also have future applicability in developing new approaches to control insect transmitted disease as well as provide methodology to determine the effectiveness of current control programs that seek to kill pest insect populations of agricultural or public health significance.Read moreRead less

The bacterial symbiont Wolbachia is found in many major pests of agricultural and medical importance. Our results will give insights into how Wolbachia spreads into host populations and improve its use as a tool to impair insect transmission of disease, e.g. as an agent to carry genes into an insect population that limit disease transmission. Our results will also make fundamental contributions to understanding host-parasite evolution, host-parasite communication, and insect developmental processes, and will be of interest to a large international community of researchers in this field.
