The Sterile Insect Technique (SIT) could be an effective tool in the fight against Queensland fruit fly, by releasing large numbers of sterile male flies to mate with females in areas infested with the pest. However, to compete with wild males the sterile male flies must also be high quality ‘fitter’ males, attractive to females.
This project investigated genetic mechanisms regulating mating and fitness traits in Queensland fruit fly, and how these are passed on through generations.
The project’s final report, published in 2016, adds a large amount of genetic data on fruit flies to the knowledge base that will assist in producing good quality sterile male flies. In so doing, the effectiveness of SIT will be enhanced.
In addition, the project boosted Australia’s expertise in applying genetic techniques to pest management in horticulture and other agricultural sectors.
This project was a strategic levy investment in Hort Innovation's across-industry program
