About the Opportunity:

Charles Darwin University (CDU) and CSIRO are partnering to offer an exciting PhD opportunity focused on population genetics and Bt resistance in the emerging cotton pest Spodoptera litura. Cotton production in Northern Australia is expanding rapidly, but the region differs markedly from the southern cotton production areas, particularly in climate, cropping systems, and pest management practices. These differences likely shape the biology, movement, and resistance profile of key insect pests, yet there is very limited empirical data to validate this. Understanding the risks posed by northern production systems is essential to ensuring that the Resistance Management Plan (RMP) continues to minimise the evolution of Bt resistance in cotton pest species across Australia. A major knowledge gap relates to Spodoptera spp., particularly S. litura, an emerging pest in northern landscapes. Little is known about its life history in Australian cotton systems, patterns of dispersal and gene flow, current and potential pesticide resistance or role in broader landscape-level dynamics. This PhD project will provide the first comprehensive assessment of S. litura population structure, movement, and resistance development across Northern Australian cotton landscapes. The research will form the foundation for future modelling and management strategies, helping industry anticipate and mitigate emerging pest risks. This is an excellent opportunity to work at the interface of molecular ecology, agricultural biosecurity, and sustainable pest management, with strong support from both CDU, CSIRO, CRDC and industry.
