Abstract

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.
