The sterile insect technique has been in use for more than 50 years. Release techniques vary considerably from country to country. The release of sterile Queensland fruit fly in Australia continues to progress since its initial trials in the 1960's. Three ground release methods (adult tub, adult chilled and pupal bucket) for sterile Queensland fruit fly were evaluated in the field. The recapture rate from the adult tub release method is significantly better than the other two methods. Adult chilled release had the lowest recapture rate but was not significantly different from the pupal bucket release. All methods could have been improved. 98.8% of recaptured flies were trapped within 600m of the release points. The dispersal distance was compared with other species. (C) 2011 Esevier Ltd.
