Technical Abstract: Three insect susceptible cultivars (‘Beauregard’, ‘Hernandez’, and 'SC 1149-19'), two insect-resistant cultivars ('Charleston Scarlet' and ‘Ruddy’), and 43 advanced sweetpotato genotypes were evaluated for insect resistance in replicated field trials at Charleston, SC. Thirty-three genotypes had significantly less overall injury from insects (ie., higher percentage of undamaged roots) and 30 entries had a significantly lower WDS index than did the two susceptible checks (‘Beauregard’ and ‘SC1149-19’). All genotypes had significantly less injury by flea beetles than did ‘SC1149-19’.
