Abstract:In laboratory tests conducted at Honolulu, Hawaii,from 1964 to 1968, oriental fruit flies,Dacus dorsalis Hendel, and Mediterranean fruit flies, Ceratitis capitata (Wiedemann), sexually sterilized with tepa, lived longer than untreated flies of both sexes. Longevity increased with higher dosages of tepa until the chemosterilant acted as a toxicant. Females of these species sterilized bygamma rays lived longer than their untreated Counter- parts, but male longevity was not increased. The melon fly, D. cucurbitae Coquillett, reacted conversely, in that when it was sterilized by either method, longevity was decreased. Radiation-sterilized or chemosterilized adults of all 3 species withstood food and water deprivation bet ter to varying degrees than their untreated counterparts, when tested at ages associated with 50% natural mortality in populations. They also required more DDT or mal athion to achieve comparable mortalities at the LD50 and LD95 levels than nonsterilized flies.
