Breeding a male-only strain of Queensland fruit fly (FF18002)
What’s it all about?
This investment is developing a male-selecting strain of Queensland fruit fly for use in the Port August SITplus facility. This research will build on the efforts made by SITplus: Developing and optimising production of a male-only, temperature-sensitive-lethal strain of Qfly, B.tryoni (MT13059) and Sex selection genes from fruit fly species for use in SITplus (FF17000).
To put it 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.
