When pupae of Plodia interpunctella (Hübner) were irradiated with various doses of --irradiation at different ages, the degree of sterility and the reproductive ability of the emerging adults varied with dose and with age at the time of irradiation. When 4- to 5-day-old pupae were treated with 35 or 50 krad, resultant adult females were sterile, and the reproductive ability of the males was reduced greatly, Also, progeny from the partially sterile males was sterile or nearly so, Treatment of pupae minimizes the problem of collecting and irradiating large numbers of adults, eliminates the need to handle, sex, and segregate the adults, and facilitates the distribution and release of treated insects (as pupae within the cardboard rolls).
