Abstract
Two experiments were carried out to investigate the response of Phthorimaea operculella (Zeller) pupae to certain doses of gamma rays and ultra violet light. In the first experiment, 2-days old pupae were irradiated with doses ranging from 1 to 20 krad of gamma rays from sucrose. In the second experiment, pupae of the same age were exposed to 5.4, 10.8, 21.6 and 32.4 Jol/cm2/second of ultra violet light (UVL). Ganna rays as well as (UVL) had adverse effect on some biological aspects of the insect. In general, these effects were greater as the treatment increased in the parental generation the first generations. Sterility reached 91.9% and 86.6% after pupal treatments with 15 K rad and 32.4 Jol/cm2/sec., respectively. Therefore, the use of gamma rays and UVL is recommended for any sterile-male technique for the control of the potato tuber moth, Phthorimaes opercullela (Zeller).
