Feeding preference of the adult clover head weevil ( Hypera meles F.) was determined on 90 inbred lines of crimson clover ( Trifolium incarnatum L.). Significant differences were observed among inbred lines in whole plant (seedling) feeding tests in the greenhouse and mature leaf disc tests, but not in seedling stem feeding tests in a growth chamber. Whole plant feeding tests yielded results similar to leaf disc tests but required much less labor. Correlations between leaf disc feeding and leaf pubescence were to variable and too low to be of much value in selection for weevil resistance.
