Abstract: Twenty-one sweet potato varieties are assessed at two locations for resistance to the West Indian sweet potato weevil, Euscepes postfasciatus (Fairmaire). All varieties are susceptible, although B-63-726, the most highly acceptable variety, showed some resistant qualities. Insect populations were generally very high at the Central Agronomic Research Station, one of the trial sites, and extensive tuber damage resulted. C-104, 0/100 and T-62 were the ones most seriously affected. A26/100, A26/86, T-57 and 0/100 yielded poorly at both sites. Excellent yields were obtained from the Fairview trial site. Tubers of most varieties are relatively free of infestation for the greater part of their growing period. Proper timing of harvest of tubers, enables relatively insect-free tubers to be obtained.
