Tests were conducted to determine the amount of Co/sup 60/ gamma radiation or x radiation necessary to apply to cysticanercoids of Hymenolepis diminuta, the rat tapeworm, in order to render them noninfective. Cysticercoide were obtained by feeding flour beetles (Tribolium confusum) with infective eggs from the tapeworm; the cysts recovered from the beetles were irradiated and counted numbers were fed to white rats to determine their ability to produce tapeworms. A dose of 12,000 rep Co/sup 60/ or 12,000 r x-ray prevented most cysticercoids from developing to tapeworms, and in some cases the few tapeworms that developed were stunted or sexually sterile. Doses of l5,000 rep Co/sup 60/ or 15,000 r x ray generally prevented cysticercoids from developing into adult tapeworms. (auth)
