Using variation in wing shape to distinguish between wild and mass-reared individuals of Queensland fruit fly, Bactrocera tryoni.

The article presents a study investigating the use of the geometric morphometrics in differentiating wild from mass-reared Bactrocera tryoni, a species Queensland fruit fly common to all horticultural crops in eastern Australia. Sterile flies coming out in supervising traps after release are described by the presence of fluorescent dust in the ptilinum. The result indicates that wing size variation is not sufficient to reliably differentiate wild and sterile flies.
