Abstract A laboratory method based on adult feeding punctures was developed to rapidly evaluate cultivars and breeding lines of sweet potatoes Ipomoea batatas (L.) Lam for resistance to the sweetpotato weevil, Cylas formicarius elegantulus (Summers). Promising resistant lines can be identified, and the amount of field testing required to develop resistant lines is reduced. Preliminary data indicate that varying levels of resistance exist in sweetpotato.
