Description: 

Using population genomics to resolve the species identity of New Zealand brown-headed leafroller moths, high priority biosecurity threats to Australian avocados.
Project Description: Diagnostics are critical for Biosecurity, and the Australian Avocado industry is threatened by the potential invasion of Brown-headed leafroller moths (Ctenopseustis obliquana and C. herana) from New Zealand. These moths have very high entry potential given the proximity of New Zealand. They are morphologically nearly identical but differ in the male attraction to different sex pheromones. DNA barcoding using the mitochondrial COI gene has been inadequate for distinguishing the two species. This research aims to resolve their species identities using population genomic approaches and develop species-specific diagnostic assays, to ultimately improve the biosecurity diagnostic capacity and capability as part of the Australian avocado industry’s preparedness.

Additional Information: 

The student/s will have the opportunity to improve their knowledge and skills in entomology, molecular biology and bioinformatics, and develop industry connections. This project is a funded collaboration with Nga Tran and Andrew Geering at QAAFI. There is also the opportunity for funded travel and fieldwork in New Zealand.
