Origins of Parasitism in the Psocodea (Insecta). The Psocodea has 2 groups: the lice and the psocopterans (the psocids and their kin). The lice are parasites whereas the psocopterans are free-living. The Psocodea are a unique model-system that will allow us to discover the processes that preadapt arthropods for parasitism and the processes that facilitate "explosive" radiations of arthropods once they become parasites. We will infer evolutionary trees for these insects from 3 genes. Then we ....Origins of Parasitism in the Psocodea (Insecta).

The Psocodea are a unique model-system that will allow us to discover the processes that preadapt arthropods for parasitism and the processes that facilitate "explosive" radiations of arthropods once they become parasites. We will infer evolutionary trees for these insects from 3 genes. Then we will use these trees to track the evolution of feeding, attachment, senses and reproduction through evolutionary time. Our work should provide unprecedented insight into the evolution of parasitism in the arthropods.Read moreRead less

Summary
Investigating the interaction of microRNAs-Wolbachia-Dengue virus in the mosquito vector, Aedes aegypti. This project focuses on using molecular techniques to discover fundamental roles of small RNA molecules (microRNAs) of a key mosquito vector in bacterial symbiosis and Dengue virus infection. It will lead to development of effective approaches in limiting spread of vector and transmission of life threatening viral diseases.
Novel control strategies for mosquitoes threatening Australia. Increased global transport and human mobility have led to the spread and establishment of potential disease vectors and pathogens of public health importance in many parts of the world from which these were absent or had been eradicated. Aversion of this risk can be more effective when applying area-wide rather than focal (e.g. insecticide) control efforts. We will further the development of genetic and biological control tactics.

Increased global transport and human mobility have led to the spread and establishment of potential disease vectors and pathogens of public health importance in many parts of the world from which these were absent or had been eradicated. Aversion of this risk can be more effective when applying area-wide rather than focal (e.g. insecticide) control efforts. We will further the development of genetic and biological control tactics. We aim to reduce the risks posed by two important dengue-vectoring mosquitoes: the yellow fever and the Asian tiger mosquito. This will lead to environmentally friendly and sustainable mosquito control and protect the Australian population and its regional neighbours against the threats of mosquito-borne disease.Read moreRead less
Cross-kingdom communications via small non-coding RNAs. This project aims to determine the role of small non-coding RNAs in mosquito-Wolbachia interactions, including Wolbachia microRNAs, concentrating on exchanged microRNAs between the two organisms and explore microRNAs effect on Wolbachia maintenance and its anti-viral property. Small non-coding RNAs play significant roles in various biological processes, including host-microorganism interactions. Recent evidence suggests that small RNAs can ....Cross-kingdom communications via small non-coding RNAs. This project aims to determine the role of small non-coding RNAs in mosquito-Wolbachia interactions, including Wolbachia microRNAs, concentrating on exchanged microRNAs between the two organisms and explore microRNAs effect on Wolbachia maintenance and its anti-viral property. Small non-coding RNAs play significant roles in various biological processes, including host-microorganism interactions. Recent evidence suggests that small RNAs can be exchanged between microorganisms and their hosts and regulate gene expression in the other organism. The endosymbiotic bacterium, Wolbachia, has attracted worldwide attention due to inhibiting replication of various vector-borne pathogens in mosquito vectors.Read moreRead less
Regulatory cellular microRNAs and their role in insect anti-viral responses. This project will use cutting edge approaches to reveal fundamental roles of small ribonucleic acid molecules (microRNAs) in insect anti-viral responses and immunity. By manipulating anti-viral immune responses, the project will assist in the design of novel approaches to pest control and abolish/limit transmission of vector-borne viruses such as Dengue virus.
