The damage caused by the apple weevil or apple curculio (Otiorrhynchus cribricollis Gylh) takes several forms, the most apparent being marginal leaf damage. However, the bark chewing habit probably has a more direct effect on yield for it may cause ring-barking of the main leaders and growing shoots with their consequent die-back and the prevention of full development of immature fruit. The larvae or grub forms may also cause some root injury.
