Dr Amanda Choo is a Grant-funded Researcher in the School of Biological Sciences at the University of Adelaide and works closely with the Entomology Unit at the South Australian Research and Development Institute (SARDI). Her research focuses on developing genetic strains for the use of agricultural and biosecurity pest control. She was the first in her research field to establish the CRISPR/Cas genome editing technology in tephritid fruit flies, with her work being amongst the top cited articles in the Journal of Applied Entomology in 2018-2019 (Choo et al., 2018). Dr Choo has been awarded the Dean’s Commendation for Doctoral Thesis Excellence (2015), University of Adelaide School of Biological Sciences Postgraduate all round Achievement Award (2015), Insect Genetic Technologies Research Coordination Network (IGTRCN) Peer-to-Peer Training Fellowship (2016), SARDI Publication of the Year Award (2020) and Australian Federation of University Women Postdoctoral Grant (2021). Dr Choo is a member of the national SITPlus Technical Advisory Committee and have strong collaborations with various tephritid fruit fly research groups, both nationally and internationally.
Sterile Insect Technique (SIT) involves mass rearing and release of sterile male insects to control and suppress outbreak populations of pest species. The released sterile males will mate with wild females, resulting in the females producing non-viable eggs, ultimately acting as a “birth control” strategy. This will lead to the reduction and/or eradication of pest species in the targeted area.
I'm working in collaboration with the South Australian Research and Development Institute (SARDI) as part of the SITplus consortium to develop SIT strains to control one of the major horticultural pests in Australia, Bactrocera tryoni (Queensland fruit fly). My research focus is on using gene editing technologies such as CRISPR/Cas9 to produce novel and improved strains that can increase the efficacy and efficiency of SIT.
Current research projects:
- Development of Bactrocera tryoni temperature-sensitive lethal strains using CRISPR/Cas mutagenesis (Choo et al., 2020 ; Nguyen et al., 2021)
- Production of different pupal colour strains for Bactrocera tryoni (Ward et al., 2021)
- Translocation of autosomal gene regions to the Y chromosome in Bactrocera tryoni
Current HDR student projects:
- Generation and characterisation of visible markers in Bactrocera tryoni for sterile release (Nguyen et al., 2021)
- Characterisation of Bactrocera tryoni pupal colour mutant strains
Potential Honours projects:
- CRISPR mutagenesis of the yellow2 gene for Queensland fruit fly control
