Irradiation studies were conducted with three sweet potato, Ipomoea batatas (L.) Lam., pests to determine an effective dose for quarantine control. Dose-response tests indicated that the most radiotolerant stage occurring in roots was the pupa of sweetpotato vine borer, Omphisa anastomosalis (Guenee), and the adult of West Indian sweetpotato weevil, Euscepes postfasciatus (Fairmaire), and sweetpotato weevil, Cylas formicarius elegantulus (Summers). In large-scale confirmatory tests, irradiation of 60,000 C. formicarius elegantulus adults, 62,323 E. postfasciatus adults, and 30,282 O. anastomosalis pupae at a dose of 150 Gy resulted in no production of F sub(1) adults, demonstrating that this dose is sufficient to provide quarantine security.
