Beach strawberry,Fragaria chiloensis(L.) Duchesne, clone CL-5, is resistant to feeding by adult black vine weevil (BVW),Otiorhynchus sulcatus(F.). Using a membrane filter feeding bioassay, no evidence for a chemical basis for this resistance could be obtained. Leaf toughness of a susceptibleFragaria×ananassa(Duchesne) cultivar and clone CL-5 did not differ. Removal of tomentum from the underside of fresh or freeze-dried CL-5 leaf disks rendered them as susceptible to BVW feeding as disks from a nonresistant cultivar. This, and other evidence, demonstrates that antixenosis exhibited by leaves of beach strawberry clone CL-5 to BVW is due, at least in part, to the dense covering of simple hairs on their abaxial surface.
