J14 FARM FRIENDS AND FARM FOES. they are likely to nibble for a few days before they burrow down toward the core. When once within the fruit, they feed and grow for about a month. Then they leave the fruit and find shelter where they spin their cocoons, within which; they change to pupae. Each insect remains in this pupal state for about two weeks; then it emerges as an adult moth, like the one that laid the original eggs. These moths com- monly lay eggs for a second brood of worms, that de- velop in the apples throughout the late summer or early au- tumn months. The larvae leave the ap- ples when full grown and, in the shelter of rough bark or something similar, spin silken cocoons, within which they remain until about the time the apples blossom the following spring. Then they change to pupae, and change again in about two weeks to adult moths. There are two broods of these moths a year, each distributed over a long period. The injuries of the Codling Moth larvae may be pre- vented to a large degree by spraying with arsenical poisons in spring, soon after the petals of the blossoms have fallen. It is especially desirable that a thorough spraying be given before the calyx end of the young apple is closed. In the picture above, the calyx in each of the outer fruits is open; that of the larger, middle fruit is closed. By means of the spraying machine, the fruit grower is able to place in the Ap-piJEs SHOWING Calyx Open and Calyx Closed.
