Abstract
Red clover (Trifolium pretense L.) varieties in the third season of growth, that had been exposed to a heavy infestation of larvae of the clover leaf weevil [Hypera punctata (Fabricius)], differed significantly in percentage defoliation, feeding injury score, plant height, and forage production. Based on these four characters, 'Mammoth,' 'Lakeland,' 'Dollard,' and 'LaSalle' were highly resistant to larval feeding; 'Kenland,' 'Common,' and 'Pennscott' were highly susceptible. Long term second-season yield tests including six of these varieties indicated no con• sistent superiority of any of the varieties in the absence of weevil feeding.
