dc.description.abstract Rough sweetpotato weevil, Blosyrus asellus (Olivier), is a new quar- antine pest of Hawaii sweetpotatoes. Currently, sweetpotatoes can be exported from Hawaii to the U.S. mainland using a postharvest irradiation treatment of 150 Gy to control three other regulated insect pests. Studies were conducted to deter- mine whether this current radiation dose will also control any rough sweetpotato weevils in export shipments. Adult weevils were treated at various levels between 25 to 125 Gy and egg laying and egg hatch were measured. Rough sweetpotato weevil was found to be highly susceptible to irradiation, with no egg hatch at any radiation dose, even 25 Gy, the lowest dose tested. Results suggest that the 150 Gy irradiation treatment should be sufficient for control of rough sweetpotato weevil in Hawaii sweetpotatoes.
