Abstract
Caribbean fruit fly pupae were subjected late in their development to gamma radiation (Cs-137) doses of 0, 15, 20, 25, 30, 50 and 70 Gy. Twelve hours after the eclosion, adults were transferred into small cages and held under 14 hour photophase at 26@*C and 70% RH. Ovarian dissections were performed at 1, 5, 10, 15, 20, 25 and 30 days after adult eclosion. Irradiated females showed abnormally-developed ovaries and doses of 25 Gy and higher caused severe atrophy. Regeneration was not observed. All irradiated females possessed hypertrophied accessory glands, probably due to accumulation of secretions normally used to lubricate the oviduct.
