Abstract

The sterilising effect of 90Sr β-radiation was tested against males and females of Glossina palpalis palpalis (R.-D.) 1–6 days old. The flies were exposed to doses ranging from 2 to 40 krad at a dose-rate of l·09 × 103 rad/min. The optimal sterilising dose for the males was about 7·5 krad. Females that mated with males that had been exposed to this dose failed to produce larvae although the sperm of the treated males was motile. There was no relation between dose and length of life at doses from 2 to 10 krad but at higher doses survival was greatly reduced. Females survived irradiation better than males.
