Technical Abstract: Two insect susceptible check cultivars (‘Beauregard’ and ‘SC1149 19’), three insect resistant check cultivars (‘Charleston Scarlet’, ‘Regal’, and ‘Ruddy’), two commercial varieties (‘Covington’ and ‘Diane’), and 34 advanced genotypes from the USVL sweetpotato breeding program were evaluated for insect resistance in replicated field trials at Charleston, SC, in 2012. Twenty genotypes had significantly less overall insect injury (i.e., higher percentage of undamaged roots), and 18 genotypes had significantly lower WDS indices than did the two susceptible checks. All but four genotypes had significantly less injury by flea beetles than did ‘SC1149-19’. Nineteen genotypes had significantly less grub damage, and 35 had significantly less weevil damage than did ‘SC1149-19’.
