Research carried out in 1964–65 at the “Democritus“ Nuclear Research Center has ascertained that when pupae of the olive fruit fly, Dacus oleae (Gmelin), are exposed to 8, 10, and 12 krad of gamma rays, permanent dominant lethality is caused to sperm to a degree which can be considered satisfactory for practical purposes. It has shown also that 6 krad was a satisfactory male-sterilizing dose. At these doses not more than 2.6% of the progeny of irradiated males mated with normal females reached the first larval instara, and not more than 0.3%reached the pupal stage, as compared with 82.3% and 41.4% in the control, respectively. The same doses caused permanent sterility to the irradiated females. They did not substantially alIect the time or the percent of adult emergence, or the Iongevity of irradiated males.
