 Ginger Korosi

Prior to starting her PhD, Ginger worked for the Victorian Department of Environment and Primary Industries Rutherglen Centre. During her 8 years employed as a Research Scientist, Ginger's work included laboratory, glasshouse and field evaluation of grape phylloxera (Dactulosphaira vitifoliae) genotype and grapevine rootstock interactions. Ginger also performed grapevine phylloxera risk assessments looking at phylloxera survival under heat treatment conditions, in composting winery waste and in must.

Ginger was awarded an Australian Postgraduate Award in 2013 to study a PhD at Charles Sturt University. She was also awarded a Grape and Wine Research and Development Corporation top-up scholarship.

Specialization:     Biological control of grapevine phylloxera.

Focus area:    Entomopathogenic fungi as potential biocontrol agents of grape phylloxera.

Biological control agents are natural enemies of agricultural pests and include invertebrates and entomopathogenic fungi. Naturally occurring entomopathogenic fungi have the ability to parasitise insects and arachnids. They are generalist pathogens causing mortality to a broad range of insect hosts, making them suitable for extensive investigations as biological control agents of insect pests.

Grapevine phylloxera (Daktulosphaira vitifoliae) is a quarantine grapevine pest in Australia. The radicole form of phylloxera attacks the root system of European grapevines (Vitis vinifera) causing mortality of the vine. Thus far phylloxera has been managed by using American rootstocks where phylloxera does not develop in as high numbers or by adhering to strict quarantine regulation to keep the insect out of the non-infested regions.

The aim of the PhD project is to isolate entomopathogenic fungi that are effective against grapevine phylloxera.
