Two species of parasitic wasps, identified in southern NSW during on-going research at Charles Sturt University (CSU), could unlock new ways to fight fruit fly in Australia. PhD student Mrs Jennifer Spinner has been collecting fruit ‘stung’ by fruit fly in home gardens during the fruit fly season (October to May) in Albury, Cootamundra, Ganmain, Gundagai, Lake Cargelligo, Lockhart and Wagga Wagga. The fruit has been held in a laboratory at CSU at Wagga Wagga in a controlled temperature environment until adult fruit fly or parasitic wasps emerge. “I am examining whether the wasps are present in inland NSW and whether large releases of the wasps could be used for the biological control of fruit fly,” said Mrs Spinner. The female wasp lays her eggs inside the fruit fly larvae, which hatch and feed on the fruit fly larvae, ultimately killing the pest. In 2009, the PhD student will travel to Guatemala, Hawaii and Mexico where releases of parasitoids have improved the management of fruit fly.
