Excerpt from Orchard Insects of the Pacific Northwest and Their Control The larva or worm is the only injurious stage of the codling moth, and the only injury of consequence is to the fruit. The young worms, upon hatching from the eggs, crawl to the nearest fruit and burrow into it, producing the familiar wormy apple or pear. Many worms enter through the calyx end, Where the calyx affords them protection and they can easily obtain a foothold. Many others enter at the pomt Where two fruits touch, or Where a leaf is ih' contact with a fruit. Still others are able to burrow into the exposed side of the fruit. The worm penetrates the skin and excavates a small cavity beneath it in an hour or so. It remains near the surface for a few days and then burrows to the center of the fruit, usually feeding chiefly on the seeds and Core. When full grown the worm makes a large tunnel to the surface through which it leaves the fruit. Wormy fruit is of small commercial value, since it will not keep long, and the laws of some States forbid its being shipped, except to byproducts p ants. A form of injury other than the tunneling is the sting (fig. Caused by a worm that started to burrow into the fruit and then died, usually as the result of feeding on poison spray On the fruit.
