The infested fruits do not usually fallto the ground, as do apples aiFected by the codling worm, butremain attached to the tree, and the insect, from its habitof living within the fruit through all its stages, is a difficultone to destroy. Picking the affected sj)ecimens from thetree, and vigorously jarring the tree during the time whenthe beetle is about, will bring it to the ground, where it canbe destroyed in the same manner as recommended for theplum curculio.
