Newly emerged adult males of Dacus cucumis were irradiated with 1, 3 and 5 krad of gamma radiation at dose rates of 9.51. 4.38, 2.98 and 0.87 krad/min. There was no significant effect of dose rate on sterility or longevity. When males were irradiated with 7 or 9 krad at rates of either 9.51 or 0.87 krad/min there was no significant effect of dose rate on competitiveness of the males. A dose of 9 krad gave significantly less competitive males than did a dose of 7 krad.
