Dosage-mortality studies on the combined effects of 5000 R gamma irradiation and malathion applied topical. ly to adult house flies. Musca domestica L., indicated that (1) newly pupated males, irradiated 4 days before emer- gence, were significantly more tolerant to malathion than when irradiated 2 or 3 days before emergence; (2) fe- male pupae irradiated 2 days before emergence are more tolerant to malathion than when irradiated at any other time. Gamma irradiation increased malathion tolerance more than X-irradiation in both males and females when pupae were irradiated with equal dosages. It is suggested that the increased resistance in Hies from irradiated pupae may be attributed to increased detoxifying enzyme levels.
