Abstract
Queensland fruit flies, Bactrocera tryoni (Froggatt) (Diptera: Tephritidae) ('Q-flies') were released as sexually immature adults from a point within an orchard. Marked male Q-flies were recaptured in the trap furthest from the release point (1087 m) by 2 weeks after release, although 98.25 1.04% of recaptured males were trapped <500 m from the release point. Comparison of gamma-irradiated (sterile), laboratory-adapted and wild male Q-flies indicated that dispersal distance was not significantly affected by fly type. There was no significant correlation between temperature and mean dispersal distance, but total recaptures were significantly negatively correlated with increasing daily maximum, minimum and average temperature.
