Abstract: EPA cancellation of the use of the fumigant EDB gave rise to research of alternative methods for disinfestation of agricultural commodities susceptible to infestation by various species of fruit flies. One potential alternative is X-ray radiation. Three series of tests were conducted with xMarsh' white grapefruit artificially infested with larvae of the Caribbean fruit fly, Anastrepha suspensa (Loew), and exposed to 5, 10, 20, 30 and 35 krads of X-ray radiation. Percent reduction of insects ranged from 82.8-100, with Probit 9 mortality estimated above 35 krad. No adult flies emerged from larvae exposed to any level of X-ray tested. The rate of deterioration increased in fruit exposed to 30 and 35 krad.
