Research | Current

Identification, synthesis and biological testing of semiochemicals in horticulture

Supervisors:

Assoc. Prof. David Barker (University of Auckland)

Prof. Max Suckling (University of Auckland/Plant & Food Research)

Dr. Bruno Fedrizzi (University of Auckland)

My research focuses on the chemical communication of insects and plants. The chemical signals (semiochemicals) used by these organisms play both beneficial and detrimental roles in their lives. Identifying the semiochemicals used and understanding how they influence behaviour can lead to the development of species specific tools to modify insect behaviour and protect horticultural crops in an environmentally friendly manner.

Areas of expertise

Semiochemical identification (GC-MS)

Semiochemical synthesis

Electrophysiological testing (GC-EAD)

Chemical ecology
