Role

To initiate and conduct research, technology development and knowledge exchange projects to ultimately enable the integrated pest management (IPM) of current and emerging pests of sugarcane by small- and large-scale growers.

Expertise

Biological Control, Entomology, Nematology, Organic Control, Technology Transfer, Project Management

Research Focus

  • The development and delivery of area wide IPM tools for pests, particularly Eldana
  • Establishing proof-of-concept of the potential of the novel SASRI F1 sterile insect technology (SIT) to serve as an effective component of Eldana IPM
  • Collaboration in research, technology development and knowledge exchange projects that require entomological expertise
  • In conjunction with the SASRI Extension, Biosecurity and Knowledge Management functions, communicate on pest management issues with industry role-players and stakeholders at all levels.
  • Contribute entomological expertise in support of SASRI operations and services, including:
  • Production of arthropod materials for: (a) sugarcane screening trials for Eldana resistance; (b) approved research projects; and (c) the weed biocontrol agent production service; and
  • Commercial studies commissioned and funded by external third parties on pest control compounds or agents deemed by SASRI to have potential value to sugarcane growers.
