What was it all about?
This investment has successfully demonstrated a method to develop a ‘temperature-sensitive lethal, male-selecting’ strain of Queensland fruit fly (Qfly). To put simply, this research will allow for male-only, sterile fruit flies to be bred in large numbers. It is one of the key projects in the broader strategic co-investment SITplus initiative that’s tackling the issue of Qfly. The male flies are to ultimately be released in growing regions of south-eastern Australian that are affected by Qfly. They will come to outnumber the wild male population in these areas and by mating with wild females – and limiting the opportunity for wild males to do so – they are intended to lead to the collapse of wild Qfly populations.
Levies from several horticulture industries are involved in the project which, as a SITplus initiative, is part of the Hort Frontiers Fruit Fly Fund.
